Figure 1 shows the PM6341 E1XC used with the PM7345 Saturn User Network
Interface for PDH (S/UNI-PDH™) to implement an ATM wide area User Network
Interface (UNI) or Network Node Interface (NNI).
In this example, the E1 LIU and framing functions are provided by the PM6341
E1XC.The combination of the E1XC with the S/UNI-PDH allows both PLCP
formatted E1 signals and ITU-T G.804 compliant E1 signals to be processed.
The G.804 specification defines ATM cell mappings for a variety of transmission
formats, including the 2.048 Mbit/s E1 format.
