THE 6100 CSS
The 6100 CSS uses a flexible combination of hardware and software
to connect Tandem NonStop systems to each other, to other
manufacturers' computers and networks, and to a variety of
terminals and other devices. ATP6100 is the software interface
between the GUARDIAN 90 file system and asynchronous subdevices
that are attached to the 6100 CSS by point-to-point links. This
section contains a summary of the components of the 6100 CSS.
For a more detailed description, see the Introduction to the
Tandem 6100 Communications Subsystem .
6100 CSS Architecture
The six implementations of the 6100 CSS combine hardware and |
software components to provide fault tolerance and flexibility |
in choosing the number of communication lines and types of |
protocols. The implementations of the 6100 CSS are as follows: |
• 6105 Communications Controller (6105 CC)
• 3605 Communications Controller (3605 CC) |
• 6106 Asynchronous Communications Controller (6106 ACC)
• 3606 Asynchronous Communications Controller (3606 ACC) |
• Dual-Port Communications Interface Unit (DPCIU)
• Single-Port Communications Interface Unit (SPCIU)
