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.
Making the Physical Connection
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
Figure 5-3. The Serial Module Connects Directly to an External CSU/DSU.
The serial module ships with either a V.35 cable or an X.21 cable.
ProCurve Networking does not currently provide an EIA 530 cable.
