Strata DK I&M 6/00
A cord of up to 10 meters connects the ISDN BRI RJ45 wall jack to the desktop TE-1 or TA RJ45
jack. Bellcore recommends that all TE-1 and TA devices be attached with the same standard cord
to ensure compatibility.

The standard pinouts for ISDN jacks is the TIA-568A or TIA-568B jack as listed in
.
The variants A and B to the TIA specification are electrically the same, only the wire colors are
different. However, you should only use one type TIA jack in a customer installation because
mixing the two may cause certain wire pairs to be swapped which would result in line faults.

Notes
●
Pins are numbered left to right when looking into the jack cavity with the locking tab down.
●
TIA-568A swaps pair two with pair three, changing only the color of the wires on the pins.
Electrical performance is the same.
