802.3ah Clause 57 (EFM OAM) defines the Operations, Administration, and Maintenance (OAM) sublayer, which is a link level Ethernet OAM that is supported on 7705 SAR Ethernet ports and DSL ports configured as network or access ports. It provides mechanisms for monitoring link operations such as remote fault indication and remote loopback control. EFM OAM is not supported on the 7705 SAR-M GPON module or the 7705 SAR-W Ethernet ports with a GPON SFP installed.
MPR-e radio reset control is provided on the 7705 SAR-8 or 7705 SAR-18. During an MPR-e radio reset, the microwave link is brought down and an upper layer applications action is triggered, such as message rerouting and clock source switching by the System Synchronization Unit (SSU).
Nokia in control of Alcatel-Lucent

The 7705 SAR supports network access control over client devices on an Ethernet network using the IEEE 802.1x standard. 802.1x is a standard for authenticating Ethernet devices before they can access the network. In the case of the 7705 SAR, authentication is performed using Extensible Authentication Protocol (EAP) over LAN (EAPOL).
The 7705 SAR supports port-based network access control for Ethernet ports only. Each Ethernet port can be configured to operate in one of three different modes, controlled by the port-control command:
The 802.1x authentication process is controlled by a number of configurable timers. There are two separate sets, one for the EAPOL message exchange and one for the RADIUS message exchange. Figure 19 shows an example of the timers.
Finland's Nokia said on Monday it has gained control of French rival Alcatel-Lucent following its 15.6-billion-euro ($17 billion) all-share offer and the two telecom equipment makers would combine on January 14.
Western Electric began in 1869 when Elisha Gray and Enos N. Barton started a manufacturing firm based in Cleveland, Ohio, US. By 1880, the company had relocated to Chicago, Illinois, and become the largest electrical manufacturing company in the United States. In 1881, the American Bell Telephone Company, founded by Alexander Graham Bell and forerunner of American Telephone & Telegraph (AT&T), purchased a controlling interest in Western Electric and made it the exclusive developer and manufacturer of equipment for the Bell telephone companies.[8]
His current research activities include Internet of Things topics and the application of SDN/NFV principles to the control and management of connected objects ans services using them in smart environments (homes, offices, buildings, cities...), with an evolution towards self-management of IoT services.
Alcatel-Lucent 3HE02774AB 48 Volt DC Control and Switch Module adds flexible control and manageability to your Alcatel-Lucent 7705 Service Aggregation Router, facilitating synchronization with changing protocols using the Alcatel-Lucent Control and Switch Module. It runs at 48 volts DC.
This is the rare M&A deal that everyone has long-expected to happen and yet seems to please almost nobody. The telecom-equipment sector has been rife with consolidation and restructuring for years, as companies scramble to grab control of technologies that power broadband, wireless networks, networking software and cloud infrastructure.
The world's former top mobile phone maker had gained control of 80% of Alcatel-Lucent's shares by January but has struggled to mop up the remaining shareholders to gain full control of the company.Nokia said today it was settling the ownership issue "through privately negotiated transactions".
In 2013 it bought 50% of its network activities from Germany's Siemens; in 2014 it divested its mobile phone business where it had been the world's number one brand; and in 2015 it sold its mapping unit Here and took control of Alcatel-Lucent.
Provider Edge routers must have a VRF configured for each connected site. VRFs are totally separated in routers control plane by default, so we can depict VRFs as the routers on their own caged in a single hardware unit:
We are done with the configuration, all in all it was not a complex task, what is more important is to understand what's going on with control and data planes. I believe you will like this step-by-step walkthrough via every node in the network.
I will start with dissection of a control plane operation from the point where MP-BGP session between PE routers has been already established and we are enabling VRFs on customers routers. Refer to this overview chart and see how an information about CE1_JUN's loopback interface propagates through the entire network to CE2_JUN counterpart:
To complete this post we should examine the data plane operations. We will see how data packets destined to 1.1.1.1 propagate through the network using the labels allocated during the control plane operations.
This concludes the control and data plane operations walk through. If you followed along the explanations and practiced the configuration steps, you should be in a good shape to implement the basic L3VPN services and also should have a pretty solid understanding of the service establishment mechanics.
It is also utilized for automating the management of new regulations and policies and enhancing the overall organizational efficiency. Additionally, the increasing implementation of machine-to-machine communications is acting as another growth-inducing factor. Service providers are also integrating various value-added services with the software application programming interface (API) for document access controls and policy status reporting. Other factors, including extensive improvements in the IT infrastructure, along with the increasing adoption of subscriber data management solutions, are anticipated to drive the market toward growth 2ff7e9595c
