If offers a laboratory quality VFTIMS, a fullfeatured BERT, RS-232 and a host of other functions as standard equipment. The BJ08’s versatile signaling features enables it to simulate, test and monitor at almost any point in a hybrid network. It is equally at home at the IAD, gateway, switchroom, PBX closet, customer or carrier DEMARC, in the lab or on the production floor. Its ability to simulate and monitor both sides of a connection makes it anindispensable troubleshooting tool.           Specificaties         Qualify Voice Services: Test the networks ability to transmit distortion free voice in both directions Provides Clarity Merit Score (MOS)     Measures audio level       Measures background noise     Bad MOS Scores: Detect and measure packet loss       Detect and measure voice clips       Detect and measure noise hits     Isolate echo problems: Detect and measure echo       Verify echo cancellation     Verify End-to-End Network Performance and Provisioning Measure network delay   Measure jitter buffer performance     Verify codec type   Measure call completion time (post dial delay)   BJ08 Transmission Features: Level and Frequency (20Hz – 5000Hz)       Noise (Psophometric and 3Khz Flat Weighted)   Noise-to-Ground     Signal-to-Noise Ratio   Return Loss (2– and 4–wire) Frequency Sweep     Dual Tone Gen (level, freq, cadence)   Echo Canceller Disabler Tone   BJ08 Digital Features: 2.048 Mbit/s E1 (PCM30/31, CRC4, HDB3/AMI)   Internal High Stability Clock or Loop     Terminate and dual direction drop, insert or monitor modes   Real time display & cntrl of ABCD bits     aLaw or uLaw encoding       Voltage measurement   Full rate and 64kbit BERT     Generate and detect Alarm       DS0 Loop back with gain control     BJ08 Analogue Signaling Capabilities: Loop Start (contact/battery)       Ground Start (contact/battery)       E&M Types I-V (Send-M, Send-E)       Dry (no supervision)       Wink Detection and Timing       Delay and Immediate Dial       DP, MF, and DTMF addressing     BJ08 Signaling Capabilities POTS, DTMF signaling       R1 (wink start signaling, MF signaling)       R2 (Simple, ITU, Country Spec)       Clear Channel       R2 Protocol Analyzer     Physical characteristics: E1:120/75 Ω       Telset & Butt-Set Interfaces       E1 span status LEDs       Com Port: RS-232 (EIA 9-Pin)       Power 120/240VAC       Size: 14”x6”x12.5”       Available with rack mount kit     Other features: Real-time clock for time stamping       Store and Recall up to 999 Results       Speaker & Volume Control     Qualified: CE, RoHS en WEEE       Leveringsomvang:       l BJ08 Advanced Technology International Test Set l English manual l Computer/Internet Telephony Testing l Inter-Office Troubleshooting     l VoP, Voice Quality and Troubleshooting l Echo Canceller itesting and design verification l Installed equipment as part of a Test System l Qualification Testing at Customer Premises l OEM Testing in Manufacturing/Production l Laboratory Standard           Opties
