In typical analog phone applications, the exchange side modem  and the subscriber side modem are used in pair as shown in the above diagram.  
These two modems are linked together using multimode fiber or singlemode fiber as per site requirement.  
The exchange side modem is connected via analog twisted pair telephone or RJ11 to PBX system and the subscriber side modem is connected via analog twisted pair telephone or RJ11  to analog telephone.  The subscribe side modem most probably contains a ring generator whereby it generates a ring tone to the analog telephone.
In most cases the exchange side modem  and the subscriber side modem are both able to add in a data modem transmission of type RS422 or RS485. The data modem is connected to both modem via twisted pair cable or RJ 45 type.
There many types of fiber optics modems in the market nowadays. The designer should design his or her network in accordance to availability of fiber optics modem specifications.

When to use IP CCTV and Analog CCTV?

Application of IP CCTV Solution
  • Those who need to monitor events in real time 
  • Transmission of both full-motion and still images over LAN networks
  • To keep an eye on employees and customers in real time
  • Able to log onto any computer at any time 

Application of Analog CCTV Solution
  • View of CCTV frames rates that look like real life is acceptable to end user
  • Transmission standard of PAL or NTSC
  • Separate cable for separate vidoe surveilance
  • Low light is a factor 



In order to design IP CCTV we need to consider in reducing cost by selecting the right IP video network and appropriate networking equipment infrastructure as IP digital video requires large amount of bandwidth and network speeds to be fast.
