The Electra Elite 192 system has four built-in Push Button
Receiver (PBR) circuits on the CPUB( )-U10 ETU. The
PBR circuit detects and translates DTMF tones generated
by Single Line Telephones, facsimile machines, modems,
or analog voice mail ports. Incoming DTMF signals can
also be detected from a CO trunk using the DISA feature.
The system Auto Attendant feature and DISA feature
must use the CPUB( )-U10 ETU PBR circuits.
An optional PBR( )-U10 ETU that provides an additional
four circuits can be installed. The number of PBR( )-U10
ETUs needed depends on the number of Single Line

voice mail ports needed. Automated Attendant and DISA
trunks connected to the system must also be considered.
When the optional PBR( )-U10 ETU is installed, these
PBR circuits can be used only. for SLI ports connected to
the system.
