System Components
The standard components of the AS4000 system include the shelf,
power modules, a System Manager and application modules.
AS4000 Shelf
Types
There are two types of shelf units for the AS4000:
• AS4004
• AS4011
NOTE: All application modules are interchangeable between the
AS4004 and AS4011 shelf units.
AS4004 Shelf The AS4004 is the four-slot version of the AS4000 chassis. It comes
standard with one System Manager which controls all programming
options and one power supply module which drives the system.
The AS4004 accommodates up to four application modules with
their rear interface modules, and allows for an optional redundant
System Manager.
The AS4004 permits the use of many combinations of application
and interface modules. For example, install four Quad DS-1
modules and the AS4004 can be used as a sixteen-port DACS.
AS4011 Shelf The AS4011 is the eleven-slot version of the AS4000 chassis. At
minimum it comes with one System Manager module for control
and programming options, and one power supply module. An
optional redundant System Manager and redundant power supply
module are also available.
The AS4011 accommodates up to eleven modules, which provide
for the insertion of up to eleven different application and rear
interface modules. In the basic configuration, the AS4011 can be
used as a forty-four port T1 DACS, or several channel banks within
a shelf unit.

Application
Modules
The AS4000 application modules can access the TDM bus, the ATM
bus, or both, depending on the module. This modular approach
provides cross-connectivity to a variety of communications
applications.
The application module consists of two cards. The front
application card and the rear interface card. The front application
card contains the switch-bus interface circuitry and control-
processor functions.
