Connecting the 1-Port T1/FT1 DSU/CSU Modules
This section describes how to connect and verify the status of the 1-port T1/FT1 DSU/CSU interface
module (WIC-1DSU-T1).
Use a straight-through RJ-48S-to-RJ-48S or the straight-through RJ-48C-to-RJ-48C cable that shipped
with the AGM.
To connect the 1-port T1/FT1 module, perform these steps:
Step 1 Power off the AGM.
Step 2 Connect one end of the cable to the T1/FT1 port of the module, as shown in Figure 2-5.
Step 3 Connect the other end of the cable to the RJ-48S wall jack, as shown in Figure 2-5.
