Issue 1.0
Conditions
Primary Rate Interface (PRI):
The system is compatible with ISDN Primary Rate Interface (PRI) services. PRI services
currently supported include:
Basic PRI Call Control (BCC)
Display of incoming caller's name and number when allowed by Telco
Routing in the system based on the number the caller dialed
ISDN maintenance functions (such as In Service/Out of Service Messaging)
Speech and 3.1 KHz audio
PRI capability requires the installation of CD-PRTA. Each PRI circuit provides 24 PRI
channels (23B + D) 4 with 64K Clear Channel response. The T1/PRI Interface uses a single
slot. When installed, the T1/PRI Interface uses the first block of 24 consecutive trunks. For
example, if you have an CD-4COT + PZ-4COT installed for trunks 1~8, the T1/PRI Interface
will automatically use trunks 9~32. If you have CD-4COT + PZ-4COT installed for trunks 1~8
and 17~24, the T1/PRI ETU will use trunks 25~48. The T1/PRI Interface cannot use trunks
9~16 (even if available) since they are not part of a consecutive block of 24 trunks.
When using fractional PRI, the blade comes up as zero ports until Program 10-03-06 is set to
the 4/8/12/16/20/24(auto), and then reset.
If fractional PRI has the number of ports changed, the Trunk Port number might change if
they become split or fit into an empty gap of trunk ports. For example, if you have a CD-
4COT + PZ-4COT for Trunks ports 1~8 and 17~24 and the PRI (12 ports) was assigned as
25~36 and the PRI is changed to be eight ports instead of 12 ports, the new trunk port
numbers would be 9~16 because the eight ports can now fix into the gap without being split
ports. Another example, if you have a CD-4COT + PZ-4COT for Trunks ports 1~8 and
17~24 and the PRI (8 ports) was assigned as 9~16 and then you change the PRI to be 12
ports instead of eight, the new trunk ports would be 25~36 because the ports have to be split
to keep the original port numbers, and this is not supported.
If using a CSU/DSU, Program 10-03-13 must be set to 0. If not using a CSU/DSU, Program
10-03-13 must be set to 1~7 or anything other than 0.
Restrictions for Calling Party Name:
The UNIVERGE SV8100 supports receiving the name from the Network (if provided) in
supported formats only and cannot send the Calling Name. This is network dependant.
