110 Patch Panel?
This is another key to understanding today's telephony infrastructure.
If you get a handle on how it all ties in - that's a good thing.
This graphic shows how you might Cross-Connect a Telephone Line from the IDF (Intermediate Distribution Frame) to the Station Patch Panel.
Note: The Cross-Connect is usually a 24 AWG 1 Pair-Count White/Blue - Blue/White Jumper!
To add a second Station Phone Line, Modem, Fax or BRI ISDN:
- 568A - Cross-Connect to the Green Pair on the same C4 (Station-side).
- 568B - Cross-Connect to the Orange Pair on the same C4 (Station-side).
Use a 2-Line Splitter on the Voice-side of the Station Jack. Separate dial-tone will be available on each side of the Splitter.
Note: Regard the C5 on the Station-side as a C4. The 25th/50th/75th/100th Pairs (color-code Slate) are ignored!
