[Asterisk-Users] BRI Newbie - What Hardware, PCI, in the US?
We are looking to lose the TDM400P in favor of an ISDN-BRI solution. This should get rid of static on the line (at least any static generated by our half of the circuit), right? I am a total virgin to ISDN. I understand that we need two BRI circuits to provide four voice channels, and that the hardware to speak to the BRI circuits can be passive or active, with the active type being much more preferred due to it's echo cancellation abilities. I do not even know which brands/models to consider that are out there. Given that we are in the US, and want to use BRI to improve sound quality (no echo, no static), what would be some good cards to look at? I hear a lot about BRIStuff, which I think is used on the Junghanns cards (like the quadBRI PCI ISDN), using the CAPI channel. Are those the Cadillac of ISDN cards? Sincerely, Brent A.

If you only need to service 2 BRIs, you might want to look at some of the passive options. We have a number of sites here in the UK running 2 HFC-S based cards in a box, all of which seem quite satisfactory (no echo, etc.). Over here you can pick up HFC-S based cards (the ones we use are these: http://www.solwise.co.uk/isdn.htm) for under ?20, so they're probably even cheaper on your side of the pond.

IMHO, the Diva Server BRI range of cards are worth considering. The Diva Server 4BRI card is an active card that can do echo cancellation, automatic gain control etc. The 4 port card costs similar to 2 single port cards so there will also be room to expand if you need it. More information can be found here: http://www.eicon.com/worldwide/products/MediaGateways/disv4bri.htm It is well supported by using the Eicon Diva CAPI Driver and the Chan-capi-CM driver from Melware. Not the cheapest but you will get good quality results. I have one running here. -----Original Message----- From: asterisk-users-bounces@lists.digium.com [mailto:asterisk-users-bounces@lists.digium.com]On Behalf Of Brent Torrenga Sent: 14 February 2006 18:57 To: asterisk-users@lists.digium.com Subject: [Asterisk-Users] BRI Newbie - What Hardware, PCI, in the US?

Hi Mr Gee I am using the Duxbury HFC PCI Bri card and found it to be very stable running asterisk-1.2.4 with Zaptel-1.2.3 with bristuff-0.3.0-PRE-1 on FedCore 4 Only problem is that you can only have FXO OR FXS on a card and not both on the same 1 port BRI card Regards Tertius Smit -----Original Message----- From: asterisk-users-bounces@lists.digium.com [mailto:asterisk-users-bounces@lists.digium.com] On Behalf Of Allan Gee Sent: 15 February 2006 13:01 To: 'Asterisk Users Mailing List - Non-Commercial Discussion' Subject: RE: [Asterisk-Users] BRI Newbie - What Hardware, PCI, in the US? My 5 cents worth is if you use Bristuff stable you must use Asterisk-1.0.10 ( Old version ) If you use Bristuff 3PRE1l you will have problems with FXO cards as I did. Bristuff3PRE1l is not Stable use at own risk!!!

You got a number of answers, but it wasn't clear to me which of them were actually in the US. My vague recollection was that the Junghanns cards weren't supported in the US. Anyone know if this is still the case? Doug -- Doug Meredith (doug.meredith@systemguard.com) SystemGuard - Oracle remote support 877-974-8273 (87-SYSGUARD) 506-854-7997 www.systemguard.com
