CHAPTER 4. STATION WIRING
Patch Cord/Jumper Installation And
Administration
Before starting the patch cord installation, obtain a copy of the Port
Assignment Record forms (Figure 4-11) from the customer or marketing
representative. These forms contain the port assignments and identify
the extension numbers (Terminal No.) of the telephones/voice terminals.
Enter the jack assignments at the equipment room and indicate if
adjunct power is required and where it is provided (cross-connect field,
site/satellite closet, or information outlet).
When satellite locations are provided, enter the satellite letter
designation (A through F) and the jack appearance in the equipment
room on the form. Also, enter the floor designation and/or building
designation if appropriate. For 1-point administration (Figure 4-12), this
entry is all that is required. The white field number always corresponds
to the station jack number at the satellite location blue field.
For 2-point administration (Figure 4-13), the station jack numbers (blue
field) at the satellite locations must also be entered on the form. For
example, the entry A1-10 indicates satellite location A, white field
position 1 at the equipment room and the satellite location, and station
jack number 10 at the satellite location.
