2.7.6 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 DCCs, DCC-A and DCC-B, through separate RJ-45
connectors on the front of the AIC-I card. Use a shielded RJ-45 cable. Each DCC can be routed to an
individual optical interface in the ONS 15454.
The DCC ports are standard RJ-45 receptacles.
