ENERAL
Introduction The Verilink PRISM 4051 DDS CSU/DSU provides
the ideal solution for remote DDS I and DDS II
branch access synchronous 56 and 64 kbps data
applications. It is a modular, nest mounted DDS
CSU/DSU and can be managed from a menu-driven
VT100 or by SNMP/Telnet commands from a
Verilink 8100A Site Controller.
The P RISM 4051 is simple to install and operate. Full
access to configuration, status, and diagnostic
features is available through the software-driven
terminal interface connection.
The 4051 unit offers a managed interface into
standard DDS service. It supports synchronous data
rates at 56 kbps for DDS I and 64 kbps in DDS II.
The DTE supports V.35 or RS-232 interfaces.
External clocking is supported for use in tail circuit
applications.
The 4051 has diagnostic features which allow quick
and easy trouble isolation. The CSU/DSU responds
to all standard loop codes from the telco and can
initiate remote V.54 loopbacks. An internal BERT
may be used for testing. Line conditions are
monitored and reported through front panel LEDs, a
user connection to the terminal interface (or a Telnet
connection through the 8100A Site Controller).
The chapters in this manual are arranged as follows.
