and warm standby applications, and all connections must be re-established.

committed burst size (Bc)
The maximum amount of data (in bits) that a network agrees to transfer under
normal conditions over a measurement interval.
committed information rate (CIR)
The rate (in bit/s) at which the network agrees to transfer information over a
connection. It is related to committed burst size (Bc) and measurement
interval (T) as CIR = Bc/T.
common header
A small Nortel Multiservice Switch node-specific common frame header that
is appended to the front of frames and cells that are routed between Nortel
Multiservice Switch nodes.
common channel signaling (CCS)
A signaling system in which signaling control data for all channels on a facility
is carried on a single separate channel in the form of a data protocol. For
example, the control signals for 30 voice channels are carried on an ISDN
PBX trunk, and the data channel (D-channel) is carried in one of the remaining
channels.
