9.2.1 Electronic Link Configuration
This section describes the organization of the electronic link switch,
the IMSC004.
In this application the C004 is used simply as a crossbar switch. The
device is connected to 29 links, and can switch any link connected to
any other link connected.
The links connected to the C004 are:
• link0 of all TRAM slots except module0 (module0 link0 is
connected to the host PC via the T2),
• link3 of all TRAM slots,
• eight edge connectors,
• two spare links, which are taken to the patch area.
The connections made by the C004 are controlled by the T2
transputer acting in the role of a configuration processor. The T2 is,
in turn, controlled via ConfigUp (which by default is wired to module0
link1 through the patch area for this purpose). Currently, the only
program which can be booted onto the T2 to alter the C004 switch
connections is the NCS.
The C004 connections are shown in figure 80.
