Chapter 8 Performance Monitoring
Enabling Pointer Justification Count Parameters
A consistent pointer justification count indicates clock synchronization problems between nodes. A
difference between the counts means the node transmitting the original pointer justification has timing
variations with the node detecting and transmitting this count. Positive pointer adjustments occur when
the frame rate of the SPE is too slow in relation to the rate of the STS 1.
For pointer justification count definitions, depending on the cards in use, see the “EC1 Card Performance
Monitoring Parameters” section on page 8-14, the “OC-3 Card Performance Monitoring Parameters”
section on page 8-36, “OC-12 Card Performance Monitoring Parameters” section on page 8-41, or the
OC-48 and OC-192 Card Performance Monitoring Parameters, page 8-46.
On CTC, the count fields for PPJC and NPJC PMs appear white and blank unless they are enabled on
the Provisioning > Line tabs. Figure 8-10 shows the PJStsMon# menu on the Provisioning screen.

Procedure: Enable Pointer Justification Count Performance Monitoring
Step 1 Open the LTE card of choice. Double-click the card’s graphic in the main (node) view or right-click the
card and select Open Card. (Clicking a card once highlights the card only.) See Table 8-4 for a list of
