asterisk users - Feb 2005 - ISDN Phones With Asterisk

Hi,

I have an Asterisk Server with 4 T1. I want to plug my old ISDN phones 
in my Asterisk Server.

I have 128 ISDN phones to plug in my asterisk server.

This thing is possible? How can I do this? Wth a Channel Bank? With any 
other equipment?

Thanks,
Jeremy
