Subscriber ISDN BRI Installation
(Option 11C).

Install ISDN BRI hardware

The following procedures should be followed in the order shown. These procedures apply for line, packet data, and trunking applications. Please note, however, that certain procedures may only apply for line, packet data, or trunking.
The Option 11C system should already be installed and operational before performing these procedures.

1. Select the card slots.
2. Install the MISPs.
3. Install the clock controller on the MISP, if required.

Note 1: A clock controller is required for ISDN BRI trunk applications only. The Option 11C system supports a single active clock controller (CC). This clock controller can support both a primary and a secondary reference clock. These reference clock sources may be derived from either BRI spans or DSLs (DSL 0 and/or DSL 1).
Note 2: A clock controller is required in every cabinet that contains a digital trunk.

4. Install the SILCs and/or UILCs.
5. Install the PRI hardware.
   Note: This step is required for packet data implementation only.
6. Connect the ISDN BRI terminals (for line applications).
   • Connect the Option 11C cables to the cross-connect terminal. Why does this not work
     
   • Cross-connect the wiring.
     
   • Connect the terminating resistor to the end of the SILC DSL.
     
   • Connect the ISDN BRI terminals to the DSL.
     
   • Initialize the terminals.

7. Connect the ISDN BRI trunks (for trunking applications).
   • Connect the Option 11C cables to the cross-connect terminal
     
   • Cross-connect the DSLs

Select the card slots

Refer to Table 1 for ISDN BRI circuit card assignments in the main cabinets.
Identify the card slots in the Option 11C cabinets that will house the ISDN BRI cards.
The following rules apply when selecting the card slots:

• MISPs are inserted in the main cabinet in any available slots 1-9 of the Main cabinet, or in slots 11-19, 21-29, 31-39, 41-49 of the first, second, third, and fourth IP Expansion cabinets, respectively
• One MISP supports a set of four SILCs or UILCs, or a combination of both SILCs and UILCs.
• SILCs and UILCs can be installed in slots 1-9 of the Main cabinet, or in slots 11-19, 21-29, 31-39, 41-49 of the first, second, third, and fourth IP Expansion cabinets, respectively.

Install the MISP

1. Remove the cover from the main cabinet.
2. Remove the MISP from its shipping package and hold it by its card locking devices.
   Note: While performing the next step observe the LED on the faceplate of the MISP.

CAUTION
The static discharge bracelet located inside the cabinet must be worn before handling circuit cards. Failure to wear the bracelet can result in damage to the circuit cards.

3. Insert the MISP into the selected card slot and lock it in place.
4. The LED should light, flash three times then remain lit to indicate that the MISP is operating correctly but is not configured and enabled.

5. The LED should light, flash three times then extinguish to indicate that the MISP is operating correctly and is configured and enabled. Any other LED indication suggests a defective MISP circuit card.

Note: The Flash ROM can become corrupted if loss of power occurs during programming of the Flash ROM. If this occurs, the Flash ROM will automatically be re-initialized when the MISP is installed (powered up). This operation will delay the completion of the self-test, and it will take five minutes for the LED to flash three times. (see additional *NOTE below).

6. Repeat the steps in this procedure for each MISP being installed.

Install the SILC and UILC

1. Remove the cover from the assigned cabinet.
2. Remove the SILC or UILC from its shipping package and hold it by its card locking devices.
3. Configure the line powering options for the SILC using the jumper plugs.

Each port is equipped with its own set of option jumper plugs to allow individual configurations for each DSL.
The SILC has three line powering options. These options are configured using the jumpers located near the backplane connector as shown in Figure 1.

CAUTION
The static discharge bracelet located inside the cabinet must be worn before handling circuit cards. Failure to wear the bracelet can result in damage to the circuit cards.
