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."
