A T U R E S | Alcatel-Lucent 7710 SDH CMAs, 7710 SR SONET specification

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

7710 SDH CMAs, 7710 SR SONET specifications

The Alcatel-Lucent 7710 Service Router (SR) is a versatile platform designed to meet the demands of modern telecommunications networks. This high-performance device specifically supports Synchronous Optical Networking (SONET) and Synchronous Digital Hierarchy (SDH), providing robust transport and routing capabilities. The 7710 SR is integral for service providers looking to offer enhanced data and voice services over their existing infrastructures.

One of the primary features of the 7710 SR is its ability to support multiple service types, including Ethernet, IP, and legacy circuit services. This flexibility allows operators to transition smoothly from traditional telecommunications to newer, IP-based services. The platform also includes advanced Quality of Service (QoS) mechanisms, enabling operators to prioritize different types of traffic effectively. As a result, this ensures that time-sensitive applications, such as voice over IP (VoIP) and video conferencing, receive the necessary bandwidth and low latency.

An essential aspect of the 7710 SR is its scalability. The architecture is designed to accommodate growing network demands, with modular interfaces and high throughput capabilities. This enables providers to expand their networks and integrate new technologies with minimal disruption. The router supports a variety of physical interfaces, including OC-3, OC-12, and OC-48, allowing for extensive connectivity options.

The Alcatel-Lucent 7710 SDH CMAs (Carrier Multi-Service Aggregators) complement the 7710 SR by providing additional functionalities for network aggregation. CMAs facilitate the reliable transport of multiple service types over SDH networks, improving operational efficiency and reducing costs. They play a critical role in managing network traffic, offering concise visibility into performance metrics and service levels.

Security is another critical aspect of both the 7710 SR and the CMAs, incorporating advanced encryption and access control features to safeguard sensitive data. This focus on security ensures compliance with industry standards and protects against unauthorized access and cyber threats.

In terms of management, the 7710 SR and CMAs offer intuitive interfaces and comprehensive monitoring tools, enabling network operators to oversee operations effectively. This simplifies troubleshooting and maintenance, reducing downtime and improving overall service reliability.

In summary, the Alcatel-Lucent 7710 SR SONET and 7710 SDH CMAs represent a robust solution for today’s converging networks. With their rich feature set, scalability, and security, they address the evolving needs of service providers in an increasingly complex telecommunications landscape.
