For example, the channel list (@1:3) addresses 3 channels within a
data port and reports 6 values in a comma-separated list, for example,
2.345e5,0,2.33e5,0,2.32e5,5. Each pair of values relates to one
terminal. The first value is the number of received bits, the second
value is the number of erroneous bits (failed bits). One pair is sampled
at the same time, the subsequent pair is sampled some cycles later. In
the example, there are 5 errors counted at terminal 3.
The syntax of the terminal channel list is as follows:
<TermChannelListExpr
>
<TermChannelList>
<TermChannelListElem
>
<TermNr>
<Digit>
On parameter <PSUM>:
Comma-separated list of two exponential float values.
• The first value represents the accumulation of the received bits
count (Accumulated Number of Bits).
• The second value is the accumulation of the the error bits count
(Accumulated Number of Errors) for all terminals of the whole port.
On parameter <TermChannelList>:
Comma-separated list of tuple exponential float values. There are as
many tuples as addressed by the <TermChannelList>. The values of the
tuple are likewise comma-separated.
• The first value of the tuple represents the accumulation of the
received bits count (Accumulated Number of Bits).
• The second value of the tuple represents the accumulation of the
error bits count (Accumulated Number of Errors) for all terminals
of the whole port.
When no parameter provided:
Comma-separated list of tuple exponential float values. There are as
many tuples as terminals contained in the specified port. The values of
the tuple are likewise comma-separated.
• The first value of the tuple represents the accumulation of the
received bits count (Accumulated Number of Bits).
