P0886634 Issue 1.0 FAX Installation Guide
DFC overview
The Digital Fax Card (DFC) is installed in an expansion bus slot on the Norstar
Application Module (NAM) and supports four Fax Channels.
There are no Time Compression Multiplexing (TCM) connections to the DFC. The
DFC uses the Voice Channels on the Digital Voice Cards (DVCs) or BIC to connect
the Fax Channels to fax machines or a call.
Note: When Norstar Voice Mail FAX is using a Voice Channel to connect to the
fax machine or a caller, that Voice Channel cannot be used by other users
until the FAX function is complete.
