DECT

A specific MSN can be seized for individual calls by means of a code number pro-
cedure. For further information, refer to the "OpenCom 100, Operation on
Standard Terminals"user guide.
What are some of the causes for problems when sending and/or receiving
faxes?
In frequent cases, the reason may be found in a problem with the ISDN-L1 ref-
erence clock distribution. The L1 clock is delivered from the network provider. An
unclean L1 clock distribution and the introduced signalling jitter is overheard by
the human ear. Nevertheless, data and fax transmissions may be disturbed by the
jitter. Please check, which ISDN lines will deliver the L1 clock. One of the installed
ISDN interface boards (MX+S01-8 or MT+S2M1-1) should show a steady green
light with LED 3. Details can be found under L1 Clock starting on page 151.
The fax data transfer possibly is routed via a compressing VoIP connection. Please
verify, if the a/b port is configured with the "Fax" setting. For the VoIP connection,
select a VoIP profile which includes the non-compressing G.711 codec.
