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. -Matthew

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.> Card looks very well manufactured.

I believe the card is priced for what the market will bear, which is the exact right thing to do. :-) -A.

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.
