T1 line deployments remain a staple in
service portfolios of most telecom carriers.
However, numerous legacy T1 lines, relying
on older Alternate Mark Inversion modulation techniques, have been replaced by
HDSLx technology. ADTRAN® offers end-toend HDSL4 card solutions for the most
frequently found legacy form factors in
telecom networks — E220, DDM+, and 3192.
Issue 2 of ANSI T1.418 standard for HDSL2
includes a 4-wire TC PAM T1 transport technology called HDSL4. This technology is a
4-wire (2-pair) implementation of the High
Bit Rate Digital Subscriber Line - 2nd
Generation (HDSL2) technology. HDSL4
combines two well-known approaches to DS1
transport, HDSL and HDSL2. HDSL4 provides
a standards-based repeatered T1 transport
technology that remains spectrally compatible with ADSL per ANSI T1.418.
HDSL4 offers improved operating margins,
a good price/performance value, and spectral
compatibility with ADSL in the same binder
group. It allows deployment ranges (without
repeaters) beyond HDSL and HDSL2. Carriers
can avoid replacement of costly repeaters in
areas just beyond the CSA. In fact, HDSL4 is
the only extended reach T1 transport technology that is spectrally compatible with
ADSL (per ANSI T1.418) when deployed with
repeaters.

The ADTRAN HDSL4 solutions include
central office, repeater, and remote cards for
legacy form factors commonly found in
networks.
HDSL4 products provide span powering
voltage (negative only with respect to ground,
–190 VDC nominal, GFI protection less than
5 mA) and meets all requirements of Bellcore
GR-1089-CORE (Class A2), ANSI T1. 418-2002.
The products are NRTL listed to the applicable UL standards.
ADTRAN’s HDSL4 repeaters feature inband loopback control, remote provisioning,
and pass-through control. They are available
in standard T200 and 239 mechanics.
ADTRAN’s HDSL4 units are equipped with
troubleshooting-at-a-glance LEDs that
provide customers with a simple means of
identifying the location of certain faults.
Several new screens have been added to the
craft interface to simplify the trouble isolation
process.
These HDSL4 units are equipped to
support the ADTRAN TScanTM feature. TScan
allows the remote retrieval of circuit diagnostics and performs advanced fault location. For
implementation of TScan, please contact your
local ADTRAN sales representative.
