CHAPTER 2: Introduction

2. Introduction

2.1 Description

The 2-Wire Short-Range DSL Line Driver (HDSL) V.35 or X.21 provides

high-speed 2-wire connectivity to ISPs, PTTs, and corporations using HDSL (High

Bit-Rate Digital Subscriber Line) technology. Supporting multiple line rates from

144 kbps to 1.168 Mbps, the Line Driver provides megabyte speeds to leased line,

LAN-to-LAN interconnection, and WAN access networks over 3.6 miles/5.8 km

(1.054 Mbps on 24-AWG/0.5-mm wire).

The HDSL Line Driver V.35 (ME0006A-V35) provides a V.35 interface on an M/34

female connector. The HDSL Line Driver X.21 (ME0006A-X21) provides an X.21

interface on a DB15 female connector. Features include loopback diagnostics, and

inband SNMP/HTTP remote management capabilities through a DSL Line Driver

Rack Card (ME0003C) CO and externally accessible configuration switches. Both

versions of the Line Driver are compatible with the popular QuikConnect HDSL

Line Driver (ME0007A-HDSL) standalone and DSL Line Driver Rack Card

(ME0003C) as well as the HDSL Line Driver 10BASE-T (ME0006A-10BT).

As a symmetric DSL NTU, the HDSL Line Driver offers the same data rates in both

directions over a single pair of regular telephone lines using 2B1Q modulation.

Line connection is made by an RJ-45 jack. The Line Driver is powered by a 100- to

240-VAC universal power supply.

2.2 Features

• High bit-rate DSL.

• 2B1Q modulation.

• DTE rates up to 1.152 Mbps.

• V.35 and X.21 interfaces.

• Interoperable with ME0003C and ME0007A.

• SNMP Manageable via Managed Micro Rack SNMP/HTTP Card (RM261C-

SNMP) through ME0003C/CO.

• Universal power supply.

• Front-panel status indicators.

• Small, convenient desktop unit.

• CE marked.

3. Configuration

The HDSL Line Driver is equipped with two sets of eight DIP switches. This

chapter describes switch locations and explains all possible configurations.

Configuring the Hardware DIP Switches

The 16 external switches are grouped into two eight-switch sets. They’re externally

accessible from the underside of the HDSL Line Driver (see Figure 3-1).

Figure 3-1. Underside of the HDSL Line Driver,

showing the location of the DIP switches.

The two sets of DIP switches on the underside of the HDSL Line Driver are called

S2 and S3. As Figure 3-2 shows, the orientation of all DIP switches is the same with

respect to ON and OFF positions.

Figure 3-2. Close-up of configuration switches

(all sets are identical in appearance).

CHAPTER 3: Configuration

DIP-S

WITCH

The configuration switches on S2 allow you to specify the clocking mode and to

enable/disable local and remote loop requests from the V.35 DTE. Default settings

are shown in Table 3-1.
