Music-on-hold
•
The music-on-hold (MOH) feature allows a caller to hear music when that caller is placed on
hold. Music-on-hold can be provided through a two-wire TN2183 analog line circuit pack (or
equivalent) or auxiliary trunk circuit pack to a customer-supplied music source on a Media
Gateway.
Figure 327 shows the connections for music-on-hold, dial dictation, or recorded announcement features
when the music source is Federal Communications Commission (FCC) registered (or equivalent). Figure
328 shows the connections when the music source is not FCC-registered (or equivalent).
Local music-on-hold allows one music source. However, if you purchase the multiple music-on-hold
(tenant partitioning) feature, you can have up to 100 music sources.
NOTE:
Use the following connection instructions when the music source is not located in the
equipment room. If the music source is located in the equipment room, do not route the
connections through the information outlet.
