Manual

 

Define whether a trunk is manual or automatic answer.

 

Auto

 

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.

 

 

 

 

 

 

 

 

 

 

Note: You require Disconnect supervision on the line if loop start trunks are to

 

operate in auto-answer mode.

<check box>

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.

TL

 

To Prime

 

Define whether a caller receives a busy tone or the call

 

Busy Tone

forwards to the prime telephone when the target line is busy.

 

Busy tone only works for PRI trunks.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Tips: The duration of an open switch interval (OSI) before BCM450 disconnects a

 

call is programmed by the Disconnect timer setting.

<dial string>

Enter a dial string (including destination code) to redirect the

 

 

 

 

line to an external telephone, such as a call attendant on

 

 

 

 

another system.

 

 

 

 

 

 

 

 

 

If you want to stop redirection, you need to delete the dial string

 

 

 

 

and allow the record to update.

 

 

 

 

 

 

 

Warning: If the dialstring is set up, the line will immediately be

 

 

 

 

redirected out of the system not ringing any telephone.
