Disconnect Time (default: 60 minutes) set in Memory Block 1-4-00

Tandem Switching of E&M Tie Lines can be accomplished through

several Electra Elite systems.

individual station users access to specific E&M Tie Lines. Each
station can be programmed to restrict the maximum number of digits
dialed on an E&M Tie Line by assigning Code Restriction.
Access to outside lines by an E&M Tie Line user is recorded by
¥
SMDR where the CO line is connected. The originating system may
also record the Tie Line user using its own SMDR.
Tandem connection can be allowed/denied per Trunk group for one
¥
or both directions.
Assigned Tie/DID lines can add/delete up to two digits per Trunk
¥
group.
