16.2.4 AIC-I Card
When provisioning the orderwire subnetwork, make sure that an orderwire loop does not exist. Loops
cause oscillation and an unusable orderwire channel.
Figure 16-4 shows the standard RJ-11 connectors used for orderwire ports.

16.2.4.4 Power Monitoring
The AIC-I card provides a power monitoring circuit that monitors the supply voltage of –48 VDC for
presence, undervoltage, and overvoltage.
16.2.4.5 User Data Channel
The user data channel (UDC) features a dedicated data channel of 64 kbps (F1 byte) between two nodes
in an ONS 15454 network. Each AIC-I card provides two user data channels, UDC-A and UDC-B,
through separate RJ-11 connectors on the front of the AIC-I card. Each UDC 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 UDC ports are standard RJ-11 receptacles. Table 16-13 lists the UDC pin assignments.
