enough, make a new and proper earth connection to the system to avoid possible hazards

that may occur due to the high voltages which may affect the system.

♦ For the wall type systems, the rack holder metal part must be 100 cm above from the

floor level.

♦ It must not be permitted to install the system into the places:

• Exposed to direct sunlight,

• Extremely hot and cold places,

• Where the temperature is out of the range of 5 C

to +40 Co and the relative humidity

is above 80%,

• Where vibrations or shocks are frequent or strong,

• Close to radio broadcast antennas,

• Where the system may be in contact with water, oil or dust,

• Close to Sulfuric gas producing areas like thermal springs, etc. that may damage the

system,

• Near high frequency sewing machines or electric welders.

♦ The frequent power cut-off may affect the performance of the system. Therefore, make

sure the system has an uninterrupted power source specific to the system.

♦ Anything, which may prevent proper ventilation of the system may be risky and affect the

performance of the system.

Preface

The two chapters in this guide are prepared to supply detailed information for the people who

may need detailed technical information about the structure and installation of the system.

Thus, the methods to configure the system to meet the customer requirements can be

learned from this guide.

The first chapter – “Technical Reference Guide” - gives detailed information about the

hardware and the software structure of the DS200 systems. The information in this chapter

may require some background on mechanics, electric and electronics. The information flow

goes from the whole to the pieces forming up the whole. At the end a table of summary can

be found.

The second chapter – “Installation Guide” – explains the methods to configure the system in

a proper way and to meet all the customer requirements. Also the steps to run the system

and the items to be inspected at the first run time are explained in this chapter. This chapter

must be read carefully by the personnel who will make the installation of the system.

Best regards,

KAREL

I. SYSTEM DEFINITION

DS200 series exchanges are TDM based IP enabled communication systems. The systems have distributed processor structure. The TDM switching part is based on different interface boards and relevant protocol implementations on these relevant interface boards. Therefore, the system's TDM structure is a modular structure, thus the system TDM capacity can be increased by simply adding desired boards to the system.

The IP structure, on the other hand, is a software based structure. The IP capabilities of the system come embedded on the main CPU and can be activated by the appropriate licensing options. Therefore except for the media gateway channels no additional hardware is required for the IP channels.

The DS200 series systems have different software options with different capacities. Below is the complete family of DS200 series systems:

System Name Max Capacity DS200M 144 TDM + 750 IP ports DS200S 224 TDM + 750 IP ports DS200 1344 TDM + 750 IP ports DS200L 32000 TDM + 5000 IP ports

I.1. DS200

DS200 is a large-capacity telephone branch exchange, whose capacity can be extended to 672 lines and to 1344 lines, for three-rack and six-rack structures, respectively. The system supports maximum 750 IP ports. Due to its distributed CPU structure, it is a very reliable and flexible communication system, which is open to development.

DS200 can be configured in two different mechanical structures, namely wall or cabinet type: The wall-type DS200 can be configured in two structures: the single-rack type (with cover) which can be extended to a maximum of 224 lines, and the two-rack type (with cover) which can be extended to a maximum of 448 lines. As for the cabinet-type DS200, it can be configured in the following structures:

- Single-rack (224 lines at the maximum),

- Two-rack (448 lines at the maximum),

- Three-rack (672 lines at the maximum),

- Four-rack (896 lines at the maximum),

- Five-rack (1120 lines at the maximum),

- Six-rack (1344 lines at the maximum)

In that structure, the system can reach a capacity of six racks by the use of two cabinets.

The figures below illustrate general appearances of the wall-type DS200 system and the cabinet.

Page 17

DS Series PBX Technical Reference And Installation Guide

Page 18

Racks constitute the basis of the mechanical structure of DS200. There are two types of rack structure used in the DS200 systems, namely Main Rack and Auxiliary Rack

The both types of racks have 14 general-purpose slots for the same EX200 interfaces; however, the CPU200 and DS200 CPUKON cards are situated only in the main rack. Therefore, there are special slots for these cards in the main rack, whereas those slots are not present in auxiliary racks. As a result, backplanes of the main rack and auxiliary racks are different (BPL200-MAIN and BPL200-AUX) and they cannot be used interchangeably.

I.2. DS200S

DS200S is a medium-capacity digital telephone branch exchange in a single-rack structure, which has been designed to be mounted on wall, and whose capacity can be extended to 224 lines. Similar to DS200 system, DS200S supports 750 IP ports. Due to its distributed CPU structure, it is a very reliable and flexible communication system that is open to development.

The figure below illustrates the general appearance of the DS200S system.

DS200S

Page 20

I.3. DS200M

DS200M is a medium-capacity digital telephone branch exchange in a single-rack structure, which has been designed to be mounted on wall, whose capacity can be extended to 144 lines. Similar to DS200 system, DS200M supports 750 IP ports. Due to its distributed CPU structure, it is a very reliable and flexible communication system that is open to development.

The figures below show the general appearance of the DS200M system.

DS200M

I.4. DS200L

The system hardware consists of TW200 (Tower200) towers, the PCU200 (PC Unit) Block, the DCC Block, a network switch, power inverter and the external power block ( if SPS200 is not used). In the figure below, DS200L system in a 6-rack and 19” cabinet is illustrated. (There are 2 TW200 towers in the figure).

Fundamental differences of the DS200L system from the DS200 system are briefly as follows:

• DS200L has high capacity up to 32000 ports,

• The PCU200 Block fulfills the tasks of the CPU200 card,

• DS200L has the DCC Block for high capacity switching,

• The units communicate over LAN with TCP/IP protocol,

• It is necessary to install Utility 4E1 cards on UTIL200 cards,

• It is possible to utilize the CC cards in main racks, instead of the CPU200 card ,

• External power block is utilized instead of the SPS200 power supply at high

capacities,

• DS200L utilizes power inverter and network switch.

Page 22

I.5. COMMON UNITS

DS200S and DS200M exchanges are two systems that have been designed to meet different capacity needs, although they have the same structure. In this regard, it is a natural fact that many units are employed in both exchanges. Such common units are called ‘the DS200S unit’ throughout the rest of the guide; so one should keep in mind that the units mentioned in this way can be employed in both the DS200S and the DS200M exchanges.

DS Series PBX Technical Reference And Installation Guide

II.1.E. INTER-CABINET CONNECTION UNITS

If the required DS200 capacity necessitates a configuration with four or more racks, such a structure is accomplished by some intelligent units of the racks located in both cabinets, which connect the two cabinets to each other.

In order for the inter-cabinet connections to be made, the revision of the CPU200 card must be R01C.01 or higher, and the revision of the BPL200-MAIN backplane must be R03B.02 or higher.

Information about the cards used for that purpose is as follows.

II.1.E.1. CCU CARD

The CCU card is a card employed in the second three-rack cabinet, which receives signals from the CPU200 card located in the first three-rack block, and which distributes these signals to the second block after amplifying them. Due to its structure, it is attached to the special slot reserved for the CPU200 in the main rack of the second block and it transports the signals to the second block over a 64-pin female connector at its back.

The LED on the front face of the CCU card blinks during normal operation.

II.1.E.2. CLOCK MASTER & CLOCK SLAVE CARDS

The Clock Master is installed in the block in which the CPU200 card is located and the Clock Slave is installed in the block in which the CCU card has been installed. Since there is no connector at the back of these cards to provide connection to the backplane, they can be attached in any vacant slot in the system, which is easily reachable in order to facilitate mounting. (See the DS200 Series Installation Guide, for the convenient slots)

These two cards function as a bridge carrying the PCM channels between the cabinets. The necessary connections between the cards are made through special cables provided by Karel.

Five identical eight-wire cables with RJ45 connectors at both ends are used for those connections. As can be deduced from that fact, number of signals carried between the two cards is (8 x 5) 40. Indeed, the number of signals that is to be used actively is 20, however, a ground line is carried with each signal in order to increase the reliability of the carried signals, so that the signals are affected by the external factors at a minimum.

