MFC-R2 results
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.
Datacom results
The following sections describe the test results for each of the datacom cate-
gories.
Summary results Table 23 describes the Datacom Summary results.

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