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:

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).
