Connecting the VWIC Interface Cables

How you connect the ports of the T1/E1 Multiflex VWIC depends on whether you are using the MWR

1900 router in a redundant or a non-redundant configuration.

For redundant configurations, use a Y-cable (as described in Y-Cable Specifications, page 3-6).

Note HSRP and the Y-cable mode must be configured for redundancy to allow one router to become active

(CD LED on) and the other to become the standby (CD LED on, AL LED on due to no framing). For

more information, see the MWR 1900 Software Configuration Guide.

Step 1 Confirm that both routers are turned off.

Step 2 Connect the end of one of the Y-cable stubs to the T1 or E1 port on the card on the first router.

Step 3 Connect the end of the other Y-cable stub to the T1 or E1 port (using the same type of port as in Step 2)

on the card in the second router.

Step 4 Connect the other end of the Y-cable to the BTS patch or demarcation panel at your site.

Step 5 Turn on power to the routers.

Step 6 Check that the CD LEDs goes on, which means that the cards’ internal CSU/DSU is communicating

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

For non-redundant configurations, use a straight-through, shielded RJ-48C-to-RJ-48C cable.
