Serial Interface: Configuring the Physical

Because the external CSU/DSU manages timing, framing, and signaling for the

E1- or T1-carrier line, the serial interface does not have to perform these

functions. Consequently, you do not need to configure options to control these

functions. As a result, the serial interface requires only minimal configuration.

To connect the serial module to the CSU/DSU, you will need one of the

following cables. (See Figure 5-3.)

EIA 530 cable

Serial V.35, X.21,

or EIA 530 cable
