Valid Range and Description
NSEMode
Cisco compatible fax and modem bypass mode
0 = NSE disabled (default)
1 = NSE enabled
Note 1: This feature can be used only if VxxModemTransportType=2
(Bypass)
Note 2: To use this feature:
 The Cisco gateway must include the following definition: ‘modem
passthrough nse payload-type 100 codec g711alaw’.
 Set the Modem transport type to Bypass mode
(‘VxxModemTransportType = 2’) for all modems.
 Configure the gateway parameter NSEPayloadType= 100
In NSE bypass mode the gateway starts using G.711 A-Law (default) or
G.711µ-Law, according to the parameter ‘FaxModemBypassCoderType’.
The payload type used with these G.711 coders is a standard one (8 for
G.711 A-Law and 0 for G.711 µ-Law). The parameters defining payload type
for the ‘old' AudioCodes’ Bypass mode. ‘FaxBypassPayloadType’ and
‘ModemBypassPayloadType’ are not used with NSE Bypass. The bypass
packet interval is selected according to the parameter
‘FaxModemBypassBasicRtpPacketInterval’.
NSEPayloadType
NSE payload type for Cisco Bypass compatible mode.
The valid range is 96-127. The default value is 105.
Note: Cisco gateways usually use NSE payload type of 100.

EchoCancellerAggressiveNLP
Enables or disables the Aggressive Non-Linear Processor (NLP) in the first
0.5 second of the call.
0 = Disabled (default)
1 = Enabled
EnableNoiseReduction
Enables / disables the DSP Noise Reduction mechanism.
0 = Disable (default).
1 = Enable.
Note: When this parameter is enabled the channel capacity might be
reduced.
TestMode
0 = CoderLoopback, encoder-decoder loopback inside DSP.
1 = PCMLoopback, loopback the incoming PCM to the outgoing PCM.
2 = ToneInjection, generates a 1000 Hz tone to outgoing PCM.
3 = NoLoopback, (default).
