How DRPD Responds to Calls
When there is an incoming call, the MultiPASS checks the incoming ring pattern and determines the type of pattern being received. The MultiPASS may require up to 10 seconds to determine the pattern type. During this time, any telephone device connected to the MultiPASS reacts according to how you registered the setting.

Communicating Using the Distinctive Ring Pattern Detection (DRPD Feature)
Using the MultiPASS with a DRP service is almost the same as using it with a normal telephone line. When you turn on DRPD, the receive mode defaults to DRPD. When someone calls using the number assigned for telephone communication, the MultiPASS rings in the pattern you registered for telephone calls. When you hear this pattern, simply pick up the telephone connected to the MultiPASS and talk. If you do not pick up the telephone, the MultiPASS continues to ring until the other party hangs up. When someone sends a fax using the number assigned for fax communication, the MultiPASS does not ring. It receives the fax automatically.
