When a traditional phone system and a PBX system are pitted against one another, which system is going to end up being the clear winner? Naturally, the PBX system. Why? It is because since PBX systems are a product of a higher iterations of technology, they not only provide a higher level of performance compared to different communication means, but they are also cheaper to set up and will not require a high maintenance cost to keep them working at their peak performing levels. However, cheaper costs and higher performance are not the only factors that business owners look for when purchasing something that will be a part of the daily operational activity of the organization. What they also look for are features; something that will provide them will less of a headache and increase overall productivity in the organization.

Here are some features of PBX and why businesses should move on to Integrated Services Digital Network (ISDN).

The role of PBX in an organization

  • To switch between telephone users and creating connections
  • To make sure the connection remains in place properly by keeping its resources
  • To properly end the connection when a user hangs up
  • To record the quantities, statistics and counters related to the calls

Given below are the practical uses of a PBX system that is used in an organization

  • Provide one single number that external callers can use to access all persons in a company
  • Automate call answering, but offering a menu of options from which a user can select to be directed to a specific extension or department
  • Allow the use of customized business greetings while answering calls
  • Provide system call management features
  • Record voice messages for any extension from an external caller
  • Transfer calls between internal extensions

In addition to all the aforementioned features, PBX systems also come with Integrated Services Digital Network or (ISDN) support. ISDN is a set of communication standards that allows for simultaneous transmission of voice, video, data, and other network services over the traditional circuits of the public switched telephone network or PSTN.

There are several advantages that ISDN holds compared to traditional telephones. They are given as follows:

1. Unmatched speeds

Unmatched Speeds

ISDN allows multiple channels of communication to be operated simultaneously through the same regular phone wiring used for analog lines. This change can only come about when the telephone company's switches can support digital connections. This upgrade allows a much higher data transfer rate than analog lines. In addition, an ISDN line takes about half the time to transfer data to the other end compared to an analog line. This thoroughly improves communication applications.

2. Multiple devices can be used

Multiple Devices Can Be Used

ISDN allows multiple devices to share a single line. It is also possible to combine different digital data sources and have that specific information routed to the proper destination. Since the lines are digital, it is easier to keep the noise and interference out while combining these signals, which end up degrading the communication type such as voice and video calls.

Compared to a regular modem, which is present in several organizations to make communication and takes 30-60 seconds to establish a connection; an ISDN call setup usually takes less than 2 seconds. Since this allows more and more calls to take place, which automatically increases productivity, ISDN supported communications will always be preferred over the traditional telephone systems.
