1 INTRODUCTION
The Black BoxDSL Discovery is targeted at the organization of high-rate Black Box to Internet or at
the integration of LANs. The 2B1Q line code is used to transmit information over a twisted pair. The
Black BoxDSL Discovery ensures organization of communication over one twisted pair. The device
provides transmission rates in the range from 192 Kbit/s to 2320 Kbit/s. The parameters of the
device can be set both using switches or 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 on the customer premises side and to connect
this channel with the Black BoxDSL Discovery rack-mount unit installed at the central office 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.

3.1 Exterior design
Exterior design is introduced at the picture
The front panel of the device has five LEDs:
Page 7 of 30
User Manual
LOCAL 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 to transmit 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 informs the user about the status of the remote device. At the time being the remote
configuring of modems is not provided.
LINK The LED is lit upon an incorrect connection to the LAN.
ACT The LED is lit on upon the detection of packets in the segment of the current LAN.
10/100 The LED is lit upon the connection to the LAN at 100 Mbit/s.
The back panel of the modem has:
the grounding bolt of the modem (option); •
•
•
•
•
•
The “AC12V” 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;
switches to set operation modes of the modem in “field” conditions;
“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.

ОN Setting of the parameters of the modem with switches
ON The «MASTER» mode is enabled. This mode is usually set on the
provider or the central filter side
2

User Manual
3.3 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 “ADAPTIVE” mode should be either enabled or disabled on both modems.
In case when the “ADAPTIVE” mode is disabled, the line rates on both modems should be set
equal.
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.
Parameters Modem 1 Modem 2
MASTER ON OFF
ADAPTIVE ON ON
LINERATE 2320 Any
The connection is established at a speed of 2320 Kbit/s.
Parameters Modem 1 Modem 2
MASTER ON OFF
ADAPTIVE OFF OFF
LINERATE 192 192
The connection is established at a speed of 192 Kbit/s.

7 STORAGE CONDITIONS
The equipment of the Black Box family while being packed should withstand all means of transport
at a temperature in the range form -50
о
С to +50о С and the relative humidity of air up to 100% at 25
о
С. The equipment can also withstand air-transport at a low air pressure of 12 kPa (90 Torr) at -50о С.
The packed equipment of the Black Box family can be stored within 12 months (from the date of
transshipment including transporting time) in storage rooms without heating at -50
о
С - +50о С and
the mean monthly value of the air humidity of 80% at 20
о
С; short-term increases of air humidity up
to 98% (no more than a month a year) at a temperature not exceeding 25
о
С without moisture
condensation is admissible.
The equipment should be stored in storage buildings, which protect the devices from atmospheric
precipitations. The equipment should be kept on shelves or in factory packages in the absence of
vapors of acids, alkali and other atmospheric impurities.

8 GUARANTEE
The mean time before failure is no less 30000 hours.
The manufacturer guarantees that the equipment are in all respects in accordance with the
requirements of technical conditions when the customer follows the rules and conditions of
storage, transporting and maintenance.
The guarantee period (no less than 12 months after putting the equipment into operation) is
specified upon drawing the Contract for the sale of the equipment.
Should the equipment prove defective during the guarantee period, the manufacturer
undertakes to remedy the defects or replace the faulty equipment. If the defects appear due
to incompetent storage, maintenance and transporting, the guarantee does not cover such
defects.
After the guarantee period expires, the manufacture provides paid delivery of spare parts.
The list of spare parts and terms of their delivery during the operating lifetime of the
equipment should be specified in the Contract.
