Chapter 7: Features and accessories

Expansion of the phone coverage

You can use your Avaya Conference Phone B199 on larger conference tables or when the number
of a meeting participants is greater than 10. In this case you can ensure high-level quality of audio
signal by expanding the phone coverage in the room without a PA system. You can do it by
connecting Smart Mic expansion microphones to the phone or by cascading several B199 devices
in a daisy chain.
Expansion of the phone coverage helps to improve the audio quality in large rooms. The
conference phone and two Smart Mics increase the capture range from 30 square meters to up to
70 square meters. Three phones in a daisy chain increase the range from 30 square meters to up
to 90 square meters.
Expansion coverage arrangement
You can arrange a daisy chain with your conference phone and another B199 Conference Phone
or connect Smart Mic expansion microphones. The maximum number of devices connected in a
daisy chain is 3. One B199 phone acts as a central device (a "master") and one or two other units
act as expansion devices ("slaves").
The typical arrangements when the phone's coverage is expanded are the following:
• Master phone — Slave phone
• Slave phone — Master phone — Slave phone
• Master phone — Expansion microphone
• Expansion microphone — Master phone — Expansion microphone
• Expansion microphone — Master phone — Slave phone
Functions of the Master and Slave devices
When B199 Conference Phone acts as a master, it performs all its configured functions.
When B199 Conference Phone is in a subordinate position (a "slave"), it performs the following
functions:
• Play audio received from the master device. The master phone defines the audio
characteristics.
• Send its microphone audio to the master device.
• Receive and indicate mute state changes made on the master device.
• Send information to the master device, when you tap Microphone Muted.
