secondary reference clock. These reference clock sources are derived from either BRI spans or DSLs (DSL 0 and/or DSL 1).

Note 2: A clock controller is required in every cabinet or MG 1000S that contains a digital trunk.

5Install the SILCs and UILCs. See Procedure 17 "Installing the SILCs and UILCs" (page 61).

6Remove the SILCS and UILCs, if previously installed. See Procedure 18 "Removing the SILC and UILC" (page 64).

7Install the PRI hardware. See Procedure 19 "Installing the PRI hardware" (page 64).

Note: This step is required for packet data implementation only.

8Connect the ISDN BRI terminals or trunks.

a.Connect the ISDN BRI terminals for line applications:

1.Connect system cables to the cross-connect terminal. See Procedure 20 "Connecting system cables to the cross-connect terminal" (page 66).

2.Cross-connect the DSLs at the cross-connect terminal. See Procedure 21 "Cross-connecting the DSLs at the cross-connect terminal" (page 70).

3.Connect the terminating resistor to the SILC DSL. See Procedure 22 "Connecting the terminating resistor to the SILC DSL" (page 74).

4.Connect the ISDN BRI terminals to the DSL. See Procedure 23 "Connecting the ISDN BRI terminals to the DSL" (page 76).

5.Initialize a Nortel Networks M5317TDX terminal. See Procedure 24 "Initializing a Nortel Networks M5317TDX terminal" (page 80).

b.Connect the ISDN BRI trunks for trunking applications:

1.Connect the system cables to the cross-connect terminal. See Procedure 25 "Connecting the system cables to the cross-connect terminal" (page 82).

2.Cross-connect the DSLs at the cross-connect terminal. See Procedure 26 "Cross-connecting DSLs at the cross-connect terminal" (page 83).
