TTC 2230

• Auto-configuration - synchronise to the E1 framing format while determining channel activity on all timeslots.
• Datacom interface - perform BERT at a V.36, X.21, V.24, EIA-530, or V.35 interface. 'Mux wrap' supports simultaneous testing from E1 and datacom interfaces to check multiplexers and NTUs.
• Drop & Insert - perform tests on selected timeslots without affecting live traffic on remaining channels.
• Dual monitor - two balanced/unbalanced receivers enable complete monitoring of an E1 circuit. Check code errors, frame errors, and timing slips to verify circuit performance. Look for channel activity or drop a channel to the speaker to verify speech quality.
• Pre-programmed and manual dial sequences - the CAS and PRI options support emulation of customer premises equipment such as a PABX by placing calls across the network.
• Channel utilisation - comprehensive call statistics and call trace information, part of the CAS and PRI options, quickly isolate service problems. Full call statistics such as 'number of connected calls' and 'average call duration time' give a complete view of service quality.
• Event log - user-selected error conditions are recorded to the log along with timestamp and error description facilitating monitoring of circuit and service performance.
• Scan mode - use the CAS or PRI option to automatically scan all 30 channels for call activity and lock onto the first detected call to analyse signalling information.
