2 DESCRIPTION OF THE DEVICE
2.1 Exterior design Desktop models
The front panel of the device has 3 LEDs:
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/ACT The LED is lit upon an incorrect connection to the LAN. The LED is blink upon the
detection of packets in the segment of the current LAN.
The back panel of the MDS932AE-10BT and MDS933AE-10BT modem has:

User Manual
Version: 1.2 Page. 9 of 25
• 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;
• “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.
The back panel of the MDS932AE -FXO/FXS modem has additionally:
• The “LINE1” and “”LINE2” connector to connect to PABX (FXO model) or to telephone
(FXS model).
