Electra Elite IPK II
PRI ability 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 automatically
uses trunks 9~32. If you have COI (8)-U( ) ETUs installed for trunks 1~8 and 17~24, the T1/
PRI ETU uses 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. (Version 1100 or
lower and Version 1500 or higher when PRG 10-39-01 is Disabled.)
When using fractional PRI, the card comes up as zero ports until PRG 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 would become split or could fit into an empty gap of trunk ports. For example, if you
have a COI(8) ETU 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 COI(8) ETU 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 would have to be split to keep
the original port numbers, and this is not supported. (Version 1500 or higher is required
when PRG 10-39-01 is Enabled.)
If using a CSU/DSU, PRG 10-03-12 must be set to Short, and PRG 10-03-13 set to 0. If not

using a CSU/DSU, PRG 10-03-12 must be set to Long, and PRG 10-03-13 must be set to
1~7 or anything other than 0.
