3.Proposed revisions to Recommendation M.110

                        CIRCUIT TESTING

       Add the following sentence at the end of  1.1:

       "Where a circuit uses channel associated signalling, it should be
       possible  to  identify  and   measure   at   the   circuit   access
       points,  the   signal-transmission   parameters,   e.g.   type   of
       signal, sequence, timing, duration, level and frequency."

       Change the end of  1.6 to read:

       "... digital path as possible. With suitable digital  test  equipment,
such digital path access points enable in-service circuit  monitoring  to  be
carried out when, for example, digital paths  are  directly  interfaced  with
digital exchanges or transmultiplexers.

       When the digital path is out of service this same point can be used to 
transmit and receive signals for both digital path and circuit testing."
