Application
Multiple Sync or Async DTE devices
time-division-multiplexed onto one or
two synchronous DCE communication
links and demultiplexed by an identical
unit at the far end.
Timing
System Timing: External via Composite
Port or Internal Timing for back-to-back
connections
Each sub-channel Port capable of
accepting external TXC to clock TXD for
DCE to DCE crossover
Port Capacity
Composite : One or Two Ports
Channels: Up to sixteen ports
Data Format
Data transparent at all data rates. Async
data converted to synchronous format
internally
