Wiring for DB15 E1 card? ihatedx (TechnicalUser) (OP) 12 Mar 08 11:17 Hi,I'm after knowing the pinouts on the DB15 socket on the q931 card in our realitis dx.I want to make a cable to RJ45.Can anyone help?Many thanks in advance.P RE: Wiring for DB15 E1 card? pablo100 (TechnicalUser) 22 Mar 08 05:21 I am not too sure of the pin-outs at the moment, but there is a cable available - part code 1HAU50108 - with a 15 pin db15 plug on one end and the unterminated two pairs on the other. It would then be down to you to feed the individual pairs into an RJ-45 plug yourself.RJ- 45 pin-outs for isdn30 nte's are dx system tx 1/2 (orange pair) dx system rx 4/5 ( blue pair)I will try and get the db15 pin-outs for you and post them here in the near future.Go0d luck!
