The SILC can recover the network clock from the received data stream using on-chip phase lock loops. The clock frequency that is recovered is 2.56 MHz. The jitter and wander conform to CCITT recommendations.

All of the S/T chips on the SILC could be configured as Terminal Equipment Slaves (TES), but only the clocks recovered from DSL0 and DSL1 are routed to the back plane connector pins. These clocks are provided as differential pairs on back plane pins. See Table 9 "Clocks as differential pairs" (page 42).

Automatic clock recovery is done upon the expiration of the free run guard timer. Tracking is restored to the primary reference clock, if defined. If the primary reference clock is disabled, tracking is restored to the secondary reference clock, if defined.

Installing the SILC and the UILC

Follow the same procedures as described earlier for line applications (refer to Procedure 5 "Installing the BRSC, SILC, and UILC" (page 22)).

Connecting the system to the Main Distribution Frame (MDF)

Follow the same procedures as described earlier for line applications (refer to Procedure 8 "Connect the modules to the MDF" (page 24)).

Cross-connecting the Main Distribution Frame (MDF)

The system, 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 "Connect the network termination to the U interface and to the S/T interface (in TE mode)" (page 43).