Page 34

II.2. DS200S

II.4. DS200L

Six-rack cabinets are used in the DS200L systems. 2 of TW200 towers can be installed into six-rack cabinet. The rack structure of TW200 is similar to the usual DS200 rack structure. The main differences are that; CC card is used instead of CPU200 and Utility 4E1 card can be mounted on to the UTIL200 card. Furthermore, redundant CC card can not be installed. 1 TW200 tower consists of 1 main rack and maximum 2 auxiliary racks. TW200 racks consist of the parts below:

• RACK200 basic metal rack structure

• SPS200 AC/DC Power Supply (for small capacities)

• SPS248 DC/DC Power Supply

• BPL200-AUX Backplane (only for auxiliary rack)

• BPL200-MAIN Backplane (only for main rack)

• BPL200-SPS Backplane or BPL200-SPSX Backplane

• The UTIL200 Utility Card and the Utility 4E1 card

• The EX200 Expansion Modules (at most 14 modules)

II.4.A. RACK STRUCTURE OF TW200 (TOWER 200)

A TW200 tower consists of maximum 3 TW200 racks, namely a main rack and two auxiliary racks. (In fact, only a single main rack is enough to establish a tower.) The rack structure of TW200 is same as the DS200 rack structure (see section II.1.B). The UTIL200, CPUKON and other cards that are used in DS200 racks are also used in TW200 racks. However, since the PCU Block functions as the main processor in the DS200L system, no CPU200 card is available. The CC200 card is employed instead of the CPU200 card. Necessary information on the CC200 and UTILITY 4E1 cards are supplied below.

II.4.B. THE SIX-RACK CABINET

Six rack slots are available in this cabinet, which are required to install a system with at most six racks. Hence, it is used for six-rack systems. Two TW200 towers of the DS200L systems can be placed in a 6-rack cabinet.

Details regarding the elements of a 6-rack cabinet have been illustrated in the figure below.

III. BACKPLANES

III.1. DS200

III.1.A. BACKPLANE OF THE MAIN RACK - BPL200MAIN

Definition:

BPL200-MAIN constitutes the backbone of the main rack. It is the card, on which CPU200, UTIL200, EX200 modules and the backplane of power supplies (the BPL200-SPS backplane) are plugged, and it is the card that provides the fundamental communication of the system, as well as the connection to the other racks. On the backplane, there are 14 card connection slots for EX200, two for CPU200 and one for UTIL200. Besides, there are connectors located on this card for the auxiliary rack and the SPS backplane.

The figure below shows structure of the BPL200-MAIN backplane and the connectors located on it.

IV. POWER SUPPLIES

IV.1. DS200

The system operates on 230 VAC / 50 Hz mains input that is processed by SPS200 and SPS248 Power Supply modules. Therefore, a single SPS200 and an SPS248 have been included in each rack within the basic hardware structure of the system.

Yet, the DS200 system can be fed by an external AC/DC power supply of 56 VDC, if necessary. In that case, since the SPS200 AC/DC power supplies are not used, the SPS248 DC/DC power supplies may be used as a backup, upon wish. (In that case, the BPL200SPSX backplane must be used, too.)

IV.1.A. THE AC/DC POWER SUPPLY - SPS200

Definition:

SPS200 is a Switched Mode Power Supply that operates on the mains voltage (SMPS). Appearance of the SPS200 AC/DC Power Supply is illustrated in the figure below.

A. Mains Side B. Battery Side C. Connection Plane D. Control & Monitor Plane 1. Power Status LEDs 2. Battery On/Off Switch

3. Mains On/Off Switch 4. Battery Fuse 5. Mains Fuse Compartment

6. Mains Socket 7. Battery Connectors

The SPS200 AC/DC Power Supply converts 230 V AC to -56V DC, which is the input value for the SPS248 DC/DC Power Supply. SPS200 can also feed the system through batteries and it can charge the batteries while being fed from the mains. In addition to that, it protects the exchange from adverse factors that may affect through the electric system.

Page 49

DS Series PBX Technical Reference And Installation Guide

Technical Information:

SPS200 operates on 230 VAC from the mains input. Its alternative current input has been designed so as it is not affected by variations within the range +/- %10. There are two T-Type 2A / 250 VAC fuses in the main fuse compartment as the first-step protection for the phase and neuter lines.

The SPS200 AC/DC Power Supply has been connected to the 5-pin connector on the BPL200-SPS Backplane and it has been screwed into the upper front part of the metal rack. The SPS fixing screw must be loosened before the SPS casing is removed from the exchange. It is not obligatory to use that screw after mounting, which has been included just to provide safety during transportation.

The SPS200 AC/DC Power Supply contains a metal casing to which the SPS200CR Power Card is connected. The mains transformer is located on the SPS200CR Power Card.

SPS200CR, which gets 230 VAC over mains, generates –54 VDC, which is the input voltage to SPS248. Pin-outs for the SPS200 connector on the BPL200-SPS backplane are as follows:

SPS200 – BPL200-SPS Connector

Pin no

2 ISOGND

5 - VOUTREL

The DS200 system may be backed up with the 48 VDC battery support in order to maintain operation in case of power failures. Hence, the necessary battery backup circuitry is present on SPS200CR. Since the system does not include embedded power failure transfer stations, battery backup is vitally important for maintaining connection of the system to the outer world in case of power failure. Considering the battery connection in this regard, use of dry-type batteries is strongly recommended in order to maintain proper operation of the system. A battery connection of 48V/24 Ah is recommended for a full capacity, three-rack system with a traffic rate of 35 % in average.

There is also an F-Type 8A/48VDC fuse on SPS200 for the battery input.

SPS200CR has the ability to charge the batteries even when the system power is on and the system is operating with a low traffic rate. In addition to that, there is also a low current cutoff circuit that turns itself off when the battery voltage drops below 42 VDC, and which is not turned on until the voltage level rises above 48 VDC. Thanks to this circuit, SPS200 would prolong life of the batteries by preventing their full discharge.

The counterpart of the SPS200 backplane connector (with 4 pins) is also located on the outer side of the metal chassis on the back surface of the rack. Those connectors are also supposed to be connected to one another during installation of systems with several racks, with cables that come as attached to those connectors.

Page 50

Operational Information:

Three LEDs that are on the front panel of the SPS200 Power Supply Module help to figure out the power supply that is in use at that moment.

The first of those LEDs is for 230 VAC (with the “Mains Power” tag), the second one is for – 56 VDC (with “VOUT” tag) and the third one is for fault detection (with “Fault” tag). When the system is being fed from the mains supply during normal operation, the “Mains Power” and “VOUT” LEDs light up. The “Mains Power” LED is turned off when the mains supply is cut. In that case, if the battery backup is active, then the “VOUT” LED remains on. If a problem with the system power occurs, the “FAULT” LED lights up. In that case, the system must be shut down.

In a multi-rack system, there are several SPS200 Modules, which are connected to each other in parallel over inter-rack SPS connections. Therefore, in normal conditions, if the system traffic load is not extreme, just one or two of the SPS200 modules operate, while the other(s) is (are) in standby mode. LEDs of the SPS200 that is in standby mode are off. Once the SPS200 gets into operation, its LEDs are turned on.

There are also Mains and Battery On/Off switches on SPS200. In a wall-type system, those switches are accessible even when the front cover is closed.

In a cabinet-type system, in addition to the on/off switches on SPS200, a primary mains switch for mains input, which is protected by a 10 A / 250 VAC, T-type fuse, is situated in the lower front section of the cabinet. Likewise, the primary battery switch, which is protected by a 10 A / 250 VAC, T-type fuse, has been placed right below the primary mains switch. It is required to open the front cover of the cabinet in order to reach primary mains and battery switches.

