Compatibility:
The Sigrand SG-16G modem line coding is compatible with all Sigrand SG-
16 series and Granch SBNI16 series modems.
The modem eatures the ollowing inter aces:
•one SHDSL inter ace (con orms to ITU-T G.991.2.bis standard)
providing the data rate range rom 64 to 2048 kbps.
•one Е1 inter ace (G.703/G.704, 2048 kbps).
•one EIA-232C (RS-232C) inter ace or modem management.

1.1.1 Maximum reach per ormance
Brie in ormation about the maximum reach per ormance o the Sigrand SG-
16G modem is shown on Table 2. The Bit Error Rate (BER) at the maximum
reach is equal to or less than 10-7. The speci ied reach is proved by testing
at the Sigrand lab re erence line. Full version o the rate table is available at
