[. . . ] Ultra Symmetric High Bandwidth with Port Bonding Benefits End-to-end Solution for Symmetric Bandwidth Services With different firmware uploaded, the IES-708-22A/IES-708-22 can act as either a STU-C or a STU-R. [. . . ] The port-bonding feature not only provides higher symmetric bandwidth to subscribers, but also offers more reliable bandwidth pipes for business applications. Different TCPAM for Lower Power Spectrum Density The IES-708-22A/IES-708-22 supports 16-layer and 32-layer TCPAM modulations. Operators can select one of these in "auto" or "force" mode; the former determines the modulation by negotiating with the peer device, while the latter forces the use of configured modulation. In order to avoid the cross-line noise, many Telco operators restrict the power spectrum density for G. SHDSL service but allow the transmission rate of the links to increase. With the dual-modulation feature, the goal will be much easier to realize. 8-port G. SHDSL IP DSLAM with AC/DC Power Input Sophisticated Features for Triple-Play Services The IES-708-22A/IES-708-22 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 256, while each group can have 9 members. At least 30 IES-708-22A IES-708-22 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.
