For adding another E1 as more bearer channels, it's as simple as adding 
the additional channels in your linkset declaration.  So below your 
channels that you have already declared, append another "cicbeginswith" 
line with your starting CIC for the first channel of the additional E1, 
and then append your "channel" line with the additional channels.

One nice thing about libss7 is that it doesn't care about your span 
configuration below it.  It only cares that you tell it which Zap/ 
channels to use, and which CICs are mapped to the Zap channels and it's 
happy.
