Connect the Serial Port for WAN Access
Use a serial 12-in-1 cable (DTE if connecting to a DSU or DCE if connecting to a CSU) to connect one of the four synchronous
serial ports on the E1 or T1 PRI cards (with serial support) to a modem or a CSU or DSU. The CSU or DSU provides access to
a WAN.
Step 1 Connect the serial 12-in-1 cable connector on the serial cable to the serial port on the rear panel of the Cisco AS5300.
Step 2 Connect the EIA/TIA-232, EIA/TIA-449, EIA/TIA-530A, EIA-530, V.35, or X.21 connector to the CSU or DSU.
