Table 5-33: Media Settings -- Fax/Modem/CID Parameters
Parameter Description
V.34 Modem Transport Type
[V34ModemTransportType]
V.90 / V.34 Modem Transport Type that the gateway uses.
 [0] Disable = Disable (Transparent)
 [1] Enable Relay = N/A
 [2] Enable Bypass = (default)
 [3] Events Only = Transparent with Events
Fax Relay Redundancy Depth
[FaxRelayRedundancyDepth
]
Number of times that each fax relay payload is retransmitted to the
network. This parameter is applicable only to non-V.21 packets.
The valid range is 0 to 2, where 0 is no redundancy, 1 is one packet
redundancy, and 2 is two packet redundancy.
The default value is 0.
Fax Relay Enhanced
Redundancy Depth
[FaxRelayEnhancedRedunda
ncyDepth]
Number of times that control packets are retransmitted when using
the T.38 standard.
The valid range is 0 to 4. The default value is 0.
Fax Relay ECM Enable
[FaxRelayECMEnable]
 [0] Disable = Error Correction Mode (ECM) mode is not used
during fax relay.
 [1] Enable = ECM mode is used during fax relay (default).
Fax Relay Max Rate (bps)
[FaxRelayMaxRate]
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).
Note: The rate is negotiated between the sides, i.e., the gateway
adapts to the capabilities of the remote side.
Fax/Modem Bypass Coder
Type
[FaxModemBypassCoderTyp
e]
Coder the gateway uses when performing fax/modem bypass.
Usually, high-bit-rate coders such as G.711 should be used.
 [0] G.711Alaw= G.711 A-law 64 (default).
 [1] G.711Mulaw = G.711 µ-law.
Fax/Modem Bypass Packing
Factor
[FaxModemBypassM]
Number of (20 msec) coder payloads that are used to generate a
fax/modem bypass packet.
The valid range is 1, 2 or 3 coder payloads.
The default value is 1 coder payload.
