US 5,708,713 A · Method for monitoring a signal to be transmitted via at least one telecommunication link, a monitoring system, a monitor controlling device and processing means

Abstract

Prior art methods used for monitoring, via monitoring means, signals which are to be transmitted via telecommunication links and with said signals each comprising a signalling signal and a content signal, require that the processing means which are required for monitoring are either situated in the vicinity of the monitoring means or must be coupled to the monitoring means via leased-lines. By having the monitoring means generate a further signalling signal, dependent upon a code word related to a signalling signal, and consequently transmitting, dependent upon the further signalling signal, a content signal which is to be monitored to the processing means, a substantial more efficient method is obtained as both means can be coupled via a public telephony network. Furthermore, the possibility arises not only to transmit a content signal which is to be monitored to the processing means but also a signalling signal, especially if the telephony network is a so-called ISDN network which uses one or two B channels and one D channel for each telecommunication link which has been established and has to be monitored.

Dependent claims

A method for monitoring, via monitoring means, a signal which is transmitted via at least one telecommunication link and with said signal comprising at least a signalling signal and a content signal, wherein the method comprises the steps of:

detecting, by the monitoring means, at least one code word situated in the signalling signal so as to form a detected word code;
monitoring, by the monitoring means and in response to the detected code word, at least a part of the content signal;
generating, by the monitoring means and in response to the detected code word, a further signalling signal;
and
transmitting, by the monitoring means and in response to the further signalling signal, the part of the content signal which is monitored to processing means defined by the further signalling signal.
