I am confused about how CE1 ( Channelized E1 ) link is terminated at customer end (Hub end).
As per my knowledge there is one connection between E1 modem and E1 port on the router. But i want to know how the serial interface is connected. For ex: There is CE1 connectivity goes from one HUB location to "N" number of branches (one 64 Kbps per branch). So my doubt is whether there are "N" no of serial link termination in HUB end or only one serial connectivity the corresponds to D channel.