Page 51

DS Series PBX Technical Reference And Installation Guide

The mains On/Off switch is supposed to be set to position “1” for normal operation. Moreover, in order to put the battery into operation in the systems with battery connection in case of power failures, the battery switch is also supposed to be set to position “1”. While the system is being put into operation, the mains switch is supposed to be set to “1”, even in cases where battery connection is present, and the battery switch is supposed to be set to “1” after the system has started to operate.

* AS FOR THE CABINET-TYPE SYSTEMS, IN ORDER TO TURN ON/OFF

THE SYSTEM, THE PRIMARY MAINS AND THE PRIMARY BATTERY SWITCHES

MUST BE TURNED ON AND TURNED OFF, RESPECTIVELY. THE BATTERY AND

MAINS SWITCHES ON SPS200 ARE FOR SECONDARY CONTROL ONLY.

TURNING SPS200 SWITCHES ON AND OFF, BEFORE TURNING THE PRIMARY

MAINS AND THE PRIMARY BATTERY SWITCHES OFF, MAY DAMAGE SPS200.

Dimensions of SPS200 are 8 cm. x 22.5 cm. x 20 cm. and it weighs 2.8 kg.

IV.1.B. THE DC/DC POWER SUPPLY - SPS248

Definition:

It is the power supply that generates voltages and the ringer signal, which are required for the system, from - 56 VDC it receives from SPS200. The figure below shows the appearance of the SPS248 DC/DC Power Supply.

The SPS248 DC/DC Power Supply converts the -56 VDC output of the SPS200 AC/DC Power Supply to the voltage levels of +5 VDC, -5 VDC and -48 VDC that are required for system operation. Besides, there is a ringer transformer on SPS248 for generating ringer signal (67 Vrms.)

Technical Information:

The SPS248 DC/DC Power Supply is plugged into the 64-pin power connector that is on the BPL200-SPS backplane and it is fixed to the upper front part of the metal rack with a screw.

The SPS248 DC/DC Power Supply contains a metal power rack onto which the SPS248CR Power Card and the ringer transformer are connected.

Outputs of SPS248CR and the ringer transformer are transferred to the BPL200-SPS backplane over the 64-pin power connector. The backplane carries these outputs to the BPL200-MAIN / BPL200-AUX sections. Pin-outs for the SPS248 connector on the BPL200SPS backplane are as follows:

Operational Information:

There are three Power Status LEDs on the front panel of the SPS248 Power Supply. The first, second and third LEDs are for -5 VDC, +5 VDC and -48 VDC, respectively. Normally, all three LEDs are supposed to light up when the system power is switched on. If there is problem with one of the DC voltages, then the related LED goes off.

Dimensions of SPS248 are 8.2 cm. x 22.5 cm. x 20 cm. and it weighs 3.15 kg.

IV.2. DS200S & DS200M

IV.2.1. THE POWER SUPPLY - SPS200M

The DS200S and DS200M systems operate on the 230 VAC / 50 mains supply, which is processed by the SPS200M Power Supply Module. SPS200M comes on a metal chassis which is open at the top and all sides.

The SPS200M AC/DC-DC/DC Power Supply first converts 230 V AC to –56 VDC within itself. Then, it converts the -56 VDC output to the voltage levels of +5 VDC, -5 VDC and -48 VDC that are required for system operation. Besides, there is a ringer transformer on it for generating ringer signal (67 Vrms.) The power supply can also feed the system through the battery and it can charge the battery while being fed from the mains voltage. In addition to that, it protects the exchange from adverse factors that may affect through the electric system.

SPS200M Power Supply contains a metal casing to which the Power Card is connected.

Technical Information:

SPS200M operates on 230 VAC from the mains. Its alternative current input has been designed so as it is not affected by variations within the range +/- %10. There are two T-Type 2A / 250 VAC fuses in the main fuse compartment as the first-step protection for the phase and neuter lines.

The SPS200M Power Supply has been connected to the 10-pin connector on the BPL200SSPS Backplane and it has been screwed to the upper front part of the metal rack. The SPS fixing screw must be loosened before the SPS casing is removed from the exchange. It is not obligatory to use that screw after mounting, which has been included to provide safety during transportation.

The DS200S/DS200M system could be backed up with 48 VDC batteries in order to maintain operation in case of power failures. Therefore, there is the necessary battery backup circuitry on the power supply. Since the system does not have embedded power failure transfer stations, battery backup is essentially important for maintaining connection of the system to the outer world. Considering the battery connection in this regard, use of dry-type batteries is strongly recommended in order to maintain proper operation of the system. A battery connection of 48V/19 Ah is recommended for a full capacity system with a traffic rate of 35 % in average.

There is also an F-Type 8A/48VDC fuse on the power supply for the battery input.

The power supply has the ability to charge the batteries even when the system power is on and the system is operating with a low traffic rate. In addition to that, there is a low current cut- off circuit that turns itself off when the system voltage drops below 34 VDC, and which is not turned on until the voltage goes above 46 VDC. Thanks to this circuit, the power supply would prolong life of the batteries by preventing their full discharge.

Operational Information:

Three LEDs that are on the front panel of the SPS200M Power Supply Module help figure out the power supply that is in use at the moment.

The first of those is for 230 VAC (with the “Mains Power” tag), the second one is for –48 VDC and the third one is for +5 VDC. When the system is being feed from the mains supply during normal operation, all LEDs light up. The “Mains Power” LED is turned off in the absence of mains voltage. In that case, if battery backup is available, then the LED for –48 VDC remains on. In the event that a problem with the + 5VDC supply in the system occurs, the LED for + 5VDC goes off. If that is the case, the system must be shut down.

There are also Mains and Battery On/Off switches on SPS200M. In the DS200S/DS200M system, those switches are accessible even when the front cover is closed.

Page 56

The Mains On/Off switch is supposed to be set to position “1”, for normal operation. Moreover, in order to put the battery into operation in the systems with battery connection in case of power failures, the battery switch is also supposed to be set to position “1”. While the system is being put into operation, the mains switch is supposed to be set to position “1”, even in cases where battery connection is present, and the battery switch is supposed to be set to position “1”, after the system has started to operate.

Dimensions of SPS200M are 8,2 cm x 25.5 cm x 25 cm, and it weighs 2 kg.

IV.3. DS200L

IV.3.A. THE AC/DC POWER SUPPLY - SPS200

For small capacity DS200L systems, SPS200 power supplies are used. Details regarding those power supplies have been explained in previous chapters.

SPS248 power supplies are also used in the DS200L systems. Details regarding those power supplies have been explained in previous chapters.

Page 57

DS Series PBX Technical Reference And Installation Guide

IV.3.C. THE EXTERNAL POWER BLOCK

In case of large capacity DS200L systems require high capacity battery groups, external power supplies can be used instead of SPS200 power supplies.

For proper power regime, in addition to external power supplies the capacities of the batteries must be selected appropriately for the system capacity.

External Power Block feeds DCC block, power inverter and the SPS248 power supplies which are at the TW200 towers by -48V. Cabling is to be made from external power supply to each tower and to other units.

IV.3.C.1. THE POWER INVERTER

For small capacity systems, in case system is fed by SPS200 power supplies, PCU Block and network switch can get the required 220V AC voltage from the electricity network. In this case, there will be no need for power inverter.

For large capacity systems, system gets -48V voltage from the external power supply, -48V coming from External power block is converted to 220V AC and transmitted to PCU200 block, redundant PCU200 block and network switch. Power inverters are located in the 19” cabinet. Optionally, redundant power inverter can be installed to the system. At the systems which have redundant power inverter, in case any problem with any of the power inverter occurs, the redundant power inverter is put into operation. Thus, PCU200 blocks and network switch get the 220V AC input from the redundant one and keep operating without any problem.

Inverter and redundant one for DS200L system are shown below.

V.1.A. CPU200 MODULE

Definition:

The CPU200 Central Processing Module is the brain of the system. It includes microprocessor and memory circuits on it. CPU200 is present only in the main rack and it is plugged into the card slot that is fourth from the left.

