ATM to Ethernet ATM DSLAM Migration

We are world leaders in legacy migration solutions. With IP migration we enable end customers to retain equipment running legacy protocols, such as X.25, Leased Line and ATM.


ATM TO ETHERNET DSLAM MIGRATION


MIGRATE DSLAM INTERFACES TO ETHERNET


HOW THE SOLUTION WORKS

Many telcos have a large installed base of ATM DSLAMs but have a requirement to make use of their Ethernet backbone networks while the ATM core networks are being run down or decommissioned.
The lifetime of the existing DSLAMs can be extended by converting between ATM and Ethernet at the trunk side of the DSLAM.

Existing ATM DSLAMs can be adapted for use over Ethernet by either:

1. Providing ATM pseudowires across the Ethernet backbone network

or

2. Terminating the ATM in the GW7900 and converting between PPPoA and PPPoE, or PPPoEoA and PPPoE.

SOFTWARE/HARDWARE

The GW7900 has several interface options with either dual/quad OC-3/STM-1 WAN interface or a single OC-12/STM-4 interface.

High availability can be provided through two separate Gigabit Ethernet links.

  • ATM to PWE conversion
  • PPPoA to PPPoE conversion
  • High performance network processor provides wire-speed cell and packet processsing
  • Two OC-3 STM-1 SFP ports, quad OC-3/STM-1 SFP ports or single OC-12/STM-4 SFP port
  • Two gigabit Ethernet SFP ports
  • Supports copper or fibre SFPs
  • Single 10/100 management Ethernet port
  • Single RS232 console
