2.048Mbps Wireless Modem 

 

The following is a description of the possible configurations when connecting V.35/RS-
530/X.21 end equipment to the 2.048Mbps Wireless Modem. The configurations described 
are applicable to software version 1.5 and up with a V.35/RS-530/X.21 LIU equipped with 
jumpers for setting the mode of operation. 

 
These standards define the operation of a communications channel, consisting of end 
equipment units connected to the communications channel by a modem. The standards define 
DATA circuits and LOCK circuits to time them. 
 
The end equipment is normally called DTE and the modem is normally called DCE. A DTE 
connects to a DCE. DTE or DCE assignments define the direction of the DATA, CLOCK, 
and CONTROL circuits supported by the standard. 

 
Table 1 describes the possible configurations: 

The 2.048 Mbps Wireless modem can be configured either as a DTE or as a DCE. The 
configuration is set by jumpers on the LIU board and through theRS-232 monitor.  
 
It is important to note that modem assumes that the clock frequency on both sides of the link 
is exactly the same, therefore the clock frequency can be forced on the Master side of the link 
only.  
 
Possible configurations are described in Table A-2.
