<DIV><FONT color=#000000 size=2>Has anyone used ISDN digital telecomms
components (Siemens, Mitel, etc.)?</FONT></DIV>
<DIV><FONT color=#000000 size=2></FONT>&nbsp;</DIV>
<DIV><FONT color=#000000 size=2>Apart from the obvious use in digital telephones
and telephone systems, these would appear to have many other potential uses -
eg. digital audio transmission and routing, compressed video transmission,
etc.</FONT></DIV>
<DIV><FONT color=#000000 size=2></FONT>&nbsp;</DIV>
<DIV><FONT color=#000000 size=2>I am finding the data sheets difficult to
understand.&nbsp; They assume a knowledge of ISDN terminology and protocols that
I do not have!&nbsp; The applications that I have in mind may not need to be
ISDN compatible - basically I am interested in routing combined digital audio/
compressed video and control data from A to B.&nbsp; However, no doubt, it would
be best if I keep to standard protocols which would then also allow the data to
also be routed between sites over a telephone line.</FONT></DIV>
<DIV><FONT color=#000000 size=2></FONT>&nbsp;</DIV>
<DIV><FONT color=#000000 size=2>Components I have been looking at include
Siemens PSB2186 (&quot;Terminal Equipment&quot; end - to use the jargon)
communicating with PEB2084 (quad transceiver).&nbsp; This would involve a four
wire link.&nbsp; Alternatively, a two wire link could be implemented with
PSB2196 and PEB2096.</FONT></DIV>
<DIV><FONT color=#000000 size=2></FONT>&nbsp;</DIV>
<DIV><FONT color=#000000 size=2>A microcontroller is used to set up registers
and to handle the various protocols.</FONT></DIV>
<DIV><FONT color=#000000 size=2></FONT><FONT color=#000000 size=2>What I need to
know is how to get these devices to &quot;talk&quot; to each other.&nbsp;
</FONT></DIV>
<DIV><FONT color=#000000 size=2></FONT>&nbsp;</DIV>
<DIV><FONT color=#000000 size=2>Examples of code for any micro would be very
helpful.&nbsp; Equally, I should appreciate any pointers to sources of
information/ recommended books relating to ISDN, etc.</FONT></DIV>
<DIV><FONT color=#000000 size=2></FONT>&nbsp;</DIV>
