Bit Number Mnemonic Description
11 ISPGOP_COM If set to 1, the user application is permitted to send
a Call Offering Message (COM) to the network.
This option is intended for use only in the Italian
national network and should otherwise be set to
zero.
12 ISPGOP_T35 If set to 1, protocol timer T35 will be enabled. If set
to zero, timer T35 will be disabled. T35 is started
on receipt of an IAM from the network and restarted
on receipt of any SAM messages until an ST digit is
received. If the timer expires, the call is
automatically cleared.
13 Reserved Reserved for future use and must be set to zero.
14 ISPGOP_TCCR_CTRL If set to 1, the ISUP module will run T104 which is
used whilst awaiting the LPA message after having
sent CCR. On expiry, the circuit is reset. If set to
zero, T104 will not run and the LPA message will
not be handled.
15 Reserved Reserved for future use – set to zero.
ext_options
The extended options field allows various run-time options as shown in the
following table to be selected for the circuits in the circuit group.
Bit Number Mnemonic Description
0 ISPXGOP_BLK_767 This bit selects the abnormal circuit group
blocking procedures to be used and should be
set as follows:
• 0 - Q.764 (Blue Book) operation
• 1 - Q.767, Q.764 (03/93) and ANSI T1.113
operation
1 ISPXGOP_UBK_MH If set to 1, a received circuit group unblocking
message will remove both the remote
Maintenance and Hardware blocking conditions
regardless of the value of the received circuit
group supervision message type indicator.
Otherwise, the type of a received Unblocking
message must match that of the previously
received Blocking message to remove the
remote blocking condition.
2 ISPXGOP_RPT_CGSM If set to 1, the ISUP module will repeat CGB
messages for each circuit group blocking
operation and repeat GRS for each circuit group
reset operation. If set to zero, only one message
will be issued for each operation.
Note: this option should be set for ANSI based
operations.
3 ISPXGOP_UMSG_CFN If set to 1, when the module receives an
unrecognized protocol message it will issue a
‘Confusion’ (CFN) message and will recognize
receipt of a CFN message.
