Displaying E1/T1 Group HDLC Statistics

When the E1/T1 timeslots are configured to carry the HDLC data, Vmux-2100 collects HDLC traffic statistics (see Figure 7-15). Table 7-6describes the HDLC statistics values.

To display the E1/T1 group HDLC statistics:

1.From the Cards Statistics menu , choose HDLC statistics.

2.From the HDLC Statistics menu, choose Slot> and then enter the desired slot number from the displayed list to select the slot.
