Jack Wiring for Hybrid Phone

[idoelectronics]

Can one of you smart cabling techs give me the exact pinout of the jack for the older hybrid phone connection. Also what pins carry power? 7&8 as is normal for Lucent? Does anyone have a diagram they have a link to - picture etc?

Can you connect the BIS phones to a Hybrid port - TN762? 9030/9031 Transtalk wireless connect ok - do they use the same pinout?

Thanks for the help!

Same wiring as TT Pair 1 (w/bl) pair 2 (w/or) pair 3 (w/gn) based on 568B wiring scheme, circuit is self powered (phantom power). No external power is required. On hybrid phones (73xx),ie: merlin 4/08 thru 30/70, the 4th pair is intercom path, do not use for power.

phonesrus is dead-on on the pinout. Yes you can use the BIS phones, had to do it several times myself with no problems

The way I see it, unless we each conform, unless we obey orders, unless we follow our leaders blindly, there is no possible way we can remain free.
