Types of switchboards and their functions

In the business communications market, three types of switchboards stand out: analogue, digital and IP PBX’s.

Analogue switchboard:



They are based on analog technology, calls are switched and redirected to the recipient through the electronics of this switchboard (small switches). Phones are usually simpler and connect with an RJ9 connector (two wires).

They use basic lines (RTB) for outdoor connection. Its price is cheaper with rather limited functionality, require outside physical line for each call.

Digital switchboard:

At present, most PBXs are of this type (digital). In a technical way it can be said that they are similar to a server (computer), the calls are managed transforming them to data (1 and 0s).

A switchboard has the ability to support several types of input lines (ISDN, RTB, GSM, fax, modem, among others).

The terminals to be connected must be digital (they are connected through an RJ11 or RJ 45 cable). They merit as well as analogical switchboard to have the wiring in the office.

IP switchboard:

IP PBXs are the most advanced and modern solution available. They are very similar to digital switchboards (they manage data with 1 and 0) their standard is IP communication (just like Internet data).

Thus, sharing office Internet networks (Ethernet) as well as external networks that connect everyone.

This system allows sharing Internet networks, including computers, through any Ethernet connection.

Why implement hybrid VoIP solutions?

There are many reasons to go from a traditional telephony (analog) to a digital (SIP, VoIP), we name below only three by which you should implement in your business.


  1. Investment


Tight budgets can make it difficult to make a complete infrastructure change when it comes to changing telephony altogether.

A granstream gateway can simultaneously connect analog phones and IP PBXs to deliver the benefits of SIP technology.



  1. Lack of availability


In some geographic regions the bandwidth is reduced, preventing to obtain a SIP connection to migrate completely to digital telephony.

With grandstream gateway you can build a 100% IP network internally and connect it to analog trunks.



  1. Massive deployments of analog telephony.


Many residential phones are based on analog technology and refuse to switch to digital technology.

Creating a smooth transition to allow users to continue using analog devices will be the best way to address this problem.

VoIP gateways work very easily, as the source of traffic is extremely necessary. A VoIP gateway not only converts the general phone into an Internet-based phone, but also digital IP packets into TDM technology. A protocol and a codec play an important role in the correct functioning of the gateway. However, compatibility is also one of the essential factors to consider.

Gateway Types

Normally there are two types of Gateway, the analog and the digital. Each has its own functions and benefits.

  • Analog: Connects traditional phone and VoIP phone system or VoIP phone and PSTN.
  • Digital: The connection between digital voice lines and VoIP telephony systems is made through digital gateways.