Page 59

DS Series PBX Technical Reference And Installation Guide

Technical Information:

The CPU200 module consists of two different cards. The card at the bottom has the address and data buses that carry the required signals to the main rack of the exchange, whereas the upper one contains the entire memory elements and the Power PC (PPC) 850 processor circuits. The PPC is a RISC based processor of 80 MIPS processing power.

The CPU200 Module is plugged into the corresponding 64-pin connector on the BPL200MAIN backplane and it is fixed to the upper and lower front sections of the metal rack through the fixing latches that are on the front card cover.

CPU200 contains memory elements such as 32 MB FLASH ROM, 256 MB DRAM and EEPROM, as well as the ICP (Intra-rack Communication Protocol). In addition to that, CPU200 is responsible for generation of system clock pulses.

CPU200 generates address and data signals, which are required for the UTIL200 and EX200 Modules. It transmits those signals to BPL200-MAIN over a 64-pin connector, and to the BPL200-AUX backplane over the two 34-pin connectors that provide the BPL200-MAIN BPL200-AUX connection, and to the second cabinet over a 34-pin connector that is employed for that transmission when required.

Data signals which are essential to the entire accessories are generated on CPU200 and then they are transmitted to DS200 CPUKON over DS200 CPU-FC.

Operational Information:

A LED is situated on the front panel of CPU200. This LED continuously blinks during normal operation. On the other hand, it remains on during a reset or parameter transfer. By this way, the status of the system can be monitored through this LED.

The CPU200 card has two Ethernet connectors. One is for a PC connection for maintenance, programming, etc and for IP extensions. The other one is for IP trunks.

* CPU200 MUST NOT BE REMOVED WHILE THE SYSTEM IS OPERATING.

Dimensions of CPU200 are 20 cm. x 22.5 cm. and it weighs 0.3 kg.

Page 60

V.1.B. REDUNDANT CPU200 MODULE

Definition:

The redundant CPU200 module has structurally no difference compared to the CPU200 module; it is just an optional module that could be employed for backing up the CPU200 card in the system against possible problems.

Technical Information:

In the systems with the redundant CPU200 module, two CPU200 cards are installed in the main rack.

Thanks to an intelligent circuit on the BPL200-MAIN backplane, the system actually begins using one of those CPU200s. In the mean time, the same intelligent circuit continuously controls the actions of the active CPU200. On the other hand, in the event that any problem with the CPU200 card occurs, which is actively being used, that intelligent circuit automatically puts the redundant CPU200 card into operation and takes the problematic card out of use. This operation takes place so fast that users would not even realize it.

Operational Information:

LED of the redundant CPU200 card continuously blinks, however its frequency is higher than that of the LED corresponding to the normal CPU200 card. By this way, one can know which one of the modules in the system is actually in use and which one is on standby.

Dimensions of CPU200 are

20 cm. x 22.5 cm. and it weighs 0.3 kg.

V.1.C. DS200 CPUKON CARD:

Definition:

The DS200 CPUKON CPU Connection Card constitutes the interface between the system and the accessories. There are connectors on it in order to connect the accessories to the system. DS200 CPUKON is present only in the main rack.

Technical Information:

The DS200 CPUKON CPU Connection Card is located in the main rack, without being connected to the BPL200-MAIN backplane. The card is fixed to the front lower and upper parts of the metal rack by the fixing latches on front card cover. It is connected to the CPU200 card over a 26-pin flat cable (DS200 CPU-FC.)

Apart from being a bridge between the external peripherals and the system, a major job of the CPUKON card is to preserve the license information of the system.

All the license information related to the system are preserved on a serial security plug – called SGB – which resides on the card. For all the units to be licensed, the license keys obtained from Karel are entered to the system and kept on the plug encrypted. If somehow the SGB is removed from the CPUKON card, all the licenses become disabled.

Appearance of the DS200 CPUKON card and the connectors on it are shown in the illustration below.

V.2. DS200S & DS200M

V.2.A. CPU200S MODULE

Definition:

The CPU200S Central Processing Module is the brain of the system, and it is a module used commonly in the DS200S and DS200M exchanges.

It includes microprocessor and memory circuits on it. It is plugged into the second CPU200S card slot from the left.

Technical Information:

The CPU200S module consists of two different cards. The card at the bottom has the buses that carry the required signals to the main rack of the exchange, whereas the upper one contains the entire memory elements and the Power PC (PPC) 850 processor circuits. The PPC is a RISC based processor of 80 MIPS processing power.

The CPU200S Module is plugged into the corresponding 64-pin connector on the BPL200S/M backplane and it is fixed to the upper and lower front sections of the metal rack through the fixing latches that are on the front card cover.

CPU200S contains memory elements such as FLASH ROM, DRAM and EEPROM, and the switching matrix, as well as the ICP (Intra-rack Communication Protocol). In addition to that, CPU200S is responsible for generation of system clock pulses.

Page 66

CPU200S generates address and data signals, which are required for the EX200 Modules. It transmits those signals to the BPL200S/M backplane over a 64-pin connector.

Data signals which are essential to all accessories are generated on CPU200S and then they are transmitted to DS200S CPUKON over DS200 CPU-FC.

Operational Information:

A LED is located on the front panel of CPU200S. This LED continuously blinks during normal operation. On the other hand, it remains on during a reset or parameter transfer. By this way, the status of the system can be monitored through this LED.

The CPU200S card has two Ethernet connectors. One is for a PC connection for maintenance, programming, etc and for IP extensions. The other one is for IP trunks.

* CPU200S MUST NOT BE REMOVED WHILE THE SYSTEM IS OPERATING.

Dimensions of CPU200S are 20 cm. x 22.5 cm. and it weighs 0.3 kg

V.2.B. DS200S CPUKON CARD:

Definition:

V.3. DS200L

V.3.A. THE PCU200 BLOCK

V.3.A.1. GENERAL INFORMATION

PCU200 is a processor structure that has been based on a 19” PC, which controls all functions of the exchange.

The PC that functions as the PCU200 is 19” in width, 2U in height and 80 cm in depth. It is placed in a 19” cabinet.

The master software of the exchange runs under the Linux Suse 11.0 on the PCU200 computer. The minimum requirements of a DS200L PCU block:

• Pentium IV 2.4 GHz. processor

• 60 GB hard disc

• 1 GB RAM

The master software runs under LINUX in real time and performs its functions by means of a file system. Using this file system, the entire exchange parameters, statistical data, call records, alarm information, etc. are stored in separate files on hard disc.

Figure shows the PCU200 and the redundant PCU200 in a 19” cabinet.

V.3.A.2. COMMUNICATION

PCU200 communicates with the other units within the exchange over the TCP/IP protocol. PCU200 is the unit that initiates intra-exchange communication.

PCU200 controls all the communications between all the exchange units. The communication information, namely IP addresses and TCP ports of the DCC and TW200 units are entered in a table in the PCU200.

Thanks to that structure, both of the blocks that carry out TDM and IP switching can be controlled by the same center. Besides, PCU200, which provides communication through the ethernet structure, has completely been isolated from exterior factors. That fact is extremely essential considering that the system security is thus increased.

Page 68

V.3.A.3. REDUNDANCY

It is possible to backup the PCU200 block upon wish, with another PC that is a one-to-one copy of it. The redundant and functional PCU200 blocks are in connection with each other through ethernet ports and in case of any malfunction that occurs in the functional PCU200 block, the redundant PCU200 directly becomes functional.

V.3.B. THE CC MODULE

The CC module, instead of the CPU module, is used in the DS200L system.

The function of the CC200 module is to provide communication between the PCU200 block and the racks. The CC200 card and the CPUKON card work in coordination again.

CC card has:

■ 1 Ethernet port

■ 16 MB Flash Memory

■ 64 MB RAM

■ Linux operating system

NOTE: No redundant CC200 is used in the TW200 towers. Since the PCU200 block fulfills the tasks of CPU200 card, redundancy of the PCU200 block is available in the DS200L exchange.

