manual tests will automatically detect and control the
FED when this option is enabled, saving you multiple
trips to the far end after it is initially placed on the line.
The FED should always be connected to ground as
well as the P.U.T. (pair under test).
By connecting the T-R-G/A-B-
E of a customer’s pair
(CPE) to the
customer
side of the FED (blue labeled
connectors; the red labeled connectors are connected
to CO/Exchange side of the pair for pass-through
mode), control signals are sent to the FED by the 6100-
Gfast in order to open/short (or pass through to the
CO/Exchange) the T-R-G/A-B-E connections.
Connect T-R-G/A-B-E as follows for each FED state:
1. For
Pass Through/Exchange Connect
,
connect the T-R/A-B wires to the blue-labeled
Pair1-Cu connectors on the FED (customer
side), and the network side T-R/A-B to the red-
labeled Pair1 Ex-CO connectors towards the
CO/Exchange.
2. For
Open
, connect the T-R/A-B and ground
wires to the customer side of the FED (blue
labeled connectors).
3. For
T-R-G/A-B-E Shorted
, connect the T-R-
G/A-B-E to the customer connectors (blue-
labeled Pair1- Cu) and the ground lead to the
network ground.
Note:
P.U.T.
, in the above diagrams, refers to the Pair
Under Test.

not present or not responding, a
Confirmation
dialogue box will be displayed asking if you
want to disable FED and run the test anyway.
