Abstract
A method is disclosed for replacing legacy interfaces of add drop ring optical networks using STS-3 granularity with an optical hub using STS-1 granularity. In order to avoid locking up ports on the optical hub with dedicated STS-3 packages, a signal broadcast feature of the optical hub, originally provided for remote provisioning, may be adapted to allow a single port to broadcast a signal on multiple and contiguous timeslots to the legacy networks expecting STS-3 granularity.
