Carrier Access Multi-Service Router (MSR) Card MSR/Adit 3K GUI - Manual (Page 217)

Adit 3000 (Rel. 1.6) and MSR Card (Rel 2.0) GUI 6-11
Voice over IP
IP Telephony
FXS Signaling
Calling Party
Disconnect (CPD)
Duration Allows the user to configure the disconnect timeout for individual lines. Range is
500 - 3000. Default is 900.
Features
Sylantro Centralized
Conferencing Enables the “Centralized Three-Way Calling” feature with the Sylantro application
server. This provides the means for an FXS telephone user to place an existing SIP
call on hold, dial a second SIP call, then connect all 3 parties together.
Registration - Allows SIP URI registration for each number assiged to an FXS or trunk line.
Number of Registration
per Minute Range 1 - 300. 0 = disabled. Default is 60.
Registration Expires
Timeout Range 30 - 86400 Seconds. Default is 3600 seconds.
Registration Window
Size Range 1 - 304. Default is 10.
Retry Timeout (SIP T1) Range 200 - 4000 milliseconds. Default is 500.
Tries Per Cycle
Range 1 - 10. Default is 2.
Failed Registration
Timer Range is 300 - 86400 seconds. Default is 60.
T.38 Fax-Relay
Note: For the Adit 3000, this feature is available only when the Adit is configured with the FXS option.
Note: For the Adit MSR, T.38 will be supported in a future release.
T.38 Signaling NSE Only - NSE (Named Service Event) will be the only method tried.
NSE Preferred - NSE preferred will be the first method tried, with an attempt to
the alternate SDP method if it fails. Default.
SDP Only - SDP (Session Description Protocol) will be the only method tried.
SDP Preferred - SDP preferred will be the first method tried, with an attempt to
the alternate NSE method if it fails
T.38 Error Detection
Scheme None - Set error correction to none.
Redundancy - A T.38 data stream is transmitted with redundant (duplicated) data
and checksums (CRCs). This way, if the receiving gateway detects that a packet
has been lost or corrupted, it can extract it from the redundant data.
T.38 Redundancy
Note: For the Adit 3000, this feature is available only when the Adit is configured with the FXS option.
Note: For the Adit MSR, T.38 will be supported in a future release.
Ls Redundancy Range 0 to 8 packets (0 = no redundancy), with a default of 3 packets. Configures
the number of duplicate packets to transmit during a
low-speed T.38 fax call.
Hs Redundancy Range 0-3 packets, with a default of 0 packets (no redundancy). Configures the
number of duplicate packets to transmit during a high-speed T.38 fax call. Note:
Setting the HS Redundancy parameter greater than 0 will cause a significant
increase in the network bandwidth consumed by the fax call.
