Abstract

PURPOSE:To realize voice storage communication transmitting a voice data only and not transmitting a silent data by providing a timing means generating a timing signal corresponding to the time length of a voice packet, a counter means counting the number of the timing signals and a means generating the information inserted between pieces of information relating to adjacent voice data. CONSTITUTION:A timing circuit 2 started at each reception of a storage service voice packet generates the timing corresponding to the voice packet time length set by the circuit and the number of silent packets existing continuously between voice packets based on the timing is counted by a silence counter 3. Then a silence counter extraction circuit 42 extracts the count value of the silence counter 3 and the count value of the silence counter 3 is reset at the same time. The count value of the silence counter 3 is edited into silence information and the result is added to voice information and the added result is set to a data storage circuit 45 together with silence/voice data display.

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to voice information storage means used in a packet switching network. In particular, the International Telegraph and Telephone Consultative Committee (CCIT)
T) Applies to packet communications using ink faces specified in Recommendation X75 or Recommendation X25.

[Conventional technology]

Instant voice communication has been realized in packet-switched networks as a communication method that does not send silent data over trunk lines, but voice storage communication has not been realized. As is well known, voice storage communication significantly improves line usage efficiency, and it is desired that this can be applied to the above-mentioned interface.

[Problem that the invention seeks to solve]

The present invention eliminates the above-mentioned limitations, and provides voice storage communication in which only voice data is transmitted as voice packets and no silent data is transmitted over a relay line having an X75 or X25 interface recommended by the International Telegraph and Telephone Advisory Committee. The purpose of the present invention is to provide a voice packet storage device that realizes the following.

[Means for solving problems]

The present invention is based on International Telegraph and Telephone Advisory Committee Recommendations X75 and
A voice packet storage device for a voice packet communication network that has an interface condition defined by any one of 25 and 7 and is configured so that voice data of voice packets is transmitted and silent data is not transmitted, and the above-mentioned problem is solved. As a means for solving this problem, a timing means (which generates a timing signal corresponding to the time length of the voice packet and divides the time length between adjacent sound data by this timing signal) is provided.
2), counter means (3) for counting the number of timing signals, and means (42 and 43).

[Effect]

When the sound data of the voice packet for the storage service arrives, the timing means (2) is activated, and the counter means (3) detects the voice packet that can be regarded as silent data corresponding to the time length between adjacent sound data. The number is counted, the silence information related to this counting is edited by the silence data editing addition circuit (44), and the accumulated data editing circuit (41)
) is added to the voice presence information edited by the data storage circuit 4.
Set to 5. At the same time, the counter means (3) is set.
