[Asterisk-Users] Port density: DS3 cards?

[Asterisk online forums]

Lucent TNT box price is attractive, but based on real experience it is
not very VOIP friendly. You have to consider it. It is hard to
interconnect with Cisco for example. I have no idea about Max
TNT-Asterisk interconnection.
We are using Nextone softswitch  and able to serve clients  and
interconnect via Cisco's to Max TNT only via NExtone, but direct
interconnect Cisco-MaxTNT almost impossible. However, if you are using
TNT's on both terminating/originating ends, then it is extremely great
solution.

Regards,
Alexander

Eight quad-span T-1 cards from Digium: $8,970
Three reasonable-quality asterisk servers: $1,000
One T-1/DS-3 MUX: $5000

Total system cost: $14,970

That actually sounds quite reasonable to me. However, if I were doing
this 
myself I would look hard at getting a MAX TNT with VoIP capability off 
eBay. The price would be equivalent or less, the interface would be more

complicated, but all the DSP would be done by the MAX.
