Programming Procedures
Lines and Trunks
The procedures in this section are used to assign optional features to individual
lines and trunks. The following optional features can be assigned:
■
Type of Trunk
■
Outmode Signaling for Loop- or Ground-Start Trunks
■
Rotary Trunk Digit Transfer
■
Disconnect Signaling Reliability
■
Toll Type
■
Hold Disconnect Interval
■
Principal User for Personal Line
■
QCC Queue Priority
■
QCC Operator to Receive Calls
■
Incoming Call Line Identification Delay
■
Trunks to Pools Assignment
The Copy Options feature (described at the end of this section) allows you to
copy several optional features from an idle trunk. This option eliminates the need
to individually enter each feature.
Separate sections cover “DS1 Facilities,” “Tie Trunks,” “DID Trunks,” “PRI
Facilities,” and “BRI Facilities.”
A slot is the physical location of the individual module on the control unit. There
is a maximum of 17 slots which are numbered as follows:
■
Basic carrier: slots 1 through 5
■
First expansion carrier: slots 6 through 11
■
Second expansion carrier: slots 12 through 17
A port is a line or trunk jack on the module. Individual modules support different
numbers of ports. On any module, port 1 is the lowest physical jack position.
Lines connect equipment to the switch and trunks connect a switch to a switch.
Lines and trunks have logical IDs, a unique numeric identifier for each extension
and trunk jack in the communications system control unit. Lines are numbered
from 1 to 144, while trunks are numbered from 801 to 880. An MLX extension
port has 2 logical IDs per 1 physical jack.
