Chapter 6 Module configuration: Trunk modules 83
Networking Configuration Guide
Configuring the trunk module parameters
Modules automatically configure to a free bus when they are connected to the system.
• That bus determines what line numbers are supported by the module.
• Module programming determines the type of line.
• Trunk configuration determines the line properties for the system.
To define the modules to the system
1 On the Modules panel, click the trunk module entry that you want to view.
2 On the Module Parameters tab panel, review the settings to ensure they support the type of line
function provided from the Central Office (CO). For details of the configurable parameters for
a trunk type, refer to “Module parameters list” on page 83.
3 If your module supports T1, PRI, or DASS2, refer to “Call-by-Call Service Selection” on
page 108 and “Provisioning module lines/loops” on page 112.
If your module supports other types of trunks, configure each line record. Refer to
“Configuring lines” on page 129.
Module parameters list
The following contains information about the module parameters that are specific to a module
type.
Refer to “Trunk Module Parameters” on page 104 for detailed field descriptions.
Configuring digital and analog loop module parameters
• Module mode: The mode for the type of line being supported (DS/CLID, Global, Legacy).
• Disconnect Timer: Enter the time delay for disconnect supervision for lines supplying
supervised external lines. This setting must match the CO setting.
Configuring DTM-T1/E1 module parameters
• Clock Source: Determine how the module functions for timing on the network (Primary
External, Secondary External, Internal).
