ADTRAN 6540 SHDSL Specification

DESCRIPTION
The AC powered ADTRAN 6540 SHDSL 2-Wire/4-Wire NTU (P/N 1230001L1) functions as an
interface between the SHDSL network and the Data Terminal Equipment (DTE) for 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
units in a point-to-point limited distance campus configuration, with one 6540 configured to "LT"
mode.
COMPLIANCE
EN 300 386-2; IEC 60950/EN 60950/AS NZS60950; S016; S043.2; ITU K.21 Enhanced; Telstra 1555
FEATURES
The 6540 has the following features:
♦
Housed in a standalone plastic case
♦
Provides four front panel recessed pushbuttons, and eight front panel LED indicators
♦
Provides 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 2-Wire/4-Wire NTU Product Series Installation and Maintenance Practice, P/N
61230001L1-5)
PUSHBUTTON FUNCTIONALITY
Pushbutton Description
PORT SELECT Press the
PORT SELECT
following order: No Port, Nx64k, G.703, SHDSL.
LOCAL LOOP/ If a port is selected, and a Bit Error Rate Test (BERT) is not in progress, press the
ERR INJ
button to initiate or terminate a local loop on the selected port. If a BERT is
LOOP/ERR INJ
in progress, press the button to inject a single bit error.
REMOTE LOOP If the SHDSL port is selected, press the
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).
If a port is selected and there are no local loops, press the
BERT
BERT on the selected port.
