Configuring lines
This section describes the information accessed under the Services, Telephony Services , Lines
headings.
This section contains:
• “Understanding the process of line configuration” on page 240
• “Understanding how the system identifies lines” on page 241
• “Using the General record” on page 247
• “Assigning Trunk/line data” on page 248
• “Assigning Restrictions” on page 273
• “Setting line telco features” on page 275
The screens accessed through these headings define the line numbers that correspond to the DIP
switch settings that were configured on the trunk media bay modules installed on your system.
Check your Programming Record to see which modules are installed, and what settings were
chosen. The screens also are used to assign Voice over IP (VoIP) trunks and target line
s , however,
the process for defining these lines is described in other sections since they are not related directly
to external hardware.
Note: External lines are also referred to as trunks. External lines include the lines between the
public network (PSTN) and between the nodes in a private network. Non-physical connections,
such as voice over IP (VoIP) and target lines, are also referred to as trunks and lines, respectively,
even though they do not describe actual wired connections.
All physical trunks connect to the Business Communications Manager through a media bay
module of some sort. All non-physical trunks and lines use a LAN or WAN connection (VoIP
trunks) or internal call processing (target lines).
However, the connection, all lines are configured under the Lines or loops headings.
Other configuration options or requirements:
• BRI loops require configuration and provisioning before the BRI lines can be configured.
Refer to Chapter 10, “Configuring BRI Loops,” on page 277 .
• The Business Communications Manager also offers facilities for splitting trunks to deliver
both data and telephony services. Refer to the chapter titled “Data and split-line configuration”
on page 161 for a description of how the Business Communications Manager uses data
modules and WAN programming in this context.
Task:
• Configure the lines connected to the system, or call channels configured as Voice over IP
(VoIP) trunks or target lines.
