Connecting AuroraPlus
AuroraPlus can connect to the ISDN for Basic Rate testing on
the S or U interface, and can also be used for analogue
(POTS) testing.
Caution
When connecting to any interface, remember that high
voltages may be present on telecommunications lines.
Connections for testing
Plug the interface cable into the connector on AuroraPlus. The
cables are identified as follows:
• S interface: a black, 4-way cable with an RJ45 plug at
each end.
• U interface or analogue (POTS): a white, 2-way cable
with an RJ45 plug at one end.
Connect the other end of the cable to the equipment under
test.
• S interface: You can connect the cable either way
round. Plug one end into the unit and the other into
an S interface socket on the CPE side of the NT. This
can be a single connection or one connection on a 'bus'
of up to eight sockets.
• U interface: Connect the cable on the exchange or CO
side of the NT, with the NT disconnected.
• Analogue (POTS): connect to a 2-wire line from the
exchange of PBX extension.
