The DS1/E1 ATM IMA CMA is supported on the Alcatel-Lucent 7710 Service Router (SR-c4) and the 7710 SR-c12. The Alcatel-Lucent ATM IMA CMA is
ahot-swappable, quarter-slot module with 8-port DS1/E1 over integrated RJ-48c interfaces, each capable of delivering wire-speed performance.
Purpose-built to extend the success
of Alcatel-Lucent 7710 SR at the carrier network edge, the ATM IMA CMA is optimized for cost and density, while ensuring standards compliance, service richness and service assurance common to all Alcatel-Lucent Service Router Operating System (SR OS) platforms. The ATM IMA CMA enables simultan eous service layer applications such as Internet enhanced services (IES), virtual private routed networks (VPRNs), virtual private LAN services (VPLS) and virtual private wire services (VPWS) to run without adverse impact on the performance.
In the frameworks of 2.5 G and 3 G mobile data delivery, ATM is recog nized as a transport to deliver IP data services. Using IMA for channel
aggregation, ATM can seamlessly integrate and scale TDM bandwidth for delivery of media-rich data services. The ATM IMA CMA is Alcatel-Lucent’s answer to mobile operators intending to take advantage of the well- entrenched TDM infrastructure and gain a competitive advantage with quick and non-disruptive backhaul upgrades to the radio access network (RAN) sites.
Not limited to just mobile applications, the ATM IMA CMA also enables wireline service operators to offer very flexible voice and data service deliveries. Any corporate branch offices within its coverage area can easily subscribe
to the Ethernet pay-as-you-go service between 1.5 Mb/s to 16 Mb/s, with 1.5 Mb/s or 2 Mb/s bandwidth increments. Such flexibility and granularity were previously unavailable with TDM- based service. When coupled with stringent ATM quality of service (QoS), the ATM IMA CMA enables wireline service operators to broaden the reach of their business services.
