2 Alcatel-Lucent 7710 SR SONET/SDH CMAs
As a member of the industry-leading
Alcatel-Lucent SR product portfolio,
the Alcatel-Lucent 7710 SR family
leverages the Alcatel-Lucent Service
Router Operating System (SR OS). As
such, it inherits the performance and
reliability of Alcatel-Lucent’s proven
feature set, including non-stop routing
and non-stop services, and meets service
provider, cable MSO and enterprise
requirements for IP/MPLS platforms
that are future-safe for innovative,
profitable service delivery.
Alcatel-Lucent 7710 SR CMAs
Alcatel-Lucent 7710 SR CMAs are small,
hot-swappable interface modules that
provide traffic interfaces in standard
Alcatel-Lucent 7710 SR I/O positions. A
CMA is a front-loading plug-in module
that allows selection from a variety of
interface speeds and types. The Alcatel-
Lucent 7710 SR-c4 supports up to four
CMAs, and the Alcatel-Lucent 7710
SR-c12 supports up to eight CMAs.
Each CMA has a 1.5 Gb/s bidirectional
connection to the control and forward -
ing module (CFM).
The Alcatel-Lucent 7710 SR provides
unprecedented service richness and flex-
ibility, with the capability to support any
service over any interface. All Alcatel-
Lucent 7710 SR service features, such
as service-based hierarchical quality of
service (H-QoS), accounting and filtering,
as well as service-aware operational
operations, administration and main -
tenance (OAM) tools, are available on
all interfaces and subinterfaces. Service
providers, cable MSOs and enterprise
customers can provision access ports
and IP or MPLS tunnels on any physical
interface of any CMA, with no additional
specialized hardware required. Table 1
lists CMA types and port densities for
the Alcatel-Lucent 7710 SR family.

SONET/SDH CMAs
With multirate SONET/SDH compact
media adapters (CMAs), the Alcatel-
Lucent 7710 Service Router (SR) provides
the most modular, compact solution
for service providers, cable MSOs and
enterprise customers’ smaller PoP, hub
site and WAN connection applications
and offers highly available and flexible
solutions for IP/MPLS edge consolidation.
The multirate SONET/SDH CMA hard -
ware supports two OC-3c/OC-12c or
STM-1c/STM-4c physical connections.
SONET ports can be individually con -
figured for either OC-3c or OC-12c
operation. SDH ports can be individ -
ually configured for either STM-1c or
STM-4c operation. The same 7750 SR
OC-3c/STM-1c and OC-12c/STM-4c SFPs
are supported to meet media type and
distance requirements.
SONET/SDH CMAs provide:
• SONET or SDH framing (software
selectable)
• Multirate OC-3c/OC-12c or STM-1c/
STM-4c interface speeds (software
selectable)
• APS protection can span CMAs, CMA
and MDAs and multiple chassis
• Support for network or access mode
• Transmit clock is node timed and
each port can enable or disable local
line and internal loopbacks
• BCP null, BCP.1Q, IPCP, PPP auto,
frame relay and WAN mirror
encapsulations are supported
• Full array of path alarms are config -
urable to be either enabled or disabled
• Link holdover timers can be configured
in 100ms increments to control link
up and link down indications
• Line signal degradation bit error rate
and line signal failure bit error rate
thresholds are configurable
• Multimode and single-mode
media types
• All ports use SFP optics for added
flexibility and optimal slot utilization
• Optical link budget supporting
distances up to 85 kilometers
(52.8 miles)
• In-service removal and insertion
FEATURES
The multirate SONET/SDH CMAs

IP VPN services
¬ dedicated Internet access services
¬ virtual private LAN service (VPLS)
¬ Ethernet virtual private wire
service (VPWS)
¬ frame relay VPWS
• High-performance IP and MPLS
tunneling
• Rich MPLS multiservice transit
capabilities
• Thousands of ingress/egress config -
urable access control lists (ACLs)
• Scalable BGP, open shortest path
first (OSPF) and intermediate system-
to-intermediate system (IS-IS) routing
implementations with traffic-engi -
neering extensions
• Per-service H-QoS
• Granular per-service accounting
and billing
• Extensive OAM tools for service-aware
troubleshooting and faster service
activation
