Abstract

I et synkront nett skal kvaliteten av det overførte digitalsignal overvåkes ved digitalsignalfordelere anordnet langs linjen og de fremskaffede data leveres videre til sentralt styrt nettreserve- koblingssystem. Det er kjent & overføre et BIP-8-kodeord (bit-interleaved-parity-8-code) i et STM- 1-signal i veirammehode til en virtuell beholder (VC-4) i en B3-tidssliss for paritetsovervaking fra kilden til mottageren. Dette kodeord blir nå først overført i en fritt tilrådighet stående Z-tidssliss (Z4) i veirammehode som B4- overvåking, behandlet i hver digital- signalfordeler og fra disse på ny matet inn i den utgående linje. Da hver forandring i den virtuelle container (VC-4) forfalsker B3-overvåkingen, ble det innsatt et korreksjonskodeord i en ytterligere Z-tidssliss (Z5) og som opphever forandringen p.g.a. BIP-8-kodeordet i den første Z-tidssliss (Z4). Denne fremgangsmåte er overalt anvendbar i et synkront nett hvor det overføres en virtuell container (VC-4) for 149,72 Mbit/s.
