CS1K H323 IP Trunks

See update: CS1K SIP/H323 Trunks

Release 4.5/5.5. CS1000 H323 IP Trunks are built on a virtual loop, and require a virtual D channel. Therefore, the customer must also support ISDN (eg: Integrated Services Digital Network Package 145, enabled.).

The procedure for building IP trunks is as follows:

LD 17: Create a virtual D channel
LD 97: Create a virtual superloop
LD 117: Configure a zone for IP trunks
LD 16: Build a route for the IP trunks
LD 14: Build the IP trunks on the virtual superloop
LD 32: Diagnostics (status)

The following bullet points are the key things to watch for and configure in Element Manager, although everything can also be programmed directly from the TTY using the prinouts below.

1. Create a virtual D channel

For the D channel card type (CTYP), enter D-Channel is over IP (DCIP)
For user (USR) select Integrated Services Signaling Link (ISLD)
For Interface type for D-channel (IFC) select Meridian Meridian 1 (SL1)
All other parameters are default.

2. Create a virtual superloop.

TYPE supl                
SUPL v96

Note:

Phantom superloops are for 500 type phones.
Virtual superloops are for IP phones and trunks.

A superloop cannot have both phantom and virtual sets on it and therefore must be configured as either phantom or virtual. Precede with "N" to designate phantom, "V" to designate virtual, or "X" to remove.

3. Configure a zone for IP trunks.

Configure a zone for IP phones, and another for IP trunks.

For example:

Zone 1 - IP phone zone (ZBRN MO)
Zone 2 - IP trunk zone (ZBRN VTRK)

LD 117

=> new zone

4. Build a route for the IP trunks.

Create separate routes for SIP and H.323 in LD 16.

For Trunk Type (TKTP), select TIE trunk data block (TIE)
For Incoming and Outgoing trunk (ICOG), select Incoming and Outgoing (IAO)
The route is for a virtual trunk route (VTRK).
Enter the zone number assigned to IP trunks.
Enter the Node ID, this must match the value configured in the Signaling Server.
For Protocol ID (PCID) enter H323 (or SIP)
For Mode of Operation (MODE), enter Route uses ISDN Signaling Link (ISLD)
For Interface type (IFC) select Meridian 1 (SL1)
Set an Access code for the trunk route (ACOD).

5. Build the IP trunks on the virtual superloop

Build all 32 at once: LD 14, NEW 32.

For TYPE select IP Trunk (IPTI)
Build your trunks on the virtual loop.
For Start in/out arrangement (STRI)/(STRO), use Immediate IMM for both.
There is no need to modify the default CLS options.

6. Diagnostics

IP trunks should establish, and be active.
If the DCH is 'stuck', try RST DCH XX in LD 96 to reset it.
