General
1.0 Introduction
The PRISM 3000 supports all data networking needs, from
connection of a single front end processor to shared access
for video, frame relay, and voice. This approach gives the
speed and flexibility of T1 transport through a single point
of control. It may be configured for up to 4 high or low
speed data ports.
Operating the PRISM 3000 is easy, with a choice of three
menu driven interfaces. The front panel LCD display is
described in the ‘Operations’ chapter of this manual. The
RS232 connection to a local or remote terminal is explained
in the ‘Terminal Operation’ chapter. The TxPORT EM8000
network manager may be used for large network control
(refer to the EM8000 reference manual).
The unit provides the T1 network connection through an
advanced integral ESF CSU. Full performance T1 span
monitoring enables early detection and correction of prob-
lems before they affect critical applications. The unit pro-
vides a wide range of test functions to aid in rapid fault
isolation and repair. All the standard loopback functions
may be implemented. The unit also responds to inband frac-
tional loop codes to accommodate fractional T1 service test-
ing by the carrier. An internal BERT is provided for testing
both the network and equipment connections.
The PRISM 3000 is compatible with industry standards to
ensure access to any T1 provided service and to allow con-
nection of all equipment quickly and correctly. Innovative
design eliminates clocking problems on the high speed data
ports. The unit utilizes ‘FLASH’ memory to allow firmware
upgrades in the field. This eliminates the need for taking
units out of service for an extended time or returning units
to the factory for updates.
The unit allows complete control of the DS1 bandwidth with
flexible assignment of DS0 channels, allowing the user to
program bandwidth as needed for each application. For
example, voice bandwidth not required after hours can be
allocated to meet data processing requirements.
The integral Ethernet or Token Ring management option
provides for wide area LAN connectivity. When connecting
local area bridging or routing devices to a T1 network, other
CSU/DSUs are out of the LAN management loop. With the
PRISM 3000, the critical T1 connection point is under con-
trol of the existing SNMP management system, providing
seamless integration of LAN and WAN, and eliminating the
need for a separate CSU/DSU management system.
1.1 Design Highlights
• Three slots for customer application cards:
– Ethernet or Token Ring card with embedded SNMP/
Telnet support
– Dual high speed port cards (V.35 or EIA530,
synchronous N x 56 kb/s or N x 64 kb/s)
– High and low speed combination cards (RS232/ V.35,
RS232 / EIA530, RS232 synchronous)
• Integral ESF/CSU provides full performance monitoring
(meets TR62411, TR54016, and T1.403 standards)
