Network Interfaces
E1/T1 Network Interface Card (IIC-8) (3:3)
PRI T1 (US only)
PRI T1 (US only)
Network Service Facility (NSF) can be configured to mode Off (i.e. NSF not
used – default) or mode On with any value between 0 and 31, to describe
the service facility on the PRI/T1 line.
ISDN Aggregation Standards
H.221
1. Frame Structure from 64 (56*) kbps to 128 kbps
ISO 13871
2. BONDING, Mode 1 from 64 (56*) kbps to 2 Mbps
H.221
•
For bit rates from 56 kbps up to 128 kbps (1 or 2 channels).
•
The maximum relative delay difference between the 2 B-channels is 0.6
second.
BONDING
•
ISO 13871, BONDING Mode 1 for bit rates from 56 kbps up to 2 Mbps
(1 to 30 channels).
•
The maximum relative delay difference between B-channels is 0.5 sec-
ond (i.e. to compensate for different routing of channels).
Standard bandwidths on H.320
30ch – 24 – 23 – 18 – 12 – 8 – 6 – 5 – 4 – 3 – 2 – 1
ISDN Channel Setup
The following is a description of how the ISDN channels are set up.
•
Incoming & Outgoing MCU calls : Normally the MCU will set up only 1
channel from PRI 1 and build up the channels starting from the bottom
of the last PRI in use.
•
This will ensure that the MCU always have available channels on the
first PRI number (which normally should be the MCUs main number).
•
The TANDBERG MPS supports simultaneous dial in to the same confer-
ence on ISDN.
