End-to-End Signaling
Auxiliary equipment such as paging equipment and music sources may be
connected to DEFINITY ECS by auxiliary trunks. The switch may send DTMF
signals (touch tones) to these devices. This field, which appears for CPE
(customer-provided equipment) trunk groups, sets the duration of these tones.
NOTE:
For trunks that do not receive real answer supervision, a “connect” Event
report is sent when the Answer Supervision Timeout occurs.
Analog Gain
Use this field to reduce the strength of incoming signals on TN2199 ports if users
regularly experience echo, distortion, or unpleasantly loud volume. Experiment to
find the best setting for your situation. This field appears if the Country field is
15
and the Trunk Type (in/out) field is
2-wire-ac, 2-wire-dc, or 3-wire.
Digit Treatment
Use this field to modify an incoming digit string (as on DID and tie trunks, for
example) by adding or deleting digits. You’ll need to do this if the number of
digits you receive doesn’t match your dial plan.
If you enter absorption or insertion, then you must enter a value in the Digits field.
