Using Auto Discover for Initial System Configuration 97
Extension
Number The extension number assigned to this port during the Auto Discover
process, or assigned manually. See an example of how to modify the
extension number of a Line Card Port immediately after this table.
Silence
Suppression Specifies whether this port operates under the control of
system-wide Silence Suppression settings. Enable Silence Suppression
only when you have bandwidth constraints and you need to reduce
network traffic. Enabling Silence Suppression results in lower quality
audio. See the
NBX Administrator’s Guide for more information.
The system-wide default setting (On or Off) is marked as the default
setting in the pull-down list. If you want to override the system-wide
default for this port, select the non-default setting from the list.
Trunk to
Trunk Refers to an incoming call being transferred to an outside line.
Although Trunk to Trunk
permission can be granted to individual
users through a Class of Service setting, setting the permission at
each line card port provides a system-level mechanism to enable or
disable this feature.
From the pull-down list, select Restricted (the default) or Unrestricted.
Disable
Caller ID Disables inbound Caller Identification for this line card port. This also
eliminates the Caller ID Wait Timer (6 seconds by default) for picking
up incoming Auto Attendant calls.
Pulse Dialing Sets the default mode of operation for this port. Pulse dialing, also
called Rotary or Decadic dialling, dates to rotary dial telephone
technology. You would enable pulse dialing only in isolated instances
to be compatible with older CO equipment. This setting overrides the
system-wide setting (System Configuration > System Settings >
System-wide).
Values: On, Off, Default
AutoExt AutoExt works in conjunction with telephone button mappings to
define where incoming calls ring. If the line is mapped to a
telephone, it rings at that telephone first. If the Time Out period is
reached, the incoming call rings at the auto extension specified for the
Time of Day service mode (Open, Closed, Lunch, or Other).
Using the AutoExt is one way to route incoming calls to a TAPI Route
Point for call center operations.
Time Out The number of seconds that must pass before the incoming call rings
at the specified auto extension.
This time must be 7 seconds or longer for the system to capture
Caller ID.
Bandwidth Considerations settings allow you to change the amount of bandwidth
used by this port. 3Com recommends that you use default values and change these
settings only when you have bandwidth constraint issues that you cannot solve by
other measures.
