Channel bank gives live upgrade possibility. I could bring another one 
channel bank, do a ztcfg, do asterisk reload and having total downtime 
less than 1 minute, which is less then required level.

While TDM2460E stops at 4 (guessing) cards in one PC box. (and 5th card 
for Telco connection, a card with at less 24*4=96 public access channels).
So i think that TDM is not very good option. While SIP ATA gates give me 
   almost as low as 0 s down time, they require more work on asterisk 
Box (cpu, net).

maybe someone could say which channel bank to choose:

a) Zhone->cheepest
b) Adtran 750 discontinued
c) Rhino, good but expensive.

Anyone wiling to share his experience with above hardware?
