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.
NOTE:
Even if the trunk group supports full-duplex transmission, other equipment in a circuit
may not.
End-to-End Signaling
Auxiliary equipment such as paging equipment and music sources may be connected to Avaya
Communication Manager by auxiliary trunks. Communication Manager may send DTMF signals (touch
tones) to these devices. This field, which appears when the
Group Type
field is 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.
Expected Digits
NOTE:
Set this field to blank if the Digit Treatment field is set to insert and the Digits field
contains a feature access code (for example, AAR or ARS) followed by digits. In this case,
the number of digits expected are set on the AAR and ARS Digit Analysis Table and AAR
and ARS Digit Conversion Table.
Valid entries
Usage
full Enter
full in most cases: this allows simultaneous two-way
transmission, which is most efficient.
half
Enter half to support only one transmission direction at a time.
Valid entries
Usage
60 to 360 ms in
increments of
10
Use this field to set the duration in milliseconds of the touch-tone
signal that is sent to the connected equipment.
Valid entries
Usage
1 to 18
Enter the number of digits that the far-end media server or switch
sends for an incoming connection. If your end is absorbing digits on
this trunk group, the entry in this field must be larger than the entry
in the Digits field.
If you leave this field blank, you cannot administer digit absorption.
