card can be used to connect RFP 22 base stations.
Analogue ports are suitable for connecting standard analogue terminals.
If your network provider supports the CNIP (Calling Name Identification Presen-
tation) feature, the names of callers will be displayed in addition to the numbers
whenever external calls are received. The OpenCom 510 supports the display of
the name on system telephones. However, if you have created an entry in the tele-
phone book under the number of the caller, this entry will be displayed instead.
