For a quick understanding of how telephone systems are configured, see the attached Telephone System Diagram.  Installing a telephone system involves three discrete tasks.

First is the wiring  

Our service centers also install voice and data cabling.  However, you probably don't need new wiring if there are telephone jacks where you want them now.  Unlike some systems (such as Lucent systems which require four pairs of wires for each telephone), our digital system uses only one pair of wires for each telephone. 

Second is the cabinets and phones 

This involves mounting the system cabinet and connecting it to both the outside telephone lines and the wires that go to the telephone jacks.  Modular cords plug into the system cards and are "punched down" on standard telephone system termination blocks.  From there, the system blocks are "cross connected" to the telephone lines and telephone instruments using industry standard color codes.  Once the telephones are plugged into standard telephone jacks, the system is turned on and comes up running. 

Third is custom programming

The system has default programming which is sufficient in many situations. And users can program the features they desire on the spare buttons on their telephones.  However, if you desire custom programming, we accomplish it through the use of standard modems. We can access your system remotely for a modest hourly charge (presently $50 per hour with a 1/2 hour minimum).  This means that you are not dependent upon any installer's specific knowledge of system programming nor on the system's default programming.
