Modules MC+1-3 Technical Information ■ The MC+1-3 central control module is powered by the group 1 power supply unit. ■ The MC+1-3 central control module has a plug-in card (MSUB-MRAM) with 128 Mbytes of main (random access) memory. Please note: This plug-in card must not be exchanged by service personnel. In the event of a malfunction, the entire MC+1-3 central control module must be sent in for repair. ■ The MC+1-3 central control module has a CompactFlash slot (MSUB-MFL, PCMCIA interface) for CompactFlash cards. The following data are stored on the CompactFlash card: the OpenCom 510 firmware, the system terminal software, the configuration data and all customer data such as audio files for the internal voice mail system. Note: Only licensed cards may be used. These are currently (May 2004) special 256-Mbyte cards by SanDisk. Contact your DeTeWe distributor or local retailer if you want to purchase one of these cards. ■ The Ethernet port (10/100 Mbits/s) can be used to connect the OpenCom 510 to the LAN. ■ The V.24-1 interface can be used to connect additional apparatus, e.g. a computer for analysing call charges.
