[cisco-voip] 2951 with 64 FXS ports

Wed Apr 14 20:39:45 EDT 2010

I don't see the VG224s being discontinued anytime soon.  They are
comparatively new and fully supported (runs the same code including IOS
15 and commands as a router, does SCCP, MGCP, H.323, etc.).  They are
basically Cisco routers specialized for analog voice usage.  Since they
aren't modular they are cheaper to build and support.

They also come with RJ-21 connectors.  Are ports in use distributed (ie
RJ-11 jacks in offices) or all connected in a single location?  If
distributed, you can also just get a pre-wired 66 block with an RJ-21
connector, and then patch the wires in appropriately.  That's what I do
off of our VG224.

Thanks Lelio... I saw the 4 pack VG224, and my god is cheap !!! I don't
know for how long this model will be on the market (warranty and
support), but, I'll sure take a look at...

If you take a look at the data sheet, it explains that the module has an
RJ21 connector. You can break this out with a pre-made panel from
blackbox or do your own. With all FXS ports, it should be pretty easy.

I'm not really familiar with EVM-HD-8FXS/DID, can you please tell me
how can I use this to connect RJ-11 cable in? Some customer requires
VG with 48 FXS ports with RJ-11 interface for analog phones, but I
can't understand how this EVM-HD-8FXS/DID works.

Thanks
