P2, 07/01/98 CAP RATE-ADAPTIVE ETHERNET DSL REMOTE UNIT WITH FLASH (ATU-R) 1. General Description The Ethernet DSL remote unit (ATU-R) (A90-36R210W00) terminates a DSL line at the subscriber location. The 10BaseT Ethernet DSL system uses Carrierless Amplitude Phase Modulation (CAP) transmission to provide reliable DSL transport over the existing copper cable infrastructure. The ATU-R separates CAP high-speed downstream and lower-speed upstream channel data and POTS (Plain Old Telephone Service) signals which have been transported via twisted-pair copper wires between an access line module at the central office and the subscriber premises. The ATU-R provides an industry standard 10BaseT interface to the customer’s CPE equipment. Application software is fully downloadable to allow for future enhancements. The ATU-R is available with or without an optional internal POTS splitter. ATU-R Options A90-36R210 2.

Product Overview The remote unit is located at the subscriber’s premises and terminates the digital subscriber line originating from the (ATU-C) in the central office. The software within the ATU-R completely controls the hardware by providing an embedded system that implements a multiport learning MAC layer bridge that interfaces between Logical Link Control/Subnetwork Access Protocol (LLC/SNAP) AAL5 encapsulated ATM cellbased, bridged protocol data units (PDUs) and 10BaseT Ethernet frames. The AAL5 layer is the layer that supports connection-oriented, variable-bit-rate data services such as the typical "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 Functions The ATU-R provides a flexible platform for providing DSL services and applications. These features include: • No in-home configuration required. Once the ADSL line is provisioned by the telco, the ATU-R is plug-and-play. 1998, Westell, Inc.

Defaults to zero (range 0 - 8). • VIRTUAL PATH IDENTIFIER (VPI) NUMBER – An 8-bit field in the ATM cell header that indicates the virtual path over which a cell is to be routed. It is the VPI address of the PVC. Defaults to zero (range 0-255). • VIRTUAL CHANNEL IDENTIFIER (VCI) NUMBER – The unique numerical tag used to identify every virtual channel across an ATM network, defined by a 16-bit field in the ATM cell header. It is used for the addressing information carried on ATM cells. Indicates the VCI address of the PVC. Defaults to zero (range 0 - 65,535). • PEAK CELL RATE (PCR) – A traffic management parameter that determines how often data samples are sent. Defaults to 3600 cells per second (range 0-30,000). • CELL DELAY VARIANCE TOLERANCE (CDVT) – A network descriptor parameter that characterizes the delay jitter/cell clumping that can be encountered by cells in the network and CPE devices. It is used in conjunction with PCR and SCR. Defaults to zero (range 0 - 255). Measured in cell times. 1998, Westell, Inc. Release 1.2 Printed in the USA 10BT-R.DOC SuperVision® System Manual CAP Rate-Adaptive Ethernet DSL Remote Unit A90-36R210W00 Part # 030-1010xx A90 Rev. P2, 07/01/98 • SUSTAINABLE CELL RATE (SCR) – Determines the long-term average cell rate that can be transmitted. Default is 3600 cells per second (range 0 - 30,000). • M AXIMUM BURST SIZE (MBS) – Defines the maximum cell burst size at the peak cell rate (PCR). Default is zero (range 0 - 255). Measured in cells at the PCR. • BRIDGE M ODE – Static or Learned. Default is learned. • UPSTREAM CELL RATE (UCR) – Defines the upstream cell rate in cells per second. Allows for control of upstream data at the ATM layer as opposed to the DSL line rate when set to 0. Upstream cell rate equals DSL line rate. Default is 0, (range 0 30,000). • BRIDGE AGING INTERVAL – Determines the length of time a MAC-to-ATM PVC binding is stored in bridge before a refresh is needed. Default is 1800 seconds (range 0 65,535 seconds). • MAC ADDRESS – A 48-bit MAC address. Up to 16 addresses can be provisioned to use with static bridge mode operation. • UPSTREAM TRANSMIT POWER – Upstream transmit power can be programmed from 0 dB to -12 dB in 3-dB increments from typical transmit power of -13.3 dB. This means maximum upstream transmit power can be set in the range of -13.3 dB (0 dB ∆) to 25.3 dB (-12 dB ∆). PER PVC PARAMETERS ENABLE/DISABLE FORWARDING OF ALL ETHERNET BROADCAST FRAMES – An Ethernet Broadcast frame is a data packet that will be sent to all nodes on a network. Broadcasts are identified by a broadcast address. Generally, the broadcast address is a destination address of all ones. Default is Disabled (only forward IP broadcasts). ENABLE/DISABLE FORWARDING OF ALL ETHERNET M ULTICAST FRAMES – A multicast frame is a data packet copied by the network and sent to a specific subset of network addresses. These addresses are specified in the destination address field. Single addresses that refers to multiple network devices. Synonymous with group address. Default is Disabled (on multicasts forwarded). ENABLE/DISABLE ETHERNET FRAME CHECK SEQUENCE (FCS) PRESERVATION – Frame check sequence refers to the extra characters added to a frame for error-control purposes. It is used in most data link-layer protocols. The Ethernet FCS consists of four extra characters at the end of the frame. Default is Disabled (FCS not preserved). 1998, Westell, Inc.

