The ADTRAN NTU Nx64 is an easy-to-use E1 HDSL network termination unit. The NTU Nx64 provides an interface between E1 HDSL and the user's Data Terminal

Equipment (DTE). The NTU Nx64 is an ideal solution for applications such as LAN to LAN bridging, Frame Relay circuit termination, and video-conferencing. The NTU Nx64 can be deployed in two system configurations:

1) as a remote unit to the ADTRAN E1 LTU central office unit.

2) in pairs in a point-to-point limited distance campus configuration.

Housed in a compact, durable plastic housing, the NTU Nx64 supports data rates from 56 kbps to 1.984 Mbps at Nx56 or Nx64 kbps. A single V.35 or V.11 interface provides connection to the end user�s DTE equipment.

Configuration, testing, and performance monitoring are accomplished with a user-friendly front-panel interface. Complete configuration and performance information is available from the front panel keypad and two-line by 16-character LCD display. The front panel interface can also be used to invoke local and remote loopbacks. The NTU Nx64 also supports configuration and performance monitoring through a rear panel control port using a VT100 terminal emulation.
