Benefits
Better utilization of bandwidth
The IES-1248 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 can be deployed in indoor and outdoor enclosures.
