Determining Line Access Dialing; Figure 91 Line Management Diagram - Nortel BCM 3.7 Manual

Determining line access dialing

The next two sections,
on page 331 describe what you do with the lines and loops you previously set up into line pools.
By using access codes or call routing, which uses destination codes, you can determine which lines
(routes) outgoing calls use. When you create a route, you can also specify restrictions that apply to
how or when the line will be used.
The following figure provides an overview of how access codes and routing is used within the
system to direct calls from a telephone in one system to a telephone in another system.
