Chapter 16 Card Reference
16.3 Front Mount Electrical Connections
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 “DLP-G110 Create a User
Data Channel Circuit” task on page 7-20.
The DCC ports are standard RJ-45 receptacles. Table 16-14 lists the DCC pin assignments.
