I need a good reliable source for channel banks. Ebay is nice but too many variations of quality. I need one that can do 8 FXO and 16 FxS does anyone have a particular model, other than adtran that they can recommend??? And if possible include a source to buy from... Thanks in advance, Alex -------------- next part -------------- An HTML attachment was scrubbed... URL: http://lists.digium.com/pipermail/asterisk-users/attachments/20030514/af1966a9/attachment.htm
What channel banks are best supported by asterisk, and available new at preferably decent prices?? It would seem that for small offices with less than 15 users, a single port T1 card with a channel bank, with say 15 FXS and 9 FXO (or similar config) would be ideal. So I would like to find channel banks that suit that sort of environment.... Also, I suppose you would also want channel banks for larger offices, generally as 100% FXS ports and using digital trunks for FXO (ie, pri). Regards, Adam

Well I disagree, there are numerous companies providing E1 channel banks, my personal favourite is J-tech of which I can find the damn link to their page for now ... Digging ...

Hi, Recently we started experiencing problems with our zhone z-plex 10-24S channel bank. Currently we are looking to get a replacement. Just wondering if anyone can comment on their personal experience or maybe give some pointers. We are looking for a reliable product to support a call center and live operators. Cheers.
We have 8 z-plex and they are fairly new! We replaced them with what is the best so far. adtran 750. We got them on ebay for around $ 500.00 new! With all the 24 fxs ports! ----- Original Message ----- From: "Alex Pavlovic" <alex@calltrex.com> To: <asterisk-users@lists.digium.com> Sent: Thursday, November 20, 2003 7:15 PM Subject: [Asterisk-Users] channel banks> Hi, > > Recently we started experiencing problems with our zhone > z-plex 10-24S channel bank.

OK, I'm having some trouble finding which equipment I need.... What I'd like to do is take about a dozen incoming analog lines and bring them into an * server. Of course one is going to have a hard time fitting a dozen X100P cards in a case, so an alternative would be a channel bank and a T100P in the * server. Now here's where my confusion comes in. I _think_ I need a channel bank that has a T1 interface on one side (to go to the * server), and FXO interfaces on the other (to accept the incoming analog lines from the telco)? And are there suggestions out there as to which channel banks one should select for this sort of deployment? -------------- next part -------------- An HTML attachment was scrubbed...

We use an Adtran Atlas 500 for this job (not for * but for our Mitel ICP 3300) you can aggregate FXO to T1 / PRI or any which way you want. It's a killer box and very easy to work with. Adtran support is, in a word, phenomenal. Very pricey, but ebay has some 800 models: http://search.ebay.com/search/search.dll?query=adtran+atlas <http://search.ebay.com/search/search.dll?query=adtran+atlas&ht=1&sosortprop erty=1&from=R10&BasicSearch> &ht=1&sosortproperty=1&from=R10&BasicSearch -----Original Message----- From: Kostur, Andre [mailto:Andre@incognito.com] Sent: Monday, January 19, 2004 9:30 AM To: 'asterisk-users@lists.digium.com' Subject: [Asterisk-Users] Channel Banks OK, I'm having some trouble finding which equipment I need....

Hello all; My buddy and I have been working on this asterisk server for a little while now and we both have one running at our houses. We are looking into ways to expand out to bigger servers and have hit a point of contention between us. We are looking for a way to put 12 FXO and 24 FXS onto an asterisk server. I feel we need to use PCI cards in the box and my friend says a channel bank will do the trick. I see how the pci cards talk to asterisk obviously but how does the signaling work on a channel bank is it Ethernet or do you still bring it into an fxo or T1 card on the server? Feel free to laugh but I can not get my head around how the channel bank works in this picture. Keith -------------- next part -------------- An HTML attachment was scrubbed...

Typical DS1 to DS0 channel banks like the Carrier Access (CAC) Access Bank have a T1 interface and then an Amphenol/RJ21 25 pair connector to connect to your POTS side.

Can anyone recommend a channel bank that works well with asterisk? I'm looking for two types: 1. 6-8 fxs/fxo 2.

Do not buy an adtran - no auto impedance match on FXO ports (echo, echo, echo) and no call disconnect supervision on FXO ports. Get the ADIT 600 (CAC) (also called a Cactus Lite), they have all those features and have a 48 port capability, plus callerid works wonderful. If you still want an adtran, I have 3 I can sell you for cheap :) Greg Gregory P.

My only complaint is echo. Some lines sound good, others echo all the time, some echo intermittantly or only when conferencing. I have tweeked the tx/rx gains and played with echo timing as much as possible. It is time to go to a channel bank (a PRI is still about $200/month more than POT's lines) . It appears the favorite channel banks are CAC and adtran. Am I missing anyone? Does one make or model perform better echo cancallation then the others? Are some channel banks still having problems with caller-id?

Has anyone used the ZPHONE Hi-Z channel bank w/ Asterisk? Any comments? I am looking for a unit that does a great job in adjusting to changing line impedances to limit echo.
we are about to deploy an asterisk server. on the external side we will have an ISDN30e plugged in to a E100P card. On the internal side i wish to use a channel bank. Which products work best for this solution? Can another E100P be used? and if so... what channel banks are compatible? where can they be purchased? and whats the approximate cost? please note we are in the UK Cheers -- Dan Goscomb <dang@cashcade.co.uk>
I have many old channel banks around that I would like to use to generate analog extensions. Will most channel banks work with Asterisk?
