Test access may be achieved by placing +116 V
on the subscriber's COT tip lead for 1.5 seconds, then
removing the +116 V. Depending on the configuration of
the PG-Flex system, the selected subscriber drop
(assuming a working metallic bypass pair) will be
connected to either the corresponding COT subscriber line
or to the test access bus.

The test connection will be dropped when -116V
is applied to the subscriber's COT tip for 1.5 seconds, then
removing the -116 V.
