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."
