• The VoIPDB uses two addresses, one address is for signaling and the other address for voice
traffic.
• An on-board RJ-45 connector provides a WAN/LAN connection. Voice and signaling data to/from
the IP Stations are converted into IP Frames and transmitted through the Data Communication IP
Network.
• The VoIPDB supports a maximum of 112 VoIP connections.
• Duplex mode (Auto or Full) and speed (10 or 100 mbps) are configured via SL2100 unit
programming.
In voice communication, particularly Internet telephony, the
M
ean
O
pinion
S
core (MOS) provides a
numerical measure of the quality of human speech at the circuit destination. The scheme uses
subjective tests (opinionated scores) that are mathematically averaged to obtain a quantitative
indicator of the system performance. The maximum MOS is 5.0.
• SL2100 supports a 100 rel option and Session Timer option.
• SL2100 supports Early Media.
