[Asterisk-Users] Pros and Cons of T1/E1 cards

[David Waugh]

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

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.