VI. THE SWITCHING MODULE

VI.1. DS200-UTIL200

Definition:

The UTIL200 Utility Module is the auxiliary processor card, which is present in every rack, and which performs switching, tone generation and receiving operations within its own rack, as well as among other racks.

Page 71

DS Series PBX Technical Reference And Installation Guide

Technical Information:

UTIL200 can be placed in the card slot, which has been specially designed for it within the rack. The module is connected to the appropriate 64-pin connector on BPL200-MAIN or BPL200-AUX and then it is fixed to the front lower and upper parts on the metal rack through the fixing latches on the front card cover.

There is a DSP module on UTIL200 that carries out the entire tone generation and receiving operations. UTIL200 has the TDM/PCM switching circuits that maintain the entire inter-rack switching. Moreover, intra-rack switching is also carried out by the UTIL200 module of each individual rack in coordination with the CPU200 control.

In each UTIL200 module, there are 16 PCM channels for inter-rack switching and 14 PCM channels for intra-rack switching. By this way, a two-rack system operates completely without blocking. In addition to that, sufficient resources are available in each UTIL200 Module for the operation channels listed below:

Number of DTMF receivers: 32

Number of DTMF generators: 8

Number of R1 receivers: 32

Number of R1 generators: 16

Number of Tone receivers: 12

Number of Tone generators: 12

Resources of the entire UTIL200 cards, which have been listed above are combined in a common pool in systems with several racks, and by this way, the entire resources become available to the entire system in general.

The UTIL200 card also includes a special switching circuit for the conferencing feature, which is supported for up to 32 participants. Thanks to this circuit, several multiple conferences with 32 participants in total can be carried out, as well as a single conference with 32 participants. Likewise, in addition to the multiple conferencing feature, resources for 8 conferences with 3 participants are also available on the UTIL200 card.

* UTIL200 MUST NOT BE REMOVED WHILE THE SYSTEM IS OPERATING.

Operational Information:

There are two LEDs on the front panel of the UTIL200 module. The upper one signifies that the card is operating and the lower one displays the status of communication with the CPU. During normal operation, the first LED lights continuously, whereas the other blinks.

Dimensions of UTIL200 are 20 cm. x 22.5 cm., and it weighs 0.3 kg.

VI.2. DS200S & DS200M

The UTIL200 card is not used in the DS200S and DS200M systems. The functions of that card are fulfilled by circuits, which are present on the CPU200S card and with the switching facility, the system allows a three party conference as well.

Page 72

VI.3. DS200L

The main TDM switching matrix of the DS200L system is the DCC block. The switching between the towers is handled by the DCC block. However, the UTIL200 card used in DS200 systems, is also used in each rack of DS200L systems to handle the switching within the tower. Additionally, the module, which is named the Utility 4E1 card is mounted on the UTIL200 card to provide the communication between the towers and the DCC block.

For the IP switching an Ethernet switch is used.

VI.3.A. THE DCC (DIGITAL CROSS CONNECT) BLOCK

The DCC Block is the switching matrix that fulfills the main switching function for the exchange.

DCC block has a structure that includes the main switching controller card ( DCC Utility ), 14 of 8E1 Interface card slots and a power regulation card ( DCC Power In ). Due to its standard 19” structure, it is placed in the same 19” cabinet with the main processor block PCU200.

A DCC block consists of the units below:

• DCC Chassis

• DCC Backplane

• DCC Utility Card

• DCC 8E1 Interface Card

• DCC Power In Card

SLOT NO:

13 12 11 10 9 8 7 CP2 CP1 6 5 4 3 2 1 0

Page 73

DS Series PBX Technical Reference And Installation Guide

VI.3.A.1. THE DCC CHASSIS

The DCC chassis is a 19”, 6U-high box, which has been formed of an aluminum cage structure and which mechanically places the entire cards in contact.

It has slots for 17 cards inside, which is composed of plastic rails that are at the top and bottom of the slot.

Lower and upper covers have been designed to allow air circulation in the DCC block. The air vents on those covers have been designed according to EMC (electromagnetic compatibility) and EMI (electromagnetic interference) rules.

The aluminum card covers has a special lock mechanism. On each of the lower and upper sections of the card covers, there is a screw and special-purpose plastic holders. Those holders allows cards to be plugged in firmly when they are pushed into the chassis, whereas they facilitate removing cards and allows them to be pulled out without jerking. Cards are completely fixed in their positions in the chassis by tightening the screws that are on the lower and upper sections of the card cover.

Each card cover has connector spaces that allow the card to be connected to other units. By this way, the entire cabling of the DCC block, which has been placed in the 19” cabinet, can easily be done through the front face.

The chassis has no front cover. Each card that is to be placed in the chassis has an aluminum card cover on one edge, thus, those card covers form a front cover when the cards are plugged in side by side. Lighted indicators on the front face supply various pieces of information to technical personnel.

VI.3.A.2. THE DCC BACKPLANE

Communication of the entire electronic units in the DCC block is made over the DCC backplane. The DCC backplane is the card that constitutes the electronic framework of the DCC block. The DCC backplane transfers all signals used by DCC cards to pertinent card slots and it distributes the power coming from the DCC Power In card to all card slots. The DCC backplane is the card that forms the electronic skeleton of the DCC block.

There are 2 special slots for the DCC Utility card and one special slot for the DCC Power In card on the backplane, as well as 14 slots for DCC 8E1 Interface cards.

VI.3.A.3. THE DCC POWER IN CARD

Definition:

The DCC Power In card regulates the -48V DC feed voltage it receives from the power block of the DS200L system and transfers it to the backplane.

The Power Control Card controls the -48V DC voltage fed to the DCC unit and minimizes surges in voltage with fuses and regulators on it. The card also generates the reference signal for the backplane, which is 1.5V DC.

Page 74

Technical Information:

Each DCC unit has minimum one Power In card. The card definitely must not be removed from its slot while the system is ON. The DCC Power In card is plugged in the rightmost slot. If redundant of this card is available, redundant card should be installed into the leftside (slot number 0) of the DCC Power In card. Normally, this slot is used for DCC 8E1 Interface cards. When redundant DCC Power In card is installed, number of DCC 8E1 Interface cards to be installed is decreased by 1 and equal to 13. When redundant DCC Power In card is installed into the system, system will go on operating without any problem in case any problem occurs at master DCC Power In Card.

Operational Information:

The LEDs signifying +3V3 and +1V5 statuses are supposed to be continuously ON during the normal operation of the system, whereas all the other LEDs are supposed to be OFF. In case the LED statuses are different from what have been specified here, the system should be checked.

Page 75

DS Series PBX Technical Reference And Installation Guide

VI.3.A.4. THE DCC UTILITY CARD

Definition:

The DCC Utility card is the main unit, which controls the entire DCC functions and which includes the switching matrix.

The DCC Utility card consists of the Utility motherboard and the PPC CPU card which has been attached to the motherboard with two connectors that are on the motherboard. The main processor of the DCC Utility card is the Power PC CPU card.

Technical Information:

Main components of the PPC CPU card are the PPC central processor microchip, a nonvolatile memory (FLASH) of 8MB, a volatile memory (SDRAM) of 32 MB and two 120-pin motherboard connectors (X1 and X2).

Since the DCC unit has a structure with multiple processors, several different pieces of software are used in the system. While majority of the pieces of software run on the CPU card that is on the Utility card, the others run on the slave cards (8E1 cards), which are installed in the 14 slots that are on the DCC backplane.

A single Utility card suffices for DCC operation. However, a redundant one may be made available when needed , two Utility cards can be installed in the DCC block. Both cards are identical in hardware. In case of a malfunction in the functional DCC Utility card, the DCC automatically shifts to the redundant Utility card. During that transition, no system pause or data loss occurs.

