Hop Dgt — The Tandem Hop Limitation and QSIG Additional Network Feature Transit
●
Counter (ANF-TC) features provide a counter that reflects the number of switches (that is,
the number of hops) that a call has gone through. The counter increments as a call leaves
Avaya Communication Manager using tandem facilities. Valid values are y and n. One or
both of the features can be applied to the trunk group depending on the following:
- If you enter y and the Group Type field is tandem or the Group Type field is isdn and
the Service Type field is tandem, the Tandem Hop Limitation feature is applied to the
trunk group.
- If you enter y and you set the Group Type field to isdn, set the Service Type field to
access, dmi-mos, public-ntwrk, tandem, tie, or any of the craft-defined services
allowed in the field. Set the Supplementary Service Protocol field to b or d, then the
ANF-TC feature is applied to calls on the trunk group.
Note:
The above conditions overlap. If the Group Type field is isdn, the Service Type
Note:
field is tandem, and the Supplementary Service Protocol field is b or d, then
both the Tandem Hop Limitation and ANF-TC features are applied to calls on the
trunk group.
- If both features are applied to calls on the trunk group, ANF-TC takes precedence. In
situations where Avaya Communication Manager serves as an Incoming or Outgoing
Gateway, either feature uses the hop count and transit information provided by the other.
