The Recall button is used in this system as a self-test b utton, and, when pressed,
lights all of the lamps on the MET set and runs the ring er update.
This section refers only to the MET-LINE maintenance that is performed. Note that
MET-LINE maintenance is closely related to, and interacts with, the MET-BD (MET
line circuit pac k) maintenance in some instances. Some of the results of
maintenance testing of the MET line may be affecte d by the health of the MET
Line circuit pac k. This interaction should be kep t in mind when investigat ing the
cause of reports of MET line problems.
There are instances in this section where service states of a station are
mentioned. An explanation of these se rvice states follows:
■Out-of-Service—The port (and station) have b een removed from service.
A busyout of a port cau ses it to be out-of-service.
■Ready-for-Service—Once a port on the c ircuit pack has b een put into
service, the voice terminal must c ommunicate that it is present. The time
between these two events is the time when the terminal i s in the
ready-for-service state.
■In Service—Once the system receives a messag e from the voice terminal
communicating that it is present, the station is put into the in-servic e state.
The terminal can also be forced into the in-service state if it goes off-hook
while it is in the ready-for-service state.
After running the status station command, the status is report ed as either
out-of-service, in-service (as stated in the preceding list), or disconnec t (the
station is in the ready-for-service state).
