Power-Related Hardware 3
Your Lucent Technologies representative can plan for added power-related
hardware to provide your system with additional power and protection from power
surges, although most systems do not need extra surge protection. Other
accessories apply to system-specific conditions.
Power Accessories 3
In a power failure, battery backup units can keep the system running for several
hours. When you connect adjuncts and adapters to telephones, the power
requirements for the telephones and the system increase. Sometimes it is
necessary to add a power accessory, described in this section, to an individual
telephone or to the system to accommodate these additional needs.
1. Release 5.0 and later systems only; in earlier releases, a group can have only one primary
announcement device.
2. If you use equipment that rebroadcasts music or other copyrighted materials, you may be
required to obtain a copyright license from and pay license fees to a third party such as
American Society of Composers, Artists, and Producers (ASCAP) or Broadcast Music
Incorporated (BMI). Or you can purchase a Magic on Hold system, which does not require
you to obtain such a license, from Lucent Technologies.
