16.2.4.6 Data Communications Channel

The DCC features a dedicated data channel of 576 kbps (D4 to D12 bytes) between two nodes in an
ONS 15454 network. Each AIC-I card provides two data communications channels, DCC-A and
DCC-B, through separate RJ-45 connectors on the front of the AIC-I card. Each DCC can be routed to
an individual optical interface in the ONS 15454. For instructions, see the
Data Channel Circuit" task on page
The DCC ports are standard RJ-45 receptacles.
