INTRODUCTION
This Installation and Maintenance Guide provides an overall technical reference on the KAREL MS48 system and its accessories and includes descriptions, structures and capabilities as well as the installation and maintenance information. This guide is formed up of three main chapters: 1) Technical Reference: The system outline is given and all the accessories are described. Brief information about the software structure of the system is presented and finally the technical specifications of the system are listed. 2) Installation Guide: The basic system installation and wiring instructions are presented. Following the system installation part, the installation and the wiring of the accessories are explained. 3) Maintenance Guide: The basic steps to solve the problems faced after the installation of the system are given.

I. SYSTEM
At minimum capacity, MS48 has 4 lines and 12 extensions, which can be further upgraded to support the following configurations : Lines 4 6 8 10 12 Extensions 28 18 34 24 40 30 36

At minimum capacity, the MS48 system consists of the following parts : · · · · · CBN48 Cabinet made of metal, SPS48 Power Supply Module including a power card and cables, PWT48 Power Transformer, RNT48 Ring Transformer, MB48 Motherboard that can support the minimum capacity of 4/12.

The EXP48 Expansion Modules may be used to increase the system capacity.

MB48 MOTHERBOARD & EXP48 EXPANSION MODULES

The MB48 motherboard consists of the microprocessor, utility, DTMF, switching, line and extension circuitries. See the following figures for the location of these circuitries and the operational flow diagram of MB48 motherboard.

Figure A-3

Figure A-4

Karel MS48 Installation & Maintenance Guide Edition 3.2

The MB48 motherboard has 4 lines and 12 extensions, constructing the basic capacity of the system. However, this capacity may be further increased by means of EXP48 Expansion Modules. There are 3 types of EXP48 Expansion Modules : · · · EXP48 (4/12) Expansion Module with a capacity of 4/12. EXP48 (0/16) Expansion Module with a capacity of 0/16. EXP48 (2/6) Expansion Module with a capacity of 2/6.

At most two EXP48 Expansion Modules of any type can be installed on top of the MB48 motherboard except for both being EXP48 (0/16) or EXP48 (2/6), so that MS48 system supports the following capacities : Lines 4 6 8 10 12 Extensions 28 18 34 24 40 30 36

The default numbering plan of MS48 system depends on the system capacity as follows : · For capacities (4/12) and (6/18), the extensions have numbers 11 to 22 and 11 to 28, whereas the lines have numbers 01 to 04 and 01 to 06, respectively. For higher capacities, the extensions have three digit numbers, and the numbering of the lines is similar to the lower capacities. So, the extensions have numbers from 111 to 150 (max.) and the lines have numbers from 01 to 12 (max.).

·

When all the modules are installed and the system is powered on, the system checks and recognizes all the cards automatically and arranges the numbering plan accordingly. Other than the extension circuitries that exist on all EXP48 modules and the line circuitries that exist on all EXP48 modules except for EXP48 (0/16), there are also utility and switching circuitries on EXP48 Expansion Modules. See the following figures for the location of these circuitries, noting that the extension and line numbers are assigned with the assumption that the related EXP48 module is the first card installed on top of the MB48 motherboard.

Figure A-5.I

Figure A-5.II

Figure A-5.III As explained above, the DTMF circuitries exist on the MB48 motherboard, but not on the EXP48 modules. However, when the system capacity is increased beyond 6/18, the MF receiver capacity of the MB48 motherboard - that can serve 8 ports at a time - may be insufficient especially under heavy traffic. The MFR48 MF-Receiver Card that comes with each EXP48 (0/16) and EXP48 (4/12) module is designed to avoid such cases. MFR48 is to be installed on top of the MB48 motherboard when at least one of the two expansion modules is to be used. The MFR48 card has 2 MF receiver chips and thus increments the MF receiver capacity of the system by serving 4 extra ports at a time. The dimensions of MB48 are 19 cm x 35 cm and the weight is 0.75 kg. The dimensions of EXP48 (4/12) are 18.5 cm x 26 cm and the weight is 0.6 kg. The dimensions of EXP48 (0/16) are 18.5 cm x 23 cm and the weight is 0.4 kg. The dimensions of EXP48 (2/6) are 14.5 cm x 16.5 cm and the weight is 0.3 kg.

