Chapter 5. CSS32 External Coax Subsystem
What is the External Coax Subsystem?
The CCA-3074 does not support coax ports directly attached to
the platform. To accommodate coax connectivity, an external
CSS32 Coax Subsystem can be interfaced to the CCA-3074.
The external CSS32 Coax Subsystem is a Visara LINCS based
product. The CSS32 communicates with the CCA-3074 over an
IP network using TN3270E protocol for display or LMU
sessions, and using LPD/LPR protocol for printer sessions. The
network connection can be as simple as a RJ45 crossover cable
interconnecting the two platforms mounted in the same 19” rack
or the two platforms can be remotely linked through a corporate
Intranet or even across the Internet (preferably through a VPN).
The relationship between the CCA-3074 and its satellite(s) does
not have to be one on one. That is, one CCA-3074 can support
multiple Coax Subsystems, and a single Coax Subsystem can
communicate with multiple CCA-3074s.
CSS32 Factory Default Configuration
The CSS32 comes with a standard factory default configuration.
This configuration is designed to support the CSS32 attached to
the CCA-3074 through a crossover cable. The default
configuration will support up to 31 coax display or LMU sessions
(one session for each of 31 coax ports) and one printer session.
For more complex requirements for the CSS32, changes to the
factory default configuration will be needed.
For more details about the specifics of the factory default
configuration of the CSS32 please refer to Appendix A in the
CCA-3074 Installation and Configuration Manual.
