Install ISDN BRI hardware for trunk applications

The following lists the procedures for install ISDN BRI hardware for ISDN BRI trunk applications. Meridian 1 must already be installed and operating according to the instructions in System Installation Procedures (553-3001-210) before performing these procedures.

For a successful installation, perform these procedures in the order listed below:

1Select the card slots where the ISDN BRI cards will be located

2Install the MISP

3Install clock referencing on the SILC

4Install the SILC and/or UILC

5Connect Meridian 1 to the MDF

6Cross-connect the MDF (in Terminal Equipment mode)

Note: The Meridian 1, in Tie trunk or CO connectivity, requires a different wiring configuration than for a line application; the transmit and receive pairs should be reversed, as illustrated in Figure 12.

Select the card slots

Follow the same procedures as described earlier for line applications (refer to “Select the card slots” on page 15).

Remove the module cover for card installation

Follow the same procedures as described earlier for line applications (refer to “Remove the module cover for card installation” on page 19).

Install the MISP

Follow the same procedures as described earlier for line applications (refer to “Install the MISP” on page 20).

Install the clock reference on the SILC

The DSL#0 and DSL#1 on an SILC card can be configured as the reference clock source, with DSL#0 being assigned for the primary clock reference and DSL#1 being assigned for the secondary clock reference.
