Composite Link

The composite link of the MultiMux is capable of synchronous,
asynchronous and digital communications. The MultiMux can be
connected to several different types of communications links through
various modems and DSUs connected internally and externally.
Internally the MultiMux can be configured with synchronous lease line
modem at a link speed up to 28.8K bps or a Data Service Unit (DSU) at
link speeds up to 56K bps. Externally the MultiMux can be configured
with either a synchronous or asynchronous composite link modem or a
DSU for digital communications. The external modems must have error
correction and should have data compression for increased thru put and
only hardware flow control.
