1. Modem description The set of the Sigrand SG-16BVo and Sigrand SG-16BVs modems is intended for corporate network applications. The modems allow to transmit two voice channels and one data channel simultaneously using the single pair only. The data channel of the modem features an Ethernet-bridge and can be used to connect various Ethernet 10/100 Base-T devices.
Manual line coding selection is available only in the console management mode – see chapter 3 of this Guide Compatibility: The Sigrand SG-16BV modem line coding is compatible with all Sigrand SG-16 series and Granch SBNI16 series modems. Limitations of compatibility: Interoperability with the Granch SBNI16 modems is supported only within the compatible data rate range from 64 to 4608 kbps.
10 . The specified reach is proved by testing at the Sigrand lab reference line. Full version of the rate table is available at our site www.sigrand.com. An actual reach may vary against the shown data due to variations of cable performance.

1.12 Appearance, controls, indicators and connectors. The Sigrand SG-16BV modem should be connected either to a computer equipped with an Ethernet or Fast Ethernet card or to an Ethernet-switch. We recommend to connect the modem to an Ethernet switch, not a hub, since our equipment is optimized for interaction with Ethernet switches.

Fig. 3 The “RATE” dial and the “SET” DIP switches (fig.3) specify operation mode of the DSL channel. The dial sets DSL channel data rate (fig.4). Fig. 4 The “SET1” DIP switch selects “Master/Slave” mode, the “SET2” switch defines a method of the DSL channel rate negotiation and the “SET4” switch sets a mode of modem management.
Rate is set locally on each modem SET3 57600 bps RS-232C console port (SET4= 9600 bps data rate SET3 ADPCM32 (SET4= Voice codec type PCM64 OFF) Modem management by console port SET4 mode by DIP switches The SET3 switch has different meaning depending on the modem management mode (SET4).
After you verify that the line comply with the aforementioned requirements - • Fix the supplied RJ-45 plug on the cable in accordance with figure 5. The Sigrand SG-16BV modem uses only one pair of pins, namely 4 and 5. Other pins are not assigned. •...
Both modes have certain advantages over each other so a user is free to choose either setup mode according to actual requirements for modem operation. Setup by switches is described here as the most simple method. Management by a terminal program is described in Chapter 3. To use setup by switches, set the SET4 switch to OFF state.
To operate properly peer-to-peer, the modems settings should match each other! Do not forget to configure the remote modem beforehand! 2.4.2 Rate selection guidelines Before setting the data rate you should have known the performance of the line the modems are intended for. If the line performance is unavailable, apply the following technique to select the proper data rate: •...
Baud rate (Bits per second) should be set to 9600 or 57600 in accordance with SET3 switch setting. Power on or reboot the modem. If the terminal has been set up properly, the following message appears on the screen: Sigrand SG-16B SHDSL modem V.2.5 Interface module ETH1/ETH2 Interface module M16-2Vs Initialization complete...
3.2 General purpose commands The modem is managed by a set of commands conventionally divided into two types: the “general purpose” commands such as help, info, update, default, reboot, and the interface management commands such as dsl and eth1/eth2. Capabilities of the console management mode allow to configure the DSL interface as well as to control the Ethernet interfaces.
The reboot command performs reset of the modem. : reboot Rebooting... Sigrand SG-16B SHDSL modem V.2.5 Interface module ETH1/ETH2 Interface module M16-2Vs Initialization complete The update command is used to update the modem firmware. Detailed procedure of firmware reprogramming is discussed in chapter 4 of this Guide.

3.3.2 Setting DSL rate Modems with firmware version 2.5 or higher have the ability to set DSL rate from a “master” modem. The ability to set the rate manually at the both ends of the line is supported as well. 3.3.2.1Setting DSL rate from “master”...
3.3.2.2 Setting DSL rate manually both sides If the lower rates (64 to 128 kbps) or the higher rates (5696-6016) are required, set the local control mode (dsl cfg local) for both modems. The Annex type can be set A or F, if both modems have firmware version 2.5 or higher.

When a voice channel is OFF, its bandwidth is reused for data channel. 3.5.3 Voice codec selection As mentioned before, the SG-16BVo/BVs modems support standard voice codecs G.711 и G.726. The G.711 codec (the PCM codec) requires 64 kbps of the total DSL bandwidth plus 8 kbps for signaling. The G.726 codec (ADPCM) can operate in the two modes, the 32 kbps mode and the 24 kbps mode, plus 8 kbps for signaling.
