Synchronous ethernet test option for CMA 3000 field tester
1 min read
Anritsu's new option supports synchronous ethernet testing from 10 to 10Mb/s. Test of the two techniques that defined for Ethernet synchronisation are supported:
* Physical synchronisation signal forwarding as defined in ITU-T recommendations G.8261, G.8262 and G.8264 (in many cases this is now called SyncE)
* Protocol based synchronisation as defined in IEEE1588 v2 Precision Time Protocol (PTP)
The new option allows both active out of service testing and in service bi directional monitoring of synchronous ethernet links for analysis of live networks. According to Anritsu, the CMA 3000 field tester has supported dual port testing at 10Gb/s for more than a year and also supports dual port testing of synchronous ethernet links at 10Gb/s.
According to Anritsu, the new option is designed to enable operators and equipment manufacturers to quickly test and measure network communication links based on synchronous ethernet. Further options support testing of ethernet up to 10Gb/s, IP, VoIP, SDH up to STM-64, E3, E4 and V-series interface lines, along with E1 test capabilities for the basic CMA 3000.
The bidirectional monitoring capability enables users to verify that both sides of the synchronous ethernet link are working properly with the new option for the CMA 3000. For out of service installation and commissioning testing of synchronous ethernet links, the CMA 3000 provides statistical measurements that can be documented with professional reports.
For IEEE 1588 v2 (PTP) the instrument can also:
* Act as a master using the internal instrument clock or a GPS signal (when present) as clock source.
* Act in slave mode; this involves choosing the best master wall clock and constantly adjusting the clock.
Hereby the user can make the CMA 3000 simulate an IEEE 1588 v2 (PTP) clock and verify that the PTP network works correctly.
"We see that synchronous ethernet is coming into today's communication networks in particular in mobile networks, where there is a need to migrate from legacy synchronous technologies (SDH and PDH) to Ethernet," said Ole Soerensen, product manager, Anritsu A/S. "Although these operators are moving to Ethernet and IP based networks, they still have the legacy technologies in their networks and need to keep them operational. Therefore, it is important for field technicians installing and maintaining access networks to have a universal tool like the CMA 3000 to test all the technologies they have to take care of."
