Description
GS E&M
Define whether a trunk is manual or automatic answer.
Auto answer mode allows the trunk to be a shared resource by
the system telephones. This shared resource is created through
routing to target lines or using DISA.
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.
GS E&M
Define whether the system prompts a caller for a six-digit class
of service (CoS) password. This setting appears for T1 loop
start, T1 E&M lines that have auto-answer mode, and analog
trunks. Set this option to No for T1 E&M lines on a private
network that have auto-answer mode.
To program DISA on a PRI trunk you need to specify a DISA
DN, see "Call Security: Configuring Direct Inward System
Access (DISA)" on page 427

Define whether a caller receives a busy tone or the call
forwards to the prime telephone when the target line is busy.
Busy tone only works for PRI trunks.
