The IP-SLM is software emulation of the BNS BX.25
interface that is also known as the Synchronous Line
Module (SLM).The IP-SLM application allows low cost and
high density access points to terminate BX.25 interfaces
common to Network Elements.The result is significant
cost savings and administrative simplication.The IP-SLM is
also a migration vehicle which enables the reduction or
elimination of proprietary network components for the
Network Element support functionality.
What are DT-6061 and DT-6160?
The DT-6061 and DT-6160 are embedded Network Processors which
applies customer specific protocol operations (protocol
translation and termination) of network connections
that require such a function in a distributed network.
What is IP-SLM Application?
The IP-SLM is an application which operates on the DT-
6061 embedded network processor. The DT-6061 and DT-6160 has
no endpoint interfaces for the BX.25 network
elements.These may be provided in many ways.
Similarly, the Operations System resides on the BNS
network. It requires a BNS UMI (Universal Mediation
Interface) module to communicate with the IP-SLM
application.There is one connection to the OS, and one
connection to the BX.25 port for each network
In the first diagram, the IP network may be a simple hub if
a private network is desired.The DT-4000 ports are used
to connect the BX.25 network elements.These may be
co-located with the DT-6061 or DT-6160, or may be co-located with
the Network Element, as is required.The UMI provides
the connectivity to the Operations Systems.
