VoIP Board

Board Description

The VoIP board contains a digital signalling processor (DSP), 4x10/100BaseT Ethernet switch and a small carrier board with the licence chip. The main board is designed on a 6-layer PCB of the size of 160x100mm. Two board status LED indicators are located on the front panel. Configuration (e.g. used voice codecs, IP setting) is completely managed by the main CPU and made via a standard web interface. There is no fixed memory (EEPROM) for the VoIP card firmware. The firmware is saved on the basic CPU and uploaded to the VoIP card upon every VoIP card start/restart.

 

 

  1. PWR – board supply indication
    • Shining: Switched on
    • Flashing: Board in the sleep mode
  2. INIT – board initialisation indication
    • Shining for two minutes: Firmware uploading and configuration in progress
    • Continuous shining: Board initialisation failure
    • Light off: Board initialised successfully
  3. Four RJ45 connectors of the internal 10/100BaseT Ethernet switch

The VoIP board is designed as a media gateway. It works only with media packets (RTP); signalling packets (SIP) must be routed to the basic CPU IP address.

Tip

  • You have to restart the VoIP card upon any VoIP configuration change.

Caution

  • For a successful VoIP card initialisation, the VoIP board MAC address has to be filled in correctly and the basic CPU must be switched to the VoIP-SIP mode and contain the VoIP firmware file.
  • The integrated Ethernet will not work until the VoIP card has been initialised successfully.

Configuration Jumpers

There are no configuration jumpers on the VoIP card.
