In 2.1.1 the second sentence of the paragraph following the
definition "line access points" has to be changed to read:
"In this case any necessary testing of circuits carried out at ...
(rest unchanged)."
In 2.1.1 the third sentence of the paragraph following the definition
of "line access points" has to be replaced by:
"Circuit tests which involve the sending of test signals should be
carried out from the circuit access point as defined in 2.1.2
below."
Add the following alinea to 2.1.2:
"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."
