How Does a PBX System Connect to the world?

PBX systems are the heart of any successful business. Communication is an important factor in building customer relationships and conducting day-to-day business. Without efficient work phone system, business could lose revenue as well as customer confidence.

Phone systems are designed to handle the call volume that exceeds what one would normally see at home. Since many calls are coming in at the same time, the phone system is necessary to route these calls to the appropriate party where the customer does not hear a busy signal. This is done by using paths or multiple phone lines that are connected to your system. Based on call volumes, these “phone lines” can either be an ISDN line, or may be a series of single lines. Selection of the circuit is largely dependent on the expected call volumes and budget business owner.

In the case of smaller companies, using many individual lines might make more sense. While some may be surprised to find that the cost of a single ISDN circuit could be cheaper than constantly adding phone lines to keep up with demand. This is where the projected growth in mind when ordering circuits or phone lines. This is especially true in cases where rapid growth is expected.

Please refer to the circuit, ISDN is a type of “telephone line” which has 24 channels with one channel taken for data such as rings. The remaining 23 channels can carry one call each simultaneously. This solution would work better than the 23 individual phone lines to accommodate incoming and outgoing calls. These paths can be set up in the PBX system to allow incoming or outgoing calls or a combination of both. In addition, depending on the operator used, they can be specified for either local or long distance. In most cases, they will be put up for Least Cost Routing. You might be able to send both local and long distance calls in the same circuit, but it might not be cost-effective to do so.

ISDN T1, or cycle, are suitable for larger companies with high expected call volume. These paths are generally in call center environments that have more technology to route calls to agents. For companies that have a very high call volume, a DS3 is often used consisting of 28 T1 or individual circuit. This allows for a greater amount of call volume and could be more cost effective solution than ordering 28 individual T1. The cost of a DS3 depending on the distance from business location to the end of the carrier network. This is why it is a good idea to shop around when considering purchasing a DS3 for communications. This way you can choose the carrier that has the shortest distance to minimize costs.

Another solution that is rapidly growing in popularity because of its versatility and cost saving VoIP. Unlike the relationship described above, VoIP technology sent conversation with IP technology in much the same way that computers transfer data. Since both voice and data can reside on the same cycle, the need for the number of cycles can be minimized. Because VoIP converts conversation data packets, it is important that the voice data does not conflict with the normal transmission of data as seen when transferring files or sending emails. This is because the voice data must be received in the order it is sent. If the end of the conversation gets to the destination before the start, the conversation will not be understandable. In the case of data transmission, if there is a bottleneck, the network will simply begin sending data again once the bottleneck clears.

The conversations are real time, this will not work for voice traffic. This is why it is important to have the correct settings in place to ensure that the voice conversation has the highest priority. The number of calls that could run concurrently would largely depend on the size of the network, data cycle and how much other data would be sent on the same circuit. In addition, the network configuration plays a big role in the quality of sound during a call. VoIP is appropriate for large and small businesses because of its flexibility. Depending on the needs of the business, bandwidth can be moved up or down and allow business to exploit the network to route calls.

There are many solutions when it comes to connect the PBX system to the world. Differences in cost and capacity, each solution has its benefits and drawbacks depending on customer need. It is also the deciding factor PBX itself. Knowing what is compatible with PBX as well as expected call volumes will go a long way in making the appropriate choice of communication to meet business needs.
