Introduction
The PRISM 41TDM (Time Division Multiplexer) is the ideal solution for internal
networking and frame relay access to a local area network (LAN) or other data
applications. It offers a managed interface into standard DDS service supporting
both synchronous and asynchronous data.
Delivered in a standalone housing, the unit can be installed and operated on a
desktop or in a rack mount configuration with full access to configuration, status,
and diagnostic features available through a front panel screen using the front panel
control buttons and indicators or through a functional menu structure using a
VT100 interface.
The PRISM 41TDM contains an embedded SNMP agent allowing access directly
from a LAN. This agent supports MIB-II and proprietary DDS and TXPORT
MIBs providing information specific to the unit’s operation. The unit also supports
terminal sessions via Telnet.
The TCP/IP connection can be accessed through the standard SLIP interface or
through the optional Ethernet or Token Ring interface. The unit supports two DTE
ports. Ports A and B are software selectable for V.35, RS-232, or EIA-530.
The PRISM 41TDM has diagnostic features allowing quick and easy
troubleshooting. The unit responds to all standard loop codes from the telco and
can initiate remote V.54 loopbacks. An internal BERT can be used for testing. Line
conditions are monitored and reported through the front panel, a user connection to
the terminal interface, a Telnet connection, or through SNMP.
The dial backup feature ensures that critical data applications are secure. The
dedicated line service is monitored for trouble conditions. When a line failure is
detected, the unit establishes a dial connection through a backup port. Once the
backup link is up, the unit routes the customer data through the switched service.
When dedicated line service is restored, the unit can automatically change back.
The dial backup port uses an internal basic rate ISDN terminal adapter.
