Part A – Telecommunications Technologies
Question 1 – Private Branch Exchange (PBX)
a) Evolution of PBX
Private Branch Exchange is a phone system in business that has been designed to share lines and route calls. These systems basically contain the phone lines and the phone. A business with PBX setup can run faster, more easily and in low cost at it can handle both external and internal call volume. The PBX systems have evolved as three separate eras i.e. the switchbox, automatic and IP eras. Hamidi (2018) said that the first era was the switchbox that included owning a private operator for making calls in the early 1900s. The second era was the automatic era in which the need of an operator was eliminated and direct calls were made. In 1997, the third era emerged when phone calls were integrated with IP or internet. By the year 2008, 80% of the new PBX installations were using internet based phone services. Since then communication system is largely based on the internet services. 
b) Comprehensive analysis of current and emerging PBX systems in terms of reliability
PBX systems can be considered as a private telephone network that may be used within a company or an organisation. The users are able to communicate internally and externally in a quick and easy manner. The current PBX trends focused on the giving fast reachability to the people and a large number of people. The emerging trends in the PBX systems are the use of IP i.e. the internet allows to manage the calling systems more efficiently and allows more work to be finished. The emerging trend shave allowed people to grow in areas like voicemail, digital receptionists, etc. in terms of reliability, the older systems were more reliable. The data on the internet can be accessed or leaked using the right techniques. Thus it can be said that older systems were more reliable but th emerging systems can be made reliable with data protection services. 
c) Architecture of PBX systems
There are mainly three types of IP PBX architectures i.e. IP, hybrid IP, and Legacy Time Division Multiplier (TDM).
1) IP – In this type of architecture, the switching is done in the IP world and there is no transcoding between TDM and IP. The customers benefit from this system as they do not need extra hardware for digital signal processing. Example – 3Com, VCX, etc.
2) Hybrid IP – This system needs more resources for transcoding as the media is converted between IP and TDM. Example – Avaya Communications Manager, Nortel BCM. 
3) Legacy TDM Switch – these are the typically older systems and they give no worry of conversion of the media between the IP and the TDM bus. This is a TDM only type of solution. Example – Avaya Definity, Nortel Norstar. 
d) Compare and contrast different PBX systems in terms of costing
As mentioned earlier, one of the important reasons for adaptation of the IP PBX systems is the reduction of cost. The traditional phone lines cost so much more in national and international calls than the IP PBX. Another advantage is that there is no need to maintain hardware and system is highly scalable. There are three categories of IP phone system setups that cover most of the areas. 
Hosted IP PBX – in this system,
