Class A common stock offered to holders of warrants. Plan of Distribution. An investment in our Class A common stock is risky. The risks and uncertainties described in our SEC filings are not the only ones facing us.

Additional risks and uncertainties not presently known to us, or that we currently see as immaterial, may also harm our business. If any of the risks or uncertainties described in the applicable prospectus supplement or our SEC filings or any such additional risks and uncertainties actually occur, our business, results of operations, cash flows and financial condition could be materially and adversely affected.

In that case, the trading price of our common stock could decline, and you might lose all or part of your investment. However, all the warrants covered by the registration statement of which this prospectus is a part have a cashless exercise provision that allows the holder to receive a reduced number of shares of our common stock, without paying the exercise price in cash. To the extent any of the warrants are exercised in this manner, we will not receive any additional proceeds from such exercise.

We have not paid cash dividends on our common stock and do not intend to pay cash dividends in the foreseeable future. We intend to retain any earnings for use in our business. We also may enter into other credit facilities or debt financing arrangements that further limit our ability to pay dividends or make other distributions.

We are offering shares of Class A common stock upon the exercise of certain warrants originally issued by Stratex and assumed by us pursuant to the warrant assumption agreement. We assumed these warrants in connection with our acquisition of Stratex in January pursuant to the terms of the combination agreement.

Accordingly, while the increase in our net tangible book value to our existing stockholders from the exercise of the warrants in the offering would be minimal, there would be an immediate substantial dilution in the net tangible book value to the purchasers of shares of Class A common stock sold in this offering.

This prospectus relates to the issuance of , shares of Class A common stock upon the exercise of warrants. The following is a description of the material terms of our warrants and is qualified in its entirety by reference to the full text of the warrants and the warrant assumption agreement, included as an exhibit to the registration statement of which this prospectus is a part. Of course, the main unit 10 may periodically monitor such information at predefined time intervals e. Additionally, the main unit 10 may request such information from the element 40 at predefined time intervals e.

Upon receiving an alarm or other indication from the element 40 , the main unit 10 may initiate a calibration of the local clock 50 by providing a command to the element's respective calibration unit 54 via a command unit 16 , or the main unit 10 may remotely calibrate the local clock 50 by controlling the tuning voltage of the local clock Of course, calibration of the local clock 50 may be automatic without any personnel intervention. The main unit 10 , in accordance with embodiments of the present subject matter, may further include a transceiver unit 12 adapted to transmit calibration information provided by the command unit 16 to calibrate the local clock 50 and adapted to receive information from the element To ensure that there are no interruptions to active radio traffic, the element or receiver is maintained in a known, coherent state throughout the calibration process.

For example, responsive to data provided by the command unit 16 , the local clock 50 into a calibration mode to tune the frequency thereof to the network reference. TO ensure that there are no interruptions to radio traffic, phase transitions of the local clock are conducted as slow as necessary such that the mixer of the element or receiver is synchronized in frequency and phase with each phase transition during the calibration process. Thus, the element continues communication with another element s or the remote location during the calibration process.

The calibration unit 54 may be adapted to calibrate the local clock 50 with the aid of calibration information provided by the main unit Such calibration information may comprise a request or command from the main unit 10 whereby the calibration unit 54 enters into a calibration mode.

In a calibration mode, the local clock 50 may determine or calculate a frequency offset between the reference clock 15 and the local clock 50 and adjust the tuning voltage of the local clock 50 to have a lowest tunable offset.

The information may also comprise data from the main unit 10 that directly adjusts the tuning voltage of the local clock The calibrating unit 54 may also be adaptable to utilize a mathematical method for clock calibration, where variations in frequency offset of the local clock 50 may be used in the calibration thereof.

For example, the calibrating unit 54 may determine an average of frequency offsets as measured by the main unit 10 over a predefined interval.

The average constitutes the difference between the predefined, and therewith expected, frequency and the actual frequency. For example, the main unit 10 may sum n offsets and divide the sum by n. The main unit 10 may then compare the sum divided by n to a predetermined threshold and calibrate the local clock 50 as a function thereof.

Of course, the element 40 or local clock 50 may be adaptable to measure, determine, and provide this information to the main unit Thus, such a mathematical method may moderate unnecessary alarms or calibration requests or commands due to noise and spurious signals. Embodiments of the present subject matter are applicable in networks and systems utilizing synchronous communication protocols such as Synchronous Optical Network SONET , Synchronous Digital Hierarchy SDH , T-carrier hierarchies, and E-carrier hierarchies, as well as in other known synchronous communication protocols.

The aforementioned communications protocols are exemplary only and are not intended to limit the scope of the claims appended herewith. It is an aspect of the present subject matter to drive value in a radio communication system. For example, users of embodiments according to the present subject matter may issue maintenance procedures from a centralized location such as a Network Operations Center instead of sending technicians to each site thereby saving labor and associated costs.

In another aspect of the present subject matter having installations without a network reference clock, it is possible to perform a remote calibration or tuning command by injecting a reference clock on a data carrying tributary at a distribution site and claiming it as the calibration reference. Thus, embodiments of the present subject matter may be applied to network installations employing an asynchronous communication protocol.

In an additional aspect of the present subject matter, radio communication between a radio undergoing calibration and other radios in the communication network continues during calibration. In an alternative embodiment, radio communication between the radio undergoing calibration and the main unit having the network reference clock may also continue during calibration.

It is a further aspect of the present subject matter to incorporate a network timing solution with a local RF timing solution within the context of the radio unit. An exemplary method for calibrating a local radio reference clock for a radio operating in a radio network according to an embodiment of the present subject matter determines at the radio an offset between the local clock and a network reference clock, places the local clock in calibration mode, and calibrates the local clock using a radio link to reduce the offset.

Information representative of the offset may be transmitted from the radio to a remote location whereby the remote location may place the local clock in the calibration mode. The offset may be determined as a function of measurements taken by the network reference. The network reference clock may utilize a synchronous communication protocol or in an alternative embodiment, the network reference clock may be replaced by a network reference clock signal injected into a data-carrying communication channel to thereby communicate using an asynchronous communication protocol.

Another exemplary method of calibrating a local radio reference clock for a radio operating in a radio network according to an embodiment of the present subject matter calibrates the local radio clock with a network reference clock by communicating information to the radio over a radio communication channel using a synchronous communication protocol. The information transmitted from the radio may be representative of an offset between the local radio reference clock and the network reference clock.

Accordingly, a remote location may place the local clock in a calibration mode as a function of the information. As shown by the various configurations and embodiments illustrated in the Figures, a system and method for remote monitoring and calibration of a system reference clock utilizing a network timing reference have been described.

While preferred embodiments of the present subject matter have been described, it is to be understood that the embodiments described are illustrative only and that the scope of the invention is to be defined solely by the appended claims when accorded a full range of equivalence, many variations and modifications naturally occurring to those of skill in the art from a perusal hereof. A method of calibrating a local radio reference clock for a radio operating in a radio network, the radio network having a main unit with a network reference clock, comprising the steps of: determining an alarm condition triggered when a frequency of the local radio reference clock is different from a predetermined setpoint by more than a prescribed amount;.
