Abstract
One embodiment provides an optical line terminal (OLT) module in a network device. The OLT module includes an optical signal module, an OLT management module, a scheduler module, and a forwarding module. The optical signal module transmits optical signals to and receives optical signals from a number of optical network units (ONUs). During operation, the OLT management module identifies a remote OLT module operating at a lower upstream data rate than the OLT module. The scheduler module identifies a report message received from a first ONU operating at the lower upstream data rate and generates a grant corresponding to the report message. A grant specifies a time slot for an upstream data burst. The scheduler module includes the grant in a notification frame destined for the remote OLT module. The forwarding module forwards the notification frame to an internal switch of the network device.
