Service access capabilities and method used to process client services in ODU1 convergence mode

TOA, THA, and TOM boards support ODU1 convergence mode. In this mode, each ODU1 signal is divided into 16 timeslots, each of which occupies 155 Mbit/s bandwidth. Client services are sliced into 155 Mbit/s fragments and mapped into ODU1 signals. In this way, multiple low-rate services are converged into one ODU1 signal, improving bandwidth usage. For example, GE services occupy 7 timeslots, STM-1 services occupy 1 timeslot, and FC100 services occupy 6 timeslots. All the preceding services can be transmitted together in one ODU1 signal.
