011504 InformaCast® Enabled Ceiling Speaker

IP multicast is a technique for one-to-many communication over a local IP network. IGMP multicast is sent via UDP packets from a multicast server to a multicast receiver. This stream scales to a larger receiver population by not requiring prior knowledge of who or how many receivers there are. Multicast uses network infrastructure efficiently by requiring the source to send a packet only once, even if it needs to be delivered to many receivers. The network replicates the packet in order to reach multiple receivers only when necessary.

Multicast is a great alternative to SIP registration as it does not require that the recipient of the stream to register as an extension on an IP-PBX server.

CyberData products support both regular IGMP multicast as well as proprietary Polycom Group Paging.

Check to see if your current firmware is the latest version before attempting to update. Download the latest version firmware which includes the Update Firmware Utility. To upload the firmware from your PC, see the Upgrading the Firmware section of the VoIP V2 IP Speaker Operations Guide. See the Downloads tab.

Yes, our speakers are compliant with RFC 3261, but not every SIP extension is fully supported such as extensions for certain phone features that our speakers do not require.

Page groups are found in the extensions_additional.conf file in Asterisk. The paging group portion of this file should read as follows in which "101 and 102" are the usernames and extensions of two speakers and "103" is the extension used to call the paging group of speakers 101 and 102, and "105" is the extension to call speakers 101,102, and 104:

MAST

MAST can handle ulaw and alaw as well as streaming from a mic to a speaker.

Linphone:

Linphone has a test application called rtpsend that streams data out as ulaw by default. (It may be trivial to modify this to send in other formats).

This is a common problem when the re-registration time value is not set correctly.

On our device, you need to make sure that the re-registration time value (in minutes) is less than that is set on the IP-PBX server.

This High PIV Ultra Fast switching diode prevents CEMF kick back from an intermediary relay coil when power is cut and the coil field collapses. You could use an On-Semi MUR105 diode.

Pantel, Cisco, or Linksys PoE endpoints all work on the Dell Powerconnect 3524P.

A user tried hard coding the switch speed/duplex and tried four different Dell Powerconnect 3524P switches. --- Check to make sure the Dell Powerconnect 3524P has flow control enabled on the port for the CyberData device to power up properly.

According to Dell: Flow Control Support (IEEE 802.3X): Flow control enables lower speed devices to communicate with higher speed devices by requesting that the higher speed device refrains from sending packets. Transmissions are temporarily halted to prevent buffer overflows. For information on configuring Flow Control for ports or LAGs, see "Defining Port Configuration" or "Defining LAG Parameters" in the Dell© PowerConnect© 35xx Systems User's Guide.

In a ceiling mount, you would want about 1 per every 10-15 feet of hallway length.

If you used the paging amp you could use 3 paging amps per 100 feet as per this drawing.

This assumes average ambient noise and surface attenuation levels.

The following figure shows the 011061 V2 Paging Amp and the 011068 Horn Loudspeaker:

The cables or switch ports that you are connecting to are set in switch or hub mode instead of endpoint stations. The MDIX setting needs to be changed to MDI since our VoIP products are end stations.

From the Cisco SLM 224P User Guide:

Change to MDI:

MDI / MDIX ­ Displays the Media Dependent Interface (MDI) / Media Dependent Interface with Crossover (MDIX) status on the port. Hubs and switches are deliberately wired the opposite of the way end stations are wired, so that when a hub or switch is connected to an end station, a straight through Ethernet cable can be used, and the pairs are matched up properly. When two hubs or switches are connected to each other, or two end stations are connected to each other, a crossover cable is used to ensure that the correct pairs are connected. The possible field values are:

Please adjust the switch power selection to Power inline static, as opposed to Power inline dynamic. This will allow the device to continuously receive 15.4W of power.

There are known PoE limitations with third party devices on the Cisco Catalyst series switches. This includes the 2500, 3500, and 6500 series switches.

Its important to keep in mind that CyberData devices are considered third party devices and require switch port setting adjustments.

Be sure to turn power policing off if it has been enabled on your switch. Power policing is disabled by default. Also, configure your port for no shutdown.

Use the following command to configure inline power: power inline static max 15400