POWER TO THE SYSTEM

MS48 system receives 220 VAC from the mains. Inside the fuse slot next to the system ON/OFF switch, there exists a F-type fuse of 1 A / 250 VAC for the first step protection. The system can operate for the mains input of 180 - 260 VAC 50/60 Hz. The PWT48 Power Transformer generates 2x15 VAC from the mains voltage, which is processed by the SPS48 Power Supply Module. The PWT48 Power Transformer is located inside a metal cage at the up left corner of the CBN48 cabinet, together with the RNT48 Ring Transformer which generates 64 Vrms ring signal.

I.2.A. SPS48 POWER SUPPLY MODULE
SPS48 Power Supply Module is simply a card that resides below the metal cage surrounding the RNT48 and PWT48 transformers. SPS48 is a Switched Mode Power Supply (SMPS). Receiving 2x15 VAC from the PWT48 Power Transformer, SPS48 generates +5 VDC, +12 VDC and -24 VDC for the system operation, for the accessories and for the RNT48 Ring Transformer. The output of the RNT48 transformer is the 64Vrms ring signal, which is transferred to the MB48 motherboard directly. SPS48 also has connectors for KY16 Mini Printer and OP48(-H) Consoles / LT48(-H) Feature Phones / PG100 Local Pager / IA12 ISDN Adaptor. The Busy and Data signals on these connectors are not processed by SPS48, they are just received from the MB48 motherboard so as to be transmitted to the accessories. See the following figure for the location of the connectors on SPS48.

Figure A-6 The pin-out of the connectors on SPS48 module are illustrated in the following table:

MS48 system can be backed up with a battery of 12 VDC in order to provide the continuity of the operation in case of mains failure, by the help of the battery backup circuitries of SPS48. For the cases where a battery is to be connected to the system, it is strongly recommended to choose a dry battery for the proper operation. The MS48 system that is equipped with a 12 V ­ 7 Ah battery can continue to run for 5 hours under an average traffic of 35 %. There exists a connector on the SPS48 card for battery connection (see Figure A-6). The F-Type fuse of 8 A / 12 VDC for battery is also available on SPS48 card, residing at the down right corner of the power connector. SPS48 is also capable of charging the battery while the system power is on and the system is running under low traffic. Besides, there exists a low voltage battery cutoff circuitry, which turns itself off when the battery voltage goes below 8.5 VDC and does not start until the battery voltage is above 11.5 VDC. So, preventing full discharge of the battery SPS48 makes the lifetime of the battery longer. The SPS48 card also has the system buzzer that may be used as an external ringer for the incoming external calls. The dimensions of the SPS48 card are 11 cm x 11.5 cm and the weight is 0.3 kg.

I.2.B. POWER FAILURE TRANSFER STATIONS
In case of power failure the stand-by battery backup allows the system resume operation without any interrupt. In case there is no battery connected to the system when the power goes off, the lines on the MB48 motherboard and EXP48 (4/12) module are automatically connected to first 4 extensions of the same board. The same also applies to EXP48 (2/6), such that the lines on EXP48 (2/6) module are connected to the first 2 extensions of the same board, in case of power failure. See the following figure illustrating the power failure transfer stations of MS48 (10/30) system.

Figure A-7

I.3.

EXTERNAL MUSIC CONNECTOR

Any external music source (tape recorder, radio or CD player) can be connected to the system to be used for background music facility and to be transmitted to the external parties parked or put on hold. This connection is established via the 2-pin music connector on the MB48 motherboard.

I.4.

