company seeks a solution to migrate their 3270
mainframe-to-terminal leased-line environment to a complete Ethernet LAN
environment.
The Customer
AT&T
Data Center in Denver Colorado supported nation wide network connectivity
for other AT&T business units.
The Problem
The AT&T Denver
facility needed to migrate their 3270 mainframe-to-terminal leased-line environment
to an Ethernet LAN environment with minimal downtime and keeping
their legacy desktop equipment. Within this migration AT&T didn't
want to lose any of the features (SDLC, BSC,
LPR/LPD, RTM, Remote Configuration, ...) they currently had and wanted to keep
in place their familiar desktop environment.
The SSI Solution
SSI already had a solution for this migration called LANPanther. LANPanther was
architected, designed, developed, and tested by SSI Engineers. It used the latest
industry standard processor technology, operating systems and network cards on the market.
LANPanther
is an advanced hardware/software consisting of a standard
Pentium System, UnixWare, Synchronous cards(s),
Ethernet/Token Ring card(s) and LANPanther software. The
solution provided SDLC and/or BSC to TN3270 protocol
conversion, as well as LPR/LPD printer support for existing
3270 cluster controllers and their respective devices . . .
devices that cannot be connected directly to a TCP/IP network.
With LANPanther, traditional
devices such as 3270 displays and printers can have
LAN-attached 3270 host access until a transition to a pure
Client/Server environment can be achieved. Because LANPanther
appears
as a Front-End Processor to the CU devices, their existing
configuration was not affected.
The complete LANPanther software was developed by SSI and
included the following:
- Unix drivers to support the Arnet 570i Synchronous and
SMC TokenCard Elite card(s)
- Unix application software for SDLC or BSC to TN3270E
protocol conversion, TN3270 RTM, LPD, Mail and Web services,
and Administration
- Motif and Java graphical software application to
administer the system with an on-line help system. The
Java application was used to remotely to administer the
system from a browser.
