The Alcatel-Lucent Integrated Service Adaptor Ethernet Switch (ISA-ES) series circuit packs provide feature-rich Ethernet service capabilities for the undisputed market leaders of multiservice networks, the Alcatel-Lucent Optical Multiservice Network (OMSN) products.

ISA-ES1 and ES4 variants provide native Fast Ethernet (FE) and Gigabit Ethernet (GigE) interfaces and Ethernet over SDH (EoS) ports within 1-Gb to 2.5-Gb switching engines.

The Alcatel-Lucent OMSN family of multisevice nodes are deployed worldwide. The ISA–ES modules, with their capability to aggregate and switch Ethernet into SDH transport, offer service providers a powerful tool to leverage their SDH investments to offer Ethernet services.

	ES1	ES4	to stringent performance standards
			with high availability and layered
			network and service management.

SDH infrastructures built on the AlcatelLucent OMSN products have powerful Quality of Service (QoS) management with high availability and resiliency. Integrated Ethernet services based on the ISA-ES are simple to implement with embedded end-to-end data-service management. The ISA-ES empowers network transformation for service providers seeking to gain maximum return from their network investments (see Figure 1).

The ISA-ES series meets the Ethernet technology needs of Tier-1 and Tier-2 service providers, service-provider carriers, multisystem operators or mobile service operators (MSOs),cable operators, power utilities and government institutions.

Each ISA-ES module has a configurable IP address and User Datagram Protocol (UDP) port for the network management to manage Ethernet services, including implementation, alarms retrieval and QoS Performance Monitoring (PM).

ISA ES1 and ES4 circuit-pack overview

•Electrical and optical FE/GigE interfaces, with Small Form Factor Pluggable (SFP) optics

•A comprehensive set of:

¬Ethernet switching features (802.1d/Q/ad)

¬Resiliency features: xSTP, Link Aggregation Group (LAG), link capacity adjustment scheme (LCAS) and SDH-based protection

¬QoS features: for example, policing, priority marking, per class queuing and WDRR

¬Ethernet PM counters

¬Ethernet Operations, Administration and Maintenance (OA&M) suite (ITU-T Y.1731/IEEE 802.1ag)

•EoS adaptation suite, using generic framing procedure (GFP) (G.7041), link access procedure over SDH (LAPS), vitual concatenation (VCAT) (G.707) standards

•Flexible data architecture options (see Figure 2):

•Optical transport options within OMSN products:

¬Multiplex section protection (MSP): 1+1, 1+N

¬Multiplex Section-Shared Protection Ring (MS-SPRING) 2f

¬Subnetwork Connection Protection (SNCP) I/N

•Efficient network management with dedicated Ethernet manager suite

¬Point-to point

¬Hub and spoke

¬Multipoint-to-multipoint

Figure 3. SLA support

To help meet service level agreements (SLAs), each ISA-ES module allows service providers and carrier operators to specify per flow QoS. Traffic is specified by a set of parameters to control its maximum and mean rates and the relative burst window size in bytes (see Figure 3).
