WebGPON Downlink Frame Structure. Each GTC (GPON Transmission Convergence) frame consists of PCBd (Physical Control Block downstream) and payload. Downlink frame’s fixed 125us frequency is 8000Hz, and its’ size is 38,880 bytes, when speed rate reaching 2.488Gbps. GTC payload definitely is the “payload” of GEM Frame in downstream. WebA compatible frame structure between collocated networks with adjacent frequency assignments must be established. Carriers using TDD must have a guard period between uplink and downlink transmissions. DL signal can potentially leak into adjacent channels using TDD and FDD LTE guard banding is no longer in place to lessen the impact.
