G.SHDSL Rackmount Solution 3000 series

The 3000 Series offers different ways to connect customers over high-speed DSL services, either with a G.703 or with a multi-protocol serial DCE port or Ethernet port. The multi-protocol serial DCE port can be configured as a V.35, X.21, RS-449 and RS-530 connection. The G.703 interface will carry 2.048Mbps/1.544Mbps and the multi-protocol serial DCE port transfers data up to 2313kbps.

3000 Series is equipped with an adaptive auto rate capability that identifies the maximum line rate supported by the copper loop. This powerful automatic configuration capability makes installation and service provisioning simple and painless. Further flexibility is provided by the ability to manually set the maximum speed at different levels for different customer-tailored service offerings.