The DCC Utility card and the redundant DCC Utility card, if available, are supposed to be installed in the slots in the middle, which are labeled CP1 and CP2 on the DCC backplane. Master DCC Utility card is installed into the CP1 slot and redundant DCC Utility card is installed into the CP2 slot.

An RS232 input, a 100 Mbit Ethernet input, a 10 MB Ethernet input and some LEDs are available on the DCC Utility card. Functions of those LEDs will be explained later in the document.

The DCC Utility card receives the 48V DC feed voltage from the backplane and generates the 3.3V DC signal it needs. By this way, the power signals within the DCC block have been isolated from each other, so that defective units are prevented from adversely affecting other units.

The card has embedded self-test feature. Thanks to that feature, the DCC Utility card is capable of testing itself while it is applying BERT ( Bit Error Rate Test) to the E1 channels within DCC. By this way, any problem that might occur in the future is easily detected in advance and necessary precautions are taken before system performance deteriorates.

The DCC Utility card can be synchronized with the External clock signal received through 8E1 lines, thanks to the PLL block on it. DCC can transmit the clock signal it receives by that way to towers of the DS200L system, so that the entire system operates in synchronization with the External clock signal. The DCC Utility card also has anti-jitter circuits in order to minimize adverse factors that might be present in the External clock signal, like noise and jitter.

The DCC Utility card fulfills the tone generation function in order to transmit the tones to network during direct E1 connections with the External network. Thanks to DSPs on it, it generates tones like the alerting tone & hold tone and transmits them over E1 lines when needed.

Page 76

Operational Information:

The LEDs on the DCC Utility card and their functions have been explained below:

POWER:

This LED is supposed to be continuously ON. If it flashes, then the DCC block must

be turned OFF and then back ON after 15-20 seconds.

DSP-A, DSP-B, DSP-C, DSP-D:

These LEDs signify that the DSP unit is operational. They

are supposed to be blinking periodically.

10 RX, 10 TX / 100RX, 100TX:

These are supposed to be flashing during data transmission

or reception over local area network (LAN).

CPU:

It is supposed to blink periodically.

M/S (Master/Slave): This LED is supposed to be continuously ON, if the master DCC Utility card is functional in the DCC Block.

LOCK:

DCC This LED is supposed to be blinking periodically, if DCC is using external clock.

If does not blink periodically, then that signifies there is a problem with the external clock signal.

HOLD:

This LED is supposed to be continuously ON, if DCC is using its own clock signal.

Page 77

DS Series PBX Technical Reference And Installation Guide

VI.3.A.5. THE DCC 8E1 INTERFACE CARD

Definition:

The DCC 8E1 Interface card has 8 E1 ports as its name already indicates, and it can be installed in the 14 general-purpose slots within DCC. 8E1 cards have been numbered starting with the rightmost slot in the DCC Block. The rightmost slot (leftside slot of the DCC Power In Card) has been reserved for the 8E1 card number 0, and the leftmost one for the 8E1 card number 13 in the DCC block.

Technical Information:

The DCC 8E1 Interface cards communicate with the DCC Utility card over the HDLC protocol.

The DCC 8E1 Interface card receives the 48 VDC feed voltage from the backplane and generates the 3.3 VDC signal it needs. By this way, the power signals within the DCC block have been isolated from each other, so that defective units are prevented from adversely affecting other units.

The DCC 8E1 Interface card has embedded self-test feature. The DCC Utility card is capable of applying BERT test to the E1 channels within DCC. By this way, any problem that might occur in the future is easily detected in advance and necessary precautions are taken before system performance deteriorates.

The DCC E1 lines constitute the main frame for voice transmission system of the exchange. Those lines can be used to provide transmission paths for speech channels between DCC and TW200 towers.

The E1 lines connected to TW200 towers are called “switching E1 lines ”.

The E1 lines extending to TW200 towers are connected to the Utility 4E1 cards that are in the towers. On doing that, it is obligatory to connect at least one E1 line to each tower. Each E1 line provides 31 speech channels to a tower. It is sufficient to increase number of E1 connections to towers in order to increase number of speech channels. In case where several E1 channels are connected to the TW200 4E1 card, distribution of speech channels to those E1 lines is arranged by the system automatically.

Page 78

VI.3.A.6. THE SWITCHING STRUCTURE OF DCC

Intra-rack and inter-rack switching in the DS200L system are conducted over the UTIL200 card, whereas inter-tower switching (switching between towers) is conducted over DCC.

The DCC block has a 4096 x 4096 switching matrix. By this way, 8192 channels in the DS200L exchange can be simultaneously used for conversations.

The switching matrix on the DCC block is distributed to the TW200 towers over E1 lines in DCC. Thanks to the isolated E1 structure, trouble-free connections can be established even with the distant TW200 towers.

Due to its structure, DCC is continuously in communication with both the TW200 towers and the PCU block. It communicates with the towers over E1 connection, whereas it communicates with the PCU block over TCP/IP.

Number of 8E1 cards to be installed depends on the capacity of the exchange to be used. At most 14 DCC 8E1 Interface cards can be installed in the DCC block. By this way, the capacity may vary between 8 E1 and 112 E1 lines. If the capacity provided by only a single DCC is not enough, then it may be expanded by including a second DCC in the system, so that both the switching capacity is increased from 4096 x 4096 to 8192 x 8192, and number of E1 lines is increased up to 224.

The E1 lines in the DCC are used to establish speech channel connection with the TW200 towers. 1 to 12 E1 lines can be connected to each tower, depending on capacity requirements. (Each E1 has 31 channels.) By this way, it is possible to provide 31 to 372 speech channels for 672 extensions. Number of the E1 lines to be allocated to towers is one of the most important parameters that determine capacity of the exchange.

Page 79

DS Series PBX Technical Reference And Installation Guide

VI.3.B. THE NETWORK SWITCH

Communication and information exchange in the DS200L systems are carried out over the IP network.

Function of the network switch is to provide the TCP/IP switching of the system blocks and to coordinate the IP communication.

The network switch is located in the 19” cabinet.

Using a programmable network switch (which has port mirroring feature) will be useful for managing the network.

The Ethernet cables that are supposed to be connected to the switch are as follows:

• The ethernet cables coming from the CC cards in TW200 towers

• The ethernet cables coming from the PCU200 Block and the redundant PCU200

Block

• The ethernet cable of the maintenance computer

• The ethernet cable coming from the DCC Block

• The ethernet cable coming from the External Power Supply (if exists)

Figure below shows the 24-port network switch, to which the cables specified above are to be connected.

NOTE: IP addresses of the devices specified above must be so adjusted that they are in the same local area network.

VI.3.C. EX200 UTILITY 4E1 CARD

There are 4 E1 ports on this card. At least 1, at most 12 E1 connections can be made per tower. The E1 ports that are on the 4E1 cards are connected directly to the 8E1 cards that are in the DCC Block. Speech channels between the TW200 towers and the DCC block are connected through the E1 channels of the towers.

Not every UTIL200 module has to have a Utility 4E1 card on it in DS200L systems. Number of the Utility 4E1 cards is determined according to the need for E1 ports. Nevertheless, at least one Utility 4E1 card must be present in every tower (A TW200 tower consists of maximum 3 racks).

* Those cards need two slots.

Page 82

The EX200 modules are plugged into the general-purpose slots in the racks. In other words, the modules are connected to the appropriate 64-pin connector on the backplanes and then they are fixed to the front lower and upper parts on the metal rack through the fixing latches on the front card cover.

Exchanges of the DS200 series have a “factory default” numbering plan starting from 1110 for extensions and lines. After all of the modules have been installed and the system has been powered, the system automatically checks the entire modules and detects them, and then it automatically arranges the numbering plan accordingly.

There are 16 numbers that have been assigned to each slot in the numbering plan. Therefore:

• When, for example, an EX200 (8+/0) module is installed in one of the slots, the first 8

numbers are assigned to lines, whereas the other 8 numbers remain unused.

