DSL service providers are under extreme pressure to ensure that this massiveinfrastructure continually provides the level of service expected by customers. And thisrequires the use of testing equipment that performs multiple tests and procedures,validates and confirms proper operation of the network and its various components, andtroubleshoots problems on the spot—all at a price that fits a tight budget. The ActernaDSL Services Tester TPI 350 is designed to satisfy these criteria as well as meet the testingrequirements of highly mobile technicians who commission, troubleshoot, and maintainDSL service throughout the network.

Rugged, lightweight, and compact, the DSL Services Tester is easy for tier one, tier two, and tier three service technicians tolearn and use. It is a powerful test set capable of testing and validating customer connections from the lower transmissionlayer network protocols all the way up through the customer applications, including ISP/Internet connectivity. And withpoint-to-point protocol, technicians can look past the DSLAM into any network and verify correct mapping and connectivity.Combined with the SLK, the DSL Services Tester provides a complete solution for DSL service commissioning on the localloop. For further network testing, the DSL Services Tester can be coupled with the Acterna TestPad 2000 SONET FieldServices Module or the Acterna ATM Tester 750A to validate DSLAM mappings.Function Highlights Validates DSL physical layer performance and troubleshoots slow DSL.Provides point-to-point protocol support for PPPoA, PPPoE, DHCP/IPCP, CHAP, PAP, and LCP.Analyzes Bridged Ethernet, PPPoA, PPPoE, and IP over ATM data layers with PING and Through mode.Supports TE mode and ATM Loopback mode.Isolates the ATM layer as a source of problems, validates log-in functions and authentication protocols, and verifies theprovisioning of the customer’s ISP account and Internet connection.Tests customer applications and isolates customer premises equipment (CPE) problems using built-in Through modeand Ethernet terminal equipment functionality via the Ethernet port.Troubleshoots local loop faults impacting DSL service by segmenting faults at any point along the loop.Generates numerous link control error messages and statistics for actual and maximum upstream and downstreamconnect rates, percentage of line capacity used, noise margins, and transmission power.Allows PING changes to be made without rebooting.ApplicationsTechnicians need to test all the connections of a DSL network—from the CPE, through the network, to the ISP—before theprovider can commission DSL service. Since failure of any transport, network, or service layer function (protocol) may causethe service to fail, technicians need to check more than synchronization between the network interface device (NID) andDSLAM. With the DSL Services Tester, technicians can test the customer’s entire service, not just DSL sync, which eliminatesrepeat trucks rolls to troubleshoot the network connection and CPE.Check ATM Layer Synchronization at the CPECustomerPremisesATMSwitch.comInternetAccess RouterISPDSL Modem"NO ATM SYNC"UnbundledCopper LoopsDSLAMATM CellsThe “NO ATM SYNC” warning indicates an incorrectly provisioned circuit, a DSLAM mapping error, or a misconfigured ATM switch.Before a provider commissions and provisions DSL service in an ATM network, and to maintain the service at the highestlevel of performance, technicians perform tests to validate and confirm several protocol layers.2

ATM cells must be synchronized from end-to-end for the network to reliably transport data and voice signal payloads.However, when ATM synchronization is absent at the premises users cannot establish a connection.Technicians use the DSL Services Tester to determine if a complete path or circuit exists from end-to-end at the ATM layerand if the ATM cells are aligned with the upper layer protocols (i.e. IP). With the DSL Services Tester, the source of theproblem can be found and corrected immediately so that users are back online without delay.The DSL Services Tester employs real-signal technology on the loop. This capability is important because network customersoften connect to the ISP using point-to-point protocol, which is usually a client on the customer’s PC or modem. Thisprotocol establishes and maintains the customer’s connection through the network by establishing a permanent circuit orroute at network layers 2 and 3. With the DSL Services Tester, technicians can test the network server’s performance from thecustomer site.Verify IP Layer Routing and ConnectionsPoint-to-PointProtocolLog-in: Username/PasswordCustomerPremisesDSL mISPLog-in: Username/PasswordDSL Services TesterThe DSL Services Tester ensures a successful point-to-point protocol connection from the customer to the ISP.With the universal deployment of IP, especially for the Internet, it is critical that the network transports data correctly toensure that common Internet applications such as Web browsers, e-mail, and streaming video function properly. The DSLServices Tester, using the common PING utility associated with most IP stacks or suites, verifies routing connectivity acrossthe network to an IP host or server, and it also assesses packet loss rates and packet delay to and from the PING destination.To test the IP layer, the DSL Services Tester checks if another host device is alive and able to echo back; uses Flood mode togauge network congestion; and determines the minimum, maximum, and average delay time of IP packets. By trackingpacket delay and loss on various network segments, the DSL Services Tester’s PING utility helps providers prove to theircustomers that delays and slow service are not due to provider error.DSL Services TesterPING.comIP PING TX/RX Time % LostISPPINGATMCloudThe DSL Services Tester verifies IP layer routing.3

