[Asterisk-Users] Channel bank of E1s? (one E1 input --> 2 x E1 output)

[Neal Walton]

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.
