Bit Number Mnemonic Description
4 ISPX1GOP_T39 If set to 1, this will cause timer T39 (waiting for
IRS after sending IDR) to be initiated. If set to
zero, timer T39 will not be initiated after
sending the IDR message.
Typically, this option would be set for the
MCID supplementary service at a destination
exchange.
5 ISPX1GOP_T38 If set to 1, this will cause timer T38 (wait for
RES message) to be initiated. If set to zero,
timer T38 will be disabled.
6 ISPX1GOP_SEND_UPT If set to 1, this will enable the user part
unavailability procedure to be initiated by
causing a ‘user part test’ message to be sent to
the network when a MTP-STATUS message
indicating “user part unavailable – inaccessible
remote user” is received.
This option will dictate whether a ‘user part test’
message is sent on receipt of an MTP-STATUS
primitive and will not affect the sending of a
‘user part available’ message in response to
the ‘user part test’ message.
Note that all groups with the same DPC must
have the same setting of this option otherwise
configuration will fail.
For ITU-T operation, if this procedure is
initiated a UPT message will be sent to the
network and the ISUP module will wait for a
UPA message in response.
7 ISPX1GOP_TX_CRG The ISUP module supports a generic
mechanism for handling the Charge (CRG)
message providing that the variant used is
based upon ITU-T.
If set to 1, any Charge Request primitive
received by the ISUP module from the user
application will be passed in the transparent
format to the network and a CRG message
received from the network will be passed
transparently to the user as a Charge Indication
primitive.
Note: this option is applicable to ITU operation
only. If using Italian ISUP this option should
not be set since specific handling has been
implemented for this variant).
8 ISPX1GOP_CCL If set to 1, any Calling Party Clearing Indication
received will be passed transparently to the
user application.
If set to zero, when a Calling Party Clearing
Indication is received, this message will be
mapped to a Release Indication with a
proprietary cause value of 0x7c (to indicate that
a Calling Party Clearing Indication has been
received) and sent to the user application
instead.
9 ISPX1GOP_AUTO_BLK If set to 1, this will enable Circuit Group Auto
Blocking functionality. A Heartbeat message
will be sent by ISUP to the User Instance which
must be confirmed.
