Each option module contains a variety of performance and alarm status information. Although default 
values reflect the most common configurations, several features of each module are user-configurable. All 
option modules contain an extensive self-test as well as tests designed for the technology they incorporate.

The T1/PRI Network Interface Module provides one channelized T1 or PRI interface. This interface 
operates in DS-1 or DSX-1 mode and can deliver timing for the system. The ATLAS 550 domestic system 

 

(P/N 1200305L2) ships with one installed T1/PRI Network Interface Module.

The E1/PRA Network Interface Module provides one channelized E1 or PRA interface using either a 
standard DB-15 or BNC connector. This interface operates in CCS or CAS signaling mode and can deliver 
timing for the system. The ATLAS 550 international system (P/N 1200306L2) ships with one installed 

 

E1/PRA Network Interface Module.
