I just read about Motorola's version of the vehicle mounted modem... Click here if you want to read the clip. Basically it covers the details of a vehicle mounted modem and it's ability to handle high bandwidth applications.

Although the article is just a product highlight, I still get excited when I fathom broadband availability in my car, on the train, bus or any other mode of transportation. I am a proponent of Broadband any and every where! Thinking about this product stirred up some consideration for applications that would naturally follow a high speed link into the every day car.

I really look forward to the day we don't have to pay cell phone bills because we no longer have to connect to the telephone exchange to communicate with the masses. If you are like me, you have WiFi at work, at home, at the restaurant, at many public centers, but not in the car... and where would a WiFi phone come in handy? I feel once broad band is common place, IP will push cellular to the way side and allow for unified communications on the go. I also imagine the future of personal transportation when map quest interacts with my GPS to give directions, and Tom Tom will read my Gmail. I will twitter about my traffic frustrations at stop lights (some speech recognition software required). I will be able to access a million internet radio stations on the go, and all this while I simultaneously receive updated coordinates of my daughter’s real time location.

The technology is there, however we still need someone to cover the bill. Lining our high ways and city streets with access points is a huge investment and I don’t think the ROI is there yet. I think for now, products like the Vehicle mounted modem, will be used for very specific applications on private networks. However, in the not so distant future, I think we will see this type of technology start to integrate and become as standard as power windows. What do you think?

If you've been hearing rumors for the past year about SkyPilot - hope you didn't miss the announcement on May 28th that SkyPilot has been acquired by Trilliant Incorporated - self described as the 'leader in delivering Smart Grid solutions that enhance energy efficiency, utility operations and renewal resource integration'.

Spoke with my distribution rep, and they're saying that SkyPilot units will begin shipping in about a month, and if I get any updates on when the products will be moving again, I'll post it.

BTW - the snowglob pix below is one of the best that I've ever seen that describes a product line and what it does...so if you aren't exactly sure what SkyPilot is all about - just check it out.  Also - we developed a few solution pages on SkyPilot some time back - you can still get them here.

I read an Article in our local newspaper a few days ago about counterfeit Cisco. This prompted me to Google (I know it's not really a verb right) the topic and a ton of articles are out there. I read a few and it seems that the two most common ways Cisco gear is counterfeited is a 'look-alike' gimmick. Also, another common way seems to be over production with duplicate serial numbers. I found these articles interesting... and maybe you will too.

Here is a picture of the "Andover Test" that I saw out there, and a few points on how to spot a fraud.

I wrote a post yesterday describing the 1544 that just began shipping last week, and although I won't win a pulitizer prize for writing this piece, I thought I would follow it up with some Adtran 1534 verbiage. There are two skus and of course I followed them with the basics below.

The main difference between the NetVanta 1544 and the 1534 are the number of SFP slots, the later has two and the former has a total of four. Look for a post in the near future with switch comparisons or something along those lines.

SKU                                  List Price
1700590G1 (Standard)       $1695
1700591G1 (PoE)               $2895

          

Here is the link to Adtran's Page for the Netvanta 1534

Take a look at the PDF

There has been some buzz around the Adtran 1544 Gig Switch for the last couple of months, and finally, last week my Adtran rep said they will begin shipping! The 1544 is Adtran's first layer 3 gig switch. It has 28 ports, 24 are copper gig ethernet ports and the other 4 ports are for SFP's. The 1534 did come before the 1544, but it was a layer 2 switch and it only had 2 SFP slots. I copied and pasted some specs for the 1544; and I also threw the general skus down along side the street price. I chose to use the street price because although the list price is useful, the real value of a product is the typical sell price. This product is great, it really can be the backbone of a VOIP network and support the traffic. The price is outstanding, I was looking at other gig switches and it is usually round 4 grand for the higher end gig switches. There are some lower end models that compete with the Adtran's, but the specs nil in comparison to all that the 1544 is capable of.

Features and Benefits

NetLink Technologies now has Nortel Certified Refurbished products.  As many of you know, NetLink has long been focused on being a premier source in the provisioning of new - used - and refurbished products; we are now implementing those same quality standards for the Nortel Certified Refurbished products.

At present, we have not yet loaded all Nortel SKUs into our database for a true eCommerce purchase that many utilize today - but we will get there shortly.  I just wanted to show any and all interested in Nortel refurb, this "Nortel Tested" spreadsheet which shows the Nortel Part Numbers, Quantity, and HECI Code with Description.

All quantities shown on the spreadsheet have been tested as GOOD (see Condition column) and can ship immediately upon purchase.  Remember though, quantities will change daily so be sure to contact myself (Brian) belder@netlinkweb.com or Andrew ahermann@netlinkweb.com to get the latest availability updates.

To all US Veterans out there...Have a great Memorial Weekend!

OK, so the first post I created was about the pieces you need to assemble an MX2800 System.  I realized about halfway through that post that I wanted to include a lot more detail on the specific pieces, so I decided to give the basic assembly info in the first one and then get a bit deeper in this second post.  As noted in the first post, there are three core peices that make up the MX2800.  However, beyond just the current SKUs, there is a little bit of knowledge that comes in handy when buying, selling or implementing a solution.  Let me show you what I'm talking about.

