Key DSn/PDH and SONET/SDH Features
Simplified BER Testing
The FTB-880 NetBlazer provides the ability to preconfigure bit-error-rate (BER) thresholds that are user-defined prior to running the test. This allows for a simple pass/fail verdict at the conclusion of the test, leaving no room for misinterpretation of the test results.
The Decoupled mode enables the user to independently configure the Tx and Rx ports of the FTB-880 NetBlazer module. This makes it possible to test the mapping and demapping functionality of a network element or at cross-connect points in the network.
This mode is required for in-service monitoring of the network. The FTB-880 NetBlazer can be inserted in-line on a specific link to monitor and analyze the errors and alarms in a non-intrusive manner.
Simplified Error Injection
This FTB-880 feature enables the user to inject errors with a single click from any screen, allowing technicians to ensure circuit continuity prior to starting a test. Furthermore, the error injection functionality can be preprogrammed for any given type of error, and not just for bit errors.
Complete Overhead Monitoring
The FTB-880 NetBlazer offers access to the entire SONET/SDH or OTN overhead (OH) bytes. Furthermore, by selecting any given OH byte, the user can retrieve additional detailed information about that byte without having to switch pages.
Key ISDN Features
The FTB-880 lets you test and troubleshoot North American or European ISDN PRI configurations. It offers best-in-class PRI-ISDN
testing by allowing field technicians to call one or all 24 DS1 or 31 E1 PRI channels. Once connected, the user can go channel by channel to perform a BER test on individual or all channels as well as talk and listen via a headset.
Talk? Listen? Inject DTMF?
With one click, field technicians can talk and listen with simplicity—no need for a clumsy butt set. The FTB-1 platform allows the use of a handy, lightweight headset, which can be controlled via software to inject DTMF tones or speaker and microphone levels.
Who’s Calling? What Type of Calls?
As the calls come in or leave the ISDN primary rate interface, the summary results screen shows a crystal-clear analysis with its own unique call monitoring grid. With one glance, users see all call information: types of calls, stats such as idle, voice, 3.1 kHz, ringing, alerts, In Error, BER, pass or fail.
As with all NetBlazer modules, field technicians have complete control at their fingertips at all times, whether it’s a phone book, headset activation, DTMF injection, error injection, report generation, or save and load configurations. These utilities are always a finger’s touch away from activation.
Key Ethernet Features
Intelligent Network Discovery Mode
Using the FTB-880 or the FTB-860x test set, you can single-handedly scan the network and connect to any available EXFO datacom remote tester. Simply select the unit to be tested and choose whether you want traffic to be looped back via Smart Loopback or Dual Test Set for simultaneous bidirectional EtherSAM and RFC 2544 results. No more need for an additional technician at the far end to relay critical information—the NetBlazer products take care of it all.
Smart Loopback Flexibility
The Smart Loopback functionality has been enhanced to offer five distinct loopback modes. Whether you are looking to pinpoint loopback traffic from a UDP or TCP layer, or all the way down to a completely promiscuous mode (Transparent Loopback mode), the FTB-880 or the FTB-860x NetBlazer has the flexibility to adjust for all unique loopback situations.
Dual-Port and Through Mode Testing
The NetBlazer series is equipped for both Through mode or dual-port testing. Through mode allows traffic to pass through either of the NetBlazer's two electrical or optical ports for in-service troubleshooting of live traffic between the carrier/service provider network and the customer's network. This allows technicians to access circuits under test without the need for a splitter. With dual-port testing, the technician can use a single NetBlazer module to launch the test and perform the loopback. With two NetBlazer series modules, the dual-port feature also enables users to run two simultaneous tests to maximize time and efficiency.
Today's networks are expected to deliver high performance. To match such high expectations, service providers must rely on various mechanisms, such as Ethernet tagging, encapsulation and labeling. Thanks to these additions, service providers can enhance security, scalability, reliability and performance. The NetBlazer series supports virtual local area network (VLAN) tags, Q-in-Q VLAN tags and multiprotocol label switching (MPLS).
EtherSAM: The New Standard in Ethernet Testing
RFC 2544 used to be the most widely used Ethernet testing methodology. However, it was designed for network-device testing in the lab, not for service testing in the field. ITU-T Y.1564 is the new standard for turning up and troubleshooting Carrier Ethernet services. It has a number of advantages over RFC 2544, including validation of critical SLA criteria, such as packet jitter and QoS measurements. This methodology is also significantly faster, therefore saving time and resources while optimizing QoS.
EXFO’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.