EXTERNAL RELAY

An external relay which is rated for 250 VAC - 24 VDC at a maximum current of 2 A exists on the MB48 motherboard to be used to activate either a door opener, an external ringer, an external music source or an external announcement system. The connection to the external relay is established through the 2-pin relay connector on the MB48 motherboard. The selection among these devices is made by programming.

Figure A-12 The dimensions of DSS80 are 16 cm x 22 cm x 6.5 cm and the weight is 0.7 kg.

II.1.D. DSS40 DIRECT STATION SELECT MODULE
The DSS40 Direct Station Select Module, which is used as an add-on module for OP48(-H) Consoles and LT48(-H) Feature Phones, consists of a BDP (Busy Display Panel), a 2-Character Display and a programmable keypad including 40 multipurpose keys and 40 corresponding LEDs. Each key may be programmed to activate two facilities, which may be calling an extension, accessing a line or activating a system feature. The corresponding LED of each key shows the status of the facility assigned to the primary function of the key. The BDP (Busy Display Panel) together with the 2-Character Display shows the states of 40 extensions and 12 lines as well as some system features. DSS40 can be used not only with the MS48 system, but also with the other KAREL systems of bigger capacities. That is why DSS40 handles 4-digit physical numbers for extensions, such that the 2-Character Display is used to show the most significant two digits whereas the LEDs on the BDP are used to indicate the least significant two digits. In this way, the two digits in the 2-Character Display may be interpreted as "page numbers", and there are 3 pages with numbers 11 to 13 that covers all the extensions in the KAREL systems to which DSS40 can be connected. It is also possible to navigate forward and backward among the pages, via the "+" and "-" keys on DSS40 keypad. However, when DSS40 is connected to MS48 system, it is enough to observe the first page (page 11) covering the extensions 1111 to 1150. The states of 12 lines as well as system features are displayed on all pages.

AUTO ATTENDANT & VOICE MAIL - EVM48

EVM48 Auto Attendant guides the external callers throughout their calls with prerecorded messages, and hence enables the operator to work more efficiently, especially under high traffic. Optionally, Voice Mail facilities may be employed, and then the extensions can have private voice mail boxes to be used to leave / receive messages to / from other users. EVM48 has 2 minutes Auto Attendant memory on board. Besides, EVM48 has two 36-pin connectors on the component side, which are used to install the optional EVM-FE (Auto Attendant Expansion) and three 24-pin connectors, which are used to install the optional EVM-DE (Voice Mail Expansion) cards. The EVM-FE card with a Flash ROM memory chip preserves the special messages for Auto Attendant purposes. At most two EVM-FE cards can be installed on the EVM48 card in addition to the onboard one. Each EVM-FE card has a message capacity of 2 minutes. Thus, EVM48 can have a maximum Auto Attendant message capacity of 6 minutes. 24 different messages to be used during different states of call handling of Auto Attendant can be entered. These messages are retained even when the system power is off. The EVM-DE card with two Dynamic RAM chips stores messages for the Voice Mail purposes. At most three EVM-DE cards can be installed on the EVM48 card. Each EVM-DE card can provide a total message capacity of 15 minutes. Thus, EVM48 can have a maximum Voice Mail message capacity of 45 minutes. The capacity per EVM-DE card may be also increased to 20 minutes by programming, in which case the voice quality is impaired to a certain extent, but the difference cannot be recognized by human ear. The Voice Mail messages are lost when the system power is off. EVM48 supports two voice channels, used by both Auto Attendant and Voice Mail facilities. That is, EVM48 can serve two users at a time, to record and listen to the messages. The two LEDs on the card are used to show the states of these voice channels. At start up, these LEDs blink till the system recognizes EVM48. Then, each LED stays on while the corresponding channel is idle and stays off when the corresponding channel is in use. The external callers can make use of the EVM48 facilities, only if they have DTMF telephone sets in order to be able to key in numbers whenever required by EVM48. The outlook of EVM48, EVM-FE and EVM-DE cards is illustrated in the following figure.

