Technical Description of TANDBERG Gateway with software version G2

4.1.8TANDBERG 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:

Bandwidth	64	128	192	256	320	384	512	768	1152	1472	1920
Non-encr.	74	80	82	84	88	92	108	124	160	176	220
Encrypted	106	118	120	122	136	146	168	222	N/A	N/A	N/A

Telephone calls:

Bandwidth	Telephone
Non-encr.	22
Encrypted	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.
