This table specifies a list of CAS profiles. Each CAS profile
consists of the configurable CAS attributes related to:
. Line signal timers table, ccasIfExtLineSignalTimerTable.
. Register signals table, ccasIfExtRegisterSignalTable.
. Register signal timers table, ccasIfExtRegSignalTimerTable.
. General configurations table, ccasIfExtGeneralConfigTable.
A CAS profile can be applied to a DS0 group of the DS1 line
with CAS signaling. A DS1 line is configured for CAS signaling
when its dsx1SignalMode is set to 'robbedBit(2)' for T1 or
'bitOriented(3)' for E1.
