Caution
To comply with GR-1089-Core intra-building lightning-immunity requirements, you must use shielded
(screened) cable that is grounded at both ends.
Connecting Cable Interface Line Card Cables
The instructions for connecting the cables for each cable interface line card installed in the
Cisco uBR7225VXR universal broadband router are contained in the cable interface line card
installation document. Refer to the

Console and Auxiliary Port Connection Equipment
The NPE contains the console and auxiliary ports. The console port is a RJ-45 receptacle for connecting
a data terminal, which you use to configure the interfaces and bring up the Cisco uBR7255VXR router.
The auxiliary port is a RJ-45 receptable for connecting a modem or the other DCE device (such as a
channel service unit/data service unit [CSU/DSU]) to the router. (See
Figure 3-12 on page 3-14 .)
Note
Both the console and auxiliary ports are asynchronous ports; any devices connected to these ports must
be capable of asynchronous transmission. (Asynchronous is the most common type of serial device; for
example, most modems are asynchronous devices.)
