fered, providing detailed system configuration through an easy-to-use
menu system. The terminal interface is secured by six levels of password
protection with varying degrees of management privileges. The terminal in-
terface is accessed locally or remotely using either the EIA-232 Chain In port
on the rear of the unit or the Telnet interface. The 10BaseT interface on the
Base Unit provides an Ethernet connection for SNMP and Telnet connec-
tions.

management system can allow end-to-end management with downstream
ADTRAN T1 products. User configurations can be preserved in non-volatile
memory and duplicated for managing multiple ATLAS implementations.
ATLAS also supports FLASH upgrades for future enhancements. You can
remotely download software using TFTP or XMODEM.
The front panel contains a 2x16 character backlit LCD display and an exten-
sive array of LEDs for alarm and status information pertaining to the system
and the individual modules. A front panel keypad allows navigation
through the menu system and access to system testing.
Several test capabilities allow you to diagnose the health of your T1, PRI, or
BRI circuits without additional test equipment. Standard Bantam test jacks
located on the rear panel also allow you to use external test equipment to
monitor traffic. Tests include local, remote, and V.54 loopbacks utilizing the
511, QRSS, all zeros, and all ones test patterns.
Digital Access Cross-Connect System (DACS)
Inherent in the ATLAS 800
PLUS
architecture is the ability to cross connect, or
DACS, up to thirty-four T1 circuits. DACSing allows the assignment and re-
distribution, or grooming, of any DS0 on any T1 circuit to any other DS0 on
any of the thirty-four T1 circuits in the system. For optimizing network re-
sources, any of five dedicated connection maps can be invoked manually or
automatically, based on the time of day and day of the week (see Figure 1-3).

T1 Bandwidth Manager
As a T1 Bandwidth Manager, ATLAS 800
PLUS
combines the functions of a T1
CSU/DSU, an intelligent channel bank, a T1 Multiplexer, and DACS into a
single platform. The Bandwidth Manager supports a wide range of data ap-
