Equipment Room Hardware And Cabling Installation
Label Code 224A—Blue Labels (comcode 103 970 042)
Label code 224A contains the following labels:
●
●
●
●
●
●
(35) blue labels (Figure 3-32) that identify 3-pair station circuits
from the equipment room. Each label identifies sixteen 3-pair
station circuits. The labels are numbered sequentially from 1 to
560.
(40) blue labels (Figure 3-33) that identify 4-pair station circuits
from the equipment room. Each label identifies twelve 4-pair
station circuits. The labels are numbered sequentially from 1 to
480.
(102) blue labels (Figure 3-33) that identify 4-pair station circuits
from the satellite closet. Each label identifies twelve 4-pair station
circuits. There are labels for satellite closets numbered A through
F, and each satellite closet has station circuits numbered 1
through 204.
Unnumbered blue labels (Figure 3-32) that identify 3-Pair station
circuits from the equipment room. Each label identifies sixteen
3-pair station circuits.
Unnumbered blue labels (Figure 3-33) that identify 4-pair station
circuits from the equipment room. Each label identifies twelve
4-pair station circuits.
(28) unnumbered blue labels (Figure 3-34) that identify 4-pair
station circuits from the satellite closet. Each label identifies
twelve 4-pair station circuits.
4-PAIR BLUE STATION LABELS
The labels shown in Figure 3-33 identify 4-pair station appearances at
the cross-connect field. The top labels are numbered and installed in
sequence (1 to 480) starting with the first terminal block in the blue field.
The bottom label must be filled in manually. The labels shown in Figure
3-34 identify 4-pair station circuits from the satellite closet. The top
labels are grouped and numbered in sequence A 1 to A 204 through F
1 to F 204 to correspond to the satellite locations and information
outlets.
