The ADTRAN HTU Nx64 is an easy to use T1
HDSL network termination unit. The HTU

Nx64 provides a digital interface between T1
HDSL and the user’s Data Terminal Equip­ment (DTE). The HTU Nx64 is an ideal
solution for such applications as LAN to LAN
bridging, Frame Relay circuit termination,
and video-conferencing. The HTU Nx64 can
be deployed as either a remote unit in opera­tion with an ADTRAN T1 HDSL central office
unit (HTU-C) or in a point-to-point configu­ration with another HTU Nx64 in limited
distance campus configuration.

Housed in a compact, durable plastic
housing the HTU Nx64 supports data rates
from 56 kbps to 1.536 Mbps at Nx56 or Nx64
kbps. The HTU Nx64 provides both a V.35
and a V.11 interface for connection to the
end user’s DTE equipment.

Network Connection (Configuration 1)

Configuration, testing, and performance
monitoring is accomphlished via a user
friendly front panel interface. Complete
configuration and performance information
is available from the front panel keypad and
a two-line by 16-character LCD display. The
front panel interface can also be used to
invoke local and remote loopbacks with or
without 511 bit error rate testing. The HTU
Nx64 also supports configuration and
performance monitoring through a rear
panel control port using a VT100 terminal
emulation.
