Description
Technical field
The invention belongs to communication equipment field, particularly a kind of digital switch.
Background technology
Digital switch is for traditional analog switch.User class switch (Private Branch Exchange), i.e. the telephone services network of intra-company's use, internal system extension subscriber shares the outside line of some.Traditional PBX utilizes Circuit-switched principle to realize the function of group telephone, IP PBX then uses ICP/IP protocol, utilize the principle of packet switch, the convert information such as voice and image are the binary byte represented by 0 and 1, achieve identical function over ethernet, so IP PBX is digital switch based on the PBX of IP agreement in other words.
IP PBX switching system realizes the functional unification of computer network and telephone exchange, plays an important role in the communication industry of 21st century.In IP PBX network system, each telephone terminal adopts IP mode to carry out data communication, can not only converse, can also realize the transmission of text, data, image, telephone network and computer network are unified into an entirety, realize the teleworking in local area network (LAN).Particularly will give full play to its powerful resources advantage in remote Collaborative Commerce, teleworking, for business associate, work restructuring bring convenient.Control centre in IP PBX local area network (LAN) according to the concrete condition outside intra-office, can manage computer network, telephone network, reaches resource-sharing effectively.By Internet between the IP PBX net of different regions, telecommunication, teleworking and ecommerce can be realized.Traditional PBX utilizes Circuit-switched principle to realize the function of group telephone, and IP PBX then employs ICP/IP protocol, utilizes the principle of packet switch, achieves identical function over ethernet.Fig. 1 shows a typical IP PBX applied environment topological diagram, wherein IP PBX external member contain an integrated console software, one support the PSTN gateway of H.323 agreement and multiple Ethernet Phone, and optional oppositely gateway (Reverse Gateway).Control desk software is the core of IP PBX, and it can the extension (Extension Number) of configuring telephone, function button and call management and routing policy; PSTN gateway is used for realizing communicating of IP network and legacy circuit-switched telephone network, completes phone incoming call and the exhalation of heterogeneous network; Reverse gateway is used for as traditional analog telephone and facsimile machine service.
When user picks up the telephone calling the opposing party, dialing word string and order are transmitted to control desk software by system automatically, locate the address of callee and accept call request by it.Once call setup gets up, follow-up voice flux just can directly caller and called between transmission, again through control desk, time delay need not be effectively reduced.
H.323 client (as Netmeeting user) in a network can be conversed with other phone equally, and before connecting, it needs the extension dialing the other side, connects after arriving control desk again.If subscriber engaged, a busy-back signal can be returned or directly the voice mail of callee, the concrete facilities must seeing the other side are transferred in calling.
IP PBX also can exchange by artificial circuit, calls among traditional telephone network from IP network.
