Mediant 500L Gateway & E-SBC
Parameter Description
 V34ModemTransportType
 [0] Disable = Transparent.
 [2] Enable Bypass (Default)
 [3] Events Only = Transparent with Events.
For a detailed description of the parameter per modem type, see the
relevant global parameter (listed above).
NSE Mode
nse-mode
[IpProfile_NSEMode]
Enables Cisco's compatible fax and modem bypass mode, Named
Signaling Event (NSE) packets.
 [0] Disable (Default)
 [1] Enable
In NSE bypass mode, the device starts using G.711 A-Law (default) or
G.711-Law, according to the FaxModemBypassCoderType
parameter. The payload type for these G.711 coders is a standard one
(8 for G.711 A-Law and 0 for G.711 -Law). The parameters defining
payload type for the 'old' Bypass mode FaxBypassPayloadType and
ModemBypassPayloadType are not used with NSE Bypass. The
bypass packet interval is configured according to the
FaxModemBypassBasicRtpPacketInterval parameter.
The SDP contains the following line:
'a=rtpmap:100 X-NSE/8000'.
Note:
 When enabled, the following conditions must also be met:

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 is set to 2) for all modems.

Set the NSEPayloadType parameter to 100.
 The corresponding global parameter is NSEMode.
Gateway Answering Machine
AMD Sensitivity Parameter
Suite
amd-sensitivity-parameter-
suit
[IpProfile_AMDSensitivityPar
ameterSuit]
Defines the AMD Parameter Suite to use for the Answering Machine
Detection (AMD) feature.
 [0] 0 = (Default) Parameter Suite 0 based on North American
English with standard detection sensitivity resolution (8 sensitivity
levels, from 0 to 7). This AMD Parameter Suite is provided by the
AMD Sensitivity file, which is shipped pre-installed on the device.
 [1] 1 = Parameter Suite based 1 on North American English with
high detection sensitivity resolution (16 sensitivity levels, from 0 to
15). This AMD Parameter Suite is provided by the AMD Sensitivity
file, which is shipped pre-installed on the device.
 [2] 2 to [7]7 = Optional Parameter Suites that you can create based
on any language (16 sensitivity levels, from 0 to 15). This requires
a customized AMD Sensitivity file that needs to be installed on the
device. For more information, contact your AudioCodes sales
representative.
Note:
 To configure the detection sensitivity level, use the 'AMD Sensitivity
Level' parameter.
 For more information on the AMD feature, see Answering Machine
Detection (AMD) on page 210.
