Installing Telephones and Adjuncts
Modems
Connect the modem to one of the following, as described earlier in this
section:
single-line telephone
MLX telephone with an MFM
When connected to the TEL/OTHER
calls made from the modem are independent of the associated MLX
telephone. Data calls can be dialed from the data terminal keyboard
or an associated single-line telephone.
GPA and analog multiline telephone
See Chapter 6 for complete information connecting modems and other
data equipment.
Music-on-HoId, Magic On Hold
Connect the music device to an LS or GS trunk jack that is programmed for
Music-on-Hold (MOH). The system supports one MOH connection, either
Magic On Hold or a customer-owned music source. The external music
coupler (PEC 61398) uses an 8-ohm music source and two attenuation
controls for setting the MOH music level.
PagePac 20 equipment can be used with a loudspeaker system to
provide music, and paging without a music coupler.
If equipment is used that rebroadcasts music or other copyrighted
materials, the customer may be required to obtain a copyright license
from and pay license fees to a third party such as the American
Society of Composers, Artists, and Producers (ASCAP) or Broadcast
Music Incorporated (BMI).
To bypass the license requirement, the customer can purchase a
Magic On Hold system, which does not require such a license, from an
authorized dealer.
Figure 3-11 and Figure 3-12 show various configurations via single-zone and
multizone paging.
