Description

0 - 1

-

Outgoing call priority set as follows:

• 0 - Incoming call priority on all circuits.
• 1 - Outgoing call priority on all circuits.
• 2 - Highest point code has priority on even cics.
• 3 - Highest point code has priority on odd cics

2

ISPGOP_ACM_CTRL

If set to 1, the ISUP module will run timer T7 whilst
awaiting ACM. If set to zero timer T7 will not be
used.

3

ISPGOP_ANM_CTRL

If set to 1, the ISUP module will run timer T9 whilst
awaiting ANM. If set to zero timer T9 will not be
used.

4

ISPGOP_SUS_CTRL

If set to 1, the ISUP module will run timer T2 or T6
whilst in the Suspended state. If set to zero timers
T2 and T6 will not be used.

5

ISPGOP_RST_REQD

If set to 1, the state of the circuit once configured is
'unknown' and must be reset before becoming
available for use by ISUP. If set to zero, the state
of the circuit once configured will be initialized to
'idle'.

6

ISPGOP_REQ_CLI

If set to 1, the calling line identity (CLI) will be
automatically requested during incoming call set-up
if not provided in the IAM.

7

ISPGOP_EN_ST

If set to 1, an ST (end of dialing) address signal will
be generated (i.e. a SAM containing only an ST
digit will be generated) and issued to the user
during incoming call set-up after a period of T10
after the last address signal has been received, if
no ST digit was included.

8

ISPGOP_USR_SVC1

If set to 1, the user application is able to process
user to user supplementary service 1. If set to
zero, incoming calls containing an essential user to
user service 1 request will be released by the ISUP
module with cause 69, ‘requested facility not
implemented’.

9

ISPGOP_USR_SVC2

If set to 1, the user application is able to process
user to user supplementary service 2. If set to
zero, incoming calls containing an essential user to
user service 2 request will be released by the ISUP
module with cause 69, ‘requested facility not
implemented’.

10

ISPGOP_USR_SVC3

If set to 1, the user application is able to process
user to user supplementary service 3. If set to
zero, incoming calls containing an essential user to
user service 3 request will be released by the ISUP
module with cause 69, ‘requested facility not
implemented’.
