Patch-by-Exception (PBE) offers multiple advantages as a structured cabling solution, from cost and operational benefits to installation, administration and maintenance advantages.
Additionally, PBE presents advantages when it comes to moves, adds and changes.
We’ve previously explored what PBE is, and how it works when it comes to disconnection modules. But when it comes time to move services for an individual from one location to another, no special tools are required. Moves are done quickly and efficiently with a patch cord.
Engineers must simply plug the patch cord into the work area field at the circuit to be moved and then plug the other end into the new source on the network switch field. The 4-pair patch cord will move all signals from one work area to another in a matter of seconds.
Choosing the right patch cord length (from 4 to 7, to 10 or 15 feet) provides flexibility in patching, and also allows for the best possible performance.
In time, as more and more changes are made, the fields of disconnection modules show all changes that have been made by the patch cords and you may want to make some or all of these changes part of your jumpered solution.
At that time, a technician may be called in to rewire the temporary changes and make them permanent.
This restores the cross-connect fields to their original “patch cord-free” state. The panel will again look like it did the day it was first installed. The removed patch cords are then available for the next round of inevitable moves, adds, and changes.
