Network profiles 
The networks in use in different countries each have a different list of 
channels and system parameters required for access to that network.  
These parameters must be configured in the modem.  The Boomer II 
modem is able to store these parameters for up to 10 networks, and 
through NCL commands, the user can choose between them so that the 
correct parameters are used for the user’s current location.   The 
parameters relating to a particular network form what we call a profile.  
The Boomer II modem is supplied to customers with between 1 and 10 
of these profiles, depending on the international roaming needs of the 
customer.  The default profile will also be set according to the 
customer’s requirements, but is traditionally set to the correct 
parameters for use on the USA’s Motient network.  For details on the 
NCL commands to view the profile list, and set the currently active 
profile, please see the WN_PROFILE  setting under Appendix A. 
RD-LAP Network Operation 
The RD-LAP 9600 and 19200 protocols are used by DataTAC 4000 
and 5000 networks. The modem supports both continuously keyed, 
multiple channel (MFR) and intermittently keyed, SFR (single 
frequency reuse) network configurations, depending on the network 
type. The RD-LAP protocol specifications provide the reference RF 
protocol link-access procedures supported by the wireless modem. 
While on the network, the modem performs auto-roaming and battery-
save (Power Save protocol) functions. 
MDC 4800 Network Operation 
The MDC 4800 protocol is available exclusively on Motient (United 
States) and Bell Mobility (Canada) networks. The modem supports 
intermittently keyed, SFR network operation. 
 
NoteOn Motient and Bell Mobility networks the modem operates in 
either MDC 4800 mode or RD-LAP 19200 mode, as provided by local 
coverage, however, it is recommended contact be made with the 
relevant network operators to confirm specific details.
