The PCM Signal Monitor is an instrument for in-service monitoring of the two PCM links forming a first order PCM communication system. The instrument is used for testing CCITT recommended 30/31-channel PCM systems at various levels of the exchange hierarc.
Der PCM Signalmonitor dient der überwachung der beiden PCM Verbindungen eines PCM Systems erster Ordnung. Es ist zum Test von 30/31- Kanal PCM Systemen nach CCIT ausgelegt. Verschiedene Ebenen mit unterschiedlichen Kodes werden untersucht. Das Ger?t besitzt zwei identische Eing?nge zur überwachung und Messung der relevanten Parameter. Die Bit- Rate betr?gt nach CCIT G.703 2048 kbit/s 100ppm. Zur akustischen überwachung des Telephonkanals ist ein Lautsprecher eingebaut.
The PCM Signal Monitor is an instrument for in-service monitoring of the two PCM links forming a first order PCM communication system. The instrument is used for testing CCITT recommended 30/31-channel PCM systems at various levels of the exchange hierarchy where different codes are used. Two identical inputs for monitoring * of the signal and alarm conditions; * of frame alignment signal error rates * telephone channel signal (8bits) * the signalling (4bits) * the channel time slot 0 and 16 and for measuring of the * frequency of the incoming bitstream * telephone channel signal peak code * telephone channel signal analog level * analog output of the telephone channel signal * audible output of the telephone channel signal Various LEDs monitor conditions and detect errors Bit rate of the input channel is: 2048 kbits/s 100 ppm; built- in speaker for supervising the telephon channel.
