Benefits
Better utilization of bandwidth
The IES-1248-51 (DC Power Input) is an IP-based DSLAM that terminates all the ATM circuits and converts
traffic directly to deliver the most popular broadband IP services. It also provides a distinct advantage over
typical ATM-based DSL access system due to the fact that IP is the natural approach for data transmission.
It offers better bandwidth utilization, ease of use, as well as the low-cost advantage. With the highly
compact and temperature-hardened design, simple installation and easy adaptation to local POTS/ISDN
splitter requirements, the IES-1248-51 can be deployed in indoor and outdoor enclosures.
A robust, capable ADSL2+ solution
With this standalone ADSL2+ IP DSLAM, service providers can offer residential and business users access to
