Generalized route selection
Generalized Route Selection (GRS) is built into Automatic Alternate Routing
(AAR) and Automatic Route Selection (ARS). This switch uses GRS to look at
various route patterns and preferences and decide which preference is most
appropriate at the time. With GRS, voice and data calls can be sent along separate
routes or be integrated on the same trunk group. If the type of transmission is
incompatible with the endpoint (for example, a digital data call is sent to an
analog phone), GRS provides a conversion resource such as a modem from a
modem pool to complete the call.
