INDeX Environment (S) Type – Data Call
The following procedure should be used for the IPNC data call set up across
DPNSS or Qsig link when using the IPNC S type interface.
Because of this the configuration of the S type interface is more straightforward
than that of T type interface.
S type configuration requires the IPNC channels be placed in a group. The
remote INDEX is then configured to call this group over DPNSS.
For details on configuring the INDeX for S type signalling over DPNSS, etc.,
refer to the INDeX Programming Manual.
Task
Description
Step 1
Configure INDEX environment for DPNSS
signalling over an S type interface.
Use the S type for simplicity if inter-site VoIP is not
required
Step 2
Configure an IPNC subscriber group with
the IPNC channels on both INDeX systems.
Then use the normal DPNSS configuration
to route calls between these configured
groups over DPNSS.
When the IPNC2 channel group is called from IPNC1
the called number (i.e. the IPNC2 channel group) is
forwarded to IPNC2.
The called number must be configured on the RAS
extension of IPNC2.
The called number must also be configured on the
Calling IPNC1. This is set in the Number field of the
Configured Service
Step 3
Test Configuration
If the INDeX environment is configured correctly then
when the IPNC channel group is dialled the call should
be routed to the IPNC.
Use the IPNC Monitor application, select Call and
enable Call events. Point the Monitor application to the
local IPNC and dial the Group number configured
above. Use an on-switch extension to call both a local
and remote INDEX. You should see the number dialled
in the called field of the ISDN Layer 3 message.
The resultant tone returned by the on-switch extension
(i.e. engaged or busy) is NOT significant at this point. It
is only important that the call is presented to the IPNC.
