Pcm1 And Pcm 2 Bipolar Violation (Count And Status) Measure - AMERITECH AM8a Instruction Manual

AM8a Instruction Manual
There are two filters available for noise weighting of the noise measurement. The FLAT filter
will have 0 dB of attenuation of the noise on the line up to 3500 Hz. The CMSG filter has
weighting characteristics that are suitable for voice circuits.
6.8 PCM 1 and PCM 2 BIPOLAR VIOLATION (COUNT AND STATUS) MEASURE
There are two count (CNT) measure displays for the number of Bipolar Violations, Frame
Errors, CRC errors, Slips, Yellow, and Blue alarms.
Two additional STATUS displays indicate if BLUE or YELLOW alarm conditions have occurred.
These displays are for measurements taken at the PCM1 or PCM2 TX or RX jacks and are
shown in the order of MENU up arrow selection:
PCM1 : BPV FERR CRC SLIPS YELLOW BLUE
CNT 512
PCM1 :
STATUS :
PCM2 : BPV FERR CRC SLIPS YELLOW BLUE
CNT 64
PCM2 :
STATUS :
Sub-sections 6.8.1 through 6.8.6 describe each measurement on the CNT displays, and sub-
sections 6.8.7 and 6.8.8 describe the measurements on the STATUS displays.
6.8.1 BPV: counts in increments of 64. This results in a change for every 64 BPV
occurrences. A BPV occurs when two consecutive "1" pulses have the same polarity.
