: How does the IPmux handle/propagate alarms on the TDM and Ethernet side? 

: The IPmux handles alarms on the TDM and Ethernet side in the following 

manner:  

Unframed mode: 

 

In case of LOS (Loss Of Signal) on the local IPmux side, AIS will be sent 
towards the IP side, and will then be transferred over the E1/T1 to the 

remote TDM device.  

 

All other alarms sent from the near-end TDM device (including information 
on timeslot 0), will be propagated transparently by the local IPmux, to the 
remote end TDM device (over the IP connection).  

 Framed 

mode: 

 

  In case of LOS/LOF/AIS detected on the local IPmux side, a user-configurable 

conditioning pattern (00 to FF) will be sent on the relevant timeslots (over the IP 
connection), to the far-end TDM device. A user-configurable conditioning 
pattern can also be applied on the ABCD bits (CAS signaling 1 to F) going 
towards the remote PBX.  
The frame synch on the E1/T1 level is maintained in favor of the end TDM 
devices.  
 
Ethernet Side Alarms 
Unframed mode:  
In case of local failure on the IPmux, or a situation of jitter buffer 
underflow/overflow, an (unframed) AIS will be sent towards the near-end TDM 
side.
