Alcatel 1680 OGX
Worked on OC12 transversing Alcatel 1680 OGX. Customer ordered telco on both drops. Two passthrough nodes on the ring. Customer Cisco router at drop 1 can see soft loop on STS12C at handoff to drop 2 telco. Customer Cisco router at drop 2 can see soft loop on STS12C at same drop 2 handoff address. Drop 2 Cisco router cannot see soft loop on STS12C at first passthrough noded beyond handoff location. Seeing "Incoming Fade" alarm on OC12 at handoff point. Will dispatch fiber tech to handoff point firt thing in the morning.

Ciena K2
Industry sources have long said the K2 wasn't in working order when Ciena bought it and that the company has had to work long and hard to get it out the door. Others say it's still a dud. The latest rumor? Ciena may kill development of the K2 altogether.

Worked with customer to install OC3 circuit transversing Ciena K2 and Sycamore 16000. Found circuit not mapped on OC48 in the Alcatel 1680 ring between the two network elements.

Mapped DS3 Circuit
I just finished mapping a DS3 circuit between Dallas, Texas and Witchita Falls, Texas. The network elements consisted of one Cisco 15454, three Alcatel 1648 rings, one Tellabs 6500 BBDCS, and one iMTN BBDCS. The circuit was mapped STS1. There was on dsx3 electrical breakout crossconnect at the midway point central office. Telco carrier provided last mile at both ends to customer premise. Will use Adtech test set mapped in at iMTN BBDCS to test circuit to customer premise in both directions at this time.

StrataLight Powers Cisco's OC768
In this 'fastest IP network' demonstration, two of Cisco's new CRS-1 core routers were located within MCI Points of Presence in San Francisco and San Jose, California. The routers, both equipped with short-reach 40-Gbps OC-768c optical client interfaces, were interconnected over MCI fiber facilities using StrataLight OTS-4000 Optical Terminal Subsystems in conjunction with Cisco ONS 15454 SONET MultiService Transport Platforms, which provided optical amplification.

Cisco's CRS-1 Goes Optical
Cisco's principal announcement for the CRS-1 concerns a pair of cards with high-speed DWDM optics. This opens the possibility of the box launching IP traffic onto DWDM wavelengths directly, bypassing the Sonet layer.

Discussing telecom industry with co-workers. Talking about the new at&t, Verizon, and Sprint/Nextel. Wondering what will become of Bell South, Qwest, and Cincinatti Bell.

Worked with customer and telco to install OC3 circuit from Ohio to Florida. Mapped Adtech test set into Tellabs 6500 BBDCS at midway point in Nashville, Tennessee. Tested circuit good both ways to hard fiber loops at customer premise demarcs in Florida and Ohio. Pulled test set out and normalled circuit at Nashville. Customer Cisco routers plugged into circuit at both ends. Routers came up with 100% good extended ping at this time.
