Re: [TIProtocol-askcisco] sprops parameter set for CTS 1000 version 1.7

[Aravind S. <ara...@te...>]

Hi nermeen and Steve,

I have done a packet capture of the actual media and have not been able 
to do a decode via videsnarf or other tools. This lets me think there 
may be missing in-band parameters. I could be wrong. Is this a valid 
assesment?

thanks
aravind
