Kent, Bell labs has a ton of them, obviously going forward we will see collisions in high tech especially in the communications field. Cisco does a lot of patent research but there will still be head-ons going forward. A lot of Bell labs research in the optical fields were done years ago and at that time there was not a need to implement them (no markets!). The attorneys will just love this, it will never end! Still very bullish Cisco for the long run. regards Eric

Cisco's 2600 Router Says It All With Voice Over IP By Mike Fratto ÿ Talking on the phone is the next best thing to being there, or so AT&T wants us to believe. Unfortunately, almost being there can be quite costly. Cisco Systems' 2600 Series Modular Access Router takes you where you want to be using VOIP (voice over IP) over your existing WAN connection or IP network. This product isn't a dedicated VOIP device, but a full-fledged router that uses the same hardware modules for media access as the Cisco 3600 router family. I tested a beta version of the 2611 in our Syracuse University Real-World Labr and walked away whistling a happy tune. The 2600 is targeted for the branch office, and its modular design lets you build in the functionality you need while leveraging your equipment investment. As your needs change, you can swap out modules as necessary and reuse them in either the 1600 or 3600 series routers. VOIP is relatively new to the enterprise networking arena. Although you probably won't want to change your voice network tomorrow, VOIP lets you leverage the Internet or your internal IP network for voice and data. Besides routing calls over IP, you can connect to the PSTN (public switched telephone network) with a VIC (voice interface card), to a PBX with a WIC (WAN interface card) or to an ISP via PPP over ISDN. These options depend on where you route your calls. If your network is running a routing protocol such as RIP or OSPF, the 2600 will automatically find the best route to the destination in the event of a network failure. Music to Our Ears I initially set up the 2600 and the 3600 for VOIP over Ethernet. Both routers were equipped with Cisco VIC-2FXO and VIC-2FXS modules that include RJ-11 telephone jacks and receive and send a dial tone, respectively. Next, I plugged the phone line from the PSTN into the FXO and the phone into the FXS. On the command line, I entered the appropriate telephone number, and the 2600 made a VOIP connection to the destination router, which rang the phone. I used a four-digit extension for our testing, but I could have used any number of digits. During testing, I made a VOIP call that was routed to the PSTN over a telephone line. In our lab, I must dial an access prefix to tell the Centrex telephone service whether the call is on- or off-campus. I have to prefix the call with a digit that tells the destination 2600 to send the call over the telephone line, which complicates the dialing process. You can make this a seamless procedure by having the 2600 prefix access digits to the phone number. During testing, I dialed a 9 for off-campus dialing, so I set the 2600 to grab a telephone line when it saw a 1-315 dial string. It prefixed a 9 to make the number 9-1-315-555-1212. Users can pick up any phone in the office and dial without having to change their behavior. Configuring the 2600 for voice calls can be a daunting task because you need to configure the lines (interfaces), attach phone numbers to the interfaces and configure number expansion on the command line. Cisco's ConfigMaker eases this burden. I tested an alpha version of ConfigMaker 2.1 that incorporated the 2600. With a few mouse clicks, ConfigMaker completely configured the 2600 and generated a configuration file for it. I cut and pasted the resulting configuration file into the 2600. The final version of ConfigMaker will be able to push the configuration out over the network. If you're familiar with Cisco's IOS (Internetwork Operating System) and architecture, ConfigMaker simplifies installation and configuration. If you are not familiar with IOS, ConfigMaker is a decent aid for learning IOS configuration commands. Mike Fratto can be reached at mfratto@nwc.com.
