Created by: Russ Noble on 28-03-2011 08:47:02 PM I'm looking for an alternate method of transversing data across networks during video conference sessions. We currently use a segment (VLAN) of the network to manage control system data for some specialized protocols we have developed. I'm wondering if using the sString or tString paths would allow me to transmit my data not only through point to point calls but also through multi-point and bridged calls.
My questions are these: 1. Does data sent into the sString or tString transverse the bridge to all connected enpoint, just the endpoints in the associated session, or no end points at all? 2.Does the bridge echo this data back to the transmitter? 3.What are the bandwidth restrictions on the data through this channel?
Any suggestions would be greatly appreciated

TString will work strictly point-to-point. SString is technically both point-to-point and broadcast, but in practice no one implements the broadcast functionality.
Thus, in practice, you'll unfortunately only be able to do this point-to-point.

The API says SString is being used for data the far end e.g for control systems, would this be all far ends in a bridge call? How would we implement this? I'd like to utilize the H.224 data channel for transmission of messages between control systems but I need to understand the endpoint implementation and the bridge handling of these messages. Also, what is the maximum message size accepted by TString and SString??
Thanks!

Subject: RE: TString & STring in-band data transmission Replied by: Russ Noble on 06-04-2011 05:25:48 PM I've done some testing with C60 codecs and a codian bridge. I've found that in point-to-point this works as you described but that when connected through the Codian that these messages are not transmitted.
Are there any plans to implement the broadcast or multicast from the bridge of the H.224 channel in future firmware updates?
