So this is a bad idea but it¡¯s my house, where bad ideas reign supreme
?
?
In the living room I have a Cisco VTC camera -> DM-TX-201-C ---(direct DM link)--> DM-RMC-100-C --> Cisco C-series CODEC (Video) and switch (LAN) in the garage data rack.
?
Using a mic that requires Phantom power and not having any unused copper pairs between the living room and the garage I¡¯m using a Biamp EXPI to phantom power the mic and turn it into Cobranet, then an EXPO in the garage to feed it into
the CODEC (there is no DSP, the EXPI generating unicast bundle 277, the Expo is receiving unicast bundle 277)
?
The garage end of the equation is fine ¨C plenty of switchports, EXPO is directly patched to the switch.
The living room end of the equation is strange ?-- if I plug the EXPO into the courtesy port on a Cisco phone all is happy, but if I try using the courtesy port on the DM-TX-201 no audio comes out the other end.
?
I know it¡¯s not the best (practices) idea but I can¡¯t think of a technical reason for it to work downstream of a Cisco phone but not to work on a DM-TX ¨C and I¡¯ve verified all of the ports are on the right VLAN ?¨C has anyone done this and
had it work?
