Mediant 800B Gateway and E- SBC
Description
payload is retransmitted to the network.

[0] = (Default) No redundancy

[1] = One packet redundancy

[2] = Two packet redundancy
Note: The parameter is applicable only to non-
V.21 packets.
Defines the maximum rate (in bps) at which fax
relay messages are transmitted (outgoing calls).

[0] 2400 = 2.4 kbps

[1] 4800 = 4.8 kbps

[2] 7200 = 7.2 kbps

[3] 9600 = 9.6 kbps

[4] 12000 = 12.0 kbps

[5] 14400 = 14.4 kbps (default)

[6] 16800bps = 16.8 kbps

[7] 19200bps = 19.2 kbps

[8] 21600bps = 21.6 kbps

[9] 24000bps = 24 kbps

[10] 26400bps = 26.4 kbps

[11] 28800bps = 28.8 kbps

[12] 31200bps = 31.2 kbps

[13] 33600bps = 33.6 kbps
Notes:

The rate is negotiated between both sides
(i.e., the device adapts to the capabilities of
the remote side). Negotiation of the T.38
maximum supported fax data rate is provided
in SIP's SDP T38MaxBitRate parameter. The
negotiated T38MaxBitRate is the minimum
rate supported between the local and remote
endpoints.

Fax relay rates greater than 14.4 kbps are
applicable only to V.34 / T.38 fax relay. For
non-T.38 V.34 supporting devices,
configuration greater than 14.4 kbps is
truncated to 14.4 kbps.
Enables Error Correction Mode (ECM) mode
during fax relay.

[0] Disable

[1] Enable (default)
Determines the coder used by the device when
performing fax/modem bypass. Typically, high-
bit-rate coders such as G.711 should be used.

[0] G.711Alaw= (Default) G.711 A-law 64
[1] G.711Mulaw = G.711 µ-law

Defines the number (20 msec) of coder payloads
used to generate a fax/modem bypass packet.
The valid range is 1, 2, or 3 coder payloads. The
default is 1 coder payload.
