Assigning Trunk/line data 251
Programming Operations Guide
Answer
mode Manual
Auto
Define whether a trunk is manual or automatic answer.
Auto answer mode allows the trunk to be a shared resource by the system
telephones.
For auto answer trunks being used to allow remote call-in from system users, the
trunk can be configured to answer with a straight dial tone, if DISA has not been
enabled. It can also be configured to answer with a stuttered dial tone if DISA is
enabled and the caller is expected to enter a COS password. The COS password
defines which system features the caller is permitted to access.
Manual answer trunks are assigned to one or more telephones. The assigned
telephones exclusively own the line.
Note: You require Disconnect supervision on the line if loop start trunks are to
operate in auto-answer mode (Trunk mode).
Answer with
DISA Y or N If Y, when a remote user calls into the system on an unsupervised line, the system
prompts a caller for a six-digit class of service (COS) password.
If N, when a remote user calls into the system on an unsupervised line, the call is
connected as dialed.
Link at CO Y or N Some exchanges respond to a Link signal ( FEATURE 71 ) by providing an
alternative line for making outgoing calls.
Enabling Link at CO causes the system to apply the restrictions on outgoing calls to
the digits dialed after the Link signal. As well, the call on the alternative line is
subject to all restrictions.
Disabling Link at CO prevents a Link signal from resetting the Business
Communications Manager restrictions in cases where the host exchange does not
provide an alternative line.
You also need to ensure that telephones using the line have the feature allowed.
Refer to
“Defining telephone dialing restrictions” on page 453 .
Use auxiliary
ringer Y or N Turn the auxiliary ringer on or off for all telephones using this line.
When programmed on a line, the auxiliary ringer will ring every time a call is
received.
Note: When programmed only on a telephone, no ring occurs for a transferred call.
An auxiliary ringer can also be programmed in Services to ring for a line placed into
a scheduled Ringing service. Refer to
“Configuring ringing service” on page 496
Full autohold Y or N Enables or disables Full autohold.
When enabled, if a caller selects an idle line but does not dial any digits, that line is
automatically placed on hold if you then select another line.
The default setting should be changed only if Full autohold is required for a specific
application.

Select the appropriate loss/gain and impedance settings for each line.
For more information refer to “Using loss packages” on page 272 .
Impedance 600 ohm
900 ohm
The GATM can be set to a specific impedance level. This is determined by local
line requirements.
