SONET POINTER INTERPRETATION SYSTEM AND METHOD SONET POINTER INTERPRETATION SYSTEM AND METHOD |
摘要 |
PATENT 907-099 A SONET pointer interpretation in system which an Alarm Indication Signal (AIS) of a first type is interpreted as a subset of Loss of Pointer (LOP) of a first type. Specific events are defined for entering an AIS type 1 state and for exiting this state. Specific events are also defined for entering an LOP type 1 state and for exiting this state. Finally, a truth table is defined for mapping these states into a valid pointer (NORM) state, an AIS of a second type state and an LOP of a second type state.