Verify Applications and Isolate CPE ProblemsDSL Services TesterNIDCustomerPremisesWANDSLAMDSL ModemResults can be easily viewed from a laptop or the DSL Services Tester.While network customers may transport basic user data over IP, they typically use specific applications to interact withInternet Web sites, news services, and e-commerce databases as well as to collaborate via video and office applications. Todemonstrate and validate that a customer’s applications are functioning properly, technicians connect the DSL Services Testerto the customer’s PC or laptop, activate the DSL Services Tester’s built-in Through mode, and run the applications.Technicians can also completely isolate CPE components by replacing the customer’s modem with the DSL Services Tester.Validate DSLAM MappingsDSL Services TesterWANATMNOCDSLAMThe DSL Services Tester can help validate and troubleshoot port mappings.Technicians ensure a customer’s high-speed DSL connection by conducting tests to confirm that the DSLAM is correctlyprovisioned for each connection and port at the DSL/ATM layer interface (mapping). Although the network operationscenter (NOC) can often configure and monitor ATM traffic down to the DSLAM, incorrect mappings in the DSLAM willprevent the customer from connecting to the network. Placing the DSL Services Tester in ATM Loopback mode allowstechnicians to validate or troubleshoot these port mappings. To confirm the mappings, technicians can either activate theDSL Services Tester’s Loopback All mode while the DSLAM is in service or operate it in conjunction with other Acternatest equipment, such as the SONET Field Services Module or the ATM Tester 750A, while the DSLAM is out-of-service.Also, when the DSL Services Tester is used along with other Acterna test products, such as the SONET Field Services Moduleor the ATM Tester 750A, it can identify and increment Acterna-type test cells. By placing the DSL Services Tester inLoopback mode, technicians can provide absolute confirmation that an ATM cell traveled the correct path and reachedthe correct destination.DSL Services TesterDSL Services TesterOEM Test CellOEM Test Cell 1DSLAMWith Acterna TestPad 2000 application modules, the DSL Services Tester can confirm passage of ATM cells.4

Verify Service RatesDSL Services TesterOffice (LEC)CustomerPremisesNIDDSL ModemMain DistributorFrameDSLAMThe DSL Services Tester 350 emulates DSL transceiver-unit modems to confirm DSL physical layer performance.Although DSL provides a high-speed link between the provider’s high-speed network and the CPE and can support highspeed digital services such as DSL, dial-up modem service is the typical bottleneck on the local loop. The DSL Services Testerlets technicians quickly and easily confirm DSL physical layer performance by emulating DSL transceiver unit modems. Inthis mode, the DSL Services Tester verifies the actual DSL rate for the current connection and the connection’s maximumpossible rate. It checks the signal-to-noise margin to evaluate the DSL signal strength over the loop, pointing to futureperformance capabilities or limitations. Technicians can synchronize the DSL Services Tester at different points on the loopto segment faults on the copper loop.The DSL Services Tester’s data rate and line rate results verify slow service. By looking at the "bits per tone" measurementand graphics, technicians can determine if the disturbers are from sources transmitting T1, E1, or HDSL and take correctiveaction. In addition, the DSL Services Tester indicates excessive noise margins, which identify the presence of crosstalk.Generic Operational ParameterDefinitionUnit RangeResolutionSNR marginAmount of increasednoise relative to noisepower that system cantolerate, still meetingBER of 10-70 to 63 db1 db8,160 kbps8,160 kbps8,160 kbps8,160 kbps0 to 100 %0 to 64 db128 bytes128 bytes0 to 150 to 255 db32 kbps32 kbps32 kbps32 kbps11 db1 byte1 byte11 dbMaximum line rate downstreamActual line rate downstreamMaximum line rate upstreamActual line rate upstreamLine capacityAttenuationUpstream interleaved depthDownstream interleaved depthBits per toneSNR per toneSignal loss with distanceNumber of bits per toneSignal-to-noise ratio per toneThe DSL Services Tester’s “bits per tone” graphics and measurements identify sources of disturbance.5
