4.1.8 TANDBERG Gateway Capacity
The total capacity of the TANDBERG Gateway is defined by the following rules.
I. Maximum 8 video calls and 8 telephones calls.
II. Total system bandwidth (IP + ISDN) of the TANDBERG Gateway is 7680 kbps. The
maximum bandwidth used for ISDN calls is depending on the number and type of
PRI's installed:
a) The maximum bandwidth for each ISDN E1 is 1920 kbps (30x64kbps).
b) The maximum bandwidth for ISDN T1 is 1472 kbps (23x64kbps).
III. In addition, each call has a Call Weight depending on bandwidth and encryption as
follows:
Video calls:

Telephone calls:

N/A
The total sum of the Call Weights on the TANDBERG Gateway can not exceed 845.
(Users will be prevented from setting up calls that exceeds this limit).
Example of call weight calculation:
If the TANDBERG Gateway has made 1 encrypted call at 768kbps and two unencrypted calls at
384kbps the calculation will be:
222 + 2(92) = 222 + 184 = 406
Since 406 is less than 845, this will be OK.
