Tips: External lines and telephones must be programmed to use one of the Scheduled
Services: Ringing, Restriction, and Routing Services.
For maximum flexibility, Nortel recommends that you create two different control
telephones, one for the lines and one for the telephones.
You can turn on a service manually or automatically for all external lines from an assigned
control telephone. However, you cannot combine schedules. A service can only be active
as normal service or one of the six schedules at any one time. Several schedules can be
active at one time, but they must use different services.

Description
There are three main categories of lines:
PSTN-based lines: (analog, T1, PRI, BRI)
Voice over IP (VoIP) trunks, which connect through the LAN
or WAN.
Target lines, which are internal channels that provide direct
dial capability.
Identify the line in a way that is meaningful to your system,
such as by the type of line and line pool or the DN it is
attached to in the case of target lines.
Enter a telephone DN for a telephone that you want to use
to turn service off or on for other telephones using this line.
The control telephone must have the line assigned, or must
be assigned to the line pool the line is in.
Define how the line is used in relation to other lines in the
system.
• Public line: can be accessed by more than one
telephone.
• Private line: can be assigned only to one telephone and
the prime telephone for that line. Enter the internal
number of the telephone.
• Pool A - O (analog and T1 lines) BlocA to BlocF
(PRI and VoIP lines): assigns the line to one of the line
pools. If a line is assigned to a line pool, but is not
assigned to any telephone, that line is available only for
outgoing calls.
Bloc line pools must be used in conjunction with routes
and destination codes. Target lines cannot be put into
line pools.
Assign a telephone to provide backup answering for calls
on the line. For an Auto Answer line, calls are redirected if
the received number is invalid or the target line is busy, and
if the
If busy parameter is set To prime.
Each line can be assigned only one prime telephone.
