Ethernet Channel Bank

Hmm.

Caught my attention for more than 34 hours, you win.

I'm getting 24 port carrier access channel banks for $100, Digium 4 Port
Cards for about $800 (T400P) a card.. Meaning a blended cost of ~$12.50
per channel NRC. I can mux up 96 channels for a cost of $12.50 per channel
all day long. And easily sell it at $25 to cover the cost of the box per
port, T-1 channel per port, and channel bank per port non recurring costs.

Why am I looking at this post? Your cost is higher. Why would I bother? 
Give me influence.

Why would I think about buying a $400 2T portmaster for twice the price 
to achieve a lesser result as a 4 port and 4 T carrier access channel 
banks? 4 ports and 4 banks cost me about $1200, or about $12.50 NRC not 
including the associated hardware. Add on about 6 bucks a port. Even then, 
these costs still result in the same Hardware costs outside of the Channel 
Bank costs of a Portmaster. $400 is a rip for Channel Banks.

The CLECs are already hurting and need a quick solution, an 8 year return
plan isn't going to help anyone. Make it cheap and you'll win cash.

And have we discussed gr303 for oversubscription capabilities which * 
supports?

You need oversubscription capability, if you don't include this in your
design, you will fail. Period.

My two cents. 

I can have SS7 access pretty easily, can provide colo, and can provide a
machine, with capability for testing if desired. I think I also have
PM3s in inventory somewhere, email me. Lemme know. Dunno.

I'm also interested in the DSP's ability to provide codec trans and echo 
can. Actually, I'm really concerned with that as a primary, everything 
else is kinda noise to me ATM.

If you can get the original source for the comos you can probably get the 
layout of the cards, which means they can be reassembled for compactpci 
capability if that doesn't currently exist, which extends my interest. 

I am, however, interested in further comment on this thread, including 
PM3, Ethernet <-> DS0 bridging... continue discussion PLZ!!!!

cPCI is my current undying interest.

I have facilities if anyone wants to play.....

bkw input?

blah from 1am.

wherd.
