Summary:                    [patch] Support for generic HFC-4S cards
Description: 
A patch to add some basic support of other HFC-4S -based PCI cards (such as
the ones made by Junghanns). 

Status: gets rid of the echo canceller messages when not needed, but still
needs work.

Specifically:
* It adds too broad a range of cards (which also include bero.net cards) 
* The range may include some 2-ports cards, which will probably not work.

Not yet tested to work, though it it is at least configured.

The clock on Junghanns cards seem to be different from B410P. By changing
the value of BRG_PCM_CFG, I get normal timing.

[jdg at tiare dahdi-linux]$ sudo dahdi_test

Then, Asterisk starts but shows notice messages 5-6 times per second:
chan_dahdi.c:10395 pri_dchannel: PRI got event: HDLC Abort (6) on Primary
D-channel of span 1

Anyway sometimes calls go through, in both direction.

Attaching my version of the patch.
