Hi; We're looking to standardise on a single family of E1 PRI cards. I guess our options are : Digium / Zaptel / libpri Sangoma / Zaptel / Wanpipe AVM / CAPI eIcon / CAPI Junghanns / Bristuff Can anyone share any comparative experience of these, please ? Do they differ much in terms of interrupt requirement, CPU load &c ? Any info gratefully received. jd -- John Daragon john@argv.co.uk argv[0] limited Lambs Lawn Cottage, Staple Fitzpaine, Taunton, TA3 5SL, UK v +44 (0) 1460 234068 f +44 (0) 1460 234069 m +44 (0) 7836 576127
> AVM / CAPI > eIcon / CAPI > Junghanns / BristuffAs far as I'm aware, CAPI and Bristuff are BRI card so you can strike those off.
Hi John, I'm going to have to disagree with some previous posts. The Eicon Diva Server PRI/E1/T1 cards support an E1 interface and reduce the load of the call handling, echo cancellation etc as this is all processed on board on the card, and not on the central CPU of the computer. You can use the CAPI interface of the card combined with chan_capi_cm with the card. I have not found any problems when using different kernels or different versions of asterisk. I have one setup in our test lab here at Eicon with Asterisk so it does work! You can have up to 8 Diva Server cards in once machine - including a mixture of the analog and BRI cards. The Diva Server cards in two variants - the V-Series if you only want to use them with Voice based applications and the normal All-in-one cards if you want to do fax and RAS too. If you need any more information let me know, and I will assist further David -----Original Message----- From: asterisk-users-bounces@lists.digium.com [mailto:asterisk-users-bounces@lists.digium.com]On Behalf Of John Daragon Sent: 25 November 2005 00:46 To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: [Asterisk-Users] Pros and Cons of T1/E1 cards Hi; We're looking to standardise on a single family of E1 PRI cards.

Hi Steef, Do you want to send me an email to contact.centre@eicon.com and I can assist you further. It should work as far as I am aware.

I'm trying to get one to work but after fixing some some og the code they still do not work. When installing single CPU and 32 bit they work ok.

Hi Luke, It's important to compare apples and pears though. The card you mentioned has 24 on board Digital Signal Processors that enable it to do the following: * Tone Detection * Voice Activity Detection * Conferencing with automatic Gain Control and echo cancellation * Continuous full duplex audio support * Speech recognition support This means for example that the card could be used for a conferencing application with 24 users with echo cancellation/ gain control being handled by the card - and not having to be processed by the central CPU.