• When an EX200 (4E&M/0) module is installed in one of the slots, the first 4 numbers are

assigned to E&M lines, whereas the other 12 numbers remain unused.

• When an EX200 (1E1/0) module is installed in one of the slots, in addition to the entire 16

numbers in that slot, the first 14 numbers of the next slot are also assigned to the channels of the related line. The last two numbers of the next slot remain unused.

VII.1. CONNECTION CARDS AND CABLES

Definition:

CON2, CON3, CON4, CON5, CON6 and CON7 connection cards constitute the connection point between the extension phones / CO lines and extension / line circuits of the system. In fact, the cables CBL-16 and CBL-8, which are used alongside those connection cards, have been developed in order to provide facility for connection operations.

Technical Information:

The CON cards include some common high voltage protection components in order to protect the circuits on the EX200B card against effects of high voltage that could be present in the environment.

There are 4 RJ45 female connectors on the CON2, CON4, CON5, CON6 and CON7 cards. The MDF cable with 16 pairs, namely CBL-16, has been designed specifically for those cards. The male RJ45’s that are at one end of the CBL-16 cable are attached to the corresponding female connectors that are on the CON card. The cable lengths have been adjusted so as to facilitate installation. The structure of the card and cabling have been shown in the photo and the illustration below.

VII.2. EX200 EXPANSION MODULES

Definition:

The EX200 is a module that consists of an extension or line card (EX200B), the appropriate connection card (the CON card) and the cable (CBL-16 or CBL-8.)

The figure below illustrates the structure of the EX200B Expansion Module Card.

2. CON Card Connectors 5. Card Fixing Click

3. CON Card Fixing Clicks 6. Card Removing Latch

Technical Information:

All EX200B cards include some circuits such as PCM frame signal buffers, micro controller and ICC (Intra-rack Communication Controller).

Each EX200B card also has over-current protection circuits against currents running on it. For example: Since the analog extension module makes use of the –48 VDC, -5VDC and +5VDC feeds of the system, there are three separate over-current protection circuits on it.

ICC is also an essential part of EX200B cards. Distributed CPU structure is maintained by the Intra-rack Communication Protocol (ICP), which is an ISDN-like protocol. ICC is the communication structure that actualizes the communication between the main CPU of the system and the modules.

Page 86

There are 14 PCM channels for each rack (7 PCMs for receiving, 7 PCMs for transmitting 32 frames for each PCM.) Hence, each general-purpose slot uses 16 PCM frame pairs of a PCM channel pair. These 16 PCM frame pairs have been connected to each slot on the backplane via special paths, so that a static structure has been formed.

Since there are 16 PCM frame pairs in each slot, each extension or line module can use at most 16 PCM frame pairs in a single slot. As explained in the related sections later in the guide, every other module, except the E1-based modules such as EX200 (1E1/0), make use of 16 PCM frame pairs; therefore, they can be installed in any vacant slot. (Note that an extension card should be installed in the first slot, because the first number of the first expansion slot has been assigned to the operator, through which programming is to be done.)

* IN CASE IT IS REQUIRED, THE EX200 EXPANSION MODULES CAN BE

REMOVED FROM THE SYSTEM THROUGH PROGRAMMING WHILE THE

SYSTEM IS STILL RUNNING.

Dimensions of DS200 EX200B are 20 cm. x 22.5 cm., and it weighs 0.3 kg.

Details about all EX200 Extension / Line Module types are as follows.

VII.3.A. EX200 (0/16R) ANALOG EXTENSION MODULE

In addition to the common circuits explained above, there are 16 analog extension circuits (SLIC) on the EX200B (0/16R) card, which are identical.

Each SLIC includes a CODEC for analog to digital and digital to analog conversions and a transformer, as well as the standard circuits such as – 48 VDC feed, handset status detection, 2-4 / 4-2 wire conversion.

Those extensions possess some extra features in addition to the standard extension features:

• 12 or 16 KHz pulse price signal generation

• Polarity reversal generation

• Caller ID generation

• Automatic test

The connections to the EX200B (0/16R) card are made over the CON5 line connection card.

VII.3.B. EX200 (0/16C) ANALOG EXTENSION MODULE

In addition to the common circuits explained above, there are 16 identical analog extension circuits (SLIC) on the EX200B (0/16C) card, which are capable of carrying Caller ID information.

Page 87

DS Series PBX Technical Reference And Installation Guide

Besides the standard circuits such as – 48 VDC feed, handset status detection, 2-4 / 4-2 wire conversion, each SLIC also includes a CODEC for analog to digital and digital to analog conversions and a transformer.

Cadences of the tones and the ringers of telephones are controlled by the card’s own micro controller.

The Caller ID information can be programmed in DTMF or FSK format on extension basis.

Connections to the EX200B (0/16C) card are made over the CON7 line connection card.

VII.3.C. EX200 (8+/0) ANALOG EXPANDABLE LINE MODULE WITH CALLER ID

In addition to the common circuits mentioned above, there are 8 line circuits on the EX200B (8+/0) card that are identical.

Each group of four lines includes standard circuits, namely a DC current driver, a ringer detector, a 2-4 / 4-2 wire conversion circuit, a pulse price signal filter, a polarity reversal detection circuit, and a CODEC that fulfills analog to digital and digital to analog conversions, as well as a transformer for each line. Thanks to the structure of the CODECs on the module, transmission and reception levels for the transmitted voice can be adjusted separately in 8 levels.

The most important features of this card are the possibility of capacity expansion and Caller ID.

The card has two extra connectors to install one more card. One of the following cards can be plugged into those connectors:

a) A card with 8 analog lines > By this way, the total capacity of the card becomes 16

analog lines.

b) The FSK Caller ID Card > By this way, the 8 lines can decode the Caller ID information,

which is in FSK format.

c) The DTMF Caller ID Card > By this way, the 8 lines can decode the Caller ID information,

which is in DTMF format.

Connections to the EX200B (8+/0) card are made over the CON6 line connection card.

VII.3.D. EX200 (0/8S0) ISDN BRI EXTENSION MODULE

In addition to the common circuits mentioned above, there are 8 identical ISDN BRI extension circuits on the EX200B (0/8S0) card.

Since ISDN is a digital protocol, there is no need for an extra circuit; the standard ISDN BRI driver, which each extension has, is sufficient.

Connections to the EX200B (0/8S0)

card are made over the CON2 line connection card.

Page 88

VII.3.E. EX200 (1E1/0) PRI /R2 /QSIG SWITCHABLE E1 LINE MODULE

The EX200 (1E1/0) module does not have a line connection card however it has an MDF cable with an RJ45-type male connector at the end. In addition to the common circuits mentioned above, there is only a single E1 line (with 30 channels) on the module. Connection to that line is fulfilled directly through the RJ45 connector, which is at the end of the MDF cable.

Since PRI, R2 and QSIG are digital protocols, no extra circuit is needed; however, the protocols are embedded on the microcontroller of the card and the selection among them is made by programming (no hardware modification required). If R2 is selected the DSP module present on the card generates or detects the MFC signals, which are specific to the R2 protocol, simultaneously for 30 channels.

Since E1 has 30 speech channels, the 16 PCM frames in each slot do not suffice for the 30 channels of a line. Therefore, the EX200B (1E1/0) card should be installed in a slot with an even number (the leftmost general-purpose slot has been numbered as 0) and the next slot with an odd number should be left vacant. By this way, the EX200B (1E1/0) card can make use of the 32 PCM frames in total, which belong to both of the slots.

In addition to the RJ45 socket, there is a 9-pin, D-type connector on the EX200B (1E1/0) card, which is for the connection to the E1 line.

VII.3.F. EX200 (1CAS3B/0) CAS3B DIGITAL LINE MODULE

The EX200 (1CAS3B/0) module has no line connection card, but it has an MDF cable with an RJ45-type male connector at the end. In addition to the circuits that are common with the other expansion cards, there are circuit components on the module that provides the interface with the 30 digital lines. Connection to the CAS3B line with 30 channels is fulfilled directly through the RJ45 connector that is at the end of the MDF cable.

