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 per-port

line rate can be configured as 2.3 Mbps, 4.096 Mbps or 5.69 Mbps. When configured as a STU-C, the IES-708-

22A/IES-708-22 can work with the P-791/P-792 to provide 2-wire G.SHDSL connections, work with the P-793 to

provide 4-wire G.SHDSL connections, or work with another IES-708-22A/IES-708-22 (in STU-R mode) to provide

16-wire G.SHDSL connections. If configured as a STU-R, the IES-708-22A/IES-708-22 can work with various SLC

line cards in the IES DSLAM portfolio.

Robust Ultra-high Bandwidth for Business Applications

With the ATM-based multi-paired bonding feature, the IES-708-22A/IES-708-22 supports up to 8 bonded

groups and 8 member links in each group. All upper-layer traffics of a bonded group will be segmented and

transmitted over the member links. If one of the member links fails, the conveyed traffic will be moved to other

working links; when the failed link recovers, it will seamlessly return to the bonded group and share the

transmission of the upper-layer traffic.

Within a bonded group, the underlying bit rates of the individual ports can be freely and independently

changed by their respective PHY layer. 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.

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

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. Triple-play services like high-speed Internet access, VoIP, Near VOD,

Broadcast TV and TV on Demand can be easily provided as well.
