Page 90 - Part 2 Voice Over IP How Do I?
Step 1- INDeX environment
This step details the requirements for setting-up INDeX to INDeX telephony.
IPNC channel type
From INDeX software Level 10.0+ the IPNC channels can be optionally
configured as either Trunk (T type) or Subscriber (S type).
(T) Type
Operating as (T) type, IPNC offers full INDeX to INDeX feature transparencies.
This is achieved by tunnelling the User-to-User information within the layer 3 call
setup exchanges. For advanced INDeX Administrators the T type channel is the
same as that for a DPNSS trunk. Use T type channels when linking two INDeX
systems for VoIP.
Refer to the INDeX Programming Manual for details on programming Trunk
numbers, Sequential groups, etc.
Task
Description
Step 1
Ensure that INDeX has IPNC license (see
page 6).
This allows an IPNC (one license per IPNC) to have
32 channels on the INDeX backplane providing
2048K Bandwidth.
Step 2
From INDeX programming, ensure that the
next TRUNK number is correct.
This is to ensure that when the IPNC starts the trunk
field allocated to each channel (32 with license)
increments numerically. This ultimately makes
programming of the INDeX easier.
Step 3
Create a new group on the INDeX. Ensure that
this new group is a Trunk Sequential group.
Step 4
From INDeX programming, program the 32
IPNC trunks into the Trunk group created
above.
This group is used in the INDeX Network Routing
Tables when configuring the INDeX when setting up
the DPNSS activity.
Step 5
Program the INDeX Network Routing Tables to
have the remote INDeX node number and to
use the Trunk group created above. This Node
number should then use a VPN number. This
VPN is used by the IPNC to set up the VoIP
call.
When the extension number dialled across DPNSS
is called, the node number will prefix it automatically
by INDeX via programming. The VPN number is sent
to the IPNC cassette via the trunk group containing
the IPNC channels. The IPNC acts on the VPN
number matched in it's Shortcodes.
Step 6
Within INDeX programming, enter the remote
users numbers which will be on the INDeX
node number set up in the previous steps.
Dialled remote users need to be prefixed by the
node number. This programming step ensure that
this is done automatically.
Step 7
Repeat the process from steps 1-6 on the
remote INDeX but ensure the remote users
(step 6) are that of the original INDeX node.
This should now leave the two INDeX node network
at a point where the IPNC needs to be configured to
allow the call to proceed across the packet network.
