TMCnet Goes Twitter

July 4, 2007

It seems like if you are under 18 you spend a good deal of time twittering on well – Twitter. Since my typical reader is above 18 you may not be aware that Twitter is a service allowing you to send and receive messages via SMS on cell phones. People spend hours letting their friends know (in excruciating detail sometimes) about all aspects of their life. “I am going to have lunch.” “I am having a snack.” “I am sick,” are some of the things you may see while twittering.   But if you get sick of twittering with friends and are interested in using Twitter to keep up with the latest (and best of course) communications and technology news and analysis, be sure to check twitter.com/tmcnet.

iPhone Problems

July 2, 2007

  For the record, I do not have an iPhone. I may be the only techie who doesn’t have one at this point. I didn’t stand in line for hours or camp on a sidewalk waiting for this device to arrive.   However, I just spoke with Michael Khalilian of the IMS Forum and I apparently was the first caller on his new iPhone. He was telling me the level of complexity to get the device working is incredible.

Nokia N800 and Free WiFi

June 26, 2007

The Nokia N800 tablet is an exciting example of what communications technology can and should be. I was sent one from the company to try and to be honest I didn’t expect to be impressed. When I started using it I was blown away at the fact the device is about the size of my smartphone yet is about as powerful as my laptop. The screen is 640x480 and you appreciate the ability to read full web pages at this resolution.   Unlike my laptop it actually has better speakers and surprisingly can stream audio, video, play Flash (including YouTube) and even videoconference via its embedded camera which can rotate.

Where Did Rich Go?

June 25, 2007

OK, Rich has not abandoned his loyal readers. He really values these people as without his readers he would stop blogging and at that point he would have to find a hobby or two. Thankfully, dear readers, I am still with you and in fact this week my family decided I work hard enough to take some time off.   So I am at an undisclosed location which has plenty of sand and beach chairs. This doesn’t explain how I got locked in my hotel room by myself however.

Cox Selects BroadWorks VoIP

Clarus Systems

June 20, 2007

Clarus Systems Enables VoIP Rollouts to go More Smoothly and keeps things Running that way   As telephony transitions to corporate WANs and LANs the issue of ensuring telephone systems continue to function regardless of network problems becomes an important issue. In some corporations there is a belief that the users are there to tell tech support when there are problems with the phone system.   In fact this may be OK if telephones are not mission critical or you have a small number of phones in your organization. But in either of these cases it pays to be proactive in determining of your VoIP solution is functioning correctly in your organization.   In a recent conversation with Clarus Systems, company executives explained to me how their VoIP testing products are doing quite well in the market and especially Fortune-class financial companies.   One area the company has been successful at is deploying branch office VoIP solutions with high levels of certainty the solutions will work in each branch. One Clarus Systems customer in fact is now able to turn up 15 branches per week as a result of working with the company.   Gurmeet Lamba VP of Engineering at the company explained to me how VoIP systems change constantly as new firmware is updated on phones and patches are added to servers.   Some real world problems the company has identified is a case where a company forgot to upgrade their UPS system and as a result if a power outage had taken place a large bank of phones would have been out of service.

Cisco’s Chambers on Telecom Phase II

June 19, 2007

As I sit in a press room in Chicago eagerly awaiting John Chamber’s entrance, about 60 or so members of the media are catching up on gossip and the happenings in the industry. Cisco’s Jeff Spagnola Vice President, Worldwide Service Provider Marketing kicked off the press conference and made a reference to Castaway, the movie with Tom Hanks. He discussed the end of the movie where Hanks had to choose from 4 different roads. He mentioned this crossroads is exactly what the service provider industry is dealing with today.   Jeff mentioned many carriers are on the way to a next generation IP infrastructure and the choices these providers make are complicated.

John Chambers

June 19, 2007

John Chambers the CEO of Cisco is getting ready to speak here in Chicago and John is generally one of the more dynamic speakers the industry has. Surprisingly, I haven’t heard John speak as often as I like as I seem to always have a scheduling conflict. at events he speaks at. I heard a bit of his talk at Interop and it was great. Today, I am not sure what to expect but think telepresence will be part of the message.

Packet Island

June 19, 2007

Packet Island Redefine Network Management   “It is not just about kbps” is the statement ringing in my head after a discussion I had at TMC’s Communications Developer Conference in Santa Clara, CA last month with Praveen Kumar the co-founder and president of Packet Island. As Praveen pointed out, a network can become flooded with packets when VoIP is deployed. In some cases, packet volumes can increase by a factor of ten or more.   To help companies cope with the ever-increasing number of packets on a network the company makes an appliance which can sit in front of the PBX and monitor quality metrics. For those of you interested in the open-source world, the company also makes a software agent for Asterisk.
