Inserting a cartridge / 231 P0603534 02Modular ICS 6.1 Installer Guide Inserting a cartridge Close clips simultaneously. It is important to center and close the two clips on the cartridge simultaneously, otherwise the cartridge may become misaligned in its slot or with its connector. If improperly inserted, the connector will be damaged. PCB is electrostatic-sensitive. Do not touch the printed circuit board on a cartridge. This is an electrostatic-sensitive device.

Install trunk cartridges in the trunk modules beginning with Slot 1 then Slot 2 and then Slot 3. For easier wiring, install similar type Trunk Cartridges together in the same Trunk Module. If you install an E&M or a DID or BRI Trunk Cartridge in the left-most slot (slot 1) of a TM, emergency telephones cannot be supported for that Trunk Module. Terminating resistors on BRI-ST Cards The standard ISDN user-network interface wiring requires terminating resistors at each end of the loop for point-to-point operation. This ensures correct timing of the signaling circuits. Loop termination can be provided at either the point where the ISDN terminal is attached, or by the device attached to the loop which has built-in termination. Because the Modular ICS is usually at one end of the loop, the BRI-ST card is shipped with termination built-in for each ISDN loop. It is ready to be used where the ICS is located at one end of the loop, as in the following illustration: ICS Built-in termination installed TE connections without termination TE with termination
Inserting a cartridge / 233 P0603534 02Modular ICS 6.1 Installer Guide Shorting straps on a BRI-ST card Ensure that the shorting straps are installed on both the receive and transmit jumpers for the loop. Refer to the illustration above. The jumpers are numbered top to bottom, but the loops associated with each pair of jumpers does not follow the same top-to-bottom sequence. Refer to the table on the next page. J8 J7 J6 no shorting strap termination removed termination installed
234 / Inserting a cartridge Modular ICS 6.1 Installer GuideP0603534 02 Receive and transmit jumper loop connections Connecting expansion modules If your system includes fiber Trunk Modules, fiber Station Modules, Data Modules or Analog Station Modules, you need to connect the modules to the Expansion Cartridge by means of fiber cables. Order of connection In order to keep the default port and telephone numbering: • Connect Trunk Modules to the Expansion Cartridge beginning at the top and working down. • Connect Station Modules to the Expansion Cartridge beginning at the bottom and working up. Analog Station Module If you are installing the ICS system with an ASM, refer to the diagram below. Connect jack 1 on the ASM to the first available fibre cable link on the CCU.

The ASM has three connectors, two fibre cable links and a 25-pair pin connector. Refer to the wiring section for the pinout for the 25-pair pin connector.

Connect jack 1 on the third ASM to the next available fibre cable link on the ICS. 3. The fourth module is connected to the third, and so on. 4. Each fibre cable link can support two ASMs. Connecting multiple modules After the modules are mounted and connected, feed the cables through the cable trough.

Inserting a cartridge / 237 P0603534 02Modular ICS 6.1 Installer Guide Two-port Expansion Cartridge Tips - On a midi system, ports 3 and 4 can be used for Trunk Modules or Station Modules. In this case, connect Trunk Modules beginning at the top (port 4). Connect Station Modules beginning at the bottom (port 3). On a maxi system, ports 3 through 8 can be used for Trunk Modules or Station Modules. In this case, Trunk Modules should be connected beginning at the top (port 8) and working down. Station Modules should be connected beginning at the bottom (port 3) and working up. On a fully expanded 12-port (mega) system, connect Trunk Modules beginning at the top (port 8) and working down. Station Modules would be connected beginning at the bottom (port 3) and working up. Trunk Modules cannot be connected to the Expansion Cartridge in slot 1. When no more Station Modules can be added to the Expansion Cartridge in slot 2, connect additional Station Modules to the Expansion Cartridge in slot 1, beginning at the bottom (port 9) and working up.

240 / Installing fiber cables Modular ICS 6.1 Installer GuideP0603534 02 Installing fiber cables Installing fiber cables. Fiber cables are durable, but can be damaged. Damaged cables can affect the transmitted signals. To avoid damaging the cables, observe the following: Coil excess fiber cable on the spool provided for the installation. Secure the fiber cable spool in the ICS cable trough. Ensure that bends in the cable are no tighter than 100 mm. (4 in.) in diameter. When using cable ties, bundle fiber cables loosely. Avoid excessive pulling, compression or impact. Do not grasp the fiber cable, or the clasp where the cable joins the plug, when connecting or disconnecting a fiber cable plug into a port. Do not leave fiber cables in an environment with excessively high temperatures (for example, on top of radiators).
