Cable; Procedure; Connecting A T1/E1-Wan Port To The Network Demarcation Device - Cisco IAD2430 Series Hardware Installation Manual

Connecting Cables
•
DTE ports require external clocking provided by a DCE device such as a CSU/DSU.
Note

Cable

The type of cable you connect to the serial port automatically sets the port for DTE or DCE operation
and establishes the signaling standard.

Procedure

Use the procedure in this section to connect external equipment to the Cisco 2430 series IAD.
