Brief description
Call-by-Call Service Selection uses the same route patterns and route preferences
that are used by Automatic Alternate Routing (AAR), Automatic Route Selection
(ARS), and Generalize Route Selection (GRS). The service or facility used on an
outgoing Call-by-Call Service Selection call is determined by information
assigned in the AAR/ARS/GRS route patterns.

You can allow a variety of services to use a single trunk group. The system obtains
trunking efficiency by distributing traffic over all the available trunks. Then you
can assign services that are used on incoming and outgoing Call-by-Call Service
Selection calls. The system provides traffic measurements for each individual
service administered for an ISDN Call-by-Call Service Selection trunk group.