ISDN ADAPTOR ­ IA12, EXP-IA12

The IA12 ISDN Adaptor is an ETSI compatible terminal adaptor that serves as an interface between the ISDN BRA-S0 lines coming through the network terminator (NT1) of PTT and the analog lines of the MS48 system. The adaptor also supports many EURO-ISDN facilities for Basic Rate Access. The function of IA12 ISDN Adaptor is to support the ISDN BRA protocol of the network in order to make bi-directional conversions between the ISDN BRA lines of PTT and the analog lines of the MS48 system. At basic capacity, IA12 ISDN Adaptor is capable of handling one S0 line coming from NT1 of the PTT. This capacity can be further increased by means of an EXPIA12 Expansion Board which can also support one S0 line. Since each S0 line offers two separate channels, the IA12 alone can convert two analog lines of the MS48 system to one ISDN BRA-S0 line whereas the IA12 with EXP-IA12 can convert four analog lines to two ISDN BRA-S0 lines. The IA12 ISDN Adaptor communicates with the MS48 system through the data line of KAREL telephones. Due to the current limitation on this data line which also feeds the adaptor, it is not possible to connect more than three adaptors to the same system, and the third adaptor cannot have the EXP-IA12 Expansion Board. As a result, the available ISDN line capacities of MS48 system are illustrated as follows:

The IA12 motherboard has one 8-pin RJ45 socket for connection to the S0 line coming from NT1, two 623K4 type connectors for connection to the A / B terminals of the analog line on the MS48 system and one 6-pin RJ jack for connection to the data line of KAREL telephones. The data cable having a connection box at one end and a RJ45 plug at the other end also comes with the adaptor. The EXP-IA12 Expansion Board has one 8-pin RJ45 socket for connection to the S0 line coming from NT1 and two 623K4 type connectors for connection to the A / B terminals of the analog line on the MS48 system. The EXP-IA12 Expansion Board also comes with a flat cable for IA12 connection, which is to be attached to the corresponding 20 pin connectors on the IA12 motherboard and EXP-IA12 card. The IA12 motherboard also has three LEDs to display the status of S0 lines as well as the data line. The rightmost LED turns on when the adaptor is synchronized with the S0 line connected to the IA12 motherboard. The middle LED turns on when the adaptor is synchronized with the S0 line connected to the EXP-IA12 card. And the leftmost LED turns on when the adaptor is synchronized with the data line. The outlook of IA12 motherboard and EXP-IA12 card are illustrated in the following figures.

Figure A-19

Karel MS48 Installation & Maintenance Guide Edition 3.2

Figure A-20 The S0 lines connected to the IA12 adaptor may be Point to Point (that supports the connection of 1 device only) or Point to Multi-Point (that supports the connection of upto 8 distinct devices). Furthermore, as far as the numbering scheme is concerned, DDI (Direct Dialing In) may be active on Point to Point lines, or MSN (Multiple Subscriber Numbering) may be active on Point to Multi-Point lines. These settings are simply managed by the system software. The IA12 ISDN Adaptor also supports the following Euro-ISDN features, provided that the user has the subscription to the network, if necessary : · · · · · · · Calling Line Identification Presentation (CLIP) Calling Line Identification Restriction (CLIR) Connected Line Identification Presentation (COLP) Connected Line Identification Restriction (COLR) Advice of Charge at Call Setup (AOC_S) Advice of Charge During Call (AOC_D) Advice of Charge at the End of Call (AOC_E)

The IA12 ISDN Adaptor is capable of matching either "Speech" or "3.1 KHz Audio" bearer capabilities for outgoing calls as well. By way of the OP48(-H) or LT48(-H) telephones, several ISDN network messages including the number of the calling party and call charge information can be monitored. These network messages are also transferred to the CRL accessories. Neither MS48 system nor IA12 ISDN Adaptor has internal S0 ports, so it is not possible to connect an ISDN terminal to the extensions of MS48 system. However, it is possible to connect another ISDN terminal in parallel with the IA12 ISDN Adaptor in the Point to Multi-Point lines with MSN facility. The dimensions of IA12 are 10 cm x 21 cm x 7 cm and the weight is 0.9 kg. The dimensions of EXP-IA12 are 9 cm x 8 cm.

