In the following example, the MULTIPLEXER UNIT utilizes an optical fiber
connection between a pair of units to provide 4, 8, 12 or 16 channels of E1, T1, Datacom, or
1 to 4 channels of Ethernet Bridge between the units.
The timing scheme for the typical point-to-point application would set all connected
E1 or T1 equipment to recovery (receive timing from the MULTIPLEXER UNITs ).
