Chapter 5 - Commands
&T6
Test Mode 6
Test Mode 6 is the Remote Analog Loop test which
causes any data from the composite link to be
echoed through just the analog half of the internal
modem back to the link. The function of this
command is similar to Test Mode 5 except it checks
only the modem’s analog circuitry. This test is not
used if your MultiMux is configured with a DSU.
&T7
Test Mode 7
Test Mode 7 is the Switch and LED operational test.
By running your MultiMux in this test mode, you can
switch the eight DIP-switches and verify that they
work by corresponding LEDs being lit.
&T8
Test Mode 8
Test Mode 8 is the Non-Volatile Memory test. Its
function is to check the proper operation of the
MultiMux’s battery backed storage of operational
parameters. This test will overwrite the stored
parameters.
&T9
Test Mode 9
Test Mode 9 is the Watch-Dog Timer test. This test
checks the MultiMux’s Watch-Dog circuitry. The
function of the circuitry is to return the mux to normal
operating mode if, for some reason, its operation
becomes erratic.
&T10
Test Mode 10
Test Mode 10 is the internal 9600 bps composite
modem memory test. When operating properly, this
test displays cycle counts of completed read/write
cycles on the system supervisor display console.
