Flexible Network Management and Maintainability
Several network management methods are available for the ATLAS_800PLUS,
including SNMP support. VT 100 and Telnet are also offered, 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 manage-
ment privileges. The terminal interface 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 connections.
Additionally, T-Watch PRO, ADTRAN’s Microsoft® Windows®-based GUI man-
agement 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 extensive
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_800PLUS architecture is the ability to cross connect, or
DACS, up to thirty-four T1 circuits. DACSing allows the assignment and redistri-
bution, 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 resources, 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).
