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

2-WIRE IDSL LINE DRIVER RACK CARDS

2. Introduction

2.1 Description

The 2-Wire IDSL Line Driver Rack Card allows synchronous or asynchronous data
to be transmitted up to 11 miles (17.7 km) over one or two twisted pair (2- or
4-wire). Supporting synchronous speeds up to 128 kbps and asynchronous speeds
up to 38.4 kbps, the Card is perfect for LAN interconnection or high-speed
Internet links.

To compensate for poor line quality, the Card supports 2B1Q encoding, automatic
equalization, and auto gain control. The Card is fully SNMP manageable using the
Managed Micro Rack SNMP/HTTP Card (part number RM261C-SNMP). Software
configuration is performed via the VT100™ screens. Swappable interface driver
boards and interface cards allow you to easily change applications between
10BASE-T, G.703, RS-530, V.24, V.35, or X.21. The Card also features convenient
front-panel diagnostic switches and LEDs that allow for easy setup, configuration,
and testing.

The Card is designed to fit into the 16-Port Managed Micro Rack (part number
RM260), a 2U-high (3.5") rack chassis. This chassis uses a mid-plane architecture,
allowing front cards to be plugged into different rear cards.

2.2 Features

• Synchronous data rates of 19.2, 32, 56, 64, and 128 kbps in all clock modes.

• Asynchronous data rates: Up to 38.4 kbps.

• SNMP manageable using the Managed Micro Rack SNMP/HTTP Card (part
number RM261C-SNMP).

• Full-duplex operation over one or two twisted pair (2- or 4-wires).

• Point-to-point distances up to 11 miles (17.7 km).

• Remote digital loopback, local line loopback diagnostics.

• Internal, external, or receive recovered clocking options.

• LED indicators for TD, RD, CTS, CD, DTR, TM, ER, and NS.

• Fits in the Managed Micro Rack (part number RM260), a 2U (3.5") rack
chassis.

CHAPTER 2: Introduction

2.3 SNMP Management

The QuikConnect IDSL Line Driver (ME0009A) is SNMP manageable when
connected to a rackmounted 2-Wire IDSL Line Driver Rack Card (ME0001C).
SNMP management is enabled through a Managed Micro Rack SNMP/HTTP
Card (RM261C-SNMP) located in the 16-Port Managed Micro Rack (RM260).

HTTP/HTMP M

ANAGEMENT

The SNMP/HTTP Card maintains HTML pages that can be viewed through a Web
browser. You can display remote statistics and configure QuikConnect parameters
simply by entering the SNMP/HTTP Card’s IP address into the browser.

3. Configuration

This chapter describes the hardware and software configuration switches and
jumpers. Refer to the Managed Micro Rack SNMP/HTTP Card (RM261C-SNMP)
users’ manual for SNMP options.

3.1 Hardware Setup

The 2-Wire IDSL Line Driver front card defaults to the use of hardware switches
for configuration. The front card has an interface driver board, two eight-position
DIP switches, and one 4-position DIP switch (see Figure 3-1).

Figure 3-1. Configuration switches and the interface driver board

on the front card.

CHAPTER 3: Configuration

Figure 3-2 shows the orientation of the DIP switches with respect to the ON and
OFF positions.

NOTE

The ON position is oriented toward the front of the Card.

EVERSIBLEINTERFACEDRIVERBOARD

The 2-Wire IDSL Line Driver Rack Card features switchable interface driver boards
that allow a wide range of DTE interface connections. Figure 3-3 shows the
interface driver board on the top of the PC board.

2-WIRE IDSL LINE DRIVER RACK CARDS

Follow the instructions below to select the correct interface for your application:

1. With the 2-Wire IDSL Line Driver Rack Card pulled out of the rack chassis,
locate the driver board on the top of the front card.

2. Lift the interface board gently off of the PC board.

3. Locate the correct interface on the bottom of the driver board. For
example, the RS-232/V.35 interface board is marked “THIS SIDE UP FOR
RS-232” on one side and “THIS SIDE UP FOR V.35” on the other side.

4. Re-orient the interface board into the socket with the appropriate interface
pointed UP and with the arrow pointing toward the front panel of the PC
board.

5. Push the interface driver board gently onto the socket and re-install into the
rack system.

Switch S1-4: Management Setting

When setting the SNMP management, the DTE rate switches (S1-1, S1-2, and S2-1)
need to be in the ON position. Therefore, to set a Rack Card to SNMP
management mode, the following switches have to be at the ON position: S1-1,
S1-2, S5-1, and S1-4. Use Switch S1-4 to configure the Rack Card’s management
setting.

S2

The 2-Wire IDSL Line Driver Rack Cards may be configured by a menu-driven
software system when used with the Managed Micro Rack Control Module,
VT100™ (part number RM262C) or Managed Micro Rack SNMP/HTTP Card,
SNMP (part number RM261C-SNMP). In order to configure the 2-Wire IDSL
Line Driver Rack Card by software commands, you must set its control port
address.

The control port address is defined by a two-digit decimal number. Switches S2-1
through S2-4 define the least significant digit or the “ones” digit, and Switches S2-5
through S2-7 define the “tens” digit. Valid addresses are 0 through 79. Use
Table 3-6 and the instructions that follow the table to set the control port to the
desired address.

Switches S2-1 through S2-4: Control Port Address— LSD

Use Switches S2-1 through S2-4 to set the least-significant digit of the ME0001C
control port address. For example, using Table 3-6, if the desired address is “63”,
the “3” is the least-significant digit in the address. Set Switches S2-1, S2-2, S2-3, and
S2-4 to OFF, OFF, ON, ON.

Switches S2-5 through S2-7: Control Port Address—MSD

Use Switches S2-5 through S2-7 to set the most-significant digit of the ME0001C’s
control port address. For example, using Table 3-6, if the desired address is “62,”
the “6” is the most-significant digit in the address. Set Switches S2-5, S2-6, and S2-7
to ON, OFF, OFF.

3.2 Configure the Software Switches

The 2-Wire IDSL Line Driver Rack Card features a menu-driven command system
that allows you to configure the local card. The software control port signals of the
ME0001C are carried to each card in the rack along the internal power bus board.
Access to all rack card control ports is provided by a single Managed Micro Rack
Control Module (see the RM262C users’ manual). After setting the control port
address (see Section 3.1.3), use the following instructions to configure the unit.

2-WIRE IDSL LINE DRIVER RACK CARDS

1. Connect the serial RS-232 port of a VT100 or similar DTE with terminal
emulation to the EIA-561 control port on the Managed Micro Rack Control
Module (RM262C). To construct an RS-232 to EIA-561 patch cable, refer to
the control port pinout diagram in Appendix B.

2. Power up the terminal and set its 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. Press [CTRL+B] on the terminal followed by the two-digit control port
address.

4. To make a selection from any menu, enter the option number. To exit any
menu without making a selection, press the [ESC] key.

5. After the 2-Wire IDSL Line Driver Rack Card is powered on, the control port
will send out this message:

Model: ME0001C software version xx

6. Press [ESC] on the terminal.

7. The 2-Wire IDSL Line Driver Rack Card will then display the Main Menu
screen. You may configure the Local Card from this screen.

IMPORTANT!

To make a selection from any menu, enter the option number. To exit
any menu without making a selection, or to return to the previous menu,
press the [ESC] key.
