Code

Codec for a P.O.T.S. line

JavaScript
It starts the concept of a codec. Hopefully at completion we arrive at the concept of stacking
/*
#START HELP

#Programm

     Program Name: Codex (P.O.T.S.).js
     Program Code: Java Script
     Company:      Integrated Control Systems
     Programmer:   Ralph Clark

#Design Control (future)
      
     A. The module % 3 parts  -  
          classifies a spreadsheet w/ hardware && expansionary build
     B. phonebook, autodial, database information with call request
     C. keypad, active call features, isolated dialing options
     D. Codec software integration, technical calling options, hardware
        parameters

#Debugg Information 

     1 - Primarily it is to create the secondary sheet composition.
     2 - the codec is really better placed on another script page.
     3 - saving the device [Codec} function for universal commands.
     4 - The input number 'n' on device function {changes} value to keep
         integrity.
