Table 6-3. E1/T1 Statistic Parameters (Cont.)
Alarm Description Recommendation
Inband Loop T1 interface only. Displays the current status of the inband loopback.
External – Loopback Location (Configuration > T1 Physical Layer
Configuration > T1 Loopback Configuration) is set to Local System and
IPmux-8/16 detected a loopback activation code sent from the adjacent
TDM device.
Internal – Loopback Location (Configuration > T1 Physical Layer
Configuration > T1 Loopback Configuration) is set to Remote System
and IPmux-8/16 detected a loopback activation code sent from the
adjacent TDM device. This indication appears in the remote IPmux-
8/16.
Disable – No inband loopbacks are currently active.
LLB Loop T1 interface only. Displays the current status of the inband loopback
activated via F-bit.
On – Leased Line (Configuration > T1 Physical Layer Configuration) is
set to Disable and IPmux-8/16 detected a loopback activation code sent
from the adjacent TDM device on the F-bit.
Off – Leased Line (Configuration > T1 Physical Layer Configuration) is
set to Enable or IPmux-8/16 does not detect a loopback activation code
sent from the adjacent TDM device on the F-bit.
Transmitting
Loop Code
T1 interface only.
On – The local IPmux-8/16 has received indication from the remote
unit configured to the Transparent mode (Configuration > T1 Physical
Layer Configuration > T1 Loopback Configuration > Loopback
Location) that the remote TDM device is transmitting an inband
loopback code.
Displaying E3/T3 Statistics
E3/T3 statistics refer to the physical status of the E3/T3 traffic reaching the IPmux
from the adjacent E3/T3 device.
Path: > Performance Monitoring > Physical Port Statistics > Slot # 3/4.

To view the E3/T3 connection statistics:
1. From the Main menu, select Performance Monitoring.
2. From the Performance Monitoring menu, select Physical Port Statistics.
3. From the Physical Layer Statistics menu, select Slot # 3 or Slot # 4.
Physical Port Statistics screen for E3 or T3 port is displayed (see
Figure 6-4).
Table 6-4 explains the E3/T3 statistic parameters provided by IPmux-8/16.
4. From the Physical Port Statistics menu, select Interval and enter the number of
the 15-minute, which statistics you intend to display (1–96), or type N or P to
browse the stored interval statistics.
