Module Interface Ports and Pins.

 The SocketSLIC interface 

module uses channel associated signaling (A and B bits) 
to control the analog interface. (It can be programmed to 
support unique interfaces per specific customer installation 
requirements.)

Reduces Development Time.

 The SocketSLIC interface 

module actually provides faster time-to-market because 
it relieves the burden and expense of designing the analog 
interface. This complete, ready-to-integrate analog module 
allows you to enhance your product while you focus on 
developing its core features.
