Ethernet – From Enterprise to Carrier


Carrier Ethernet is a Service

• Carrier Ethernet is a ubiquitous, standardized, carrier-class SERVICE defined by five attributes that distinguish Carrier Ethernet from familiar LAN based Ethernet

• It brings the compelling business benefit of the Ethernet cost model to achieve significant savings

Carrier Ethernet

• Scalability

• Standardized Services

• Service Management

• Quality of Service

• Reliability

EtherAccess Product Portfolio


Smart Customer Ethernet Demarcation for EPL/EVPL Service

Description

• The more services become sophisticated, the more the need for intelligent demarcation for EPL/EVPL (Ethernet Private Line/Ethernet Virtual Private Line) services. ‘Intelligence’ in the E-NTU allows for end-to-end functionality with clear demarcation, service control and differentiation, OAM in order to guarantee the SLA.

Customer Benefits

• Remote smart demarcation reduces up to 80% the costs for remote assistance

• Extensive QoS capabilities allow offering a wide range of services per customer with SLA guaranteed

• Keep the mass market when providing equivalent SLA to those in traditional services

• Savings by reducing possible SLA penalties

Ethernet Wholesale Service

Description

• Service providers may require third party’s network to reach the end user (access provider). This may limit or avoid visibility across the access provider’s network. The ETX at the customer premises and possibly also collocated ‘between’ the networks give visibility across the access providers network with SLA verification.

Customer Benefits

• Reduced OpEx by using advanced Eth OAM monitoring and diagnostics for service provider segment and access provider segment

• Quick trouble shouting process, improve competitiveness and customer satisfaction

• Increased revenues by offering a wide range of SLA options

Ethernet Access over NG-SDH-Based Backbone with ETX

Description

• ETX provides Ethernet NTU to the access link to SDH/Sonet Network using the Ethernet tributaries of the NG ADM

Customer Benefits

• Reduce Opex and Capex by leveraging existing transport infrastructure

• Increased revenues by offering a wide range of SLA options

• Reduced OpEx by using advanced SLA monitoring and diagnostics for service provider segment and access provider segment

Out-of-Footprint Ethernet Connectivity

Description

• Providing Ethernet services where customer is out of the provider's footprint by leasing lines from a transport provider.

Customer Benefits

• End-to-end service control and SLA measurements using Ethernet service OAM allow SLA verification across the access provider’s network

• Keeps the same SLA to on-net and off-net customers

• Bonding n x E1/T1 for higher bandwidth

IP DSLAM and 4G Backhauling over SDH/SONET

Description

• IP DSLAM and WiMAX backhauling over SDH/SONET extending the reach of packet switch network.

Customer Benefits

• Reduce Opex and Capex by leveraging existing transport infrastructure

• Generate new revenues by expanding customer base

• Use of less complex Layer 2 technology (converters and channelized switch) for reduced maintenance costs

• Support for wide range of access data rates
