MODEM PBA
The MODEM PBA is optionally installed on the DP120F, and is standard on the DP125F.
The MODEM PBA consists of the modem (IC1) with a transmission speed of 33.6kbps and
other peripheral devices. The MODEM PBA is used as a MODEM for Line 2.
When the IOCS8X signal output from the DMAC GA (IC16) on the Main PBA is at LOW level,
the MODEM PBA will be selected to perform facsimile communication by Line 2.
