There are three result categories in the MFC-R2 Signaling application:
– Survey Display displays the forward and backward signaling bits
decoded to line state labels (for example, seize, clear forward, etc.).
– Call States displays call statistics for each channel.
– Line Display displays the current line signaling and/or register
signaling for each receive channel with its associated time stamp.
The following sections describe the test results for each of the datacom cate-
gories.
Table 23
describes the Datacom Summary results.

Definition
Indicates whether an active signal is present (yes/no).
Indicates whether pattern synchronization was detected.
(yes/no).
Pattern synchronization detected since last test restart.
Number of received bits with a value opposite that of the
corresponding transmitted bits, after pattern synchroniza-
tion has been achieved.
Number of times the received pattern is lost relative to the
expected (therefore, internally generated) test pattern.
Number of pattern slips detected since start of test (PRBS
patterns only).
Number of blocks that contained an errored bit.
Number of seconds where the receive clock was
detected. Only appears if using synchronous timing.
Receive clock detected since last restart. Only appears if
using synchronous timing.
Receiver synchronization loss detected since start of test.
Only valid when the Data Loss setting is enabled and only
appears if using synchronous timing.
Number of receiver synchronization losses resulting from
a loss of data. Only valid when the Data Loss setting is
enabled and only appears if using synchronous timing.
Receiver synchronization loss currently detected. Only
valid when the Data Loss setting is enabled and only
appears if using asynchronous timing.
Number of receiver synchronization losses resulting from
a loss of data. Only valid when the Data Loss setting is
enabled and only appears if using asynchronous timing.
