Introduction
The Black Box DSL Discovery device is targeted at the organization of high-rate access to Internet or at the
integration of LANs. The 2B1Q line encoding is used to transmit information over a twisted pair. The Black
Box DSL Discovery device ensures organization of communication over one or two twisted pairs. The device
provides transmission rates in the range from 192 Kbit/s to 4640 Kbit/s. The parameters of the device are
stored in the NVRAM with the help of a PC. The 10/100Base-T interface is used as a user’s interface. The
device can operate in the transparent bridge mode with the dynamic accumulation of MAC addresses.
The device is designed to organize a digital channel at the central office side and to connect this channel
with the Black Box DSL Discovery external unit installed on the customer premises side. It is also possible to
interconnect two stand-alone modems, for example, for the organization of communication between LANs.
The modems support uploading of new firmware versions using the Monitor port.

LOCAL(L)
informs the user about the status of the local device. The following four statuses are
possible
«blinking red»
informs the user about malfunctioning of the modem’s hardware and
software. In this case, the modem is out of order and should be submitted to
the service center for being repaired.
«red»
informs the user about an urgent alarm. An abruption of the connection, the
correspondence of the signal-to-noise ratio which does not allow transmitting
information and a great number of errored blocks can cause an urgent alarm.
See the “Command menu” chapter for detail.
«amber»
informs the user about non-urgent alarms. An abruption of connection over
the user’s interface can cause non-urgent alarms.
«green» absence of alarms. Normal functioning of the device.
REMOTE(R)
informs the user about the status of the remote device. At the time being the remote
configuring of modems is not provided.
Ethernet The LED is lit upon an incorrect connection to the LAN, blink when it is active
The LED is lit upon the connection to the LAN at 100 Mbit/s.
The front panel of the external modem has:
• The “-48VDC” power connector. The connection of the modem to the 220 V power supply is
implemented using an external power supply unit;
• the “Monitor” connector to control the modem and store statistics;
• “PC” and “HUB” connectors to connect the modem to the LAN using a straight Patch Cord (to the PC
or HUB, respectively);
• the “DSL” connector to connect the modem to the leased physical line.
Date 17.03.04 page 9 of 29
Rules of connection settings
It is necessary to stick to the following rules while configuring the modems:
• One modem should be set in the “MASTER” mode and the other should have this mode disabled.
Usually the “MASTER” mode is enabled on the provider or central office side because in this mode
the modem can affect the connection parameters.
• The value of “ADAPTIVE” parameters should be equal on both modems.
• For 4,6M connection, the value of “OPERATE” parameters must be set to “Transparent” on both
modems.
The time of connections in ADAPTIVE mode depends on the current line conditional and can be up to 5
minutes.
Examples of the modem configuration (for every line).
Parameters Modem 1 Modem 2
MASTER ON OFF
ADAPTIVE OFF OFF
LINERATE 2320 2320
The connection is established at a speed of 2320 Kbit/s.
Parameters Modem 1 Modem 2
MASTER ON OFF

The delivery set
The delivery set includes:
• the subscriber access device (a modem);
• the power supply source (an AC adapter); (for MDS931AE-2)
• the cable for the connection to the line;
• Patch Cord UTP5
• User manual.
If any problems occur, address to the vendor.
Connection rules
During the connection of the modem stick to the following rules:
For external models
• connect the modem using the “straight” Patch Cord cable to the hub
through the HUB connector or to the PC through the PC connector. Only one device can be
connected to modem jack at same time.
• connect the modem, if necessary, to the serial port of the PC through
the “MONITOR” connector using the “straight” modem cable;
• connect the modem to the line using the “DSL” connector;
• connect the power supply unit to the AC power system;
• connect the modem to the power adapter using the “-48VDC” connector;

• launch the hyper-terminal operation program on the PC.
For Rack Mount models
• insert modem card to shelf
• connect the modem using the “straight” Patch Cord cable to the hub
through the HUB connector or to the PC through the PC connector. Only one device can be
connected to modem jack at same time.
• connect the modem, if necessary, to the serial port of the PC through
the “MONITOR” shelf connector using the “straight” modem cable;
• connect the modem to the line using the “DSL” connector;
Communication parameters of the terminal configuration
Management of devices of Rack Mount type
The device rear panel contains the TTL management bus, organized according to the “point/multipoint”
scheme. The TTL-RS232 layer translator is on the rear panel of the device. The socket for the connection
to the terminal is on the rear panel as well. If ACU and CMU are installed in Sub-Rack, the management
socket is on the front panel.
To connect the terminal, it is necessary to use RS232 cable. While attaching the cable to the computer
COM-port, make sure the port is not occupied by the other device drivers (for example, mouse).
The terminal must be configured in the following way:
• Transmission rate: 9600 kbit/s;
• Transmission format: 8-N-1;
• Flow management: XON/XOFF;
• Terminal type: VT100.
At any one time only one device in the shelf can be logically connected to the management interface. The
device is chosen in accordance with the slot number, in which it is mounted. To choose the necessary
device, type <%SN>, where SN is the slot number.
Example: to select the modem, mounted in slot 3, type:
%03
The unit in the shelf displays %SN after the ECHO command is entered, where SN is the slot number.
After typing “ECHO”, the operator will receive a response from LTU devices, as it is shown below:
ECHO
%01 %02 %08 %10 %11 %12
Management of devices of Stand Alone type
The management terminal is connected to the MONITOR socket (DB9 type), which is on rear panels. The
requirements to the terminal configuration are analogous to those of Rack Mount devices. After the power
is on, the computer displays information about the device firmware loading. It is necessary to set the
following parameters to monitor the modem:
• transmission rate – 9600;
• data bits – 8;
• parity – none;
• number of stop bits – 1;
• flow control – XON/XOFF.
