Chapter 1 Cisco Analog Telephone Adaptor Overview
Installation and Configuration Overview
Fax Services
The Cisco ATA supports two modes of fax services, in which fax signals are transmitted using the G.711
codec:
•
Fax pass-through mode—Receiver-side Called Station Identification (CED) tone detection with
automatic G.711A-law or G.711µ-law switching.
•
Fax mode—The Cisco ATA is configured as a G.711-only device.
How you set Cisco ATA fax parameters depends on what network gateways are being used. You may
need to modify the default fax parameter values (see
Chapter 7, “Configuring and Debugging Fax
Services”
).
Note
Success of fax transmission depends on network conditions and fax modem response to these conditions.
The network must have reasonably low network jitter, network delay, and packet loss rate.
