Algo 8190S User Manual page 48

RTCP Port Selection
Select the port on which RTCP packets will be sent or received. If using the 'Next Higher
Port' option, ensure that the default multicast zone definitions are modified such that
zones are only assigned to even-numbered ports, leaving the next higher odd-numbered
ports free for RTCP packets.
Zone Definition
The "Expanded" Slave or Master zones can be enabled/disabled in Basic Settings >
Multicast. Default IP addresses and ports may be revised for any given zone in the table.
Important: Ensure that the Address and Port settings are the same for all master
and slave devices.
Page Tone and Page Volume
When an Algo device is the multicast Master, a page tone will play on the Slave device, so
it is recommended to set the Slave tone to "None". If a page is received from a non-Algo
device that doesn't send a tone, a tone can be inserted on the Slaves (above) each time
they detect page audio starting, allowing them to play a tone.
By default, the same page volume can be set for all Slave zones in the Basic Settings >
Features tab. Unique page volumes may be revised on a per-zone basis in the table
above. For instance, emergency pages can be louder on certain Slave speakers.
Strobe Pattern
When the 8190S is in multicast Slave mode, a strobe pattern will flash each time a
multicast stream is detected.
By default, the same flash pattern can be set for all Slave zones in the Basic Settings >
Features tab. Unique flash patterns may be revised on a per-zone basis. For instance,
emergency pages can be different on certain Slave strobes.
Polycom Slave Tones
Available if Multicast Slave and "Polycom Group Page" or "Polycom Push-to-Talk" are
selected in the Basic Settings > Multicast tab. A tone may be set for any of the 25
Polycom Groups. If using an Algo device as a Multicast master, it is recommended to set
the slave tones to "None" to avoid conflicts, as the Algo devices already multicast a tone
by default.
