Telecom measurements

All measurements are simultaneous.

Errors

At 2048 kb/s have error count, average error ratio, error free
seconds, % error free seconds of: bit (64 and 2048 kb/s), code,
frame bit, CRC4, REBE (remote end block error – E bits).

ITU-T M.2100 analysis

ES, SES and availability for maintenance monitoring of transmit
and receive directions. Receive only for out-of-service testing
(includes PRBS defects and anomalies).

ITU-T G.821 error analysis

SES, %SES, ES, %ES, UAV and %UAV (telecom only), percent
availability (datacom only), US, DM, %DM, long term mean error
ratio. Also G.821 Annex D and user-defined thresholds.

Alarms

Alarm seconds and LED display of: AIS, LOS, LOF, CAS MFM
loss, CRC4 MFM loss, remote alarm, remote MFM alarm, pattern
sync loss, octet loss, power loss.

Frequency
Range:

 0 to 9 MHz.

Resolution:

Slips and COFAs

Number of pattern slips in available time and changes of frame
alignment (COFA) are detected and counted.

can be either 10

3

 bits or PRBS length), block error count/ratio,

asynchronous ES, %EFS, clock slips.

ITU-T M.2100 analysis

Control-circuit timing analysis

Graphic display of the status of control circuits RTS, CTS,
DTR, DSR, DCD and Mon (monitor in V.24 mode only).

Delay

Between user-defined start and stop events.

Start and stop events
