7.2.3 V.35 OPTIONS
7.3 KEYPAD LOCK
Pressing the Local Loop, Loop Back and the Remote Loop buttons simultaneously for a minimum
of 5 seconds will lock the front panel buttons. The Loop LEDs will flash amber during this period.
Repeating this action will unlock the buttons again.
7.4 AUXILIARY PORT OPERATION
Pressing the Local Loop and Remote Loop buttons simultaneously for a minimum of 5 seconds (the
left most 3 LEDs flash amber) converts the Terminal Port into an Auxiliary Port which can be used
to transport an RS-232 link transparently across the fibre path, independently from the main data
payload. Repeating this action converts the port back to its management function (the 3 left most
LEDs flash red).
