Compatibility:
The Sigrand SG-16B 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.
The modem features the following interfaces:
•
one SHDSL interface (conforms to ITU-T G.991.2.bis standard) providing
the data rate range from 192 to 5696 kbps and the optional extended
range from 64 to 6016 kbps
•
two Ethernet 10/100Mb (IEEE 802.3) interfaces with Auto-Negotiation and
Auto MDI/MDI-X
•
one EIA-232C (RS-232C) interface for modem management.
