It is possible to generate BERT+RLB or BERT (from both CO and CPE) in 
multiplexer and E1 and DTE Serial single units. 
The BERT, RLB + BERT can be set only if there is a connection to the FE unit. 

The following are the BERT test patterns that can be selected: 
•  2E15-1 
•  Mark 
•  Space 
•  Alternate 

BERT has a possible Single Error injection only. 
The BERT performance counters are as follows: 
•  Error bits – the total number of bit errors detected 
•  BERT total time – the total time the test is running in seconds 
•  Bert error time – the total number of seconds in which errors have been 

detected – in seconds 

•  BERT Sync Loss – the number of times Sync Loss was detected since BERT 

started to run 

•  BERT result – the number of error bits divided with the total number of data 

bits. This item holds 1 byte for the exponent and 2 bytes for the mantissa 
holding 1 byte before the period and 1 byte after the period 

•  BERT Sync Loss state – the Sync Status while BERT runs. The BERT Sync Loss 

state has the following values: 

 

SyncLoss = 0 

 

 Sync = 1 

•  BERT sync run time – the total number of seconds in which sync have been 

detected – in seconds 

•  BERT total bits – the total number of bert bit. 

 

To select the BERT patterns values for Local and Remote tests: 
1.  From the Diagnostics menu, select Local/Remote Test (Main menu > 

Monitoring > Local/Remote Test). 

The Local/Remote Test menu is displayed (see 

). 

2.  From the Local/Remote Test menu, select BERT. 

The BERT menu is displayed.
