Problems solved by technology

[0010] Along with the increasingly mature of VOIP technology, NGN will certainly replace existing PSTN user gradually, but how to realize the smooth switching of these two types of business, does not cause the loss of operator, also is the problem that the present invention will solve

Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings.

[0030] like image 3 It represents the implementation of V5 that realizes the narrowband uplink of the voice of broadband users. In order to realize the narrowband uplink of traditional PSTN users, a protocol processing function module is added to the EPON equipment. This function module controls the conversion of IAD from voice IP signal to TDM signal, and realizes the voice narrowband uplink of broadband users.

[0031] Figure 4 It is a flow chart representing the protocol processing module. In order to support voice streams of multiple protocol types at the same time, the protocol processing function module not only supports narrowband uplink of voice users but also supports intra-PON intercommunication of VoIP users. A registration address table is maintained in the protocol processing function module, and the voice users of the entire EPON are managed according...

Abstract

The invention provides a method and device of voice multiple protocols connection in Ethernet network passive light network; it builds chain to PSTN network based on the V5 operation; or if the type of operation is judged to VoIP operation based on IP, further judging whether the calling line and dialed line are at the same PON network, if in the same PON, the function of voice communication between PON is realized by medium substitute, if not in the same PON, the voice flow can be transmitted point to point. The invention resolves EPON narrow voice connection, and problem of transition from PSTN to NGN.

Description

technical field [0001] The invention belongs to the field of optical fiber communication, and in particular relates to a method and a device for realizing multi-protocol uplinking of voice services based on Gigabit Ethernet-based passive optical network (EPON). Background technique [0002] PSTN network is an inseparable network in which the business layer and the call control layer are closely combined. Although the program-controlled telephone exchange based on circuit switching can provide high-quality voice and value-added services for the majority of users, it still has huge limitations. The types of services are single, and when a new service needs to be provided, it is necessary to transform and upgrade the switches of the entire network, which is difficult to implement, takes a long period, and costs high. The emergence of the Internet has changed the situation that a single network provides a single service, and it provides users with an open application environment...
