To connect a T1/FT1 DSU/CSU WIC to a network, follow these steps:
Step 1
Confirm that the router is turned off.
Caution

connect the 1-port T1/FT1 DSU/CSU WIC, version 2 (WIC-1DSU-T1-V2) only to intra-building or
non-exposed wiring or cabling. The intrabuilding cable must be shielded and the shield must be
grounded at both ends.
Step 2
Connect one end of the straight-through RJ-48C-to-RJ-48C cable to the RJ-48C port on the T1/FT1
DSU/CSU WIC.
Step 3
