Coordination with the main office call server
Configuration of the SRG50 branch office requires datafill at both the SRG50 and the main office
call server. Main office configuration drives SRG50 configuration, and Nortel recommends that
the main office activities be concluded before undertaking SRG50 configuration.
VoIP Lines
VoIP trunks.
EM: Configuration > Telephony > Lines > Active VoIP Lines
(Lines 001 to 024)
Target Lines
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.
The SRG50 Element Manager provides two methods for assigning target lines to DNs.
1)
EM: Configuration > Telephony > Sets > All DNs > All DNs
table
> Details for DN
subpanel
> Line Assignment
tab
or
2)
EM: 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.
(Lines 125 to 268)
For more information on target lines, refer to the
BCM50 Networking Configuration Guide
(N0027156).
Line pool
Several of the same type of trunk configured as one group: a trunk group.
Note:
Configuration activities at the SRG50 that are unique to a specific type
of main office call server are covered in separate chapters in this guide.
