asterisk users - Apr 2005 - Channel bank of E1s? (one E1 input --> 2 x E1 output)

Hi,

Assume I have one E1 digium card to which I want to plug two distinct E1 PABXs ,
one with 15 channels and the other with 15 channels;

Is there a sort of E1 multiplexer devise that allows me to plug in one hand the
E1 port of the Digium card and on the other hand the two PABXs? In this same
devise, I should be able to say that 15 channels need to go to first Interface
and 15 other channels need to go to other interface.

Or is it necessary to acquire a another E1 card although I don't need to
process
more channels (30 channels are ok).

Any help is greatly appreciated.

Hi all 
 
I have installed version 0.9 against a supplier SIP and have put a AVM B1
like backup.  
 
The reception of calls works perfectly, but with himself not to make calls
to ISDN card.  
 
It is possible that this configuration works whith *@home ? or I am
mistaken. 
 
AVM card is CAPI and * @home can create ZAP channels. How I create a CAPI
channel? 
 
Excuse me for my very poor english :-( 
 
thanks in advance

yes, some multiplexer allows that, but they're quite expensive
compared to another E1 card for asterisk.
I think you'll need at least 1k $$$ for a such splitter.

Matteo.

Many channel banks have two T-1 connectors and support a feature called 
'drop and insert'.  This allows some of the DS0 channels to be cross 
connected from one T-1 connection to the other.  The first T-1 connection 
can go to the telco or an interface card in a computer, and the second T-1 
can go to another channel bank.  Some of the channels can be dropped off at 
the first channel bank while the rest can continue on to the second channel 
bank.  You are asking about E-1 and PBX instead of T-1 and channel bank, 
but if I understand the 'drop and insert' correctly, and if your
hardware
supports it, this may work for you.
