2. APPLICATIONS

2.01

Subscriber Drop Testing. For subscriber drop

testing from the central office, PG-Flex is able to

select and connect any subscriber drop to a metallic test pair

at the RT. PG-Flex extends this connection back to the COT

where it can be switched onto the test access bus, or to the

corresponding subscriber line on the COT channel card.

2.02

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.

2.03

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.

2.04

Test access may also be activated through the

RS-232 Maintenance Port located on the front of the

COT Line Unit, using an ASCII terminal.
