MultiChannel Connections

For the MIP, two standard T1 serial cables are available from Cisco Systems and other vendors for
use with the MIP: null-modem and straight-through. These interface cables are used to connect your
router to external CSUs.
The cables have male 15-pin DB connectors at each end to connect the MIP with the external CSU.
Connect the T1 cable as shown in Figure 3-25.

Connecting the Console Terminal

The system console port on the RP (or RSP7000) is a DCE DB-25 receptacle for connecting a data
terminal, which you will need to configure and communicate with your system. The port is located
on the RP (or RSP7000) below the auxiliary port and is labeled Console. (See Figure 3-26.)
Note
these ports must be capable of asynchronous transmission. (Asynchronous is the most common type
of serial device; for example, most modems are asynchronous devices.)
