HTU Nx64

T1 HDSL Network Termination Unit

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 Equip-

ment (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 opera-

tion with an ADTRAN T1 HDSL central office

unit (HTU-C) or in a point-to-point configu-

ration 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.

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.
