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 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.
