A Complete Offering for High Bandwidth Asymmetrical Services — Residential Data, Voice, and Multiple Video Channels
Zyxel IES-1248-5x/IES-1248-5xA Series (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-1248-5x/IES-1248-5xA Series 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-1248-5x/IES-1248-5xA Series 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-1248-5x/IES-1248-5xA Series 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.
Temperature Harden and Friendly Remote-Installation Design
The IES-1248-51V provides state-of-the-art ADSL2+ connectivity to subscribers. The latest technologies like various line coding, power spectral mask fitting, dual latency path selection, loop diagnostic and power management capabilities, Seamless Rate Adaptation (SRA) and Impulse Noise Protection (INP) are all supported. Up to 24 Mbps (downstream) and 2.3 Mbps (upstream) per port facilitates high-bandwidth services such as streaming video, online gaming and IP TV. ADSL2+ port bonding is also provided for subscribers who need even more bandwidth or located with loop length longer than 5000 ft.
VoIP Media Gateway Embedded
The IES-1248-51V has a built-in POTS splitter and can act as the media gateway of a packet voice network. Through the communication with the softswitch or media gateway controller, the IES-1248-51V digitalizes and encapsulates the POTS voice into VoIP packets and delivers them to the IP network with higher priority in SIP or H.248 signal protocols. Telco operators can provide voice over broadband (VoBB) service without changing existing customer premises network and keep the OAM&P as usual.
Sophisticated Features for Triple-Play Services
The IES-1248-51V comes with complete ATM and Ethernet QoS, as well as various IP QoS features (Packet classification/Rate Limitation/Queue Scheduling). The seamless QoS-mapping not only allows consistent and appropriate traffic treatment of packets, but also enables fulfillment of triple-play services.
The number of the supported multicast groups is 512, while each group can have 50 members. At least 30 multicast IGMP join/leave requests can be processed in one second and the maximum channel processing time is less than 250 ms. For security, anti MAC address spoofing, broadcast storm prevention, MAC count limiting and packet filtering features are provided. With these features provided, Telco operators can easily offer Triple-play services like high-speed Internet access, VoIP, Near VOD, Broadcast TV and TV on Demand.
