General DescriptionThe Ethernet DSL remote unit (ATU-R) (A90-36R210W00) terminates a DSL line at thesubscriber location. The 10BaseT Ethernet DSL system uses Carrierless Amplitude PhaseModulation (CAP) transmission to provide reliable DSL transport over the existing coppercable infrastructure. The ATU-R separates CAP high-speed downstream and lower-speedupstream channel data and POTS (Plain Old Telephone Service) signals which have beentransported via twisted-pair copper wires between an access line module at the central officeand the subscriber premises. The ATU-R provides an industry standard 10BaseT interfaceto the customer’s CPE equipment. Application software is fully downloadable to allow forfuture enhancements. The ATU-R is available with or without an optional internal POTSsplitter.ATU-R Options CLEI FCC ID NumberA90-36R210 Without Internal POTS Splitter VARTFMD1AA CH8AR2102.

InspectionUpon receipt, thoroughly inspect the remote unit for damage. If the remote unit has beendamaged during transit, please report the damage immediately to the transportationcompany and to your Westell representative. Responsibility for safe delivery of goods isassured by the transportation carrier. Refer to the SuperVision Service/Technical SupportSection of this manual for further information.6. Product OverviewThe remote unit is located at the subscriber’s premises and terminates the digital subscriberline originating from the (ATU-C) in the central office.The software within the ATU-R completely controls the hardware by providing an embeddedsystem that implements a multiport learning MAC layer bridge that interfaces betweenLogical Link Control/Subnetwork Access Protocol (LLC/SNAP) AAL5 encapsulated ATM cell-based, bridged protocol data units (PDUs) and 10BaseT Ethernet frames. The AAL5 layer isthe layer that supports connection-oriented, variable-bit-rate data services such as thetypical "bursty" data traffic found in today's LANs. The LLC sublayer handles error control,flow control, framing, and MAC-sublayer addressing.6.1 Features and FunctionsThe ATU-R provides a flexible platform for providing DSL services and applications. Thesefeatures include:• No in-home configuration required. Once the ADSL line is provisioned by the telco,the ATU-R is plug-and-play.

The POTS signal is carried in thevoice band frequency range, 0 to 4 kHz, that is specified by the telephone network voiceswitch. The ADSL video and data signals are carried in the frequency range above 35 kHz(out-of-voice band). The upstream channel occupies the frequency range between 35 kHzand 170 kHz. The downstream channel occupies the range above 240 kHz and below 1.551MHz.ATU-R to Subscriber – The ATU-R receives the modulated signal from the access linemodule and then separates the POTS signal from the DSL signal. The POTS signal isrouted to the subscriber’s telephone. The ATU-R demodulates the DSL signal and routes itto the PC or other user equipment via an 10BaseT interface.6.7 10BaseT Ethernet DSL DiagnosticsThe system includes built-in diagnostics that may be invoked through the element-management system. Diagnostics are performed at the card level on an individual basis andresults are sent back to the EMS system.The Ethernet DSL system provides the unit self-test diagnostic to facilitate trouble isolationand restoral. Unit self-tests verify the operation of the units themselves and are used todetermine whether the equipment is causing specific problems. When card-leveldiagnostics are performed, the cards and circuits under test are taken out-of-service.
SuperVision® System ManualCAP Rate-Adaptive Ethernet DSL Remote UnitA90-36R210W00Part # 030-1010xxA90Rev. P2, 07/01/981998, Westell, Inc.Release 1.2 Printed in the USA10BT-R.DOC10Test results are displayed as each diagnostic routine completes. Diagnostic self-tests areperformed upon start-up, and then only when requested by the element-managementsystem. This diagnostic causes the DSL loop to go through a retraining sequence and isconsidered to be intrusive diagnostics.6.8 System Status and Performance ManagementThe CAP DSL system utilizes a Reed Solomon forward error correction (FEC) algorithm anda convoluted interlever to improve performance on noisy transmission lines.The ATU-R can verify connectivity to the central office line and via loopbacks of F5 OAMcells. Upon receiving this cell through the ADSL interface, the ATU-R will loop back this cellto the originator via the ADSL network interface.On normal power-down, the ATU-R will generate a “dying gasp” message to the ATU-C toindicate a power-down status.A visual indicator on the front panel READY LED provides an indication of severely erroredcondition occurring on the DSL link. This errored card threshold is programmed into thesystem via the element management system. Once the threshold has been crossed, theREADY LED will blink intermittent red.A variety of statistics are maintained by the common control modules on performance of thedigital subscriber line (DSL). The ATU-R reads its performance monitoring data and thenforwards the data to the central office module for reporting via the element-managementsystem. The data that is collected includes:• CODING VIOLATION (CV) – A CRC error over the DSL link. Note that there aredownstream coding violations and upstream. CV violations are use by the ATU-Cs tocalculate Errored Seconds (ES), Severely Errored Seconds (SES), and UnavailableSeconds (UAS). • DSL HEC (CELL HEADER ERROR CORRECTION BYTE) ERROR SECONDS (DHES) – A countof one-second periods where at least one HEC Error was observed. • SIGNAL-TO-NOISE MARGIN (SNM) – The current signal margin recorded. • LINE ATTENUATION (ATTN) – The current line attenuation recorded.7.
