Access System 2000 Overview
Access System 2000 (AS2000) is a uniform system that provides
multiple access interfaces to network services for voice, data, and
video applications. The AS2000 is a bandwidth manager of Level 1
digital services. The Advanced Communications Engine (ACE)
architecture brings the bandwidth management capabilities of the
AS2000 to Level 0 channels (DS0 and E0) and Level 3 channels
(DS3).
AS2000 Concept
The AS2000 system is modular by design, providing different types
of data, network, and management ports. The system’s application
components can be managed individually or through a controller
card, locally or remotely. End-user applications include Local Area
Networks (LANs), video conferencing and imaging, digital voice,
and remote terminal-to-mainframe connections.
An AS2000 system consists of one or more nodes. An AS2000 node
is a combination of up to four shelf units, providing network
support for private networks, virtual private networks, FT1, T1,
FE1, E1, T3, and ISDN PRI. For network management, the Access
System 2000:
• Generates and stores non-service-affecting T1/E1 circuit
performance data for circuit analysis and maintenance.
• Generates alarms for fault conditions from incoming
network/equipment signals, and reports the alarms to the
AS2000 application.
• Stores operator-defined configuration settings required for
network and equipment interfaces.
The AS2000 Advanced Programmable Architecture (APA) enables
new features and firmware upgrades through local or remote
downloads. The download process uses File Transfer Protocol
(FTP) or the Access Manager 2000 program, depending on the
controller module used.

AS2000 platform.
