1 Introduction

Thank you for purchasing the DSE USB ADSL Modem. You will find that it is an excellent product that is easy to install and use. This USB ADSL Modem combines an “always on” high speed Asymmetric Digital Subscriber Line (ADSL) connection to the telephone line, and a Universal Serial Bus (USB) connection to a host PC into a complete and effective system.

The USB ADSL Modem is compliant with the full-rate ANSI T1.413 Issue 2 and ITU G.dmt (G.992.1) ADSL standards, and with the splitter-less ITU G.lite (G.992.2) specification. This rate-adaptive solution is designed for Customer Premise Equipment (CPE).

This manual contains information regarding the installation, operation, and configuration of the USB ADSL Modem. Additionally, it outlines the use of the XH1172 configuration webpages.

2 Features & Specifications

Protocol and Device Driver Selection

This USB ADSL Modem takes advantage of the processing power available with today’s computers by eliminating the need for a separate micro controller supporting the ATM Segmentation and Reassembly (SAR) function, resulting in a cost-effective ADSL solution suitable for both full-rate and G.lite applications. Additionally, the host-based software supports industry standard functions such as PPP over ATM (PPPoA) per RFC 2364, PPP over Ethernet (PPPoE) per RFC 2516, Bridged/Routed Ethernet per RFC 2684/1483, and Classical IP over ATM per RFC 2225/1577.

Supported operating systems are Windows 98SE, Windows 2000, Windows ME, Windows XP and MacOS X. The USB version 1.1 specification is supported and is the preferred standard method to connect peripherals to modern-day PCs.

During periods of no data transmission, this USB ADSL Modem performs idle cell insertion and deletion thus unloading this task from the host PC. ADSL is a transmission technology used to carry user data over a single twisted pair line between the Central Office and the Customer Premises. The downstream (Central Office to Customer Premises) direction typically supports a much higher data rate than the upstream or return (Customer Premises to Central Office) channel. This asymmetric nature lends itself to applications like remote LAN access, Internet access, and video delivery.

Data rates up to 8 Mbps downstream and up to 1 Mbps upstream are supported for Full Rate ADSL. Data rates up to 1 Mbps downstream and up to 512 Kbps upstream are also supported for G.lite. Actual data rates depend on the transceiver implementation, loop length, impairments, and transmitted power.

The USB ADSL Modem Device is based upon a scalable architecture. This architecture enables the device to support splitter-less G.lite as well as splittered and splitter-less full-rate ADSL. G.lite enables telephone companies to deploy consumer oriented, “Always on” 1.5 Mbps Internet access services without the need for splitter equipment, micro-filters, or wiring changes at the customer premises.

Host Software

The host software NDIS miniport driver provided implements the ATM Adaptation Layer 5 (AAL5), which is composed of two sub layers:

1. The Segmentation and Reassembly (SAR) layer

2. The Convergence Sub layer (CS)

The AAL5 protocol provides virtual connections, which offer error detection, but not error correction, between end stations attached to the same network. The SAR sub layer transmitter segments the higher layer information into a size suitable for the payload of the ATM cells of a virtual connection. The receiver reassembles the contents of the cells of a virtual connection into data units to be delivered to higher layers.

During periods of no data transmission, the device, and not the host software driver, performs idle cell insertion and deletion, thus unloading this task from the host PC and unburdening the USB bus with unnecessary traffic.

The Convergence Sub layer performs message identification and clock recovery. Additionally, the CS of the AAL converts the user service information coming from the upper layer into a protocol data unit (PDU), and also carries out the opposite process at the receiver.

Unspecified Bit Rate (UBR) service is supported. It allows a connection to be established without specifying the bandwidth expected from the connection. The network makes no guarantees for UBR service: it establishes the route but does not commit bandwidth. UBR can be used for applications that have no delivery constraints and do their own error and flow control. Examples of potential uses of UBR are e-mail and file transfer, as neither application has real-time characteristics.

Constant Bit Rate (CBR) service allows a connection to be established with a specified expected bandwidth. CBR can be used for an application such as video delivery.

ADSL Operating Modes

Full Rate ADSL Modes

Both T1.413 and G.992.1 (G.dmt) line coding schemes are supported for downstream rates up to 8 Mbps and upstream rates up to 1 Mbps in 32 Kbps increments. User selection of mode is supported through the provided control panel; however, auto provisioning is supported so that the appropriate modulation is automatically selected based on what is supported by the DSL Access Multiplexes (DSLAM) at the Central Office.

When operating in one of the full-rate modes, the low (POTS) and high frequency (ADSL) bands must be separated with a filter. This can be done with either a service provider-installed splitter (known as “splittered ADSL”), or with the use of distributed micro-filters in line with each POTS device on the circuit (known as “splitter less full-rate ADSL”). Both deployment models are supported.

G.lite Splitter less Mode

G.992.2 (G.lite) splitter less mode is supported for downstream rates up to 1.5 Mbps and upstream rates up to 512 Kbps in 32 Kbps increments. User selection of mode is supported through the provided control panel; however, auto-provisioning is supported so that the appropriate modulation is automatically selected based on what is supported by the DSLAM at the Central Office.

When operating in splitter less mode, the low and high frequency bands do not need to be separated with a filter, and neither a service provider. Neither installed splitter, nor distributed micro-filters are required. G.lite mode supports power management by defining a set of power management states for the link and the use of the Embedded Operations Channel (EOC) to coordinate between the ATU-R and ATU-C.

LAN Mode

Bridged or routed Ethernet over ATM (RFC 1483/2864) and Classical IP over ATM (RFC 1577/2225) are supported in the LAN driver. These protocols provide LLC or VCMUX encapsulation for carrying network inter-connect traffic over a single ATM AAL5 Virtual Connection. LLC encapsulation is desirable when it is not practical to have a separate VC for each carried protocol, such as with an ATM network that only supports Permanent Virtual Circuits (PVCs). The provided NDIS 5 drivers automatically establish a “connection-less” calls using the defined PVC, and encapsulate Ethernet bridged frames.

WAN Mode

RFC-2364, PPP over ATM, is supported in the WAN driver. Point-to-Point Protocol provides a method of transporting multi-protocol packets over point-to-point links. Point-to-point links allow for services such as Link Control Protocol, Network-layer Control Protocol, and authentication. The PPP over ATM standard brings this point-to-point services to the ATM network where they are not inherently supported. The provided NDIS 5 drivers accept an empty dial string on a specific “link” or PVC from Windows Dial-up networking to establish a call, and encapsulate PPP frames. User selection of WAN or LAN encapsulation protocols can be done manually via the provided control panel. However, auto-configuration is supported with the provided installation wizard, so that the protocol mode is selected properly without user intervention.
