I have a 3600 and a 3810 both with E1 voice module

On the routers is the bit patterning

i.e. define bits) locally significant or must it match end to end in this case

[s.jankowski]

Are you talking about signaling bits? Signaling bits must be received by the destination PBX.

The PBX connected to the 3810 is using custom bit patterns hence not using the cisco defaults for idle 1101 & seize 0101.
