- The fastest way to achieve positive revenue returns associated with triple-play bonded ADSL2+ gateways is to deliver these services over existing copper loops, of which there are over 450 million worldwide
- Bonded ADSL2+ delivers great data rates over longer distance than the basic ADSL2+
- Lower CAPEX on investing equipment, lower OPEX for matured SNMP and TR069 network management and provision equipments
Annex M is an optional specification in ITU-T recommendations G.992.3 (ADSL2) and G.992.5 (ADSL2+). This specification extends the capability of commonly deployed Annex A by more than doubling the number of upstream bits. The data rates can be increased easily depending on the distance from the DSLAM to homes of the customers. It complies with G.992.1 (G.dmt) Annex A compliant/G.992.2 (G. Lite), Annex A/L/M and G.998.1 (G. Bond-ATM) ATM-based multi-pair bonding.
Loop bonding technology provides the telecom industry with a revolutionary technique to combine multiple ADSL2+ connections into a single, aggregated connection. Supporting up to 48 Mbps downstream and 2 Mbps upstream data rates, as well as high-speed data and derived voice applications, service providers can offer advanced bandwidth-dependent services such as broadcast video and video-on-demand (VOD) to customers beyond the reach of central offices or digital loop carriers. Bonded ADSL2+ supports multiple high-definition television streams at significantly longer distances than other existing xDSL technologies.
ZyXEL’s boneded ADSL2+ with Annex M solution on the existing networks for Telcos and service providers. The solution offers downstream bandwidth of up to 48 Mbps and upstream bandwidth of up to 5 Mbps using the bonding and Annex M technologies on two phone lines. We also offer a solution for bonding a larger number of phone lines; ZyXEL generally recommends the use of standard G.998/G. Bond technology for bonding multiple ADSL lines. The alternative solutions based on non-standard bonding or load-balancing techniques such as IP tunneling may have a role to play in certain deployments and we can provide
solutions of this type too.
ZyXEL’s bonded ADSL2+ with Annex M solution provides the existing ISPs with opportunities to target the profitable SOHO and SMB markets by differentiated and customized services. The superior downstream and upstream capabilities of bonded ADSL2+ combined with relatively low cost makes the solution particularly attractive to SOHO and SMB users. The significant attraction to the existing ISPs is that only part of their existing infrastructures needs to be upgraded and this can be achieved on a gradual basis as
subscription to the services increases.
ZyXEL’s bonded ADSL2+ with Annex M solution allows service providers to double the bandwidth over the existing copper infrastructure and thus leverage their investment to quickly deploy revenue-generating services like IPTV, VoD and other premium triple-play applications.
With the ZyXEL end-to-end bonded ADSL2+ solution,service providers can economically offer services with higher bandwidth coupled with 802.11n home networking solutions to their subscribers. This is a prime example of ZyXEL’s commitment to building exactly what operators need to remain competitive. Please refer to the application diagram and supported product tables for details.
