Compliance
Table 1
shows the compliance codes for the 2W/4W
SHDSL LTU. The 2W/4W SHDSL LTU is NRTL
listed to the applicable UL standards. The 2W/4W
SHDSL LTU is to be installed in a restricted access
location and in a Type “B” or “E” enclosure only.
This device complies with Part 15 of the FCC rules.
Operation is subject to the following two conditions:
1. This device may not cause harmful interference.
2. This device must accept any interference received,
including interference that may cause undesired
operation.
Changes or modifications not expressly approved by
ADTRAN could void the user’s authority to operate this

Connections
The SHDSL LTU module fits any one of the 1-28 slots
in the Total Access 3000 chassis or any one of the 1-22
slots in the Total Access 3010 chassis. Power and alarm
signals are provided to the card through the backplane
of the shelf.
The G.703 and SHDSL signals are transmitted/received
via the 64-pin backplane amphenol connectors. The
G.703 signal is transmitted to the network side via “Pair
8,” and the G.703 signal is received from the network
side via connector “Pair 7.” The SHDSL signal is trans-
mitted to and from the customer-side NTU via
connector “Pair 2” for 2-wire mode and “Pair 2” plus
“Pair 1” for the 4-wire mode.
