A Traditional Class 4 Switch

More commonly known as a Tandem telephone switch, a class 4 connects class 5 switches to a larger network. It is a telephone central office switch used to connect the end offices of telephone service networks together. Class 4 switches can only deal with high-speed digital four-wire connections. Lucent and Nortel are the top manufacturers of equipment used for class 4 switches.

For VoIP providers, a Class 4 Softswitch can replicate what a traditional class 4 switch does for landline telephone calls. Colocation America provides a high performance VoIP server for the both carrier and enterprise markets capable of handling the installation of a Class 4 Softswitch. The softswitch secures the delivery of VoIP traffic or services over multiple IP networks and includes full component redundancy.

Types of Class 4 Switch

There are two types of connections for a class 4 switch. One is called a sector, or local tandem, which is used to interconnect to the traffic between class 5 switches within a local access and transport area (LATA). For example, a call is placed from California to New York. The call travels through the class 5 switches and find out that it cannot access the New York phone number through that network. It then connects to a class 4 switch which allows it to connect to another class 4 switch in New York. It then again connects to a class 5 switch in the local area the phone number is located to complete the call.

Another type of connection for a class 4 switch is called an access tandem switch. This is when a class 4 switch connects to a long-distance telephone company, also known as an Interexchange carrier (IXCs). Much like a local tandem, the same process is repeated but the call travels overseas through the point of presence (PoP) provided by an IXC. It then gains access to the class 4 switches in other countries and can interconnect to the one it needs to reach.
