Description

Method and device for multi-party call of collinear telephone based on VOIP

Technical field

The present invention relates to the field of communications technologies, and in particular, to a method and apparatus for multi-party calling of a collinear telephone based on Voice over InterK8 Lnet Protocol (VOIP).

Background technique

The traditional collinear telephone uses a time division multiplexing technique to perform ordinary point-to-point two-party voice calls. The utility model is characterized in that: using time division multiplexing technology, a group of telephones simultaneously share a voice transmission channel, and transmits multiple channels of audio in the same 64K time slot, and the voice signal is encoded into a data signal and inserted into the time slot for performing. Multi-channel audio overlay.

Time Division Multiplexing (TDM), that is, splitting according to the time of transmitting signals, so that different signals are transmitted in different times, and the entire transmission time is divided into a plurality of time intervals (Slot time, TS, Also known as time slots, each time segment is occupied by a signal. TDM implements a circuit to transmit multiple signals by cross-transmitting a portion of each signal in time.

E1TDM supports a 2.048 Mbit/s communication link and divides it into 32 time slots. The time slots are numbered TS0-TS31, and each interval is 64 Kbit/s. In the E1 channel, 8 bits form a time slot, 32 frames form a frame, and 16 frames form a multiframe. In one frame, the time slot TS0 is used as frame synchronization, and the frame positioning signal, the cyclic redundancy check, and the peer alarm are transmitted. The time slot TS16 is used to transmit the associated channel signaling, the multiframe positioning signal, and the multiframe opposite alarm. It is indicated that the remaining TS1-TS15 and TS17-TS31 have 30 time slots for 30 voice channels, and transmit information such as voice or data. 8 bits are transmitted per time slot.

In the later development application, the digital signal processor (DSP) chip is used to superimpose the E1 time slot to realize the multi-user conference function, that is, the E1 time slot is superimposed and then transmitted to the cross array module or E1. The frame module implements simultaneous multi-party calls, but the configuration of this method requires the user to select a cumbersome time slot, which is troublesome.
