TSU ACE Features

A DS1 interface and an Nx56/64 DTE serial interface port.

Easy configuration capabilities using simplistic menus displayed 
in a liquid crystal display (LCD) window operated by a front pan-
el keypad. 

Timing is selectable from the network, from the Nx56/64 DTE 
port, or internally.

All ones, all zeros, 511, 1:8 and QRSS test patterns.

Extensive self-test and monitoring provides assurance of proper 
operation.

Flexible channel allocation (any starting channel and alternate or 
contiguous).

TSU ACE Interfaces

The TSU ACE is equipped with two interfaces: 

Network DS1 interface 

per AT&T 62411

 and 

Nx56/64 serial V.35 high speed interface

.  See Figure 

1-3 and the following descriptions in this section.
