DESCRIPTION

The AC Powered 6540 SHDSL 2-Wire/4-Wire NTU (P/N
1230001E1) functions as an interface between the SHDSL network
and the Data Terminal Equipment (DTE).

The 6540 supports applications such as LAN-to-LAN bridging,
Frame Relay circuit, and PABX termination.

The 6540 is designed to be used either as a remote unit to the

®

ADTRAN Total Access

3000 multiservice platform, or as a pair of
units in a point-to-point limited distance campus configuration,
with one 6540 configured to “LT” mode.

FEATURES

The 6540 supports the following features:

• Housed in a standalone plastic case

• Provides four front panel recessed pushbuttons, and eight

front panel LED indicators

• Provides rear panel SHDSL, G.703, and/or Nx64K ports, and

a local management port

• Provides a rear panel connection for local AC power

• Provides bad splice protection using the ADTRAN

proprietary Runtime TScan™ 2.0 splice protection feature (for
more information on this feature and how to locally manage
TScan, refer to the SHDSL NTU, 2-Wire/4-Wire Product Series
Installation and Maintenance Guide, P/N 61230001E1-5).

order: No Port, Nx64k, G.703, SHDSL.

If a port is selected, and a Bit Error Rate Test (BERT) is
not in progress, press the LOCAL LOOP/ERR INJ
button to initiate or terminate a local loop on the
selected port. If a BERT is in progress, press the but­ton to inject a single bit error.

If the SHDSL port is selected, press the REMOTE

button to place or remove a remote loop on the

port by sending a EOC request message to the LTU
(or NTU in campus mode). If the Nx64K port or G.703
port (with only one service defined) is selected, press
this button to place or remove a remote loop on the
selected port's single data service by sending respec­tive inband loop up or loop down patterns to the far
end (in the associated data service timeslots).

MAINTENANCE

The 6540 does not require routine hardware maintenance for
normal operation. Do not attempt repairs in the field. Repair
services may be obtained by returning the defective unit to
ADTRAN. Refer to the warranty for further information. Field
support for software is provided through upgrade facilities.
