Setting the Signaling Protocol Used by
D/240PCI-T1 Linecards
The default signaling protocol set by the Dialogic System Software for D/240PCI-T1
linecards is E&M wink-start signaling. This section explains how to create and configure
a new system environment variable to accommodate T-1 carriers that require different
signaling protocols. There are two separate T-1 protocol selections you must make for
your system:
•
E&M or FXS/FXO signaling
•
Wink start or immediate start
In OneBox, E&M signaling defaults to wink start and FXS signaling defaults to
immediate start. OneBox defaults to E&M signaling and must be changed to FXS
signaling.
To change from E&M signaling to FXS signaling:
1.
Log on to Windows NT Server with an account that has local Administrator
privileges on the OneBox platform.
2.
From the Start menu, point to Settings and select
Control Panel
.
3.
In Control Panel, double-click the
System
icon.
4.
At the System Properties dialog box, click the Environment tab.
5.
From the System Variables list, select the first variable.
IMPORTANT
All variables described in this procedure are case sensitive.
6.
In the Variable box, type
T1_PROTOCOL_FILE
.