LOCAL PAGER ­ PG100

PG100 Local Pager lets you page extensions that are equipped with receivers (beepers) so that they can pick up their calls or attend later. The outlook of PG100 is illustrated in the following figure.

Figure A-21 KAREL also has its own beepers (receivers), which are adjusted to operate at the same frequency of PG100 and which are also programmable for the desired extension number as well as the PG100 Local Pager. IMPORTANT The operating frequency of PG100 Local Pager is 167.050 MHz. with a 25 KHz. Bandwidth. The coverage area of PG100 is 200 m indoor and 2 km open air. The Data cabling of PG100 Local Pager is made via the 3-pin CONSOLE connector on the SPS48 card. The signaling between the SPS48 and PG100 is illustrated in the following table:
SPS48 Card CONSOLE Connector Pin No 1 2 3 Signal Data +12 VDC GND PG100 Card RJ Plug Pin No 1 6 2

The input of +8 VDC is regulated to +5 VDC by PG100. PG100 can be also directly connected to mains voltage through a 12 VDC power adaptor. Normally, PG100 receives power over the data cable. However, if the data line of the system is overloaded due to the existence of many OP48(-H) and LT48(-H) telephones or DSS40 and DSS80 modules connected to the system, it is preferable to feed PG100 over the power adaptor that is to be procured locally. The dimensions of PG100 are 24 cm x 19 cm x 4.5 cm and the weight is 0.5 kg.

FILTER & PROTECTION UNIT ­ FPBASE, FPEXP

The external lines that are connected to the system and the extension lines coming from other buildings are open to environmental effects like lightning or AM radio interference. In order to protect the system against lightning and radio interference, KAREL has external modules that can be connected to both extensions and lines. These modules are presented in two different models: a) FPBASE Filter & Protection Base Unit, b) FPEXP Filter & Protection Expansion Unit. Both units are capable of handling four lines. The difference between FPBASE and FPEXP is the base cover, which exists only on FPBASE unit. FPEXP units are installed on top of an FPBASE unit. So, if a Filter and Protection Unit is required for a system then an FPBASE unit must be used and depending on the capacity of the ports that must be filtered and protected, FPEXP units can be added. The outlook and structure of FPBASE and FPEXP units are illustrated in the following figure.

Figure A-24 The dimensions of the FPBASE are 18 cm x 12 cm x 3 cm and the weight is 0.4 kg. The dimensions of the FPEXP are 17 cm x 12 cm x 2.5 cm and the weight is 0.3 kg.

III. SOFTWARE
MS48 system is a Stored Program Controlled (SPC) system. It has a microprocessor, which controls the operation of the system; and an eprom that stores the software of the system. All the default system and extension / line parameters are stored in the EPROM. Though MS48 is a small capacity system, the software is designed to provide a full feature system. There are three categories for the features of the system: 1) User features, 2) Operator features, 3) Programs. User features are the software facilities, which may be activated by any user of the system. Operator features are the software facilities, which may be activated only by the operator of the system. The operator is the first extension of the system, i.e. the extension who has the physical access code "11" or "111" depending on the capacity of the system. Programs are the codes that may be entered only either by the system supervisor or the operator after the system is put in programming mode by the system supervisor. By default, the operator is the system supervisor. By programming, most of the parameters, which control the operation of the system, can be changed. The software facilities are given in the relevant guides together with their details.

