About the ZyXEL IES1248-51V

The ZyXEL IES-1248-51V can operate in the environment with temperature from -40deg.C to 65deg.C, which meets various Fiber-to-the-Node and Fiber-to-the-Curb environment conditions worldwide. A side-slip plug-in and pull-out mesh filter, which is cleanable and reusable, is equipped to make it dust-proof and suitable for open-air installations.

Moreover, the rotational speed of the fan module is automatically adjusted according to the system temperature. The feature not only extends the lifespan of the module, but also has lower audible noise, which is important if IES-1248-51V is installed in a residential neighborhood. The fan module is swappable in order to reduce the maintenance cost in the field.

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 24Mbps (downstream) and 2.3Mbps (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.

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, 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.

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.
