0 for the first ISDN PRI interface.
➤
Select ISDN Switch Type: autodetect on bootup.
This setting enables X4000 to use its automatic D-channel detection. As
long as the D-channel detection is running, running appears next to Result
of Autoconfiguration. The setting found is then displayed, e.g. Euro ISDN
S2M user profile (TE).
➤
Select ISDN Line Framing, e.g. standard (CRC4).
➤
Select Clock Mode, e.g.
external.
Clock Mode Defines which connection partner sends the
clock signal for synchronization between
transmitter and receiver. If the clock signal is
not generated by the (PABX) network itself, one
of the two connection partners must generate
this signal.
Possible values:
■
external (default setting): X4000 receives
the clock signal
■
internal:
X4000 sends the clock signal
Field Meaning
If the ISDN protocol is set incorrectly, an ISDN connection cannot be set up
and the provider’s exchange may disconnect the line if it is not used!
Make sure X4000 detects the ISDN protocol used correctly and displays it
under Result of Autoconfiguration. If not, enter it manually under ISDN
Switch Type. The automatic D-channel detection is then switched off.
