Does anybody know the pinouts of the DB15 to RJ45 connector, Nortel use this for the E1/T1 connection to smartjack or Telco.

Thanks.

The RJ45 pins 1 and 2 connect to DB15 3 and 11 and
RJ45 pins 4 and 5 connect to DB15 1 and 9

If transmit and receive are rolled, then
pins 1 and 2 connect to 1 and 9 and
pins 4 and 5 connect to 3 and 11

 
Code:
	DB15 HOOD
RJ45			DB15	OR	ROLLED DB15 (USED IN SOME DEMARKS & ROUTERS)
Wht/Org 1 BLUE -------- 1 XTIP  	11
Org/Wht 2 ORNG -------- 9 XRING		3

So which is it? I have an rj45 to DB15 adapter I am using to hookup pbx(db15 side) to a voip gateway device (rj45 side).
What colors go into which holes?

Almost there vztech :)
so the colored wire pins are :
red
blue
green
yellow
black
brown
orange
white

which i have to stick into holes numbered 1-15.

Again, which colors into which holes?

thanks
 
the colors are not as important as the pin numbers. different manufacturers use different wire colors. so, here is the pinout from Nortel NTP 553-2901-200

DB 15 pin # RJ pin number Function
1 5 transmit tip to telco
9 4 transmit ring to telco
3 2 receive tip from telco
11 1 receive ring from telco
 
I always connect to amphenol cable:
