.
This field appears when the “out” side of the entry in the Trunk Type (in/out) field
is
…/wink or …/delay and the Group Type is tie, access, aplt, dmi-bos, rlt, or
tandem. The setting in this field only affects trunks administered to ports on
TN760C (vintage 4 or later), TN767, TN464C (or later), and TN2242 circuit
packs. If the trunk group also contains trunks assigned to ports on other types of
circuit packs, those trunks are unaffected.
Trunk Termination
This field adjusts the impedance of the trunk group for optimal transmission
quality. Check with your service provider if you’re not sure of the distance to your
central office.
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.
Setting of the Trunk
Type (in/out) field What the Wink Timer field sets
…/wink
Maximum duration of the wink signal
(wait-for-wink-to-end)
…/delay
Maximum interval after trunk seizure for the wink to
begin (wait-for-wink-to-start)
Valid entries Usage
300
to 5000 in
increments of
50
In general, Lucent recommends that you not change this field.
If you do, remember that your switch’s timing must be
compatible with the timing on the far-end switch.
Valid entries Usage
600ohm
Enter 600ohm when the distance to the central office or the
switch at the other end of the trunk is less than 3,000 feet.
rc Enter rc when the distance to the central office or the switch at
the other end of the trunk is more than 3,000 feet.
Valid entries Usage
140
to 2550 ms
in increments of
10
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.
