[Asterisk-Users] T1 echo canceller

[Michael Araba]

Thanks for the corrections. What would I call a unit that accepts a PRI
connection with a 10-channel PRI and an Ethernet output? 

 

I am looking into the Tellabs echo canceller now. Digium's echo
canceller offering is not suitable for my 1 PRI project because it is
probative cost wise.

Sorry to nitpick but a PRI is NOT a data/voice integrated T1.  A PRI is
a T1 with one channel (normally the last) used for call signalling.

If the T1 from the carrier is split into two pieces (data & voice) at
your office and the hand off to Asterisk is a T1 then it is not a
channel bank.  A channel bank splits a T1 into 1-24 DS0 voice channels.
If your interface with Asterisk is a T1 you should probably look at
getting one of the newer Digium cards with the add- on hardware echo
canceller.
