Check the settings to ensure they reflect the line requirements. Note that only some of the
fields appear for all module types.
Refer to the following table for a description of each field.
Table 12 Module record values
Attribute Value Module/line type
Module mode DS/CLID, Global,
Legacy
Loop
• DS/CLID: displays for old North American LS/DS or CLID analog trunk modules, the old analog
MBM, or the GATM with North American DIP switch settings.
• Global: displays for the GATM MBM with no regional DIP switches set.
• Legacy: displays for all other (old) analog trunk modules
# of lines/
loops <digits>
Loop E&M DID T1 PRI
BRI
S/T
BRI U2 BRI U4
The total number of lines or loops provided by the loops or trunks on this module.
Low/line loop View only
Loop E&M DID T1 PRI
BRI
S/T
BRI U2 BRI U4
The lowest line or loop number assigned by the system to the module based on the Bus
number, module type, and the module position on the Bus (offset on module DIP switch).
High/line loop View only
Loop E&M DID T1 PRI
BRI
S/T
BRI U2 BRI U4
The highest line or loop number assigned by the system to the module based on the Bus
number, module type, and the module position on the Bus (offset on the module DIP
switch).
Disconnect
timer 60, 100, 260, 460,
or 600 milliseconds
Loop T1
Specify the duration of an Open Switch Interval (OSI) before a call on a supervised external
line is considered disconnected. This setting must match the setting for the line at the
central office (CO).
You must enable disconnect supervision by changing the Trunk mode attribute. Under the
Telephony Services sub-heading, choose Lines and Line/trunk Data. See “Assigning Trunk/
line data” on page 248 for more information.
Note: Available to all supported countries for BCM 3.6 and newer software.
Answer timer 1, 2, 3, 4, or 5 sec.
E&M PRI
Set the minimum duration of an answer signal before a call is considered to be answered.
