Interphase Tech 5536 Network Card User Manual


 
T1/PRI Line
28 Interphase Corporation
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.
