Physical lines

Physical lines are the central office (CO) trunks assigned to the trunk media bay modules. See the

Installation and Maintenance Guide (NN40020-302) for information about which lines are

enabled.

You can change the line types to suit your system. For instance, BRI and DTM modules can be

designated to a number of line types, depending on the type of line service provided through the

central office (CO). However, the line numbers are associated for specific tasks or to specific

DS30 bus numbers.

The line record allows you to program settings for lines that affect how the lines operate in the

network and with other switches, as well as how the system uses the line.

Trunk types:

•VoIP

• DTM (digital): TI types (Loop, E&M, DID, Ground, or fixed data channel), PRI, DASS2,

DPNSS.

• CTM (North America)/GATM: Analog Loop

• BRI: BRI S/T

• Target lines

BRI loops programming

The Loops panels define the loop numbers and loop attributes that correspond to the DIP switch

settings that were configured on the BRI trunk media bay modules installed on your system. Check

your Programming Record to see which modules are installed, and what settings were chosen.

Available BRI trunk loop attributes are determined by the country profile that is assigned to your

system. All profiles allow BRI programming; however, there is a difference between T1-based

profiles and for E1-based profiles.

Once loops are provisioned, the system assigns two line numbers per loop. These lines are then

programmed as you would any other lines.

You can program a loop to support either trunking services to the ISDN network, or terminal

services to one or more ISDN devices. The following sections describe the programming for each

type of loop. For complete module installation instructions and safety precautions, see the

Installation and Maintenance Guide (NN40020-302).
