Parameter reference Alphabetical Reference
Syntax: GET PMTOT:ALLTOT:x
BERT
Activates a bit error rate test (BERT) on a T1 line. The BER test sends a data pattern and
measures the bit error rate on the selected time slot. Possible values are:
• OFF (default): terminates the BER test.
• QRSS (quasi-random signal source): activates the BER test and sends a QRSS pattern
during the BER test.
• ALT10: sends a 10101010 pattern during the BER test.
• 2047: sends a 2047 test pattern during the BER test.
Note that you cannot perform a BER test and a loopback test simultaneously.
Configuration group: T1CFG
Syntax:
(GET/SET) T1CFG:BERT:X:(QRSS/ALT/2047/OFF)

BES
BES (bursty errored second): indicates the total number of seconds with more than one and
fewer than 320 CRC-6 (ESF), BPV (D4/D-frame), or CRC-4 (E1) errors.
Configuration group: PMCUR, PMTOT, PMINT, FARPMCUR, FARPMTOT, FARPMINT
Syntax:
GET (PMCUR, PMTOT, FARPMCUR, FARPMTOT):x
Syntax: GET (PMINT, FARPMINT):x:(0-95)
CLK
Specifies whether the data port clock is inverted. DTE clocking usually requires a Normal
setting. If synchronization problems occur, specify the clock is inverted. Possible values are:
• NORMAL (default)
• INVERTED
Configuration group: DPCFG
Syntax:
(GET/SET) DPCFG:CLK:1:(NORMAL/INVERTED)
