     FEATURES  
    
      
        
        
          - SRM-31A is an Asynchronous Short Range Modem 
          that operates full duplex over 2-wire unconditioned lines (twisted 
          pair) at selectable rates from 1.2 kbps to 115.2 kbps. 
 
         
        
          - SRM-31A uses I-DSL technology and 2B1Q line 
          coding. It provides an operating range of up to 8 km, independent of 
          the data rate. An adaptive equalizer provides noise immunity and high 
          performance, over mixed gauge or multi-pair cables. SRM-31A can pass 
          two control signals end-to-end with no data transmission interference.
          
 
         
        
          - SRM-31A is a miniature version of ASM-31. 
          External switches on the bottom of the unit enable easy configuration 
          of the product. Five LED indicators show the status of the unit. The 
          modem requires an external power source via an AC adapter (see 
          Ordering). 
 
         
        
          - SRM-31A can operate opposite ASM-31, ASMi-31, 
          and the HS-U module of Megaplex-2000 and Megaplex-2100. SRM-31A can be 
          configured remotely, and diagnostics can be activated from the other 
          end. 
 
         
        
          - SRM-31A features diagnostic capabilities that 
          include implementation of local and remote loopbacks.
