Issue 1
April 2000
Subnet Trunking
Modifies the number you dial so an AAR or ARS call can route over different trunk groups
that may terminate in switches with different dial plans. Subnet Trunking inserts digits,
deletes digits, pauses, and/or waits for dial tone in digit outpulsing, as required, so calls
route:
■ To or through a remote switch
■ Over Tie trunks to a private network switch
■ Over CO trunks to the serving CO
Subnet Trunking is required on calls routing to or through a remote switch, regardless of
the call’s destination.
Extension Number Portability
Gives you the ability to assign any extension to any system in a subnetwork. Stations can
be moved across systems while retaining the original extension number, as long as the
systems are part of a defined subnetwork. This feature is used in conjunction with
Automatic Alternate Routing and Uniform Dial Plan.
Alarm Assignments
Alternate Operations Support System Alarm
Number
Allows you to establish a second number for the DEFINITY ECS to call when an
alarmable event occurs. This feature is useful for alerting a second support organization,
such as INADS or OneVision.
External Device Alarming
Allows you to assign analog ports to alarm interfaces for external devices. You can
specify a port location, information to identify the external device, and the alarm level to
report when a contact closure occurs.
