Coordination with the main office call server

Configuration of the SRG branch office requires datafill at both the SRG and the main office call
server. Main office configuration drives SRG configuration, and Nortel recommends that the main
office activities be concluded before undertaking SRG configuration.

SRG operating modes

The SRG has two operating modes:
•

Normal mode

• Local mode

call server over a WAN using VoIP trunks. From the perspective of the main office, the SRG is a
branch office.
Description
Target lines are internal, virtual paths between trunks and telephones for incoming calls
(only). They provide flexibility in the way trunks and telephones can be associated: target
lines can be used to direct an incoming call to one or more telephones, direct one or
more trunks to one phone, or direct several trunks (in a line pool) to one or more phones.
Target lines are assigned to DNs. A target line triggers ringing voltage to the telephone(s)
connected to the port(s) associated with the DN(s) that the target line is assigned to. (For
example, if a unique target line is assigned to each DN, only one telephone rings when
the DN is called. If several DNs are assigned to one target line, calling any of the DNs
ring all of the associated phones.)
Target lines are required for auto-answer trunks. Because VoIP lines are set internally to
auto-answer, target lines are required for SRG operation.
Element Manager provides two methods for assigning target lines to DNs.
1) Configuration > Telephony > Sets > All DNs > All DNs table > Details for DN subpanel
> Line Assignment tab
or
2) Configuration > Telephony > Lines > Target Lines > Target Lines table > Details for
Line subpanel > Assigned DNs tab
The first method provides a convenient way to assign the target line to the DN when the
DN record is configured. The second method provides fields that allow incoming digit
strings to be mapped to the DN.
