Configuration 3

Configuration 3 is two MultiMux MMH908Ca/56 eight channel
multiplexers connecting a minicomputer at the local site to eight remote
terminals over a digital composite link. The MMH908Ca/56s have
internal 56K bps Digital Service Units (DSUs) tieing the MultiMuxes to
the Digital Data Service (DDS) network provided by your teleco facility.
The DDS network is connected to the MMH908Ca/56s at the INTERNAL
COMPOSITE LINK DIGITAL DSU connector on the back panel of the
MultiMuxes. The composite link is set for DDS clocking.
The INTERNAL LINK DEVICE DSU LED in the middle of the front panel
of the MMH908Ca's is lit for this configuration. The channels are set up
with the same considerations as in Configuration 1. The List Composite
Link Configuration ($L) command is shown in the following example for
an internal DSU.
