Embodiment approach

[0010] The protocol stack data goes through the control plane of the device, which is mainly used by the network management, and goes through the DCC channel of SDH. Since only the driver of the DCC channel is provided, the current protocol stack can only use the DCC channel. Now we need to provide a 64K business telephone in the ring network composed of SDH equipment, using the E1 bytes in the regeneration section overhead, which are respectively used as business telephone connections between various network elements in the ring network, which is often called EPHONE. EPHONE data is essentially a UDP datagram. Voice data is included in the datagram. It needs to be forwarded through the protocol stack three layers to realize the intercommunication of the phone. Therefore, the protocol stack is required to use the E1 channel and use the E1 channel independently to transmit EPHONE data, that is, EPHONE data can only go through the E1 channel of SDH through the third layer of the ...

Abstract

The invention relates to communication area especially IP phone. Function of official telephone is implemented on SDH device by using general IP phone. (1) One route of 64 k official telephone is provided in ring network constituted by SDH devices; (2) E1 byte in overhead of regeneration section is as official telephone connection between network cells in ring net, UDP datagram including voice data packet are built; (3) protocol stack transfers EPHONE data through E1 channel, i.e. EPHONE data through protocol stack three layer forwarding can be passed through E1 channel of SDH only; (4) through configuration, based on source IP address, protocol stack identifies EPHONE data; device through OSPF finds route of ring net; (5) in forwarding EPHONE data, channel inversion is carried out from DCC to E1 channel of SDH. The invention is suitable to implementation of official telephone on SDH device based on TCP / IP.

Description

Technical field: [0001] The invention relates to the communication field, especially IP telephone. Background technique: [0002] Most of the service calls on SDH equipment are realized by providing service call interfaces on the equipment, which increases the cost of the equipment. With the emergence of IP telephony, voice data can be compressed and packaged into IP packets for transmission on the IP network, and then decompressed and converted into voice data after reaching the receiver. If the control plane of SDH equipment is based on TCP / IP, voice data packets can be transmitted through routing. [0003] The purpose of the present invention is to: provide a kind of using software to realize the transmission of voice data packet, a kind of method that realizes the service telephone on the SDH equipment with IP phone to realize the conversion between voice data and IP bag. Invention content: [0004] a. First, provide a 64K service telephone in the ring network compos...
