Once a dominant global tech company, Nortel is now in the grueling process of liquidating its assets. For example, over the weekend the company conducted an auction to unload its Metro Ethernet Networks (MEN) division.

The winner? It was Ciena (CIEN), which has agreed to shell out $769 million for the asset. The other bidder was Nokia Siemens.

It was a heated auction, as Ciena's original bid was at $521 million.

Late Thursday Sirius XM (NASDAQ: SIRI) disclosed it had received a notice from the Nasdaq stock exchange on Tuesday that its share price has closed below $1 for 30 consecutive days, and is therefore not in compliance with the exchange rules. This means it could possibly be delisted.

Sirius has until March 15, 2010, to regain compliance with the minimum bid price rule, meaning its stock has to close at or above $1 for 10 consecutive business days.

Back in October 2007, Silver Lake and TPG took Avaya private in an $8.2 billion deal. While the transaction involved a good amount of debt, it looks like the company has firepower. That is, Avaya has agreed to pay $900 million for Nortel Network's Enterprise division (the transaction will also involve $15 million in employee retention payments).

The transaction was the result of an auction, which appears to have had some juice. Keep in mind that Avaya's original bid was for $475 million.

Everything was looking up this morning, up until the reaction to companies and their earnings reports. The market felt directionless all day after losing its initial gains despite a new home sales data release that was well above expectations. Ben Bernanke defended his stance on avoiding the next depression. The SEC also issued new short sale abuse guidelines.

Here are today's unofficial closing bell levels:

Dow 9,108.59 +15.35 (0.17%)
S&P 500 982.19 +2.93 (0.30%)
Nasdaq 1,967.89 +1.93 (0.10%)

Top 10 Analyst Upgrades and Downgrades

Rumor has it that Nortel Networks (OTC: NRTLQ) will sell its enterprise division in the near future.

This would be part of a broader plan to break the company apart instead of trying to restructure its way out of bankruptcy. The company is planning to sell its CDMA and LTE wireless businesses to Nokia (NYSE: NOK) for $650 million -- the first unit sale since the January bankruptcy filing.

Motorola (NYSE:MOT) may be the next large American technology company to go into bankruptcy. Telecom equipment maker Nortel, which has several related businesses, filed for Chapter 11 yesterday.

Motorola has two successful divisions. One of these makes home electronic devices including set-top boxes. The other provides telecom infrastructure to large enterprises and governments. Each of them has had positive operating income over the last several quarters.

Motorola's handset division, however, is taking on water quickly. It will cut another 4,000 people this year. It was going to be spun off from the rest of the company, but its sales fell so quickly that the option was killed. Now, a bankruptcy judge may do what the company would not -- liquidate the handset business completely.

Nortel Networks Inc. (NYSE: NT), which has been floundering for years, put itself out of its misery today by filing for Chapter 11 bankruptcy protection.

According to court papers filed in U.S. Bankruptcy Court in Delaware, the Canadian telecom equipment maker owes bondholders $3.8 billion and was facing $107 million in interest payments this week. The company already was facing de-listing from the New York Stock Exchange. It has a $2.4 billion cash position.

Amidst all of the usual hopeful spin in the company's press release was this telling sentence: "The company commenced a process to turn around and transform Nortel in late 2005, and the company made important progress on a number of fronts."

That's right folks, Nortel has been in a turnaround since 2005. Then again, Nortel is not a typical company. Former Chief Executive Michael Dunn, former Chief Financial Officer Douglas Beatty and former Controller Michael Gollolgy are facing charges in Canada for manipulating earnings in the early part of the decade. Shares of Nortel hit $900 on a split-adjusted basis in 2000.

It definitely looks like M&A activity will decline in 2009. What's more, it appears that private financings and public offerings will continue to remain lackluster.

This is bad news for investment banks. However, some of these operators are finding ways to maneuver around by focusing on restructuring work.

Perhaps one of the biggest beneficiaries is Lazard Ltd (NYSE: LAZ).

In fact, this week the firm snagged Timothy R. Pohl, the co-head of restructuring practice at Skadden, Arps, Slate, Meagher & Flom.

Pohl will certainly be busy as Lazard is currently working on the bankruptcies of Lehman Brothers and VeraSun.

This week, Lazard also got several new plumb assignments. The firm is advising Nortel Networks (NYSE: NT) on restructuring options, and other new clients include Tribune and even the United Auto Workers.

Of course, with the protracted credit crunch and the declining global economy, we'll likely see more leveraged companies hitting the wall, providing much more business for Lazard.

In a reorganization of China's telecom industry, which will change the face of the wireless industry, the country plans to merge two of its largest mobile companies, China Netcom (NYSE: CN) and China Unicom (NYSE: CHU). The new firm will be issued on of the three high-speed wireless licenses that the government plans to grant.

China's two largest phone companies, China Mobile (NYSE: CHL) and China Telecom, will receive the other two contracts.

According to Reuters, the 3G development will "unleash billions of dollars in spending for network gearmakers." Those companies would include Nokia (NYSE: NOK), Nortel (NYSE: NT), Ericsson (NASDAQ: ERIC),and Motorola (NYSE: MOT).

The news may also be a benefit to handset makers as they rush to offer products for the new 3G networks. Apple (NASDAQ: AAPL) has still not found a home for the iPhone in China.

More competition among carriers will give it a greater chance to strike a good deal. A new market could also give some aid to Motorola's flagging handset sales and to rivals Samsung and Sony Ericsson.
