Telecom and datacom measurements Telecom measurements Datacom measurements All measurements are simultaneous. 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.
Specifications of options available for both analyzers 8 Mb/s measurements (Option 002) Adds framed and unframed pattern generation and measurements at 8 Mb/s. All specifications same as 2 Mb/s except: Clock: 8.448 Mb/s (internal), 500 kHz to 9 MHz (external). Line code: HDB3. Ternary data input: 8.448 Mb/s ± 100 ppm. 704 kb/s measurements (Option 003) Adds framed/unframed pattern generation and measurements at 704 kb/s. All specifications same as 2 Mb/s except: Clock: 704 kb/s.
Relative frequency and bit slips (Option 010) ITU-T M.2110 and M.2120 analysis (Option 210) 2.048 Mb/s only Measurement start at userspecified time. Summary print of current settings and counts. Measures relative frequency of, and bit slips between, two ITU-T G.703 2 Mb/s signals. Results displayed as +ve and −ve peak wander (UI), cumulative bit slips, frequency offset (ppm) and graph of bit slips (256, 16 UI). Reference input level: 0 to −20 dBm. Connector: BNC 75 ohm, unbalanced. ITU-T M.
