Note: During initial unit registration the set information in the modem is propa-

gated to the VMS database which fills in the Home State values.

The In Band tab also identifies the switching Modulator (the remote data

modulator) for the subnet, Downlink Modulator is the hub forwarding

(outbound) TDM modulator to remote (used for Roaming applications) and the

Uplink Demodulator is the Home State hub demodulator (typically is the

STDMA demodulator). These associated devices set the known states for recov-

ering remote data units.

Clicking the Select button brings up the Select Modem dialog shown in

figure 5-51.
