To configure individual T1 in channelized T3:
1. Follow the path above to access the CT3 T1 1–28. Layer Configuration menu
(
Figure 4-12).
2. From the CT3 Ext. Layer Configuration menu, configure the following:
 Channel Status
 Enable (T1 link is enabled)
 Disable (T1 link is disabled)
 Line Type (T1 framing mode)
 Unframed (Framing is not used)
 T1-D4 (12 frames per multiframe)
 T1-ESF (24 frames per multiframe)
IPmux-16 transmits internal T1s as unframed streams. However, the unit detects
alarms related to the internal T1 framing. This is why it is important to select the
correct T1 line type, which is also required for transmitting the Far End TDM Fail
alarm in TDMoIP V2.
 Restore Time (time required for the T1 port to return to normal operation
after sync loss):
 1 second
 10 seconds
