CAS-2000 COMPREHENSIVE APPLICATION SYSTEM
3
DS3 Test Access Capabilities
The CAS-2000 supports DS1 testing
from a 3/1 Wideband DCS. The system
supports two single Facilities Access
Digroup (FAD) or Dual FAD
interfaces providing full support for
monitor and split access for up to two
DS3s per stand–alone configuration.
Additional access capability can be
provided using additional subassemblies.
IP connectivity
The CAS-2000 provides IP connectivity
while preserving X.25 communi-
cations, which allows service providers
to migrate easily to a central office
WAN configuration that meets their
budget and schedule.
Scalability
Once installed the CAS-2000 based
DS1 entry level solution can be fully
expanded to support up to 8 additional
T3AS shelves in any combination for
DS3/1/0 DCS/TAU based testing or
DS3/1 in-line test. The CAS-2000 has a
common OSS and EMS interface for
up to 8 additional T3AS shelves in any
combination.
Remote software downloads
With the CAS-2000 remote software
download functionality, technicians
no longer need to visit local sites to
upgrade each system. This capability
greatly reduces field support costs and
allows rapid deployment of T3AS
features and enhancements.
DS 1 Testing Capabilities
Optimal DS1 testing capability is
provided in a compact solution. The
CAS-2000 supports up to 16 single
FAD or 14 Dual FAD DS1 tests. The
HiCAT module provides single or dual
FAD testing of up to eight (8) signals.
The DS1 Access/Test (AT) module
provides two (2) single or dual DS1
tests per module. Up to two modules
may be added to provide continuous
non-intrusive performance monitoring.
Additional test capability can be
provided using additional subassemblies.
Reduced space requirement
The CAS-2000 is a compact 2U high
shelf. The shelf is self-contained
including a power supply, processor
and utility module and 3 slots for
adding test and interface modules.

Distributed architecture
Simplified architecture with the Compact Administration Shelf
The CAS-2000 is cost-effective to deploy with stand-alone shelves (shown in figure 1), eliminating the need to implement
complicated and costly T1 administration links.
