• Validates network scalability with VLAN, Q-in-Q, MAC-in-MAC Ethernet-over-Ethernet, MPLS, and VPLS tunnelling technologies.
• Support for ODU multiplexing including ODU1, ODU0, and ODUflex
• Test emerging 5G technology with eCPRI specific testing including One-Way-Delay (OWD)
• Full-featured VoIP and IP video turn-up and troubleshooting tests
• Supports packet transport network (PTN) evolution with MPLS-TP technology
• Ethernet Service Disruption with multi-tier triggers
• Run Bi-Directional Forwarding Detection (BFD) against switch and router partners while generating traffic to measure KPIs

Empower Cell-Site Technicians – Fiber testing to CPRI and eCPRI

Copper kit

T-BERD/MTS-5800 tools let cell-site technicians efficiently install and maintain backhaul and fronthaul networks. They can ensure BBU and RRH connectivity with CPRI and OBSAI tests:

• Validate C-RAN connectivity across CWDM networks
• Test RRH health from the bottom of the tower or from a C-RAN location by emulating a BBU
• Identity PIM and interference issues from an optical test access point including quad spectrum with enhanced markers.(RFoCPRI)
• Support 2-Tone PIM generation enabling PIM detection without climbing a tower
• Bit Error Rate Test eCPRI fronthaul circuits
• Validate RJ-45 Ethernet wiring is properly crimped down and wire mapped including end-to-end shield ground connectivity
• CPRI Check automates setting Antenna Tilt, detecting PIM and reading VSWR

And, they can verify network synchronization:

• Emulate a 1588v2 master clock/slave recovery for proper point-to-point (PTP) message propagation and packet-delay variation (PDV) verification
• Verify SyncE frequency synchronization accuracy and Ethernet synchronization message channel (ESMC) message propagation
• Measure wander on SyncE, 1PPS, T1, E1, and 2 and 10 MHz signals
• Track satellite movements to optimize GPS antenna placement
• Test Floor Packet Percentile per ITU PTP Frequency recommendations

When equipped with an OTDR module, the T-BERD/MTS-5800 is the perfect solution for mobile network testing, providing easy fiber link characterization and troubleshooting.
