Chapter 2 - PCB Installation and StartupChapter 2 2 - 332.4.5 VoIP (VOIPDB) Daughter Board (Figure 2-17 - Figure 2-16)The 32VOIPDB, 64VOIPDB and 128VOIPDB daughter boards are used for converting the RTP (Real TimeTransfer Protocol) packets via the IP network and PCM highway. The daughter board is installed on the CCPU.The IP telephones are connected directly to the IP bus. When IP phones need to be connected to aconventional PCM-based digital circuit, this PCB converts the IP packet signal into a PCM signal format andconnects to the PCM time division switch.The VOIPDB daughter board is required in order for IP telephones to communicate with non-VoIP UX5000phones, as well as to place or receive outside calls.The VoIP daughter board provides the voice (RTP/RTCP) processing function. The call control function ismounted on the CCPU. Only one version of the VOIPDB (32, 64, or 128) can be installed on the CCPU at atime.The VOIPDB daughter board provides:● 32 (32VOIPDB), 64 (64VOIPDB) or 128 (128VOIPDB) channels● 64VOIPDB and 128VOIPDB Only: Layer 2 Switch● 64VOIPDB and 128VOIPDB Only: 10/100/1000 Gigabit Ethernet Connection● 64VOIPDB and 128VOIPDB Only: RTP/RTCP Packet Transmitted/Received Directly32VOIPDB: RTP and RTCP Packeted Transmitted/Received by Fast Ethernet LAN Interface on CCPU● 64VOIPDB and 128VOIPDB Only: 4 PCB Status LEDs● Support for CODECs: G722, G726, iLBCWhen installing a VoIP PCB, the system will not allocate trunk ports for the PCB. This must be defined inProgram 10-40-02. Ports are allocated in groups of 4. For IP extensions, the system will only allocateextension ports once an IP phone is connected. At that time, the system will reserve a group of 4 extensionports. Once the 4 ports are used, the system will then reserve another group of 4 when another IP extension isconnected.2.4.5.1 LED IndicationsLED Function LEDStatus Operation StatusACT (LED 1) Link activity or datatransmission and reception.On Green Link up completedFlashing Data being transmitted/received.LINK10_100(LED2)10Base-T/100Base-TX linkspeed indicator.On Red 100Base-TX link upWhen:LED 1=OnLED 2= OffLED 3=OffLink up 10Base-TLINK1000(LED3)1000Base-T link speedindicatorOn Red 1000Base-T link upDUPLEX(LED4)Duplex Status On Yellow Full duplex operation
