PRI capability requires the installation of DTI-U40 ETU with PRT Firmware version 5.XX or
higher. Each ETU (also called a PRI circuit) provides 24 PRI channels (23B + D) 4 with 64K
Clear Channel response. The T1/PRI Interface ETU uses a single slot. When installed, the
T1/PRI Interface ETU uses the first block of 24 consecutive trunks. For example, if you
have an COI (8)-U( ) ETU installed for trunks 1-8, the T1/PRI Interface ETU will
automatically use trunks 9-32. If you have COI (8)-U( ) ETUs 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.
Restrictions for Calling Party Name:
The Electra Elite IPK II supports receiving the name from the Network in supported formats

B-Channel to Trunk Association
When an Incoming ISDN-BRI/PRI call is received, the system will assign the lowest trunk
number of the ISDN circuit to the incoming call associated with the B-Channel. When an
Outgoing call is placed using the ISDN-PRI/BRI, the system will assign the Trunk and B-
Channel association according to the chart below. This is based on the Trunk to Trunk
Group and Trunk Group Priority assignment in (PRG 14-05-01).
