PEB 24901
As the PEB 24901 Quad IEC DFE-T occupies four IOM-slots, the DCL frequency should
be at least 2048 KHz. The SLOT pin assigns either the IOM-slots 0 to 3 to the four
channels 0 to 3 (SLOT pin low), or it assigns the IOM-slots 4 to 7 to the channels 0 to 3
(SLOT pin high).
3.2.1.1
Command/Indicate Channel
The Commandl/Indicate channel (C/I-channel) is used to control the operational status
of the Quad IEC DFE-T and to issue corresponding indications. C/I-channel codes serve
as the main link between the Quad IEC DFE-T and external intelligence. In chapter 3.4.4
status diagrams give information on the commands by which the current operational
status may be left, and on indications issued in all states.
Commands have to be applied continuously on DIN until the command is validated by
the Quad IEC DFE-T and the desired action has been initiated. Afterwards the command
may be changed.
An indication is issued permanently by the Quad IEC DFE-T on DOUT until a new
indication needs to be forwarded. Because a number of states issue identical indications
it is not possible to identify every state individually.
The following example illustrates the use of the C/I-channel in combination with the PEB
2055 (EPIC). It is assumed that the device has been initialized correctly prior to starting
the C/I-code transfer.
