Table 5-43: E1/T1/J1 Configuration Parameters
Defines CAS protocol for each trunk ID from a list of CAS protocols
defined by the parameter CASFileName_Y.
For example:
CASFileName_0 = 'E_M_WinkTable.dat'
CASFileName_1 = 'E_M_ImmediateTable.dat'
CASTableIndex_0 = 0
CASTableIndex_1 = 0
CASTableIndex_2 = 1
CASTableIndex_3 = 1
Trunks 0 and 1 use the E&M Winkstart CAS protocol, while trunks 2
and 3 use the E&M Immediate Start CAS protocol.
Note: For additional CAS table ini file parameters (CASFileName_0,
CASFileName_1, CASFileName_7, and CASTablesNum), refer to
'E1/T1 Configuration Parameters' on page 340.
The Dial Plan name that is used on a specific trunk.
The range is up to 11 character strings.
Alert Timeout (ISDN T301 timer) in seconds for outgoing calls to
PSTN. This timer is used between the time that SETUP is sent to the
Tel side (IP-to-Tel call establishment) and CONNECT is received. If
ALERT is received, the timer is restarted.
The ID is the trunk number (0 - 3).
The range is 1 to 600. The default is 180 seconds.
ID = Trunk number (0-73).
[0] Don't Play = The ISDN / CAS gateway doesn't play a Ringback
Tone (RBT). No PI is sent to the ISDN, unless the parameter
'Progress Indicator to ISDN' is configured differently.
[1] Play on Local = The CAS gateway plays a local RBT to PSTN
after receipt of a 180 ringing response (with or without SDP).
Note: Reception of a 183 response doesn't cause the CAS
gateway to play an RBT (unless SIP183Behavior = 1).
The ISDN gateway functions according to the parameter
LocalISDNRBSource:
1) If the ISDN gateway receives a 180 ringing response (with or
without SDP) and LocalISDNRBSource = 1, it plays a RBT and
sends an Alert with PI = 8 (unless the parameter 'Progress
Indicator to ISDN' is configured differently).
2) If LocalISDNRBSource = 0, the ISDN gateway doesn't play an
RBT and an Alert message (without PI) is sent to the ISDN. In this
case, the PBX / PSTN should play the RBT to the originating
terminal by itself.
Note: Reception of a 183 response doesn't cause the ISDN
gateway to play an RBT; the gateway issues a Progress message
(unless SIP183Behavior = 1).
If SIP183Behavior = 1, the 183 response is treated the same way
as a 180 ringing response.
