product. The LoopCare product is the evolution of the Lucent Technologies MLT
operations system.
The IP-LTCN can replace a DCN in its entirety. This eliminates a maintenance risk since the DCN
is manufacturer discontinued, with a consequential shortage of spare parts. A side benefit is that
the IP-LTCN will free up the 120 square feet of conditioned floor space taken up by the DCN.
The IP-LTCN supports an enhanced TCP/IP interface to the LoopCare host. This allows
connectivity with the LoopCare hosts using an IP infrastructure. The new LoopCare hosts do not
have either a BX.25 interface to communicate with a DCN, or a fiber interface to communicate with
a BNS/Datakit node. Instead, the LoopCare hosts have implemented a direct
TCP/IP (with RFC 854+885+1123 encapsulation) interface to the IP-LTCN application.
The IP-LTCN application relies on the DT-6X60 redundancy infrastructure for its reliability. The DT-
6X60 infrastructure provides 100% reliability through a 1+1 spare arrangement. The IP-LTCN
implements both the “A” and “B” cabinets of the DCN, and all interface paths of the LCN.
Consequently, the IP-LTCN is the most reliable solution possible for the loop test environment.
11.7 X25PAD
The X25PAD Application eliminates the need, complexity, and expense of specialized X.25
equipment in an IP network. The X25PAD Application allows an X.25/BX.25 device, such as a
network element’s console, to be connected to a synchronous port anywhere in the IP network.
Examples are a port on a DT-4XXX or DT-2020 connected SAM, or an endpoint such as a SAM
port in a BNS/Datakit network that connects to an IP network through a UMI module. X25PAD
Application connections to virtual circuits on an X.25/BX.25 port are provided with a telnet TCP/IP
connection and support both X.3 PAD and Pass-Through functionality on a per virtual circuit basis.
This application can also be used to replace the functionality of the Datakit X25 Pass-Through
DKAP application.
11.8 IP-SLM
The IP-SLM application performs a software emulation of the BNS BX.25 interface (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 simplification. The IP-SLM is also a migration vehicle, which
enables the reduction or elimination of proprietary network components for the Network Element
support functionality.
Recent changes in requirements by Telcordia Technologies for the volume of information collected
from network elements have generated the need for higher speed BX.25 links. The most cost
effective way to meet this need is with the IP-SLM application. Synchronous line speeds as high as
56 Kbps are supported.
