VoIP (16VOIPU) PCB (Figure 2-19)
The VoIP PCB is used for converting the RTP (Real Time Transfer Protocol) packets via the IP net-
work and PCM highway. The IP telephones are connected directly to the IP bus. When IP phones need
to be connected to a conventional PCM-based digital circuit, this PCB converts the IP packet signal
into a PCM signal format and connects to the PCM time division switch.
The 16VOIPU PCB is required in order for IP telephones to communicate with non-VoIP Aspila EX
phones, as well as to place or receive outside calls.
The 16VOIPU PCB provides:
• 16VOIPU PCB provides up to 16 channels
• Connector for the VOIPDB daughter board (providing an additional 16 channels)
• 1 PCB status LED
• 1 run/block switch
A maximum of 6 PCBs per system are allowed, providing 96 channels (with the daughter board, 192
channels), it can be plugged into any universal slot.
If a separate software hub is used (and not the 8SHUBU PCB), it should be a 100Base/full duplex hub.
To avoid network problems and to ensure good voice quality, do not use a Repeater Hub/10Base.
