ZyXEL Communications IES-1248 User manual

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.
A robust, capable ADSL2+ solution
With this standalone ADSL2+ IP DSLAM, service providers can offer residential and business users
access to high-bandwidth services on demand; such as streaming video, online gaming, multimedia
applications and multiple video channels on a single network connection. The IES-1248 also offers
medium/small businesses and home offices IP connectivity, VPNs, VLANs, high-quality video
conferencing, long-reach Ethernet and legacy service interconnection, as well as asymmetric
connectiivity as fast as 24Mbps. The IES-1248 DSL solution for POTS/ISDN is a sophisticated ADSL2+
device wielding full compliance to existing standards, the latest DSL technology, compactness, low
power consumption, integration with existing platforms and network managemeability. The
combination of a superior line code, modern signal processing techniques and state-of-the-art ASIC
design add up to a compact, energy-saving ADSL2+ modem with excellent performance, transparent
backward ADSL/ADSL2 compatibility, robust interference resistance and flexible configurability.
