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 S2
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.
