T1/PRI Line

If the distance is more than 655 feet or 200 meters (up to 6200 feet or 1.8 kilometers), you must connect the board in a DS1 (long haul) configuration. In the DS1 configuration, a Channel Service Unit (CSU) must translate the short haul DSX1 interface to support the longer distance. The 5536-DM RAS board includes an internal CSU, which enables it to connect directly to the T1/PRI line in a DS1 configuration.

Connecting Directly to the Line

Direct connection is subject to constraints imposed by FCC rules and by your partner carrier. To see if you can connect directly to the interface, and for more information about direct connection constraints, contact your carrier.

WARNING

To avoid harming the WAN, contact your carrier for approval before connecting the board directly to the line.

CAUTION

In accordance with FCC Rules, Part 68.218 (b), you must notify the telephone company prior to disconnecting the board from the line or turning off the power to the board’s host system. Without this prior notification, the carrier might temporarily discontinue your T1/PRI service.
