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 7-6 describes 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.