The EX200 (1CAS3B/0) module has an E1-based structure. It provides high speed and quality in network applications. Thanks to the DSP module present on it, it generates or detects the MFC signals, which is specific to the R1 protocol, simultaneously for 30 channels.

Since the EX200 (1CAS3B/0) module can be connected to 30 separate channels, the 16 PCM frames in each slot do not suffice. Considering this fact, the EX200B (1CAS3B/0) card should be installed in a slot with an even number (the leftmost general-purpose slot has been numbered as 0) and the next slot with an odd number should be left vacant. By this way, the EX200B (1CAS3B/0) card can make use of the 32 PCM frames in total, which belong to both of the slots.

VII.3.G. EX200 (0/8KoU) DIGITAL EXTENSION MODULE

In addition to the common circuits mentioned above, there are 8 identical special digital extension circuits on the EX200B (0/8KoU) card.

Since the card has a digital protocol due to its structure, no extra circuit is needed; however, each extension has an individual digital driver.

Connections to the EX200B (0/8KoU)

card are made over the CON3 line connection card

VII.3.H. EX200 (0/16KoU) DIGITAL EXTENSION MODULE

In addition to the common circuits mentioned above, there are 16 identical special digital extension interface circuits on the EX200B (0/16KoU) card.

Since the card has a digital protocol due to its structure, no extra circuit is needed; however, each extension has an individual digital driver.

Connections to the EX200B (0/16KoU) card are made over the CON2 line connection card.

VII.3.I. EX200 (8 T0/0) ISDN BRI LINE MODULE

In addition to the common circuits explained above, there are 8 identical ISDN BRI line circuits on the EX200B (8T0/0) card.

Since ISDN is a digital protocol, no extra circuit is needed; but each line has a standard ISDN BRI driver.

Connections to the EX200B (8T0/0)

card are made over the CON2 line connection card.

VII.3.J. EX200 (0/8LB) LOCAL BATTERY EXTENSION MODULE

In addition to the common circuits specified above, there are 8 identical LB line circuits on the EX200 (0/8LB) card.

The EX200 (0/8LB) module has been designed in order to provide the interface required for the connection of field telephones to an exchange of the DS200 series. Thanks to that interface, eight local battery telephones can be connected to the exchange. All of the eight telephones can be forwarded to a single telephone on the exchange side, as well as each local battery telephone can individually be forwarded to a specific telephone directly, which has been assigned to it.

Connection to field telephones shall be two-wire. Since that type of telephones are not fed with DC voltage and since the EX200 (0/8LB) module provides the user with the possibility of changing incoming-outgoing voice gain, cables extending to long distances can be installed.

Page 90

The EX200 (0/8LB) module allows two methods for gain control. First of them is to determine a permanent gain level for a specific line at the beginning and to set it on the module. The second method, on the other hand, is to set the gain level temporarily by using hook flash and keypad during each conversation. This operation can be carried out by the extension with hook flash authorization on the exchange side only, for a local battery telephone does not possess hook flash function.

The EX200 (0/8LB) Module, like E&M module, can also be used for inter-exchange connections.

There is a transformer on the EX200B (0/8LB) card in order to isolate the speech circuit, and a varistor against the case that a ring is received while the line is active. The ringer signal coming over from the power supply is directly transferred to the extension through relay protection.

Connections to the EX200B (0/8LB) card are made over the CON3 line connection card.

VII.3.K. EX200 (4 VoIP) VOICE OVER IP MODULE

In addition to the common circuits explained above, there are 4 VoIP channels on the EX200B (4VoIP) card. Those VoIP channels work in compliance with the H.323 or SIP protocol.

When the module is utilized as an external line, institutions/corporations possessing several DS200 series exchanges can establish the infrastructure that enables phone calls over IP lines by connecting their exchanges to each other over lines of IP network.

In this type application, “Frame Relay” or “Leased Line” type of lines are usually employed for data transfer among remote offices. Making phone calls over these very lines as well would provide advantage towards cutting communication expenses of a corporation.

The EX200 (4VoIP) card works as a gateway that establishes connection between the exchange and the IP network. Thanks to the EX200 (4VoIP) card, direct voice communication can be established without the need for interfaces like FXO, FXS for routers, which are present in the IP networks.

Since the VoIP applications are software-based ones, basic functions are fulfilled by the DSP on the card.

By way of its intelligent and capable software the VoIP card supports, G711 and G729 codecs, echo canceller, jitter buffer and etc.

Connection to the EX200B (4VoIP) card is made over the RJ45 Ethernet connection on the front face of the card.

VII.3.T. EX200 (MGW1) MEDIA GATEWAY MODULE

A Media Gateway means the connection between the IP ports of the system and the TDM (analog and digital) ports of the system or conversion from TDM to IP and from IP to TDM. When an analog extension calls an IP extension or vice verse, the speech is bridged by the media gateway channels.

The EX200 (MGW1) module supports 16 channels however, the channels to be used are set by a license. MGW1 module has echo canceller, jitter buffer control, and similar QoS services and G711 and G729 codecs.

As explained above the MGW1 is designed to carry audio to the destination via RTP packages addressed by the system software.

The hardware structure of the EX200 (MGW1) module is exactly the same as the EX200 (16VoIP/0) module. However, the software is different.

Connection to the EX200 (MGW1) card is made over the RJ45 Ethernet connection on the front face of the card.

VII.3.U. EX200 (MGW2) ADVANCED MEDIA GATEWAY MODULE

VIII. THE AUTO ATTENDANT AND VOICE MAIL

MODULE – EVM200L

Definition:

EVM200L is an integrated Auto Attendant and Voice Mail module for DS200 series exchanges. Since it has been designed as an interface module, it can be installed in any general-purpose slot of the system. At most 8 EVM200L modules can be employed in a system of the DS200 series.

EVM200L has three main functions:

1) Automatic Call Distribution (ACD-Auto Attendant) (Message announcement in two languages is possible.),

2) System Messages (Message announcement in two languages is optionally possible.),

3) Voice Mail Service

Technical Information:

The Auto Attendant allows the operator to work more efficiently, especially during busy hour traffic, by guiding external calling parties through pre-recorded messages.

The system messages, on the other hand, inform extensions (users) through pre-recorded messages about statuses of their telephones. By this way, extensions could always know about features that are already active at their telephones.

Thanks to the voice mail service, extensions can have private message boxes to receive or leave messages to each other.

In order to actualize all those functions, EVM200L has been equipped with memory elements in different types.

FLASH ROM memories are employed as non-volatile memory elements for ACD and the system messages, so that those messages are not cleared even when the system power is cut off. The on-board memory capacity is 4 minutes for ACD messages and 2 minutes for the system messages.

There are two expansion slots for optional EVM-FL cards in every EVM200L module. An EVM-FL card, which has been installed in one of these slots, can be employed upon wish as a two-minute FLASH ROM memory for ACD messages, or it can increase the system message memory capacity by 2 minutes upon wish, in order to enable the use of a second language for the system messages. However, the second EVM-FL card can be used to increase the ACD message capacity only.

DRAM memories are used as volatile memory elements for the voice mail service. Messages of that type are not saved in case of power failure. The on-board capacity for voice mail is 34 minutes. Each EVM200L module has four expansion slots for the optional EVM-DL cards. A 34-minute DRAM memory field is present on each EVM-DL card, in order to be used for voice mail.

Each EVM200L has 8 voice channels in total, 4 for message recording and 4 for listening to recorded messages. The 4 recording channels are used to record the ACD or system messages, or they are used while recording messages that extensions are leaving to each other. The 4 announcement channels, on the other hand, are used during announcement of the ACD or system messages to users, or they are used by extensions to listen to messages left for them.
