Hi!
I have some (short) question about the Eicon DIVA (V-)4BRI cards I want
to have (short) answered before buying the DIVA card. I know there are
several Eicon guys active on the list, thus I ask on the list instead of
directly to Eicon so that all other will benefit as well.
1. Do Eicon DIVA (V-)4BRI cards support TE and NT mode?
2. Can the clock (master/slave) be configured independent from the mode
(TE/NT)
3. Is the PIN layout for TE or NT mode?
4. When I change the mode (implies 'YES' for question 1), will this also
change the polarity on the connectors or do I have to use a
BRI-crossover cable?
5. If a call is bridged from BRI->BRI, is it done directly on the BRI
card or via Asterisk
6. Difference between V-4BRI and 4BRI: As far as I understand the 4BRI
is the better (more expensive) card which also offers FAX on/offramp.
Nevertheless I can use V-4BRI for faxing when using spandsp. Both cards
do support onboard echo cancellation. Are this assumptions correct?
Usage in Asterisk: please correct me if I'm wrong:
- Communication between the DIVA cards and Asterisk always happens via
the CAPI interfaces.
- For the Asterisk part I have the choice of chan_misdn or
chan_capi(-cm). After reading I come to the conclusion that
chan_capi(-cm) should work better.
- For the hardware part there are also 2 choices. Either use the Eicon
drivers included in 2.6 and divactrl or use the source packages from
eicon and the tools included. Here I'm not sure which method is better.
Further I do not know how this is related with isdn4linux or other linux
ISDN stuff. From: http://www.eicon.com/support/helpweb/slnxen/asterisk.asp
1. "Ensure that you do not have the ISDN4Linux driver or the HiSax
driver installed." What is the ISDN4Linux driver? Is is something
generic in Linux or do they talk about a certain ISDN4Linux driver for
Eicon cards?
2. " ...install the isdn4k-utils-devel package...". What is isdn4k ?
I'm a little bit confused about what I have to install.
Thanks for clarifications
regards
Klaus
