CR
Critical (alarm status)
Craft Interface Terminal (CIT)
The user interface terminal used by craft personnel to communicate with a network element.
Critical (CR)
Alarm that indicates a severe, service-affecting condition.
Cross-Connect Capacity
The total bandwidth of cross-connections as measured by the bandwidth of input and output
tributaries. A system with N STS-1 equivalent input tributaries and N STS-1 equivalent output
tributaries (referred to as
″
NxN
″
) provides a cross-connection capacity of N STS-1 equivalents.
This system could provide N one-way point-to-point cross-connections or N
2
two-way
point-to-point cross-connections at the equivalent rate of STS-1.
Cross-Connection Rate
The attribute of a cross-connection that defines the constituent signal rate it can carry.

D
Data Communications Channel (DCC)
The embedded overhead communications channel in the synchronous line, used for end-to-end
communications and maintenance. The DCC carries alarm, control, and status information
between network elements in a synchronous network.
Data Communications Equipment (DCE)
The equipment that provides signal conversion and coding between the data terminating
equipment (DTE) and the line. The DCE may be separate equipment or an integral part of the
DTE or of intermediate equipment. A DCE may perform other functions usually performed at
