                -------------------------------------------------
                
                Represented as 32-bit float numbered from 0 to 31, left to right. 
                The first bit is the sign bit, S, the next eight bits are exponent 
                bits, E, and the final 23 bits are the fraction F:

                The value V represented by the word may be determined as follows:
                
                     If E=255 and F is nonzero, then V=NaN (Not a number) 
                     If E=255 and F is zero and S is 1, then V=-Infinity 
                     If E=255 and F is zero and S is 0, then V=Infinity 
                     If 0<E<255 then V=(-1)**S * 2 ** (E-127) * (1.F) where 1.F 
                is intended to represent the binary number created by 
                prefixing F with an implicit leading 1 and a binary point. 
                     If E=0 and F is nonzero, then V=(-1)**S * 2 ** (-126) * (0.F) 
                These are unnormalized values.

                ----------------------------------------------
                Each SkyZhone45 pair is comprised 
                of an A type ODU, which transmits at frequencies
                5735Mhz through 5815Mhz, and a B type ODU,
                which transmits at frequencies 5260Mhz through 5340Mhz.
                Mapping from channel to exact frequency is shown below.
                
                Channel A's receive channel is Channel B's transmit frequency.
                Channel B's recieve channel is Channel A's transmit frequency.
                
                There are 17 available channels for the A type transmitter and 17 channels 
                for the B type transmitter.
                
                
                The following rules apply:  
                Primary and secondary frequencies may NOT use the same channel.
                
                Channels are assigned in fixed pairs.  There are only 17 total possible
                permutations of frequency assignments for the primary or secondary channel.

                SinglePrecisionFloatingPoint representation of radio operating frequency.
                
                Channel numbers cannot be entered directly for the 23GHz family.
                Instead, the interface expects frequencies to be entered.
                The 23Ghz band (used by SkyZhone 155 and 8) does not adapt well 
                to general channel numbers.  UK has a channel plan, Germany a different 
                one, France a different one, Mexico a different one, etc.
                Channel 1, for example, means a different frequency in each plan.  
                There is no global reference, and we don't want to have to change 
                software everytime a new channel plan comes in from a new customer.  
                So we will let them Tx frequencies (in MHz) directly. 
                The Rx frequency is not written by the user, but is calculated using
                the entered Tx frequency and the channel separation.  Basically channel
                separation is how far apart the tx and rx are spaced.  Every coutnry 
                we know of uses one of 3 channel separations.   
                The rx frequency is just the sum or difference of the tx freq and the 
                separation (depending on whether you are the A or B side of the link). 
                
                It is certainly possible that ZMS or any other NMS could provide an 
                interface which allows users to select a channel according to the local
                channel plan of the unit and convert it to a frequency.  If this is desired,
                a mapping of channel to frequency is needed for the site, and as mentioned
                already, this depends upon the prevailing channel plan of the country
                where the unit is installed.
                
                Some channel plans are linear - that is calculable and evenly spaced.
                Others (e.g., French) are not linear, and so each channel to frequency 
                association would be a unique vector in a table.
                
                Also note that only 3.5MHz wide channel spacings and their multiples
                (7Mhz, 14Mhz, 28MHz) are supported at this time.  This rules out the North
                American 23GHz band (which uses 2.5MHz spacings).

                have been SinglePrecisionFloatingPoint rather than Integer32, if
                the Pahrser (internal Zhone tool) would have been smart enough 
                to use it.

            DESCRIPTION
                "Textual method to enter and display floating point numbers.
                Actually three different formats are acceptable:
                
                 
                   [+/-]WXYZ    -  where WXYZ is a 1 to 15 digit number
                   [+/-]WXYZ.0  -  where WXYZ is a 1 to 15 digit number
                   [+/-]W.XYZ [+/-]Ejk  
                                -  where W.XYZ is a 1 to 15 digit floating point number
                                and jk is an integer.  
                                White space between elements is OK.
                
                For example, the number 1324.0 can be represented as:
                        1234
                        1234.0
                        1.234E4
                        1.234 E4
                
                A radio frequency of 23.456Ghz, for example, may be represented as
                
                        23.456 E9
                        23456  E6
                        23456000 E3
                        23456000000
                        23456000000.0
                        
                A BER threshold of 2.5 errors per 10,000 bits can be represented as 
                
                        2.5 E-4
                        2.5E-4
                        2.5 E -4           "
