Connecting an external music source

Use this procedure to connect an external music source to the BCM system. You can use any
customer-supplied, approved, low power device as a music source. A music source includes
equipment such as a radio with a high-impedance earphone jack.

Music-on-hold specifications

Ensure that the music source follows these guidelines:
• Nominal input impedance is 3.3 kilohms.
• Nominal sensitivity of this interface returned to digital encoded PCM is
-22 dBm0 for a 0.25 V rms input signal.
• The input is limited so that the encoded analog content at the digital interface to the network
does not exceed -12 dBm when averaged over any 3-second interval.
• The maximum non-clipped input level is 1 V rms.
• The interface is protected against ringing cross.
