ENERAL
Introduction The Verilink PRISM 3002 is a modular, single port, fractional T1 CSU/DSU
designed to take advantage of T1 integrated access and provide the most
economical fractional T1 access solution available.
The PRISM 3002 allows connection of high-speed digital data to a T1 facility. The
data interface is a standard ITU V.35 and supports port rates from 56 kbps to 1.536
Mbps. Interface to the T1 network is through the 3002's integral ESF CSU which
provides full performance monitoring of the T1 span and is compliant with AT&T
publications TR62411 and TR54016 and with ANSI document T1.403.
The 3002 is equipped with integral dial backup capabilities and can be used with
any vendors switched service device such as an ISDN terminal adapter. Dial
backup can be initiated from stored alarm thresholds or from loss of the T1 facility
For high-density CSU/DSU sites, the PRISM 3002 can be used in conjunction with
the Verilink 8100A Site Controller. The 8100A incorporates an integrated Modular
Embedded Community Agent (MECA) providing SNMP/Telnet management
through a single IP address to access all its controlled units.
LED indicators are provided on the front panel of 3002 alert local personnel of
alarm conditions, loop and test status, and DTE port activity. A test switch allows
local and remote loops to be activated as well as BERT tests. All configuration
parameters of the 3002 are soft selectable from the management system.
The Verilink PRISM 3002 CSU/DSU terminates a broad range of T1/FT1
networking applications. It integrates LAN-to-LAN networking and disaster
recovery in managed or unmanaged environments.
The PRISM 3002 unit provides the T1 network connection through an advanced
integral ESF CSU. Full performance T1 span monitoring allows early detection
and correction of problems before they affect critical applications. The unit
provides a wide range of test functions and loopbacks to aid in rapid fault isolation
and repair and also responds to in-band fractional loop codes to accommodate
fractional T1 service testing by the carrier. An internal BERT allows testing of
both the network and equipment connections.
The PRISM 3002 is compatible with industry standards ensuring access to any T1
provided service and allowing connection of all equipment quickly and correctly.
