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 person-
nel. 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 com-
puter for analysing call charges.
For information on the V.24 interface pin assignment, refer to COM Port starting
