Chapter 2 Common Control Cards
2.7.4 Power Monitoring
Table 2-15 describes the orderwire pin assignments.
When provisioning the orderwire subnetwork, make sure that an orderwire loop does not exist. Loops
cause oscillation and an unusable orderwire channel.
Figure 2-10 shows the standard RJ-11 connectors used for orderwire ports. Use a shielded RJ-11 cable.
Figure 2-10 RJ-11 Cable Connector
2.7.4 Power Monitoring
The AIC-I card provides a power monitoring circuit that monitors the supply voltage of –48 VDC for
presence, undervoltage, or overvoltage.
2.7.5 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 SDH network. Each AIC-I card provides two UDCs, UDC-A and UDC-B, through
separate RJ-11 connectors on the front of the AIC-I. Each UDC can be routed to an individual optical
interface in the ONS 15454 SDH system. For instructions, refer to th “Create Circuits and Low-Order
Tunnels” chapter in the Cisco ONS 15454 SDH Procedure Guide.
The UDC ports are standard RJ-11 receptacles. Table 2-16 lists the UDC pin assignments.
