PRONTO ISDN 2 USER S MANUAL V6 1 1 2 PRONTO ISDN 2 MPEG LAYER II CODEC The Pronto ISDN 2 also offers the possibility of working under the MPEG 1 Layer II compression algorithm in the modes most widely used in the broadcast environment This involves a change in the configuration of the equipment as shown in the block layout on the next page There is a fundamental difference to the previous case in that when an MPEG compression mode is chosen only one audio encoder decoder is available This does not mean however that the equipment cannot handle two communications lines the two B channels of a basic access line for example so that using the J52 standard protocols it can send and receive encoded audio at a binary rate of 128 kbps However two codecs working at 64 kbps are not available To summarise when one of the MPEG modes available in the Pronto ISDN 2 is selected dual codecs are not available and the functions associated with line 2 are disabled This leads to two particular case for modes at 128 Kbps When a call is made line 1 another call is automatically made to the same number on line 2 When line 1 is hung up line 2 will automatically be hung up also after a few seconds After a call is established on both lines if the call is cut off on one of the lines the system will try to recover the call by making a call to the same number provided that the call on the other line is not cut off after a timeout o
