TEST MODE FUNCTION DIAGRAM
IMPORTANT!
Any digital or electronic telephone button
can be activated from the remote terminal
at any time while in the Test Mode (even
while the end user is using the telephone).
Therefore, caution must be used to prevent
service interruption or interference. The
Test Mode provides status tests to check
whether or not a station or CO line is in use.
The status checks should always be made
before performing other tests.
10.10 CO Line Testing
10.11 To test CO line transmission, two or three
CO lines must be available at the remote site (see
Figure 5).
10.12 CO line testing is accomplished by using all
of the following three methods:
1) Call station B at the remote site via the STRATA
DK system and then place the line on hold
(transmission is checked at the remote site via
Music-on-Hold).
2) Establish a talk path between the two remote
stations (B & C) via a CO-to-CO connection
through STRATA DK.
3) Establish a talk path between a remote station
and the time or weather service via a CO-to-
CO connection through STRATA DK.
10.13 The procedures in the tables provide ex-
amples of the types of tests and functions that can
be accomplished with the Test Mode. These proce-
dures do not cover all the possible tests that can be
performed remotely; however, by using the prin-
ciples given, other tests are possible.
