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
subscrib er location. The 10BaseT Ethernet DSL system uses Carrierless Amp litud e 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 twis ted - pair c opper wires bet ween an acces s line m odul e at t he centr al 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.

Wh en ever th is sect ion of t he m anu al is revised , t h e reason wil l b e st ated in t h is su bs ection .
Each time a revision is made, the revision level (located in the upper right corner) will be
inc reased b y one l etter. In add ition , any c hang es in f it, form or fu nct ion of t he equip ment
will cause the issue letter (located in the upper right corner) to be increased. An explanation

3. Build Control
The remote unit (ATU-R) is identified by an issue letter and model number imprinted on the
bottom of the unit. Each time a change is made to the product which changes the form, fit
or fu nction of the prod uct, the issue letter is advanced. Be sure to indicate the unit’s issue
letter and model number when making inquiries about the product. The release number in
the bottom left corner indicates the release(s) for which the module or section is valid.

Refer to the System Overview (030-100983) section, Parag raph 5, for a comp lete list of all
system element compatibil ity.
5. Inspection
Upon receipt, thoroughly inspect the remote unit for damage. If the remote unit has been
damaged during transit, please report the damage immediately to the transportation
company and to your Westell representative. Responsibility for safe delivery of goods is
assured by the transportation carrier. Refer to the
Section of this manual for further information.

6. Product Overview
The remote unit is located at the subscriber’s premises and terminates the digital subscriber
line originatin g 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 cellbas ed, bridged protocol d ata u nit s ( P DUs ) and 10BaseT Eth er net frames . Th e AAL5 l ay er 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 f lexibl e pl atform f or provid ing DS L services and app lication s. Th ese
feat ures includ e:
•
No in-home configuration required. Once the ADSL line is provisioned by the telco,
the ATU-R is plug-and-play.

6.2 Transmission
The system uses Carrierless Amplitud e Phase Mod ulation (CAP) technology t o deliver from
640 kbps to 7.1 Mbps downstream and 91 kbps to 1.088 Mbps upstream for data, while
simultaneously providing lifeline POTS (Plain Old Telephone Service). Upstream is defined
as from CPE to network and downstream from network to CPE.
