ESI 900 - Function 212: T1 programming; Function 2121: Line programming

IP Server 900 Programming Manual Function 2: CO line programming
E.8
Using the T1/PRI Module:
An overview (Functions 212 through 2135)
The T1/PRI Module enables the IP Server 900 to support these high-bandwidth lines.
The following chart gives more details:
Description
Compatible with IP Server 900
Installability One module/carrier, two modules/cabinet
PRI/T1 support Either a T1 interface supporting 24 DSO channels or an ISDN PRI interface supporting
23 B (bearer) channels and one D (datalink) channel
Digital/analog support None
Jumper placement for PRI Location J2, horizontally onto pins 7 and 8
Notes: If jumper J2 is removed from or added to an already installed T1/PRI Module, all CO line programming
will return to system defaults, and all of the systems’ stations will revert to default settings for station
options (hands-free answer, call waiting, background announce, monitor mode, outside dialtone
preference, headset operation, etc.).
Mailbox 598 is a special-purpose mailbox for monitoring T1/PRI alarms. Whenever the system detects a
severe T1 or PRI alarm, it will store a message in this mailbox. You also can program outdial notification
(in mailbox settings) to alert someone when the system detects such an alarm.
See “Function 7: Reports” (page J.1) for reports on PRI activity.
Function 212: T1 programming
This function allows you to program the trunks and line parameters for a T1/PRI Module. The system will identify
the number of T1/PRI Modules installed
1
and allow you to scroll through the 24 channels on each T1/PRI Module.
T1 PROGRAMMING
Function 2121: Line programming
Note: Set trunk type emulation, as explained below, before proceeding to name any line.
The first line of the display will show the carrier card number, the type of module, and a D or N for day or night
mode; the second line will show the COs available to program. All programmable key LEDs will glow red until
selected for programming.

See “System capacities,” beginning on page B.1, for a table of maximum T1/PRI Modules per system.