II. SYSTEM INSTALLATION
The MS48 system is designed to be mounted on the wall. Hence, the system comes with a template and a pair of anchor plugs with screws. Another pair of screws that are used to fasten the front cover are also available. The template has the same dimensions with the MS48 system, so that it can be used to choose the location of the system and to determine the points of the holes on the wall. The template also has the necessary information to hang the system on a proper location on the wall, which is illustrated in the following figure.

Figure B-1 To install the system (see Figure B-2) : 1) 2) 3) 4) 5) Place the template on the wall. Drill two holes at the points marked as X1 and X2 on the template. Drive the anchor plugs into the holes. Insert the screws into the anchor plugs and fix the screws. Hang the cabinet on the wall by placing the two pear holes at the back of the cabinet over the screws.

Karel MS48 Installation & Maintenance Guide Edition 3.2

35

Figure B-2 It is recommended to close the front cover after the cabling of extensions / lines and accessories is completed, by inserting the two screws into the holes on the right side of the front cover (see Figure B-2). IMPORTANT The equipment can be installed only by the service personnel. The area behind the front cover is not for operator access, hence the front cover can be opened only by the service personnel. The mains socket should be installed near the equipment or should be easily accessible.

II.1.

GROUNDING

There are two different ground terms in MS48 system. a) One is the signal ground, which takes place on the MB48 motherboard as well as the add-on cards. It serves as a reference for the signals on the cards. b) Second is the chassis ground. The subject of this section is chassis ground, which has an utmost importance for the protection of the system against any lightning, or any high voltage coming through external lines, extensions or mains.

36

Karel MS48 Installation & Maintenance Guide Edition 3.2

The chassis ground is established through the mains cable of the system, which is equipped with the ground wire. Therefore, if the mains outlet has a proper ground, there is no need to make any extra connections for the chassis ground. Due to this reason, it is recommended to operate the system over a mains plug that is properly grounded. Checking whether the mains ground is proper or not requires special devices. But it is possible to have a rough idea about the mains ground simply by measuring the voltage across: · · The phase and the neutral; it must be in range of 180 VAC and 260 VAC. The ground and the neutral; it must be 1-2 VAC.

If mains ground is not satisfactory, the system chassis can be connected to a hot or cold water pipe, which may serve as the ground surface of your system, through the ground screw (labeled with ) at the down left corner of the system cabinet, to which the ground wire of the mains cable is connected. For such cases, it is of course better to construct an ideal ground, simply by inserting a metal bar (of at least 1.5 m length and 1.5 cm radius, copper is preferable) into the earth, as illustrated in the following figure.

Figure B-3

II.2.

SPS48 POWER SUPPLY MODULE

The SPS48 Power Supply Module, including the power card with cables, comes already installed in the system cabinet, below the metal cage surrounding the RNT48 and PWT48 transformers. The SPS48 card is connected to MB48 motherboard via the 7-pin flat cable. Also, the 3-pin connector at the end of the cable coming from PWT48 power transformer as well as the 4-pin connector at the end of the cable coming from RNT48 ring transformer are attached to the corresponding connectors on SPS48 card. The output of the RNT48 ring transformer, which is in fact the ring signal itself, is directly transferred to the MB48 motherboard. For this, the 2-pin connector at the end of the cable coming from RNT48 is attached to the corresponding connector on MB48.
Karel MS48 Installation & Maintenance Guide Edition 3.2

37

These connections are illustrated in the following figure.

Figure B-4 The free space inside the system cabinet, below the SPS48 card, is reserved for the battery, which can be attached to the system cabinet via the metal bars that can be supplied on demand. IMPORTANT The ventilation holes on the front cover of the system cabinet must not be closed for any reason, since it may cause SPS48 to overheat and get damaged.

II.3.

