MP-26x/MP-27x Multimedia Home Gateway
Parameter Description
Max Rate
Defines the maximum fax rate.
2.4 Kbps, 4.8 Kbps, 7.2 Kbps, 9.6 Kbps, 12 Kbps or 14.4 Kbps (default).
Note: This parameter appears only if 'Fax Transport Mode' is set to ‘T.38
Relay’.
Max Buffer Defines the maximum amount of T.38 data stored on the devices. The valid
range is 128 to 2048. The default is 1024.
Note: This parameter appears only if 'Fax Transport Mode' is set to ‘T.38
Relay’.
Max Datagram Defines the maximum total size of TCP/UDPTL packets that can be
received at the remote gateway. The valid range is 160 to 1020. The
default is 320.
Note: This parameter appears only if 'Fax Transport Mode' is set to ‘T.38
Relay’.
Image Data
Redundancy Level Defines the level for output Image Data (2400…14400 bps).

0 = No redundancy

1 to 3 = Redundancy level
Note: This parameter appears only if 'Fax Transport Mode' is set to ‘T.38
Relay’.
T30 Control Data
Redundancy Level
Defines the redundancy level for output T.30 Control Data (300 bps).

0 = No redundancy

1 to 7 = Redundancy level
Note: This parameter appears only if 'Fax Transport Mode' is set to ‘T.38
Relay’.
Fax Relay Jitter Buffer
Delay Defines the Fax Relay Jitter Buffer.

0 = Adaptive Jitter Buffer. The device sets the Jitter Buffer size
automatically and then adapts it according to network conditions.

1 to 511 = Fixed Jitter Buffer size (in msec).
Note: This parameter appears only if 'Fax Transport Mode' is set to ‘T.38
Relay’.
Error Correction Mode Enables (default) fax error correction mode (ECM).
Note: This parameter appears only if 'Fax Transport Mode' is set to ‘T.38
Relay’.
Fax Bypass Payload
Type Defines the payload type for fax in Bypass mode.
Note: This parameter appears only if 'Fax Transport Mode' is set to
‘Bypass’.
Modem Transport
Mode Selects the way modem calls are handled:

Transparent = Data is transferred in-band (like a voice call). This can be
used if the codec is G.711.

Voice Band Data = Switch to G.711 via SIP messaging.

Bypass = An automatic switch to AudioCodes' proprietary payload type
(102, 103).
Note: If the Fax transport mode is Bypass or VBD, it must match the
Modem transport mode.
Modem Bypass
Payload Type Defines the payload type for modems in Bypass mode.
Note: This parameter appears only if 'Modem Transport Mode' is set
‘Bypass’.
