AND
INDUSTRY CANADA
RADIO FREQUENCY INTERFERENCE STATEMENTS
This equipment generates, uses, and can radiate radio frequency energy and if not
installed and used properly, that is, in strict accordance with the manufacturer’s
instructions, may cause interference to radio communication. It has been tested
and found to comply with the limits for a Class A computing device in accordance
with the specifications in Subpart B of Part 15 of FCC rules, which are designed to
provide reasonable protection against such interference when the equipment is
operated in a commercial environment. Operation of this equipment in a
residential area is likely to cause interference, in which case the user at his own
expense will be required to take whatever measures may be necessary to correct
the interference.
Changes or modifications not expressly approved by the party responsible
for compliance could void the user’s authority to operate the equipment.
This digital apparatus does not exceed the Class A limits for radio noise emission from
digital apparatus set out in the Radio Interference Regulation of Industry Canada.
Le présent appareil numérique n’émet pas de bruits radioélectriques dépassant les limites
applicables aux appareils numériques de la classe A prescrites dans le Règlement sur le
brouillage radioélectrique publié par Industrie Canada.

CHAPTER 2: Introduction
2. Introduction
2.1 Description
The QuikConnect mDSL Line Driver provides high-speed 2-wire connectivity to
ISPs, PTTs, and corporations using mDSL (Multi-rate Digital Subscriber Line)
technology. Multi-rate DSL has the ability to deliver the maximum bit rate that a
twisted-pair line can accommodate. Supporting multiple line rates from 144 kbps
to 2.320 Mbps, the QuikConnect 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 QuikConnect mDSL Line Driver standalone allows DTE speeds from 64 kbps
to 2.3 Mbps in 64-kbps increments. Features include loopback diagnostics, inband
SNMP/HTTP remote management capabilities, and externally accessible
configuration switches.
As a symmetric DSL NTU, the QuikConnect offers the same data rates in both
directions over a single pair of regular telephone lines using Carrierless Amplitude
and Phase (CAP) modulation. Featuring replaceable DCE-DTE interface modules,
the QuikConnect can be configured for a huge range of V.24/RS-232, V.35,
RS-422/530, G.703, and X.21 applications. Line connection is made by an RJ-45
jack. The standard QuikConnect mDSL Line Driver is powered by a 100- to 240-
VAC universal power supply. The DC power supply option supports any DC input
between -40 and -60 VDC.
The plug-and-play feature allows you to configure the DTE rate for the link from
the mDSL Rack Card (ME0003C) at the central office. The standalone unit
(ME0008A) at the customer premise site will automatically configure itself to the
DTE rate of the rack card. Other configuration parameters fall to the default state.
This lets you handle configuration changes from a single end of the link.
2.2 Features
• DSL distances on just two wires using mDSL technology.
• DTE speeds n x 64 to 1.152 Mbps.
• 2-wire operation.
• Plug-and-play master or slave.

10
QUIKCONNECT MDSL LINE DRIVER
• SNMP network management with in-band management of remote units plus
advanced diagnostics and statistics using an Managed Micro Rack
SNMP/HTTP Card (part number RM261C-SNMP).
• Internal, external, or receive recovered clocking options.
• LED indicators for TD, RD, CTS, CD, DTR, TM, ER, and NS.

CHAPTER 3: Configuration
3. Configuration
The QuikConnect mDSL Line Driver is equipped with three sets of eight DIP
switches. This chapter describes switch locations and explains all possible
configurations.
3.1 Configuring the Hardware DIP Switches
The 24 external switches are grouped into three eight-switch sets, and are
externally accessible from the underside of the QuikConnect (see Figure 3-1).
Figure 3-1. Underside of the QuikConnect,
showing the location of the DIP switches.
The three sets of DIP switches on the underside of the QuikConnect will be
referred to as S1, S2, and S3. As Figure 3-2 shows, the orientation of all DIP
switches is the same with respect to ON and OFF positions.

CHAPTER 3: Configuration
3.2 Configuring the Software Switches
The QuikConnect mDSL Line Driver features a menu-driven command system that
allows you to monitor and configure your mDSL Line Driver. There are two modes
of operation for the Line Driver’s control port: Monitor and Configuration. These
are described in more detail in the sections that follow. After the setup instructions
for the mDSL Line Driver (Sections 3.2.1 and 3.2.2) is a description of how to
setup your VT100 (or equivalent) control port for use with the mDSL Line Driver.
3.2.1 M ONITOR
If you are configuring your mDSL Line Driver through the DIP switches and you
want to check your configuration or view the status of the Line Driver, you can do
so by accessing the control port. In this setup, you are not able to make
configuration changes to the Line Driver because the hardware DIP-switch settings
are controlling the configuration of the Line Driver. If you would like to use the
control port to configure your Line Driver, see Section 3.2.2.
3.2.2 C ONFIGURATION
If you would like to use the Line Driver’s control port to configure your unit, you
must set all of the DIP switches to the ON position. This will force the Line Driver
into the plug-and-play mode. (This configuration is also required if you intend to
have the Line Driver work in a plug-and-play environment or use the Managed
Micro Rack SNMP/HTTP Card [part number RM261C-SNMP] to configure the
unit.)
3.2.3 VT100 T ERMINAL S ETUP
1. Connect the serial RS-232 port of a VT100™ or similar DTE with terminal
emulation to the control port of the Line Driver. To construct an RS-232 to
EIA-561 patch cable, refer to the control port pinout diagram in Appendix C.
2. Power up the terminal and set the RS-232 port as follows:
9600 baud
8 data bits, 1 stop bit, no parity
Local echo
CR-CR/LF on inbound data
ANSI, VT100 emulation
3. Power up the Line Driver.
4. After the Line Driver is powered on, the control port will display the Main
menu screen. If the Main menu isn’t shown, please review your VT100 setup
as described above.

18
QUIKCONNECT MDSL LINE DRIVER
3.3 VT100 Terminal Configuration
You can configure the Line Driver using a VT100 compatible terminal (or
program). With the VT100 interface, you can perform all functions available via
the DIP switches. The VT100 operation is available from the Main menu page.

The Main menu screen for the Line Driver is displayed in Figure 3-3. You can press
Esc to refresh this screen at any time. If you are running in the Monitor mode, the
Line Driver will not require a password. If you want to run in the Configuration
mode, you will be required to enter a password to access to configuration menus.
The default password shipped with the Line Driver is “blackbox” (all lower case).
The Line Driver is case-sensitive and will not work if the correct password is not
installed. If an incorrect password is entered, you will receive an error message and
be prompted for the password again. We suggest that you change your password
after setting up your Line Driver to ensure security for your network.
