Chapter 3 Installing the Router

Connecting the Network Cables

Note If you choose to use the T1/E1 Multiflex VWIC in a non-redundant configuration, you must close

the relays on the card using the standalone subcommand. For more information, see the “Cisco MWR

1900 Software Configuration Guide.”

Step 1 Confirm that the router is turned off.

Step 2 Connect one end of the cable to the T1 or E1 port on the card.

Step 3 Connect the other end to the BTS patch or demarcation panel at your site.

Step 4 Turn on power to the router.

Step 5 Check that the CD LED goes on, which means that the card’s internal CSU/DSU is communicating

with the CSU/DSU at the T1 or E1 service provider central office.

The T1/E1 Multiflex VWIC uses an RJ-48C connection, as shown in Figure 3-4.

Table 3-2 shows the pinout configuration of the RJ-48C connectors on the T1/E1 Multiflex VWIC.

Y-Cable Specifications

Although it can be used in a standalone MWR 1900 router, the T1/E1 Multiflex VWIC is designed to be

used in redundant configurations. Such configurations require a special Y-cable for connecting the active

and standby routers. The Y-cable provides a dual E1 or T1 PRI connection.
