ANT-5 SDH Access Tester (Discontinued)

Installation and commissioning solution for SDH, SONET, PDH, and ATM access networks with line rate testing from 1.544 Mb/s to 2.5 Gb/s.


  • Configurable and upgradeable with a wide range of optical interfaces and SW options, e.g. ATM.
  • All interfaces built in: Electrical interfaces for PDH/SDH: T1,E1,E3,DS3,E4, STM-0e/1e; Optical interfaces (option) for SDH/SONET: Single and Dual optics Tx up to 2.5 G, covering: STM-1/OC-3, STM-4/OC-12, and STM-16/OC-48.
  • Autoconfig functionality for automatic traffic detection (line rate, structure, mapping).
  • PDH Mux/Demux testing down to 64 kbps (E1/E3/E4 and DS1/DS3 Mux/Demux chain).
  • ATM test functionality with all supported bit rates and mappings up to Vc4-4c.
  • Offline Viewer SW provides impressive result analysis and report generation on any Microsoft Windows-based printer. Generation of instrument configuration for transfer to the unit itself.
  • Built-in Ethernet port for extended connectivity, enabling remote operation and results transfer.


  • Installation and commissioning of STM-0e/1/4/16, OC-3/12/48, and E4, DS3, E3, E1, and T1 links.
  • Troubleshooting features for easier fault location.
  • In-service and out-of-service testing with in-line monitor and intrusive thru mode functionality. Enables interruption free service monitoring via ECL NRZ Rx ports (STM-n).
  • ATM service verification: Testing of ATM carried over PDH, SDH, and SONET.
  • 3G/UMTS network installation and commissioning with Channel Explorer functionality detecting active VCI/VPIs.
  • Radio link adjustments by repetitive BERT functionality.
