Chapter 2 Preparing to Install the Cisco AS5350XM Universal Gateway

Preparing to Connect to a Network

Auxiliary Port

The Cisco AS5350XM universal gateway includes an EIA/TIA-232 asynchronous serial auxiliary port (RJ-45) that supports flow control. Depending on the cable and the adapter used, this port will appear as a DTE or DCE device at the end of the cable. Your universal gateway arrives with a cable and an adapter to connect a modem to the auxiliary port. To connect a modem to the auxiliary port, use the RJ-45 rollover cable with the male RJ-45-to-DB-25 adapter (labeled MODEM).

For detailed information about connecting devices to the auxiliary port, see Chapter 3, “Installing the Cisco AS5350XM Universal Gateway.” See Appendix C, “Cabling Specifications,” for cable and port pinouts.

2T Serial Ports

Two high-speed 12-in-1 serial ports on the rear panel of the Cisco AS5350XM universal gateway provide backhaul WAN and IP support.

The following types of serial interface standards (in DTE or DCE devices) are supported:

•EIA/TIA-232

•EIA/TIA-449

•EIA/TIA-530

•EIA/TIA-530A

•EIA/TIA-X.21

•ITU-T V.35

Each interface supports up to 8 Mbps.

Alarm Port

The three pins on the alarm port are connected to the output of a relay. This relay is controlled by system software. To configure the alarm port, see the Cisco AS5350XM and Cisco AS5400XM Universal Gateways Software Configuration Guide. This document is available on Cisco.com. (See the “Obtaining Documentation” section on page xiv .)

With the alarm port connected and configured, Cisco IOS software polls the universal gateway every one second to detect the failure events that occur and turns on the alarm when it detects any failure event. See Appendix C, “Cabling Specifications,” for pinouts and cable specifications.

BITS Port

The BITS port is a coaxial interface that provides external synchronized clocking through a timing signal generator (TSG). To configure the BITS port, see the Cisco AS5350XM and Cisco AS5400XM Universal Gateways Software Configuration Guide. This document is available on Cisco.com. (See the “Obtaining Documentation” section on page xiv .) See Appendix C, “Cabling Specifications,” for pinouts and cable specifications.
