CHAPTER 60 Configuration Parameters Reference
Mediant 4000 SBC | User's Manual
Parameter Description
■ [1] = Enable. When the parameter is
enabled on Bypass and transparent
with events mode
(VxxTransportType is set to 2 or 3), a
detection of an Answer Tone from the
network triggers a switch to bypass
mode in addition to the local
Fax/Modem tone detections.
However, only a high bit-rate coder
voice session effectively detects the
Answer Tone sent by a remote
endpoint. This can be useful when,
for example, the payload of voice and
bypass is the same, allowing the
originator to switch to bypass mode
as well.
NSE-mode
[NSEMode]
Global parameter that enables Cisco's
compatible fax and modem bypass
mode, Named Signaling Event (NSE)
packets. You can also configure this
feature per specific calls, using IP
Profiles (IpProfile_NSEMode). For a
detailed description of the parameter and
for configuring this feature in the IP
Profiles table, see
Configuring IP
Profiles .
Note: If this feature is configured for a
specific IP Profile, the settings of this
global parameter is ignored for calls
associated with the IP Profile.
NSE-payload-type
[NSEPayloadType]
Defines the NSE payload type for Cisco
Bypass compatible mode.
The valid range is 96-127. The default is
105.
Note: Cisco gateways usually use NSE
payload type of 100.
'T.38 Max Datagram Size'
configure voip > sip-definition
settings > t38-mx-datagram-sz
[T38MaxDatagramSize]
Defines the maximum size of a T.38
datagram that the device can receive.
This value is included in the outgoing
SDP when T.38 is used.
The valid range is 120 to 600. The default
is .
'Detect Fax on Answer Tone'
det-fax-on-ans-tone
[DetFaxOnAnswerTone]
Determines when the device initiates a
T.38 session for fax transmission.
