The T6300A is a handheld all-in-one PRI and network testing instrument, integrating Ethernet, E1/PRI, V.35/V.24, OTDR, and optical power meter functions in a single device. It simplifies testing, troubleshooting, and maintenance of both traditional telecom and modern IP/fiber networks.
Product Features:
📌 All-in-One Multi-Interface Testing
Combines Ethernet (10/100/1000M), E1/PRI, V.35/V.24, OTDR, and optical power meter into a single handheld device. Eliminates the need to carry multiple testers, improving efficiency and reducing costs.
📌 RFC2544 Network Performance Testing
Supports throughput, latency, jitter, frame loss, and back-to-back testing up to Gigabit speeds. Dual-port and loopback modes allow accurate end-to-end performance validation, essential for SLA verification.
📌 PRI & E1 Testing with 30B+D Signaling
Provides real-time verification of ISDN PRI signaling, call simulation, monitoring, and analysis of voice and data channels. Ensures quick diagnosis of line faults in PBX and carrier networks.
📌 Integrated Fiber Testing
Built-in OTDR (1550nm) and optical power meter (800–1700nm) allow fiber fault location, loss measurement, and connector inspection without additional devices. Ideal for FTTx and optical network maintenance.
📌 Dual Ethernet & Optical Ports with Auto-Detection
Independent dual 10/100/1000M copper ports and dual SFP optical ports automatically detect network speed and duplex mode. Supports testing of both copper and fiber connections for LAN and carrier networks.
📌 Long Battery Life & Data Storage
6000mAh battery provides up to 6 hours of continuous operation. Stores up to 1000 test results with USB/TF card export options for easy reporting and documentation.
