Reduces OpEx by Enabling Remote Monitoring of Access Link Quality
RAD Data Communications, the industry leader in Carrier Ethernet access solutions, has become the first vendor to introduce a cost-optimized SHDSL.bis modem that incorporates Ethernet OAM (Operations, Administration and Maintenance).
RAD’s ASMi-54L now ensures that service providers will be able to offer their customers QoS (Quality of Service) for their Ethernet applications.
“The era of ‘best effort’ is passé,” states Meira Erez, Product Line Manager at RAD Data Communications. “End users are looking for QoS, and they demand it where their applications start, which is the First Mile,” she continues.
“And, until now, that’s historically been the network’s weak link for service providers and vendors alike.”
Ethernet OAM is the key to the successful deployment of carrier-grade Ethernet services because it enables providers to detect line faults.
Moreover, such capabilities allow providers to better design their service offerings.
“Deploying access equipment that features Ethernet OAM capability is a huge advantage for network operators because they can verify line quality via the management system before a service becomes available to the customer on the one hand while, on the other, it immediately detects faults from a central site and facilitates their rectification after the service is up and running, thus minimizing their effect on users,” Erez notes. “This frees service providers from having to send a technician to the customer premises every time a fault is detected, cutting down expensive truck rolls to reduce OpEx, while greatly increasing response time and customer satisfaction,” she adds. “Such capabilities make the ASMi-54L a powerful – yet economical – SHDSL.bis access device, with functionality well beyond that of simple modems.”
Incorporates IEEE 802.3-2005
The ASMi-54L incorporates Ethernet link OAM based on the IEEE 802.3-2005 (formerly 802.3ah) standard. This enables network operators to monitor the performance SHDSL.bis access links that typically connect the service end-points, such as customer premises, to the network edge.
The ASMi-54L supports increased throughput for Ethernet services of 15 Mbps over 2-wire and up to 30 Mbps over 4-wire, using RAD’s high performance SHDSL technology. Alternatively, it supports data access rates of up to 5.7 Mbps over 2-wire and 11.4 Mbps over 4-wire lines, using standard Ethernet in the First Mile (EFM) bonding at a distance of up to 2.6 kilometers (1.6 miles). In addition, the modem supports both Ethernet and E1 over the same DSL connection.
AXCESS+ Solutions Portfolio
The ASMi-54L is part of RAD’s AXCESS+ multiservice access and First Mile solutions portfolio. AXCESS+ offers a wide variety of narrowband and broadband data rates over fiber, copper and wireless infrastructure. AXCESS+ provides a smooth migration path from legacy to next generation packet switched networking and services.
RAD UNVEILS COMBO TDM AND ETHERNET EFM NETWORK TERMINATION UNIT AT BROADBAND WORLD FORUM EUROPE
At Broadband World Forum Europe 2010, RAD Data Communications is premiering a solution that provides broadband access for E1/T1 and Carrier Ethernet services over bonded SHDSL.bis lines.
RAD’s LA-210 Ethernet in the First Mile (EFM) DSL Network Termination Unit
(NTU) is installed at customer premises to deliver EPL and EVPL Carrier Ethernet services, together with legacy TDM services, to enterprises.
“With its new pseudowire capabilities, the LA-210 is ideal for leased line replacement, which allows carriers to migrate their legacy services, such as PBX connectivity, to packet switched networks,” notes Ami Barayev, RAD’s LA-210 Product Line Manager. “This solution significantly reduces the OpEx that would otherwise have to be spent on maintaining legacy infrastructure, while continuing to supply the deterministic service quality that is required for real-time applications,” he continues. ” Such multi-generation support in a single device also translates into lower CapEx, which makes the transition to next generation communications easier and cost-effective.”
Carrier-Grade Ethernet Capabilities, TDM and Synchronization over Packet in a Single Device
Working opposite next-generation IP DSLAMs and MSAPs (multiservice access platforms),The LA-210 features advanced service management capabilities, including Ethernet quality of service (QoS), end-to-end Ethernet OAM and service level agreements (SLA) performance monitoring. These are enhanced with standards-based SAToP and CESoPSN pseudowire emulation features. In addition, highly accurate clock recovery mechanisms ensure minimal delay and jitter for transmitting voice, video and mission critical services over packet transport.
The LA-210 can also provide near-fiber access rates of up to 100 Mbps downstream and 50 Mbps upstream over VDSL2 connections.
