Speech
Directs call control software to request a Speech circuit
as the bearer capability for outgoing calls. Use with

voice service is less expensive than data service. A
Speech call type does not guarantee an end-to-end
digital connection with some local and long distance
carriers.

dio circuit as the bearer capability for outgoing calls.

to-end digital connection with some local and long
distance carriers.
Data 56kbps Directs call control software to request a 6 4kbps data
circuit that is rate-adapted down to 56 kbps.
Data 64kbps Instructs call control software to request an unrestrict-
ed 64 kbps data circuit. (Default for the Express 3100.)
