configured for voice service. In some areas, voice service costs
less than data services. A speech call type does not always
guarantee an end-to-end digital connection with some local
and long distance carriers.
Audio - Audio directs the call control software to request a
3.1 kHz audio circuit as the bearer capability for the outgoing
calls. The audio option is used with an ISDN line configured for
voice service. In some areas, audio service costs less than data
services. An audio call type does guarantee a digital end-to-end
digital connection.
56K - 56K directs the call control software to request a 64 kbps
data circuit that is rate-adapted to 56 kbps. Data 56 kbps is
intended for use in circumstances where interoperability with
Switched 56 service is desired.
64K (def) - The default call type for ISDN service is Data 64 kbps.
This directs the call control software to request an unrestricted
64 kbps circuit.
