ConnectingtheBRIS/TBackup

Port to the Network

If your Cisco MC3810 supports BRI S/T backup,

connect the BRI S/T backup port to the ISDN

network.

Use an 8-conductor straight-through cable (not

included).

Step 1 Connect one end of the cable to the port

labeled BRI 0 S/T on an orange

background.

Step 2 Connect the other end of the cable to the

S/T interface of the NT1.

Step 3 If the NT1 is not already connected to the

ISDN network, connect the U interface of

the NT1 to the ISDN wall jack

(U interface).

Note: Step 3 should only be necessary in locations

wheretheUinterfaceisaccessible to the user, such as

in the United States.
