Trunk Group
Issue 5 October 2002 1247555-233-506
Disconnect Timing (msec)
This field specifies the minimum time in milliseconds that the central office or
far-end switch requires to recognize that your switch has disconnected from a call.
This timer does not affect ports on a circuit pack that uses the administrable
Incoming Disconnect and Outgoing Disconnect timers; in fact, settings on those
two timers override this field.
Disconnect Type
This field indicates which side or user controls the disconnect, where A refers to
the calling party and B refers to the called party. Appears only if the Country field
is
15 and the Trunk Type field is 2-wire-ac, 2-wire-dc, or 3-wire.
This applies only to the TN2199 port.
Drop Treatment
This field only applies to DID trunks. It determines what the calling party hears
when the called party terminates an incoming call.
NOTE:
In Italy, the Drop Treatment field must be administered as intercept for all
DID trunk groups.
Duplex
This field specifies whether a two-way trunk group allows simultaneous
transmission in both directions. This field appears when the Comm Type field is
avd or rbavd. It also appears if the Comm Type field is data, but only if the
ISDN-PRI field is enabled on the System-Parameters Customer-Options screen.

The default of 500 is an industry standard and you shouldn’t
change it. If you set this field too high, your switch won’t
disconnect sometimes when it should; too low, and it will
disconnect when it shouldn’t.