Pinout for 10BaseT interface 6.6 Rx+ RxTx+ Not Used Not Used TxNot Used Not Used Signals ATU-C to ATU-R – POTS and DSL signals are sent from the access line module at the central office to the ATU-R over the digital subscriber line. The POTS signal is carried in the voice band frequency range, 0 to 4 kHz, that is specified by the telephone network voice switch. 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 kHz and 170 kHz. The downstream channel occupies the range above 240 kHz and below 1.551 MHz. ATU-R to Subscriber – The ATU-R receives the modulated signal from the access line module and then separates the POTS signal from the DSL signal. The POTS signal is routed to the subscriber’s telephone. The ATU-R demodulates the DSL signal and routes it to the PC or other user equipment via an 10BaseT interface. 6.7 10BaseT Ethernet DSL Diagnostics The system includes built-in diagnostics that may be invoked through the elementmanagement system. Diagnostics are performed at the card level on an individual basis and results are sent back to the EMS system. The Ethernet DSL system provides the unit self-test diagnostic to facilitate trouble isolation and restoral. Unit self-tests verify the operation of the units themselves and are used to determine whether the equipment is causing specific problems. When card-level diagnostics are performed, the cards and circuits under test are taken out-of-service. 1998, Westell, Inc. Release 1.2 Printed in the USA 10BT-R.DOC SuperVision® System Manual CAP Rate-Adaptive Ethernet DSL Remote Unit A90-36R210W00 Part # 030-1010xx A90 Rev. P2, 07/01/98 Test results are displayed as each diagnostic routine completes. Diagnostic self-tests are performed upon start-up, and then only when requested by the element-management system. This diagnostic causes the DSL loop to go through a retraining sequence and is considered to be intrusive diagnostics. 6.8 System Status and Performance Management The CAP DSL system utilizes a Reed Solomon forward error correction (FEC) algorithm and a 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 OAM cells. Upon receiving this cell through the ADSL interface, the ATU-R will loop back this cell to the originator via the ADSL network interface. On normal power-down, the ATU-R will generate a “dying gasp” message to the ATU-C to indicate a power-down status. A visual indicator on the front panel READY LED provides an indication of severely errored condition occurring on the DSL link. This errored card threshold is programmed into the system via the element management system. Once the threshold has been crossed, the READY LED will blink intermittent red. A variety of statistics are maintained by the common control modules on performance of the digital subscriber line (DSL). The ATU-R reads its performance monitoring data and then forwards the data to the central office module for reporting via the element-management system. The data that is collected includes: 7. • CODING VIOLATION (CV) – A CRC error over the DSL link. Note that there are downstream coding violations and upstream. CV violations are use by the ATU-Cs to calculate Errored Seconds (ES), Severely Errored Seconds (SES), and Unavailable Seconds (UAS). • DSL HEC (CELL HEADER ERROR CORRECTION BYTE) ERROR SECONDS (DHES) – A count of one-second periods where at least one HEC Error was observed. • SIGNAL-TO-NOISE M ARGIN (SNM) – The current signal margin recorded. • LINE ATTENUATION (ATTN) – The current line attenuation recorded.
