Telecommunication Systems are a way to communicate by voice, video and internet connections. There are different telecommunication system types that vary between residential and business environments. Currently, I am employed at a correctional facility that is operated through the State of Colorado. The facility has a large demand for telecommunication services necessary for the employees to communicate within the facility, \ place calls outside of the facility, while providing services to incarcerated inmate population. Residents of the facility maintain communication with family members accessing the phone systems and use video conferencing. The facility is newer and was built using the Voice over Internet Protocol known as VOIP running through a T1 line. The Voice over Internet Protocol is the means for the facility operate and maintain voice communication within the confines of the building while holding the capability to place calls anywhere outside. Due to the large amount of connections each office is set up with a phone connected using the VOIP. Each system is set up using an Ethernet cable connecting to the office phone and another cable running to the internet connection to the computer tower. A benefit to this system is once the phone is automatically set up the internet tracks and carry’s the phone number and extension number when a phone is relocated within the facility. The inmate population uses the VOIP system while housed in their living units. Their phones hold the appearance of a pay phone, but it is connected through the same VOIP service. The company is able to track, monitor, and record inmate phone conversations through the internet system. The same type of format is used when the inmate population conducts Video conferencing with their family and friends. The internet conferencing allows them to communicate through the VOIP
