Chapter 3 Installing the Router
Connecting the Network Cables
Table 3-1 lists the pinouts and signals for the RJ-45 port.
Connecting the VWIC Interface Cables
How you connect the ports of the T1/E1 Multiflex VWIC depends on whether you are using the
MWR 1941-DC router in a redundant (IP-RAN implementations only) or a non-redundant configuration.
For redundant configurations, use a Y-cable (as described in Y-Cable Specifications, page 3-7 ).
Note
HSRP and the Y-cable mode must be configured for redundancy to allow one router to become active
(CD LED on, AL LED off) and the other to become the standby CD LED off, AL LED on due to no
framing). For more information, see the
MWR 1941-DC 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.
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 1941-DC 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.
