GPON Card Provides GPON interfaces and one RST button to reset the

line card. This card is responsible for the TDM service flow. The ONT encapsulates the IP traffic to GEM frames. The GPON card receives these GEM frames and transports them to main control and switching card.

GPON line card has two modules: GPON MAC module

TM module

24

GPON MAC Module GPON MAC module is responsible to complete all PON levels and

supports the following functions: G-PON TC (GTC) framing and deframing. G-PON Encapsulation Mode (GEM) framing and deframing. Mapping and demapping between the service packets and GEM frames,

GEM-based assembling and disassembling. Achieving normal operating of OLT status mechanism including ONU

registration and ranging as specified by G.984.3 regulations. Realizing the uplink ONU bandwidth allocation mechanism. Realizing the downlink data encryption and the downlink FEC. Realizing the transparent transmission of OMCI passage. Achieving OLT side alarm test as specified by G.984.3 regulations. Obtaining the performance statistics and bit errors on GEM packet sending

and receiving.

25

TM Module GPON TM module provides the service level processing and

supports the following functions: Service forwarding with VLAN directly connecting and bridging.

VLAN processing.

Priority marking.

Flow classification and access listing.

Queue dispatching, uplink/downlink service and bandwidth management.

Multicast control with the SCB and ONU multicast modes.

Non-emulation TDM service processing.
