Separate inputs are provided for Background Music and Music-on-Hold (MOH). This allows one 
music or sound source to be used for background music and another music or sound source to be used 
for music on hold. 

A typical advantage of this is playing a pre-recorded promotional tape to held parties (since many 
may be customers) while providing a selected background music for use in the office.

Background music requires an SCC card (VB-44181). Both Background Music and MOH (if 
using external MOH) require a sound source.

When backup batteries are installed, the System will continue to operate in the event of a power 
failure. If using Battery Backup, backup batteries must be installed in each CCU.

A fully loaded system will operate at least 30 minutes on backup batteries.

Any device connected to the System but that does not derive its power from the System must 
have a backup power source to operate. These devices include any System Message Detail 
Recording (SMDR) (Call Logging) printer (or recorder), fax machine, answering machine, 
modem, cordless telephone, etc.

The System is designed to support easy expansion. Each CCU in the System supports 96 ports (12 
flexible slots) as well as 2 option slots. Up to 6 CCUs may be installed in the System for a total of 576 
ports. 

Up to 2 expansion CCUs may be connected to a base CCU. When a fourth CCU is required, another 
base CCU is installed. Up to 2 expansion CCUs may be connected to the second base CCU.

This building block approach allows you to easily add equipment when needed without a major 
interruption in service or a major delay.
