2.2.5 elmeg C88m: Internal/external ISDN connection 3
The internal ISDN connection 3 can be switched to an external ISDN connec-
tion. In the initial state this connection is set to an internal ISDN connection.
When the jumpers for the ISDN connection 3 are removed and programming
is performed appropriately, the connection can be switched to an external ISDN
connection. The internal ISDN connection is effected at terminal block S03:
INT/EXT; the external ISDN connection at ISDN jack S03: EXT.
First remove the jumper for switchover for external connection (see Fig. 9)!
