Where can I find a good tutorial on how channel banks work? I need to get a 6 port (or so) channel bank for FXO. I need to find some information on which ones are supported well under Linux and with Asterisk, how to configure them, what specifically to look for in a channel bank, etc. I'm pretty new to all this, so I'm not familiar with a lot of the terms and such. Thanks! Steve

I'm looking to install a system with 80 FXS analog phones. At this time the only cost effective solution is using a 4 port T1 card and addit 600 channel bank. Has anyone tried this solution? any good documents beside http://www.voip-info.org/wiki/index.php?page=Asterisk+hardware+channel+bank+check as far as i know, addit 600 T1 interface is not PRI (please correct me if i'm wrong) its CAS

Hi all, I'm currently evaluating ideas for a phone system for our new office and I have a copy of Asterisk along with a couple of H.323 phones setup in the lab here. I'm very impressed - thanks for the great software! (I was especially impressed that the IAX connection to Digium worked out of the box like that - someone at Digium no doubt has a voicemail from me this morning!) ;-) What

hi, i have some newbie questions about channel banks. i have an adtran act-1241 sitting around. it accepts D4 modules, and it contains a number of e&m cards. first of all, how does this thing work? a t1 contains 24 channels, and i noticed that the channel bank has space for 24 cards. what do these cards do? what are their outputs? the ones that are in there have some outputs on the front

Hello, I've been planning to replace my aging CENTREX switch with a new PBX and am seriously considering Asterisk as my solution. I work at a college, and we currently support just under 300 regular analog lines to the offices and whatnot. I was wondering.. Is asterisk ready for such a job? Would I be making a mistake to deploy this across the campus at this time? It seems that

Jay, I have had a lot of trouble with the FXO ports on Adtran TA750. Unless the incoming POTS lines have a balance impedance, they will buzz very bad. Gregory P.

Hello, I am working for a charity in the UK and I am projecting a new phone system. We would like to connect our two-wire telephones (40 or so) to an ADIT 600 channel bank, and connect that into an Asterisk box via the CMG card or T1 card. I have been in talks with Carrier Access about the purchase of a new channel bank and we tried to get a minor version of it first for testing with the

Hi listers, I am looking for people who have used Power over Ethernet switches, primarily in conjunction with Polycom IP 501's. I've been looking at the Linksys SRW224P, since I've had good luck with the SRW224 in our office. However, Nortel, Cisco, Adtran, etc. all have an offering, all of which vary in price. I would appreciate any input people have to offer. Thanks, James

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

I'm starting to shop for my first channel bank and one of the features that eveyone seems to recommend is "far end disconnect supervision". What other terms do various manufactures use to describe this same feature ? Is "calling party disconnect" the same as "far end disconnect supervision" ? Thanks

Hi all, We are about to make our first channel bank install. This will be a one PRI outside connection and up to 70 extensions. As the schedule (and the budget) is pretty tight, I would like to learn a little bit more about general experiences with channel banks, like echo cancellation problems, Caller ID usage, etc. TIA, Paulohm

Hello, Did anybody successfully tried upgrade Adtran TSU 600 to firmware which is working properly with T100P and asterisk ? B.

Is there any advantage of getting a T1 card with a channel bank over 2-3 FXO cards ? Thanks. Dovid -------------- next part -------------- An HTML attachment was scrubbed... URL: http://lists.digium.com/pipermail/asterisk-users/attachments/20061031/0f74ec67/attachment.htm

Trying to find my feet here. If I wanted to connect Asterisk to a PRI and throw in a T1 Adtran channel bank into the mix for fax machines would the following work? Connect PRI line from telco to Port 1 on the Digium Wildcard TE205P. Connect Adtran TA-624-T1 to Post 2 on the Digium Wildcard TE205P also, would I need a crossover to the channelbank or is it a patch lead like the connection to the

I have two loop-start phone lines connected to an Adtran TA 750 channel bank. When a call comes into asterisk thru the first phone line and the call is redirect (in transit) back thru the second phone line, the channel bank will leave one or both lines opened (ie hangup with spawn a connection again). does any body have a suggestion: 1) I checked the cables into the channel bank from both phone

Hi, I have scanned through the archives of this list and found a number of question about hardware, but I just can not find the answer to my question. I am new to phone systems, I got "drafted" to come up with a new phone system for our company (I guess they figure since I know computers I know phone systems as well :O). We have 5 analog (I guess they are called PSTN lines) lines coming

I'm looking for some input from someone with real experience of telephony. I am having problems with the sound quality on our PSTN line calls. Our channel banks are Adtran 600 and 750 and I spent a lot of time on the phone with Adtran trying to work out the problem. We are getting hum and noise and very low volume on calls. I can increase the gain in zapata.conf but that increases the echo

I just picked up a couple CAC Access Bank 1s loaded with FXS that should be arriving shortly. Does anyone have one that they use with Asterisk? If so, would you be willing to shoot me a note with your current configs? I'm not very familiar with CAC/etc, and it would save me countless hours of muddling through .. :) Any others tips you can give me on these banks would be very
