Frame 8 contains a

protocol parameter

update from the LE to the

AN, in this case to set the

AN's recognition time

criterion for ‘user back on

hook’ to a value

(‘duration type’ = 1)

which is held in some

look-up table in the AN.

This would allow a loop

‘open’ during pulse

dialling not to be

misinterpreted as an on-

hook.