The Chassis 1200290L1

All the part numbers for individual pieces of the MX2800 have changed slightly except for the chassis.  It still has the same part number it was given when the MX2800 was first introduced.  I can't think of any notable changes over the years except for a few screws here and there.  The one really noticeable thing that has been introduced is the fan faceplate.  The chassis ships with a standard faceplate, however if you start stacking multiple units together you do need a fan that can cool the insides down.  The fan faceplate (1202289L1) is a part ordered separate from the chassis.  It is the same as the normal face plate that ships with the chassis except it is modified with a small vent cut out and a fan attached on the inner facing side.  Replacement fans (1200466L1) can be ordered as well.

Controller Cards

The controller cards' current model has two part numbers.  1205288L1 (with modem) and 1205288L2 (without modem).  However there have been several revisions of this controller card.  When I spoke with ADTRAN tech support a while back they said a lot of time the part numbers change due to very minor changes but essentially, all versions of the MX2800 controller work the same way - that is -- they break down a DS3 into 28 T1s like the model before it and the model after it. 

Controller Cards with Modems

• 1205288L1
• 1204288L1
• 1202288L1
• 1200288L1

Controller Cards without Modems

• 1205288L2
• 1204288L2
• 1202288L2
• 1200288L2

Note:  In my experience, very rarely do my customers utilize the modems.  I would say about 98% of my MX2800 customers don't care if there is a modem or not.

Power Supply

The power supply has two generations.  See the part numbers below for AC and DC models.  They both do the exact same thing - provide power to the system.  However, if you use a fan faceplate, you must have a "1202" model.  The "1200" model will not provide the connectors you need to provide power to the fan faceplate.

AC Power Supply

• 1200289L1
• 1202289L1

DC Power Supply

• 1200289L2
• 1202289L2

The MX2800 is probably one of ADTRAN's hottest products.  I'm basing that statement on the sheer number of requests that I get for it day in and day out.   This may be redundant for anybody familiar with the ADTRAN line - but for those of you that don't know, this post could have some valuable info for you.

The MX2800 is made up of only three core pieces; unless you make the unit redundant - then it would have five pieces (see below).

Non-Redundant	Redundant
Chassis 1200290L1  (Plus)	Chassis 1200290L1  (Plus)
Controller Card 1205288L1*  (Plus)	Controller Card 1205288L1 Controller Card 1205288L1  (Plus)
Power Supply 120289L1** (Equals)	Power Supply 120289L1 Power Supply 120289L1 (Equals)
4205290L1 Non-redundant Bundled System	4205290L2 Redundant Bundled System

*There are two options for controller cards - "with modem" (1205288L1) and "without modem" (1205288L2).  The modem provides a dial up feature for configuration and trouble shooting.

**The Power Supply naturally has two flavors: AC Power (1202289L1) and DC Power (1202289L2).

The chassis just provides the housing for the components.  It is a passive device that provides the interfaces.  On the back, it has two BNC or Coax connections (both have a send and receive).  It also has an Amphenol connection (send and receive).  Please keep in mind that the 2800 only handles one DS3 and the second interface and controller are only for redundancy failover.  The same holds true for the power supply.  Although both are connected simultaneously, only one is powering the device while the other one is for backup.

The Controller is the brains of the outfit.  It takes the channelized DS3 that comes in from the BNC connectors and breaks it down into 28T1s and then sends them out the Amphenol connection.  The Amphenol connection is cabled to a Patch Panel (1200291L1) that gives 28 T1 RJ48 ports.  See the diagram below.

P.S.
I'm thinking I want to give a bit more info on the different generations of power supplies and controllers so be on the look out for part two of this...

After searching the ADTRAN website and flipping through the catalog, I realized there was no listing for a redundant power supply for the MX2820.  After doing a little research, I found that there was no power supply - period.

This is because it connects directly to DC power and the chassis handles that.  As far as battery back up, there isn't a designated bundled part number, but I did discover if you took the bundle for the Total Access 750 and 850 (which is the same battery back up as for the MX2800) you can create the parts necessary to provide battery backup for the MX2820.

Check out my diagram below - it's the one for the MX2800 and TA units, but it will give you an idea of what I'm talking about.  Below the diagram are the part numbers needed for the bundles.

Here's the part numbers for the MX2800 and the Total Access 750 and 850 Batter Back Up Unit: 

• 4175043L2 Bundle P/N
• 1175044L1 Battery
• 1175043L3 AC Supply and Battery Charger
• 1200657L2 Power/Alarm Cable

There is no bundle for the MX2820 battery back up system, but here are the parts you need to make one...

• 1175044L1 Battery is the same as the other bundle
• 1175043L3 AC Supply and Battery Charger is the same as well 
• 1200657L10  POWER SUPPLY TO 3 LUG CABLE is needed because the connector on the back of the MX2820 is different.  The MX2820 looks like a typical DC unit that you have to screw down, the other version for the TA units and the MX2800 has a 4 box molex connection.
