As a leader in convergence solutions, Alcatel-Lucent expands its rich portfolio with a cost-optimized Compact
Media Adapter (CMA) for targeted applications. The DS1/E1 Asynchronous Transfer Mode (ATM) Inverse
Multiplexing over ATM (IMA) CMA is purpose-built to enable mobile cell-site backhauls and corporate branch
offices to integrate data into a traditional Time Division Multiplexing (TDM) infrastructure.
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
a hot-swappable, quarter-slot module
with 8-port DS1/E1 over integrated
RJ-48c interfaces, each capable of
delivering wire-speed performance.
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.
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
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.

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
