Description
The Pushbutton Receiver (PBR) ETU detects and
translates
Telephones, modems, or facsimile machines. This ETU is
required if the four built-in MBD-U10 Unit PBR channels are
not enough to support all the PBR requirements of the
system, or the MBD-U10 Unit PBRs are dedicated to the
VRS(4)-U10 ETU.
