Installing ISDN BRI hardware for trunk applications 41
Procedure 12
Connecting clock reference cables
Step Action
1 Search for available D-sub 9 connector slots on the I/O panels of the
selected IPE and CE I/O modules (if the I/O panel is equipped with
D-sub 9 connector slots). If none is available, look for an empty slot
used for 25-pair wire connectors (the cables contain two adapter
plates to convert a 25-wire slot to two D-sub 9 connector slots).
2 Connect the cables as shown in Figure 11 "Clock reference cable
connection" (page 41) ; if choosing IPE slots 0, 4, 8, or 12, remove
the transmit and receive cable installed on pins 72 - 79 and secure
them to a proper place.

The SILC is configured in the slave-slave mode when acting as a trunk
interface. This is configured through the Maintenance Signaling Channel
(MSC). The microcontroller configures the S/T chips on the SILC as
appropriate.
