Hi, does anybody how we can test T-CCS(transparent CCS) on Cisco routers without PBX? Thanks

With one or two cisco routers perhaps.
What is the proprietary protocol that makes you think you need T-CCS in this case ?

Hi
Here is the scenario:
Customer's call center contains Genesys T-Server as CTI server which has PRI connects to AVaya PBX. T-server has to send NetworkCallID to PBX via the D channel and then PBX will send it to remote Avaya PBX over the Cisco router over H323. the router has PRI to PBX too. Apparently this NetworkcallID is propriertary and will disapear when reach the router unless we use T-ccs. Thanks
I can have two routers with T1 no problem. even more routers, as long as
1st step, make the trunk ready and verify with the show command
2. make calls from maybe Fxs port analog phone. etc

I would be curious to see this 'proprietary IE' becuase ASAIK the router will transport all what is know and more, see for example the GTD feature for ISDN:
However this said the T-CCS will transport the D-channel verbatim from one side to the other. when I was at cisco I've extensively tested it for tens of PRI and it works very well.
A test setup is not complicated. Two router in the middle are the T-CCS transport. Two more routers at the sides simulates the PBX. And you can place and receive as many calls you want.

In this link section how to test T-CCS without PBX, it seems requiring PPP in the wan. Why we need that/
2. Also how do we configure the signaling channel? Is it same as configure B-channel?

You don't need PPP or anything specific. This is VoIP and it works over any media.
Only the signaling channel is configured with "codec clear-channel". The others are configured with a codec of your choice, likely g.729 with vad. Then, all the channels are configured with connection trunk.

Cool.

If you have access to an standard ISDN PRI service, plug it into one side of the TCCS connection and plug the terminating device on the other side of the TCCS link. If it is working, the ISDN D channel should be up and you can make speech calls.
You don't need to run proprietary protocols over TCCS, you can use it to extend ISDN voice services over an IP cloud, we have done it in the lab many times.
Another option is to used a channelised interface on another router and use the TCCS to pass the data on the particular channel -
router1-----TCCS router--IP----TCCS router---router2
router1 -
controller e1 1/0
channel-group 0 timeslots 15 speed 64
...
interface serial 1/0:0
ip address 10.1.1.1 255.255.255.0
router 2
controller e1 2/0
channel-group 0 timeslots 15 speed 64
...
interface serial 2/0:0
ip address 10.1.1.2 255.255.255.0
if the TCCS link is up and timeslot 15 is using the clear channel codec, data should pass between router1 and router2.
