TANDBERG Gateway
Configure the Gateway
Interface Configuration
This section configures each of the four PRI interfaces individually. There is one column for each PRI Interface.
However, if PRI Trunk Grouping is enabled, the number range for PRI 1 will also apply for PRI 2, 3 and 4.
Number Range Start
The PRI lines connected to the gateway should have at least one number each, to allow dial in from ISDN.
In order for the gateway to handle two or more simultaneous incoming ISDN calls for the ISDN services IVR and
TCS-4, it is required to define a PRI number range in addition to the IVR number.
THE QUANTITY OF SIMULTANEOUS INCOMING ISDN CALLS IS
DEFINED
AS PRI NUMBER RANGE MINUS IVR AND HOTLINE
NUMBER (IF USED).
NOTE
If the PRI line has a range of numbers, the start number
must be entered here. Please contact your IT manager to
obtain these numbers.
It is only necessary to enter the digits indicating the range. If the range is 67124000 to 67125000, then just enter
4000. Maximum amount of digits is 24.
Number Range Stop
Here is where the last number in the PRI number range is entered. If the range is 67124000 to 67125000, then
just enter 5000.
PRI CRC-4
Used for most E1-PRI configurations. If your network equipment does not support this feature, set PRI CRC-4 to
Off.
T1 Cable Length
Specifies the cable length between the gateway and the CSU for each of the PRI lines (only valid for T1 networks).
Possible values are:
• 0 to 133 feet
• 133 to 266 feet
• 266 to 399 feet
• 399 to 533 feet
• 533 to 655 feet