MB48 MOTHERBOARD & EXP48 EXPANSION MODULES

The MB48 motherboard comes installed in the cabinet. It stays on the brass card holders that are attached to itself by screws. One of the brass card holders together with its screw ­ the one passing through the M4 hole at the right side of the motherboard ­ is used to carry the chassis ground to the motherboard and add-on cards. The MS48 system can have at most two EXP48 Expansion Modules, that are addon cards to be installed on the MB48 motherboard. In such a case, the first EXP48 card is located on the motherboard and the second one is placed on the first one. In such a situation, the EXP48 (2/6) card cannot be the first card located on the motherboard. Rather, it must be placed on the other EXP48 card, due to its smaller dimensions. Such an installation can be established simply as follows: There exist several male connectors on the solder side of each EXP48 card. The female correspondents of these connectors are also available on each EXP48 card together with the MB48 motherboard. The following figure illustrates the location of these connectors on the EXP48 cards as well as the MB48 motherboard.

38

Karel MS48 Installation & Maintenance Guide Edition 3.2

Figure B-5 For the installation of each EXP48 card, the male connectors on the card itself must be attached to the female correspondents on the card underneath, which may be either the MB48 motherboard or another EXP48 card. After that, it is necessary to fix the EXP48 cards by way of brass card holders and screws. One of the brass card holders together with its screw ­ the one corresponding to the M4 hole of the motherboard ­ is used to carry the chassis ground to the EXP48 card. The following figure is to demonstrate the installation of EXP48 cards briefly.

Figure B-6 IMPORTANT Make sure that : 1) All the pins of male connectors on the EXP48 cards are matched to the corresponding pins of the female correspondents on the card underneath properly. 2) All the brass card holders of each EXP48 card, especially the ones that carry the chassis ground, are fixed properly.
Karel MS48 Installation & Maintenance Guide Edition 3.2

39

As the last step in the installation of EXP48 modules, the MFR48 MF-Receiver Card that comes with EXP48 (4/12) or EXP48 (0/16) must be installed on the MB48 motherboard. For this, the two male connectors on the solder side of MFR48 card must be attached to the female correspondents on the up left corner of the MS48 motherboard. After that, it is necessary to fix the MFR48 card to the MB48 motherboard using one brass card holder with its screw and washer. The following figure illustrates the installation of MFR48 card.

III. ACCESSORY INSTALLATION
III.1. CONSOLES, FEATURE PHONES, DIRECT STATION SELECT MODULES

· CABLING
Each LT48(-H) Feature Phone, OP48(-H) Console and DSS40 / DSS80 Direct Station Select Module comes with a telephone data cable, which is a 2.5-meter long cable formed up of two parts. One is a cable with a 6-pin RJ plug at both ends and the other one is a connection box. The connection box has a 6-pin RJ socket at one side so that one of the free ends of the cable can be fixed to the connection box easily. The other free end of the cable has also the corresponding RJ socket at the backside of the telephone or DSS module. The system itself also comes with the system data cable, which is similar to telephone data cable. One end of the cable is fixed to the connection box. The other free end of the cable has a 3-pin connector, which is to be inserted to the CONSOLE connector on the SPS48 card, in order to carry data signals for the telephones and DSS modules. The following signals are present on the connection box of system data cable:

123456-

Data signal Ground (GND) No connect No connect Busy + 12 VDC

Note : Busy signal is for KY16 Mini Printer.

Figure B-8

Karel MS48 Installation & Maintenance Guide Edition 3.2

41

The following signals are present on the connection box of telephone data cable:

123456-

Data Signal Ground (GND) A (ring) signal from the connector of the relevant extension port. B (tip) signal from the connector of the relevant extension port. No Connect + 12 VDC

Note : On the connection boxes of DSS40 and DSS80 modules items "3" and "4" are "No Connect".