Contrary to other methodologies, EtherSAM supports new multiservice offerings. It can simulate all types of services that will run on the network and simultaneously qualify all key SLA parameters for each of these services. Moreover, it validates the QoS mechanisms provisioned in the network to prioritize the different service types, resulting in better troubleshooting, more accurate validation and much faster deployment. EtherSAM is comprised of two phases, the service configuration test and the service performance test.
Service Configuration Test
The service configuration test consists of sequentially testing each service. It validates that the service is properly provisioned and that all specific KPIs or SLA parameters are met. A ramp test is performed to verify the committed information rate (CIR)
, excess information rate (EIR) and traffic policing.
Service Performance Test
Once the configuration of each individual service is validated, the service performance test simultaneously validates the quality of all the services over time.
EtherSAM Bidirectional Results
EXFO’s EtherSAM approach proves even more powerful as it executes the complete ITU-T Y.1564 test with bidirectional measurements. Key SLA parameters are measured independently in each test direction, thus providing 100% first-time-right service activation—the highest level of confidence in service testing.
The times are constantly changing and the telecommunications industry is rapidly evolving to keep pace. This is especially true when it comes to mobile network operators (MNOs) and the delivery of their services. Bandwidth-hogging applications like high-definition video, media-rich content and interactive mobile applications are being introduced at an ever-increasing rate. The wireless infrastructure has to be modernized to keep up with the continuous, high bandwidth growth and to minimize latency. To meet these expectations, MNOs are now switching their infrastructures from legacy "copper to antenna" to fiber-to-the-antenna (FTTA). With the introduction of FTTA, MNOs can offer better performance with lower base-station costs. One key component of evolving to FTTA requires the addition of either the common public radio interference (CPRI) or the open base station architecture initiative (OBSAI).
Incorporating either CPRI or OBSAI, the actual base stations can be located in much less challenging locations, where size, climate and availability of power are much more easily managed. In addition, wireless network providers can maximize the base-station output by having multiple antennas per offsite base station.
With the NetBlazer series of modules, field techs can perform FTTA tests (CPRI or OBSAI). Whether the need is for 2.5 or 3.1 Gbit/s, the NetBlazer modules can perform a BER test that validates the fiber from the remote base station all the way to the remote radio head.
Efficiently Assessing Performance of Fibre Channel Services
The NetBlazer Series modules provide comprehensive testing capabilities for Fibre Channel network deployments, supporting multiple Fibre Channel interfaces.
Since most storage area networks (SANs) cover large distances, and because Fibre Channel has stringent performance requirements, it is imperative to test at each phase of network deployment to ensure appropriate service levels. EXFO’s NetBlazer series modules provide full wire-speed traffic generation at the FC-2 layer, which allows BER testing for link integrity measurements. The NetBlazer series also supports latency, buffer-to-buffer credit measurements for optimization as well as login capabilities.
Transmission of frames in a network is not instantaneous, and is subject to multiple delays caused by the propagation delay in the fiber and by the processing time inside each piece of network equipment. Latency is the total accumulation of delays between two end points. Some applications, such as VoIP, video and storage area networks, are very sensitive to excess latency.
It is therefore critical for service providers to properly characterize network latency when offering Fibre Channel services. The NetBlazer series modules estimate buffer-to-buffer credit value requirements from the performed latency measurement.
Buffer-to-Buffer Credit Estimation
In order to regulate traffic flow and congestion, Fibre Channel ports use “buffers” to temporarily store frames. The number of frames a port can store is referred to as a “buffer credit”. Each time a frame is received by a port, an acknowledgement frame is sent. The buffer-to-buffer credit threshold refers to the amount of frames a port can transmit without receiving a single acknowledgement.
This is a crucial configuration parameter for optimal network performance. Usually, network administrators calculate the value by taking the traveled distance and the data rate into consideration; however, since latency issues are not considered, poor accuracy is to be expected. The NetBlazer series modules are capable of estimating buffer credit values with respect to latency by calculating the distance according to the round-trip latency time. This value can then be used by network administrators to optimize the network configuration.
Most new-generation transport devices (xWDM or SONET/SDH mux) supporting Fibre Channel are no longer fully transparent; they also have increased built-in intelligence, acting more as Fibre Channel switches. With switch fabric login ability, the NetBlazer series modules support connections to a remote location through a fabric or semitransparent network.
The login process not only permits the unit to connect through a fabric, but it also exchanges some of the basic port characteristics (such as buffer-to-buffer credit and class of service) in order to efficiently transport the traffic through the network.
The login feature allows automatic detection of port/fabric login, login status (successful login, in progress, failure and logout) and response to remote buffer-to-buffer advertised credit.
EXFO Connect pushes and stores test equipment and test data content automatically in the cloud, allowing you to streamline test operation from build-out to maintenance.
