		End-to-End Test Results
Results	Reported By 1		Information Displayed
Time:	Local and remote DBM		Running test timer. (The Clr selection resets the timer to 0:00:00.)
Tot Block:	Local and remote DBM		Number of blocks completed. (The Clr selection resets the counter to 0.)
Rx Blk err:	Local and remote DBM		Number of incoming blocks with errors detected, indicating a fault in the
			incoming transmission path. (The Clr selection resets the counter to 0.)
Tx Blk err:	Local and remote DBM		Number of blocks with errors detected at the remote DSU, indicating a
			fault in the outgoing transmission path. (The Clr selection resets the
			counter to 0.)
Rx TimOuts:	Local DBM only		Number of blocks that were not received or acknowledged by the
			remote DSU or DBM. (The Clr selection resets the counter to 0.)
1 Local refers to the test initiator.

Bit Error Rate Test

The Bit Error Rate Test (BERT) is a session- disruptive test that transmits a 511-bit pattern. It analyzes the network circuit. It can monitor the results by putting the remote DSU or DBM into Digital Loopback and checking the returned pattern for errors, or by simultaneously executing a BERT in the local DSU.

The test continues until aborted from the DCP or NMS.

If nondisruptive diagnostics are in effect (if Diag Type is set to NonD), diagnostic data can be disrupted.

To display the results of the test, press F2 to select Displ. The results are shown in Table 4-5. To clear the results of the test and clear the counters to zero, press F3 to select Clr.

Bit Error Rate Test Results

Results	Information Displayed
Time:	Running test timer. (The Clr
	selection resets the timer to
	0:00:00.)
Tot Error:	Running count of bits in
	error; Max, if the maximum error
	count has been reached, which
	is 64000. (The Clr selection
	resets the counter to 0.)
Err Secs:	Running count of errored
	seconds. Errored second is at
	least one error is detected during
	a 1-second time period. (The Clr
	selection resets the counter to
	0.)
