Ok, the Zhone sucks and the Adtran 750/850 seems to be a little too expensive. Can anyone recommend a decent channelbank that won't break the bank? TIA, -- Troy Settle Pulaski Networks http://www.psknet.com 540.994.4254 ~ 866.477.5638 Pulaski Chamber 2002 Small Business Of The Year

Zhones are a pain to configure and the FXO ports lack some features. Adtran may be expensive, but they are good. CAC products are also good but expensive. -- Steven Critchfield <critch@basesys.com>

They work fine with my T100p's. This is not strictly a commercial environment. I'm using them to interconnect the phones between my Seattle and Florida homes. The FXS interfaces are plentiful, pass caller id and seem to do what they are supposed to do. The FXO interfaces are really scarce. They also don't do callerid without a recent cpu card, per the Zhone site. And, I haven't found one yet. They are easy to configure. Google found several pdf manuals. They seem randomly listed as Premisys IMACS/600 or 800, AT&T Paradyne Acculink Access Controller, ADC ICX and others. FWIW, I also bought a rack of Tellabs echo cancellers for $50 and have one between the cb and the T100p. A little overkill, but very effective. Steve
This one seems less expensive. Does anyone have any experience with Rhino? http://www.channelbanks.com/ We don't have one yet, but probably will soon.

What are the model number of these Tellabls echo Cancellers do you then turn off all asterisk echo Cancellation in zapata Do you tuly have 0 echo now ???

Sure did.and does the canceller run all fxs & fxo channels or both ???
For FXS only, I like the CAC Access Bank 1s just because of the price. You can get 24 FXS ports for around $200 from ebay or resellers. For FXO or FXS/FXO, I like the CAC Adit 600s. They support FXO callerID (which the AB1s don't), have much better disconnect supervision than the AB1s, and they have 3 8-port cards instead of 2 12-port cards. That way you can do 8 FXO + 16 FXS or many other combinations. You can get 24 FXS ports for $500 - $600 and then buy additional FXO cards for $200 each or FXS cards for $75 each. One chassis actually supports 6 8-port cards with 2 T1s (48 channels). It also allows you to break out one T1 into some voice channels and some data channels which is nice for smaller offices. It also is configurable via telnet (ethernet) which I never cared about until I had it and now I wouldn't go back.> -----Original Message----- > From: asterisk-users-admin@lists.digium.com > [mailto:asterisk-users-admin@lists.digium.com]On Behalf Of Troy Settle > Sent: Monday, September 08, 2003 11:34 PM > To: asterisk-users@lists.digium.com > Subject: [Asterisk-Users] Channelbanks > > > > Ok, the Zhone sucks and the Adtran 750/850 seems to be a little too > expensive. > > Can anyone recommend a decent channelbank that won't break the bank? > > TIA, > > -- > Troy Settle > Pulaski Networks > http://www.psknet.com > 540.994.4254 ~ 866.477.5638 > Pulaski Chamber 2002 Small Business Of The Year > > > _______________________________________________ > Asterisk-Users mailing list > Asterisk-Users@lists.digium.com > http://lists.digium.com/mailman/listinfo/asterisk-users >
