1. Description of the modem
Sigrand modems «SG-17B» are SНDSL-modems with Ethernet interface
designed for integrating distributed local networks and connecting remote
computers and devices that are supplied with Ethernet interface.
Feature of a num ber of modification modem (SG -17B-261, SG-17B-161) is
the ability to obtain, and for modifications (SG-17B-441, SG-17B-351) the
possibility of filing, remote powering through a SHDSL line (Power-overDSL). Feature to obtain is available when the modem is used in
combination with the following equipment produced by « Sigrand »:
• DSLAM SG-17S ( with interface modules MS-17H4P2);
• Router SG-17R (with interface modules MR-17H1P2 and MR-
17H2P2);
• Regenerators SG-17E2P-SLG;
• Modems modifications SG-17B-441, SG-17B-351;
Modems SG-17B-111, SG-17B-121, and SG-17B-141 are powered from a
local power source with voltage 3.3, 12, or 48 V - in this case, SG-17B
modems can be operated in combination with Sigrand non-function of the
remote powering:
• DSLAM SG-17S ( with interface modules MS-17H4);
• Router SG-17R (with interface modules MR-17H1 and MR-
17H2);
• Modems SG-17B of various modifications.
Ethernet interface of modems SG-17B-541 and SG-17B-261 allows
connection of devices powered through Power-over-Ethernet technology
(IEEE 802.3af standard, Class2). Also modems modification SG-17B-151
and SG-17B-351 can be powered by technology Power-over-Ethernet
(IEEE 802.3af standard, Class1, Class3).
A full list of modificat ion series modem S igrand SG-17B is shown in table 2
(page 11).

The interface of SHDSL modem complies with ITU-T G.991.2.bis version
(the version of 2005) and uses the TCPAM – Trellis-Coded Pulse Amplitude
Modulation encoding set for data transfer.
The modem is equipped with the following interfaces:
• one SHDSL interface (ITU-T G.991.2.bis standard) operating in
the bitrate range 192-15296 Kb per second;.
• one Ethernet interface 10/100Mb (IEEE 802.3) with the options of
automatic rate adjustment and auto-sensing MDI/MDI-X;
• one RS-232C interface for managing the modem.

1.1.1. Communication range and bitrate of Sigrand modems
Brief information on communication range and bitrate of Sigrand SG-17B
modems is given in Table 1. The results were obtained with the length of
lines providing the value of Bit Error Rate (BER) equal or less than 10
-7
. The
specified value of comm unication range is proved e xperimentally at the test
communication line of Sigrand Laboratory. T he c omplete Table of bi trates is
shown at www.sigrand.com. The actual results shown at a real
communication line may differ from the specified values because of
possible diversiti es in the parameters of the lines.
