Re: CEOP or STUN for Nortel 7400 replacment

Hi Shady,

Not sure what microwave radio u are using but check with radio vendor first
if they can replace your ATM unit (usually a box sitting inside below tower)
and make it ethernet output.

OR

Buy new GE ethernet backhaul radios (Ceregon or few others are microwave
good and stable).

Once youve decided above then you can put any cisco switch/router and carve
out your data and voice network.

For voice, CESoPSN (76xx series router) should work perfectlya s it has very
good clocking. If this doesn't work, your last solution would be looking at
TDMoIP products.

I'd stick with Cisco as they really works perfectly.
