2A.7 Receiving Dolby Fax Calls

Call setup is automatic: The ISDN unit will automatically answer an incoming call,

and the DP524 decoder unit will automatically configure itself for the proper

algorithm.

But, your DP503 encoder must be manually set to match the incoming call:

1. With the DP503 in the default encoder parameters screen, make

adjustments to the encoder, if necessary, to match the incoming algorithm,

data rate, channel mode, sample rate, and aux rate.

Note:Refer to Section 5.2 for a comprehensive procedure on changing encoder parameters.
