VoIP (VOIPDB) Daughter Board (Figure 2-16 - Figure 2-16)

The 32VOIPDB, 64VOIPDB and 128VOIPDB daughter boards are used for converting the RTP (Real Time
Transfer Protocol) packets via the IP network and PCM highway. The daughter board is installed on the CCPU.
The IP terminals are connected directly to the IP bus. When IP terminals need to be connected to a
conventional PCM-based digital circuit, this daughter board converts the IP packet signal into a PCM signal
format and connects to the PCM time division switch.
The VOIPDB daughter board is required in order for IP terminals to communicate with non-VoIP UX5000
terminals, as well as to place or receive outside calls.
The VoIP daughter board provides the voice (RTP/RTCP) processing function. The call control function is
mounted on the CCPU. Only one version of the VOIPDB (32, 64, or 128) can be installed on the CCPU at a
time.
The VOIPDB daughter board provides:
32 (32VOIPDB), 64 (64VOIPDB) or 128 (128VOIPDB) channels

When installing a VoIP daughter board, the system will not allocate trunk ports for the daughter board. This
must be defined in Program 10-40-02. Ports are allocated in groups of 4. For IP extensions, the system will
only allocate extension ports once an IP terminal is connected. At that time, the system will reserve a group of
4 extension ports. Once the 4 ports are used, the system will then reserve another group of 4 when another IP
extension is connected.
