Force 10(G) Infinera
Taking this opportunity, I caught up with Singh, who is the president and the CEO of Infinera. "It has been the inverse of the perfect storm for us," he says. While rest of the industry was shrinking and cutting back its investments in DWDM-related research, Infinera was boosting its spending. Now with carriers opening their wallets, and demand for bandwidth rising due to increased sales of broadband connections and other IP-related services, Infinera finds itself in an enviable position of being at the right place at the right time with the right technology.

PodSnacks: SONET
At the core of virtually every carrier and MSO's data and voice network sits a technology we have been using since 1984. By some estimates, over 99% of all of the voice and data traffic that touches a carrier or MSO network crosses a SONET facility before it finishes its journey. In today's PodSnack, Michel explains SONET to you.

A Transport Engineer has responsibilities for decisions regarding interconnections in his or her markets. They are responsible for decisions regarding current and future facility connectivity. The studies performed by the Transport Engineer support the decisions made on the method of transport, selection of a provider, least cost routing, budget considerations, sizing of the transport medium, diversity considerations, vendor contractual benefits, as well as capacity availability and timing issues. The Engineer is responsible to fully analyze alternative means of transport such as microwave, dark fiber, or ATM, obtain quotes from vendors, and perform a total cost analysis. Transport Engineers interface with multiple providers to resolve chronic trouble areas and improve down time on the network. Transport Engineers direct the Facility Engineers when, where and how to order all needed facilities. This includes monitoring capacities and issuing orders for new projects to augment existing quantities. These items include those such as Digital Cross Connect Systems, multiplexers, DSXs, microwave radios, and all ancillary equipment. Transport Engineers attend special project meetings, and participate on many conference calls pertaining to all projects, which require connectivity via facilities. They help provide current status of new circuits, changes in their projects, and track progress of OCN service implementation. The Engineer designs the plans for new SONET network solutions for their markets and interfaces with the LECs to construct those services. A major function for the Transport Engineer is the responsibility of management of Capital and Expense budgets for their markets. They solicit data from Interconnect/Traffic Engineering, RF Engineering, and the Forecasting group to build, track and maintain their piece of the budgets for Finance.

SONET over SDH
Had an interesting circuit last night. It was an OC3. They had it designed over two SM04 SDH facilities on each side of a Ciena Core director. We had to provision the to iMTN BBDCS on either side of the Ciena ring to convert the SONET to SDH and back to SONET again. I wasn't aware how they could do that or that it could even be done until I worked that circuit. Always something new to learn in telecommunications.

Hotcut Frame Relay To IP
I joined a bridge for customer hotcut. Customer is cutting from frame relay DS3 service to IP DS3 service. Customer will move to new router at customer premise. I unmapped NEC 2400 STS1 across SONET ring and remapped STS1 across same SONET ring now going to new router on our end replacing old frame relay switch.
The new portion of the circuit path had not been pre-tested and the new circuit was not coming up. We discovered that the new circuit path had been provisioned to the wrong router on our end. I had provisioning join the bridge and redraw the equipment path drawing to the correct router. I then called the switch site and had them rewire the new path to the correct router. Circuit came up on new routers at that time.

Framing Format: C-bit vs. M13
Today a customer called in and had a WBDCS ds3 circuit. I see the circuit is down. He says he wants C-bit Parity. I say it should be M13 because it's channelized for 28 T1's. He changes his end to M13 and I say see there you fixed it. He says he has another circuit and it is C-bit Parity and he wants C-bit Parity on this one. I check his other circuit and sure enough it's set for C-bit Parity. So we change both ends to C-bit Parity and it comes up and he says he's happy and that's how he wants to leave it and use it like that. So I had always thought if you had a ds3 with a WBDCS on it and it was channelized for 28 T1's you had to have M13. I'll have to talk with the guys at work about this one.
And I think I figured out why Larry doesn't like to use the SMS GUI for WBDCS work and instead prefers to use the QuickPad cut-through. Because the SMS WBDCS GUI doesn't work for sh*t.

Switched Ethernet
Switched ethernet is a packet-switching technology that dramatically reduces the network congestion caused by using the CSMA/CD medium access control over shared media. Sometimes known as a switched hub, a switch offers guaranteed bandwidth per port and operates at the medium access control sublayer of the network access layer of the TCP/IP protocol suite.

In it for the long haul: Optical transport systems go the distance
A change is brewing for long-haul networks. Companies such as Qtera and Corvis are developing ultra long-haul optical transport systems that can send traffic as far as 3200 to 5000 kilometers without electrical regeneration. These systems could encourage carriers to rethink their network architecture.

VOIP vs PSTN
It's no secret that carriers are looking to move from traditional, circuit-switched voice to voice-over-packet technologies. In a way, of course, they have already done this years ago with Asynchronous Transfer Mode (ATM), but ATM's fixed-length micropackets (cells) and connection orientation were adopted specifically to be voice-friendly. What's new is the wholesale move to the variable length and connectionless orientation of Internet Protocol (IP) packets, which are definitely not the obvious architecture of choice for voice.

ENUM could be the missing link to next-generation voice services. But will it be hindered by a group of telecom incumbents?
Technology defines tomorrow's telephone network. Whether it's the newest whiz-bang handsets, crackerjack protocols, or light-inspired optical gizmos, high technology will make or break the next-generation phone network. Right?
Think again. The battle for the new phone network is gearing up in the political back alleys of Washington, D.C., where incumbent providers and upstart telephony competitors are battling over the deployment of RFC 2916. This new Internet protocol, dubbed ENUM (short for Electronic Numbering), maps phone numbers to URLs, and it could give Internet telephony providers the technology to turn the Internet into a fully functional telephony network.

Physical Layer
The OSI, or Open System Interconnection, model defines a networking framework for implementing protocols in seven layers. Control is passed from one layer to the next, starting at the application layer in one station, proceeding to the bottom layer, over the channel to the next station and back up the hierarchy.
Layer 1 of the OSI model is the Physical Layer.
The Controller Area Network (CAN) protocol defines the data link layer and part of the physical layer in the OSI model, which consists of seven layers. The International Standards Organization (ISO) defined a standard, which incorporates the CAN specifications as well as a part of physical layer: the physical signaling, which comprises bit encoding and decoding (Non-Return-to-Zero, NRZ) as well as bit timing and synchronization.
