Figure 2-25. ACS-165 Drop and Insert System  

A three-location system can provide circuits between these locations  

●

 

1 and 2 

●

 

2 and 3 

●

 

1 and 3 

The only limiting factor is the 24-time slot capacity of the T1 circuit between any two adjacent 
locations. Drop and insert systems are not limited to a single drop and insert multiplexer. In fact, you 
can use them to link as many as one hundred locations.
