E/M Type II provides a four−wire fully−looped arrangement that provides full isolation between the 
trunks and signaling units. The following table displays the sent signal states for active/not active 
signaling. The RBS grounds its M−lead to signal a seizure. The other device applies battery to its 
M−lead to signal a seizure. Prod-El SRB expect to see active conditions on the E−lead and signal 
active to the remote device on M−lead. 
 
 
E/M Type V Interface Model
 
E/M Type V interface is a symmetrical two−wire lead arrangement that signals in both directions by 
means of open for not active and ground for active signalling. The following table displays the sent 
signal states for active/not active signaling. The RBS grounds its M−lead to signal a seizure. The other 
device applies battery to its M−lead to signal a seizure. Prod-El SRB expect to see active conditions 
on the E−lead and signal active to the remote device on M−lead. 
 
E/M Proprietary Type Interface Model
 
E/M Proprietary Type provides a four−wire fully−looped arrangement that provides full isolation 
between the trunks and signaling units. The following table displays the sent signal states for 
active/not active signaling. The RBS grounds its M−lead to signal a seizure. The other device applies 
battery to its M−lead to signal a seizure. Prod-El SRB expect to see active conditions on the E−lead 
and signal active to the remote device on M−lead.
