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