3.13.3 Connection
The HCS-4857 series congress unit is equipped with
two RJ45 sockets supports daisy chain connection via
cat5e cable. When connecting the CMU to the
contribution units, the CBL8P2RJ45
converter cable is needed to connect the first unit to the
socket of the CMU.

For a longer distance between the contribution unit and
the CMU/EMU, a Cat5e cable can be used. One end of
the Cat5e cable is connected to output of the main unit
via the CBL8P2RJ45S converter cable; the other end
of the Cat5e cable is connected to the contribution unit.

Neither the replacement of congress units nor cable
faults between congress units will affect the other units
if “Closed Loop - Daisy Chain” connection topology is
selected. “Closed Loop - Daisy Chain” connection,
achieved by closing the loop of the daisy-chained units,
increases system reliability. For “Closed Loop - Daisy
Chain” ring connection, HCS-8600MCLS Loop switcher
is needed. The "TO MU" port of HCS-8600MCLS is
connected to the output of the main unit via
CBL8P2RJ45 converter cable; the other port of
HCS-8600MCLS is connected to the contribution unit;
at last, connect the last contribution unit back to the
CMU via a CBL8P2RJ45S converter cable.

3.13.3.2 Connection between congress units
All congress units of HCS-4857 series congress units
system are daisy-chained easily and conveniently by
dedicated Cat5e cables. When connecting to another
congress unit, just connect the RJ45 socket by Cat5e
of a congress unit with another.
