[Asterisk-Users] AT&T T1 Cable Needed!

[John Harragin]

After days of searching, I found H600-307. Searching this yeilded a pinout -
ta da!

47 LI (High)
22 LI
48 LO
23 LO (High)

(there is also a loopback pair - but I won't bore you with this)

I get:  I=In, O=Out

Does anyone know if High (telephone lingo) corresponds to tip or ring?
On our normal RJ45 do we transmit (Out) on 1&2 or 4&5?

John

Hi,

I just got a T1 interface for a AT&T (became Lucent) System75 (uses same
cards as Definity). I would take a crack at making a cable but can't
determine the pinout for a cable and it is not apparent from the board.
Asking you guys makes sense as one of you may have one of these systems. The
cable has a amphenol male D50 connector on one end and probably a rj45 on
the other. I also don't know if any other devices are needed between the
System75 and asterisk The DS1 Tie Trunk card is a TN722B.

Any information would be helpful.

Thanks,

John