Figure B-9 To make the cabling of each LT48(-H) Feature Phone, OP48(-H) Console and DSS40 / DSS80 Direct Station Select Module : 1) The free end of the system data cable must be passed through the hole on the panel at the down left corner of the system cabinet (the panel on which the system ON/OFF switch resides) and then attached to the CONSOLE connector on SPS48 card. The Data / + 12 VDC / GND signals on the connection box of the system data cable must be wired in parallel to the corresponding pins of the connection box of the telephone data cable. The RJ plug at the free end of the telephone data cable must be inserted into the female correspondant on the telephone or DSS module. At this point, the cabling of DSS40 and DSS80 modules is completed, as there are no A / B terminals for these modules. However, for each OP48(-H) and LT48(-H) telephone, the wiring of the A / B terminals must be made separately, by connecting the wires of the cable coming from the corresponding extension connector on MB48 motherboard or EXP48 card to the A / B terminals (the terminals with red and green wires) in the connection box of the telephone data cable.

2)

3) 4)

The following figure illustrate the cabling of OP48(-H) Consoles, LT48(-H) Feature Phones and DSS40 / DSS80 Direct Station Select Modules.

42

Karel MS48 Installation & Maintenance Guide Edition 3.2

Figure B-10 In case there is a LT48(-H) Feature Phone or OP48(-H) Console located near the system, the method of Data / +12 VDC / GND cabling for this telephone may be simplified by connecting one of the RJ plugs on the telephone data cable to the RJ socket on the connection box of the system data cable.

·

FIXING DSS40 / DSS80 MODULES TO OP48(-H) / LT48(-H):
Each DSS40 or DSS80 module comes with a plastic telephone connection part, used to fix the module to the LT48(-H) or OP48(-H) telephone of the relevant extension. To fix the DSS40 or DSS80 module to the LT48(-H) or OP48(-H) telephone (see Figure B-11) : 1) 2) 3) 4) Remove the screw at the bottom of the telephone. Remove the two screws at the bottom corners of the DSS module. Place the plastic telephone connection part in-between the telephone and the DSS module. Insert the screws to the telephone and DSS module.

Karel MS48 Installation & Maintenance Guide Edition 3.2

43

If there are several DSS modules connected to the same extension, each extra DSS module can be connected to the previous one as explained above.

Figure B-11

·

NUMBER OF TELEPHONES & DISTANCE TO THE SYSTEM:
Please also note that : 1) OP48(-H) Consoles, LT48(-H) Feature Phones and DSS80 / DSS40 Direct Station Select Modules can be connected to the first 16 extensions of the system. The total number of OP48(-H) Consoles, LT48(-H) Feature Phones and DSS80 / DSS40 Direct Station Select Modules connected to the system must not exceed 10.

2)

If the Data / 12 VDC / GND and A / B (ring / tip) wires of a console or a feature phone are carried separately as described in the "Cabling" part above, the console or feature phone can be installed more than 5 meters away from the system. In such a case, the maximum distance between a single feature phone, console or DSS module and the system can be 250 meters, if the wiring is made with ordinary wires. However, if more than one set will be installed to the system and if the Data / 12 VDC / GND wires of the sets are wired in parallel as described in the "Cabling"

44

Karel MS48 Installation & Maintenance Guide Edition 3.2

part above, the maximum distance of 250 meters decreases proportionally. For example, if 10 LT48 Feature Phones are connected to the system in this way, the distance between the system and the LT48 Feature Phones cannot exceed 25 meters. In such a case, the performance can be further improved by connecting +12 VDC power supply, if the data voltage of the ultimate console is below +8.5 VDC, between 12 VDC and GND terminals.

·

EXTENSION NUMBER SETTING :
After the wiring of the OP48(-H) Consoles, LT48(-H) Feature Phones and DSS40 / DSS80 Direct Station Select Modules, the extension setting of these sets should be made as follows : a) OP48(-H): The setting is made by the "Message" key. Keep the key pressed till the extension number starts blinking on the display and "A" appears next to it. Then, press the same key several times till the correct extension number appears on the display. LT48(-H): The setting is made by the "H/R" key.
