or automatically, remotely or locally, facilitating a loop-back test. Either your network is f*cked up or you use techniques like Spanning Tree to explicitely prevent your signal to be ever routed back to you.Īs you can see, the internal data routing is essential. Loopback (also written loop-back) is the routing of electronic signals or digital data. broadcast packages) lead to serious trouble in the network.Ĭase #3: You have a complicated network setup where loops are possible. It does not make sense to do it and would in some cases (e.g.

Two options to plug into your PC port - DB25 male and DB9.

The switch will in its routing automatically never send the signal back to the source. These slimline loopback testers can help diagnose problems with serial or parallel interfaces. The NIC has no interest in reading its own signal while sending it.Ĭase #2: The NIC sends the data to a switch. Nobody will talk back to the NIC about the signal. However I doubt you will ever be able to test the PHY without a second receiver.Ĭase #1: The NIC sends the data to a hub (do these still exist?).

Additionally, functions such as service disruption time (SDT), round trip delay (RTD) and OTN overhead analysis are readily available making the MAX-800 Series the most versatile portable tester in the industry.As you may have guessed, this is not a bug but a feature (and an essential one). Engineers and technicians can evaluate SLAs based on bit error rate (BER). This solution offers test functions that range from bit-error-rate (BER) measurements, service disruption time (SDT) to advanced characterization.ĮXFO has an extensive suite of features for testing optical transport network (OTN) deployments and many of them are also available on the MAX-800 Series.

With the large, installed base of legacy DSn/PDH and SONET/SDH circuits in access and metro Ethernet networks, testing, troubleshooting and maintenance have become daily tasks.Ĭovering all DSn/PDH and SONET/SDH interfaces, our ultra-portable MAX-800 handheld tester for DSn/PDH and full legacy SONET/SDH is ideally suited to field service deployment, in addition to installation, commissioning and maintenance of access and metro Ethernet networks. The Networx RJ45 Loop back tester will negate the necessity to carry a bulky network hub around. 50 cm Ethernet cable to connect to wall outlets.

USB cable for charging and firmware updates. DSn/PDH, SONET/SDH and OTN testingĮXFO is a recognized leader in network testers and telecom solutions. 1 Remote terminator (for Wiremap and BER tests) Protective carrying pouch. EtherSAM is comprised of two phases, the service configuration test and the service performance test. This suite also enables complete validation of all SLA parameters within a single test to ensure optimized quality of service. Aligned with the requirements of today's Ethernet services, the EtherSAM test methodology drastically speeds up deployment and eliminates repeat testing by offering full visibility into all service-level agreement (SLA) metrics, immediately and accurately. Transport network testing up to 100G including optical SONET/SDH and OTNĮtherSAM: the standard in Ethernet testingĮXFO's EtherSAM test suite-based on the ITU-T Y.1564 Ethernet service activation methodology-provides comprehensive field testing for mobile backhaul and commercial services.

Optional 4 x 100GE EtherBERT Layer 2 testing.Independent dual-port testing up to 100GE.Transport network testing up to 100G: optical SONET/SDH and OTN.If the jack isnt working it will display a self-assigned IP. If the interface fails to receive any test packet, the hardware of the interface is faulty. During the external loopback testing, the port sends out a certain number of test packets, which are looped over the plug and back to the interface. The computer will display an IP address and a subnet if the jack is working, such as 192.162.0.1 / 255.255.255.0. To perform external loopback testing on an Ethernet interface, insert a loopback plug into the port. Bring up the Network control panel on a Macintosh or the Local Area Connection network control panel on a PC. Transport network testing up to 10G: DSn/PDH, ISDN, SONET/SDH and optical transport network (OTN) PMA loopback (PCS loopback does not work) and then enable PRBS for all lanes on the Xena tester, and let the test run for at least 24 hours before verifying that there are no PRBS errors detected. Plug your laptop into the wall jack using an ethernet cable.

Optional IPv6, MPLS, Through mode and dual-port testing.

Ethernet testing including RFC 2544, EtherSAM ITU-T Y.1564, EtherBERT, traffic generation and monitoring (multistream) and Smart Loopback.
