17. OPTIMAX 2 SYSTEM NETWORK SPECIFICATIONS
OPTIMAX 2 public address system supports audio and control data Communications through Ethernet and IP.
Since it works on levels 3 and 4 of the OSI scale, OPTIMAX 2 protocol supports Communications through routers (IP protocol) by
means of the configurations of the gateways and subnetwork masks. Thanks to these features, OPTIMAX 2 system can work on
both LANs and WANs.
The protocols used by the OPTIMAX 2 system allow working without problems in networks where the different public address
systems are located in different VLANs.
Communications it uses are:
TCP/IP for control communications between different equipment.
UDP Unicast for the audio broadcasting from a local IP microphone to a local OPTIMAX 2 matrix (point to point
communication).
UDP Multicast for the audio broadcasting from a global IP microphone to the OPTIMAX 2 matrixes (point to multipoint
communication).
VoIP: OPTIMAX 2 matrix allows to work also like a receiving VoIP terminal (one call each time) as following standards:
-
Call establishing according to SIP RFC 3261.
-
For zones selection --> DTMF through SIP INFO or RFC 2833.
-
Supports calls "Peer to Peer" or through Proxy server.
-
RTP audio (Unicast/Multicast).
-
Supported audio codecs in VoIP calls:
G711 (µ-law + A-law)
G722
L16 (16 bits / 44.1KHz)
For a properly operation as a VoIP terminal, network has to be configured according to the defined specifications for IP
telephony.
Ports for communications standard services used in OPTIMAX 2 systems:
TELNET
FTP
Ports for the SECURE communication services used in the OPTIMAX 2 system:
SSH
