In order to can more pure and freshly understand following examples, first EPOC network system result and operation principle are simply introduced.

As shown in Figure 1, in EPOC network system, the transmission direction of OLT to CNU is down direction, adopt TDM (Time-DivisionMultiplexing, time division multiplexing) mode, namely downlink data sends is continuous print, and information broadcasting is issued each CNU by OLT continuous print, and each CNU selects one's own data receiver.

CNU to OLT is transmitted as up direction, adopts TDMA mode, and namely upstream data sends is burst, and different CNU takies different ascending time slots, and multiple CNU shares up link by time-multiplexed mode.The guard time interval avoided conflict is had between each ascending time slot.

In order to ensure that upstream data can not occur to send conflict, up transmission needs to adopt ranging technology, measure the descending loop time delay being sent to the data-signal of uplink receiving of OLT, and carry out delay compensation accordingly, ensure that upward signal at each CNU is after common optical fiber is converged, and inserts the time slot of specifying, neither collides to each other, also gap is too not large, even if the time that the signal that different CNU sends arrives OLT is different.

As shown in Figure 2, for the system configuration schematic diagram of EPOC, wherein, CMC is used for the form becoming to be adapted at by the format conversion of the data come from area of light transmission to transmit in coaxial territory, can also be used for the form becoming to be applicable to by the format conversion of the data come from the transmission of coaxial territory to transmit in the optical domain.

Before OLT and MC and CNU carries out transfer of data, first need to initiate registration to OLT, can comprise: area of light registration, coaxial territory registration etc.

In existing EPOC system, CNU to be registered adopts EPONMPCP register flow path completely, lacks coaxial physical layer to the training of channel, negotiations process; In addition, area of light is registered at same absolute time window with coaxial territory simultaneously, and the probability sending conflict is large, and then reduces the performance of system.

In order to solve the problem, the present embodiment provides a kind of method of the registration based on EPOC system, and the executive agent of the method is CMC, as shown in Figure 3, can comprise:
