Description
Temperature Harden and Friendly Remote-Installation Design The ZISA IA48V can operate in the environment with temperature from -40C to 65C, 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 the IA48V is installed in a residential neighborhood. The fan module is swappable in order to reduce the maintenance cost in the field. Complete ADSL2+ Services The IA48V 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 provide for subscriber who need even more bandwidth or located with loop length longer than 5000 ft.
VoIP Media Gateway Embedded The IA48V 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 IA48V 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 IA48V 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.
