Fax / Modem Transparent With Events Mode; Fax / Modem Transparent Mode - AudioCodes Mediant 2000 User Manual

SIP User's Manual
To configure NSE mode, perform the following configurations:

IsFaxUsed = 0

FaxTransportMode = 2

NSEMode = 1

NSEPayloadType = 100

V21ModemTransportType = 2

V22ModemTransportType = 2

V23ModemTransportType = 2

V32ModemTransportType = 2

V34ModemTransportType = 2

BellModemTransportType = 2

12.2.2.6 Fax / Modem Transparent with Events Mode

In this mode, fax and modem signals are transferred using the current voice coder with the
following automatic adaptations:

Echo Canceller = on (or off, for modems)

Echo Canceller Non-Linear Processor Mode = off

Jitter buffering optimizations
To configure fax / modem transparent with events mode, perform the following
configurations:

IsFaxUsed = 0

FaxTransportMode = 3

V21ModemTransportType = 3

V22ModemTransportType = 3

V23ModemTransportType = 3

V32ModemTransportType = 3

V34ModemTransportType = 3

BellModemTransportType = 3

12.2.2.7 Fax / Modem Transparent Mode

In this mode, fax and modem signals are transferred using the current voice coder without
notifications to the user and without automatic adaptations. It's possible to use the Profiles
mechanism (see ''Coders and Profile Definitions'' on page 199) to apply certain adaptations
to the channel used for fax / modem (e.g., to use the coder G.711, to set the jitter buffer
optimization factor to 13, and to enable echo cancellation for fax and disable it for modem).
To configure fax / modem transparent mode, use the following parameters:

IsFaxUsed = 0

FaxTransportMode = 0

V21ModemTransportType = 0

V22ModemTransportType = 0

V23ModemTransportType = 0

V32ModemTransportType = 0

V34ModemTransportType = 0

BellModemTransportType = 0
