other numbers.
Connect the CCI com1 connection to a ground connection.
Connect the CCI NC1 connection to the central office
demarcation.
Tips -
CCI signaling to report power loss or malfunction
of the DID Trunk Cartridge is not supported by all carriers.
For carriers or installations which do not use CCI signaling,
the CCI and ET connections are treated as not connected.
Wire each CCI independently to the central office. If the
connections are wired in parallel, any CCI trouble disables all
DID Trunk Cartridges. If the connections are wired in series,
all DID Trunk Cartridges must fail before the central office
recognizes the trouble condition.
