Identifying and Correcting Drift

In cable placement situations where span sections of the cables are too long, the placement crew
can recognize PAM drift and make a determination as to when and where to take corrective
action. After the Zero Marker is attached at the first pole each subsequent span placement
results in a shifting PAM away from the CO. The line technician must be able to recognize the
need to take corrective action early in the placement process. When sufficient drift occurs, a
slack coil can be introduced, bringing the alignment back to zero at that point.
Note: Correcting drift aligns the distribution cable and access points after the slack loop is
made. Access points before the slack loop are not affected. It is important to make corrections
while drift is still within acceptable tolerances, and before the drift is unacceptable.

SAM Marker

Yellow slack alignment markers (SAMs) mark the beginning and ending points of engineering
designed slack lengths. One of the SAMs is always located next to a PAM, indicating the start of
a slack loop. If no slack adjustments are required, a slack loop is made and the two yellow SAM
markers align with each other. If an adjustment needs to be made in either direction, make a
slack loop and align the SAM furthest from the PAM at the pole where the PAM would be
located, before continuing the placement to the next pole/hand-hole.
