asterisk users - Jan 2005 - OT: TE405P pins and slots

Just got our 4 port T1 card. I know that I don't have any need to use these
parts..this is simple curiosity.

What are the 2 expansion slots for? I see a group of pins at the top called
'timing'; what they are for? There is a small dial called
'ident'; whats it
for? I'm guessing that the pins labeled 'test' are for manuf testing
of the
card.

Card looks very well manufactured. Kinda hard to believe that it costs
$1,500 when a SCSI RAID card that has more hardware on it costs about 1/2
that.

I imagine the "Expansion" is for more spans -- nothing has been
designed for
them at this point.  Timing is likely for carrying timing across multiple 
cards, Test for testing and ident is for card order when multiple cards are 
inserted into one system.

Do *you* have a mass-produced quad-span PRI card to sell?  I believe the card 
is priced for what the market will bear, which is the exact right thing to 
do.  :-)

The timing port can be really usefull if the drivers can be changed 
along the lines of http://florz.dyndns.org/zaphfc/.

Timing is probably for external timing sources, like gps receivers or in
telco arenas it's common to get timeing and have a clock slaved to it and
all channel banks are externally timed to that synced clock.
