carrier
The device supports two fax protocols: T.38 protocol and standard T.38 protocol.
The standard fax protocol should be selected for interworking with leading fax
terminals in the industry. Since most of leading fax terminals in the industry do not
support the local training mode, the ppp training mode must be selected for
interworking with these leading devices in the industry.
