Electra Elite IPK II
The T1/PRI Interface ETU provides Tie Line service. All programming parameters are the

same as those used for analog Tie Lines (except for the additional T1/PRI Interface ETU
settings).
DTI-U40 ETUs can be installed in any Interface slot (1~8) of any cabinet (1~3).

The DTI-U40 ETU supports Dial Pulse and DTMF signaling.

With an Electra Elite IPK II – Expanded Port Package, up to 200 T1 trunks can be

assigned.
You can use T1 trunks in place of standard analog trunks. The procedures for placing and

answering calls are the same for both types of trunks.
The T1/PRI Interface ETU provides DID service. All programming parameters are the same

as those used for analog DID trunks (except for the additional T1/PRI Interface ETU
settings).
SMDR can print trunk port names or received dialed number for ANI/DNIS or DID trunks. If

enabled in programming, DNIS digits can be printed on the SMDR reports instead of the
trunk name.
T1 trunks follow Tie Line toll restriction programming (PRG 34-01-05 and PRG 34-08).

When using Fractional T-1s, the card comes up with zero ports until PRG 10-03-06 is set to

the 4/8/12/16/20/24(auto) and then reset.
If the number of ports are changed for a fractional T-1 in PRG 10-03-06, the trunk ports

could be reassigned if the numerical sequence would split or it could fit into an empty gap of
trunk ports. Version 1500 or higher with PRG 10-39-01 set to Enabled is required.
Examples:
The COI(8) ETU is assigned for trunk ports 1~8 and 17~24 and the T-1 (12 ports) was
assigned as ports 25~36, the number of T-1s change to eight ports instead of 12. The new
trunk port numbers are assigned as 9~16 because the eight ports can fit into the gap
between ports 8 and 17 without splitting the numerical port number sequence.
The COI (8) ETU is assigned for trunk ports 1~8 and 17~24 and the T-1 (eight ports) was
assigned as 9~16 and then the T-1 was changed from eight to 12 ports. The new trunk port
numbers are assigned as 25~36 because the port number sequence would have to be split
in order to keep them within the original number sequence (9~16) and splitting the
numerical port number sequence is not supported.
