[VoiceOps] recommendations for PRI/POTS/DATA CPE device with fiber handoff

I was looking at a variation of your idea.


The MX408e.

8 DS1 circuit emulated T1 interfaces
4 10/100 ports
1 SFP port for uplink to us.

And can work in a p2p or point to multipoint configuration.
NEBS complaint for CO installation.

I have so many TA6xx boxes laying around it is pathetic so there
are my POTS.

It just seems QoS might be an issue as I would be relying on the
box to prioritize the emulated T1s and I am unclear how well it
does it. TA90Xe boxes I like and trust.

Plus it is a lot more complicated and expensive. I would have to
buy 3 to start. One for the CO, one for the customer, and a spare.
My PRI would still be TDM based, the POTS would be TDM based from
GR303, etc...

Your idea is nicer. Especially if I do not have to buy new cards
for a TA5000 or what not to get it working temp with a SFP like
