1. General
The TxPORT PRISM 4151 DDS CSU/DSU is the ideal
solution for internal networking and frame relay access to a
local area network (LAN) or other data applications. It is
packaged in a stand-alone housing and provides VT100 and
SLIP interfaces for management.
The PRISM 4151 is easy to install and operate. Full access
to configuration, status, and diagnostic features is available
through the software driven terminal interface connection or
a TELNET and/or SNMP set connection from any host on
the wide area network (WAN).
The PRISM 4151 is an advanced DDS CSU/DSU with an
embedded SNMP agent and TELNET access directly to the
LAN. The SNMP agent allows the CSU/DSU to function
like any other native LAN element. The agent supports
MIB-II and the new DDS MIB that provides information
specific to unit operation. The TCP/IP connection may be
accessed through the standard SLIP interface or through the
optional Ethernet or Token Ring interface.
The PRISM 4151 offers a managed interface into standard
DDS service. It supports synchronous data rates at 56 kbps
for DDS I and 64 kbps clear channel in DDS II. The DTE
supports a V.35 interface. External clocking is supported for
use in tail circuit applications.
The PRISM 4151 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, a
TELNET connection, or through SNMP.
The chapters in this manual are arranged as follows:
1. General - describes product specifications, FCC and war-
ranty information, in addition to TxPORT ordering infor-
mation and customer service telephone numbers.
2. Installation - describes unit mounting, configuration, port
and interface connections, and unit powering.
3. Configuration - describes switch settings and terminal
interface menus and screen settings.
4. Testing - describes the front panel LEDs, front panel but-
tons, and software interface testing features.
5. Operation - describes the alarm types and status features
for the unit.
A. Terminal Interface - describes the features of the unit
firmware including the data fields and menu structure.
B. Pinout Tables - lists the pinouts for each port on the unit.
C. SNMP Agent - defines all MIB entries or responses for
the unit.
