Features & Benefits:
- The fastest speed with the most advanced and
flexible DSL transport available, adjustable speeds
for multiple service offerings down/up stream up
to 24/1.2 Mbps
- Application flexibility, with asymmetric data
transport over a single copper pair (software configurable)
- Compliant with ITU, ANSI and ETSI standards
- POTS/ISDN in overlay mode
- Deployment from CO, cabinet or basement, multi-tenant
units/multi-dwelling units
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.
The IES-1248-51 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 high-bandwidth
services on demand; such as streaming video, online
gaming, multimedia applications and multiple video channels
on a single network connection. The IES-1248-51 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 connectivity as fast as 24Mbps. The IES-
1248-51 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 manageability.
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.
Service Applications:
- A complete service offering bundling data, voice
and video services
- Residential: broadband Internet access, streaming
audio and video, gaming, high quality video distribution,
VoD, and telecommuting
- Medium and small businesses: IP connectivity,
VPNs, VLANs, high quality video conferencing, long
reach Ethernet or legacy service interconnection,
asymmetric to 24 Mbps
- Low cost reliable transport for backhauling
applications, such as mobile base station connectivity
over ADSL
- VoDSL services, legacy services and WAN interconnection,
bridging or routing, VPNs, provided through appropriate
CPE
- Cost-effective broadband access for higher margin
services such as VoD, gaming, and multimedia applications
