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:
1 Select the card slots where the ISDN BRI cards will be located
2 Install the MISP
3 Install clock referencing on the SILC
4 Install the SILC and/or UILC
5 Connect Meridian 1 to the MDF
6 Cross-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.
