14.2.3 AIC-I Card
The AIC-I supports selective dual tone multifrequency (DTMF) dialing for telephony connectivity,
which causes one AIC-I card or all ONS 15454 AIC-I cards on the orderwire subnetwork to "ring." The
ringer/buzzer resides on the AIC-I. There is also a "ring" LED that mimics the AIC-I ringer. It flashes
when a call is received on the orderwire subnetwork. A party line call is initiated by pressing *0000 on
the DTMF pad. Individual dialing is initiated by pressing * and the individual four-digit number on the
DTMF pad.

When provisioning the orderwire subnetwork, make sure that an orderwire loop does not exist. Loops
cause oscillation and an unusable orderwire channel.

14.2.3.4 Power Monitoring

The AIC-I card provides a power monitoring circuit that monitors the supply voltage of –48 VDC for
presence, undervoltage, or overvoltage.

14.2.3.5 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, refer to the Cisco ONS 15454 Procedure
Guide.
The UDC ports are standard RJ-11 receptacles.
