Small Business Setup with Spectrum

Small Business Setup with Spectrum

This is an example of internet with a few analog phone lines. Spectrum can deliver this service with fiber or coax, no matter how the service is delivered it is terminated on a modem/multiplex at the MPOE (minimum point of entry). Spectrum will usually have a modem of the internet and a spread modem/multiplex for the phone lines. At this location the customer will connect their internet and phone equipment to Spectrum's equipment. The customer’s router is connected to the modem. It should be noted that in some cases spectrum will provide a router and Wi-Fi Access point. The phone lines should be clearly marked by Spectrum so the customer can connect their new line to their phone equipment. When it comes to phone and internet service changes, ports and upgrades timing is everything. As a customer you should stay in communication with your account manager and phone/network vendor to avoid any downtime.

Small Office Network Setup

Small Office Network SetupBusiness network configurations vary from one business to the other but the basics remain the same.

An internet service provider deliveries service to an office. The provider can deliver service with many types of media including: fiber, coax, microwave, etc. No matter how the internet service provider deliveries the service once it reaches a business it is connected to a device so that a customer can connect their network to the internet. This device, that is provided by the internet service provider, can be a modem, circuit or in some cases a modem/router combination. After the modem/circuit has been installed and the internet “turned up” the customer can now connect their network equipment. The first set is to connect a router/firewall to the modem/circuit.  The router is the “brain” of a network. It is responsible for sending IP packets to and from the correct computer or device on the network. Arguably the router is most important component of a network. Larger more demanding networks require better preforming routers. The next step is to connect the switch(s). Network switches allows for multiple device and computers to be psychically connected to the network. In more advanced networks the switch can be used to logically and/or psychical segment the network.

Business Phone Service

Business Phone ServiceIt all starts with a phone service provider. Examples of a phone service provider include Verizon, AT&T and TimeWarner/Spectrum. Once a contract is signed the chosen phone service provider will deliver the service to a demarcation point. The demarcation point is the location on a property to where a phone service provider is responsible delivery of service. Examples: telephone box on the side of a building, telephone rooms and server rooms.

There are three types of phone service; Analog, Digital and IP:

  • Analog Phone Lines
    These are the oldest form of telephone line and are still in use. Now day these lines are not pure analog line because they transmitted/delivery not as analog but are only analog at the customers location (DEMARC). The reason for using analog today is simple...most phones and older phone systems are made to work with analog lines.
  • Digital Phone Lines
    Surprise…digital lines are digitized. This means that voice calls are converted to 1’s and 0’s which shrinks the amount of “space” needed to transport a conversation. This allows phone service provides to use existing telephone infrastructure while increasing the number of lines it can handle. These type of lines do require interface devices to connect the provider with the phone system. Examples include: Prime Rate Interface (PRI) and T1s.
  • IP Phone Lines
    Internet Protocol phone line are lines that are transmitted through the internet. Voice calls are broken down into IP packets and then sent back and forth across the world wide web. Then these packet reach their location (caller or receiver) they are reassemble back into voice calls. Some packets can be lost or delayed, this is what causes poor call quality at some sites. Phone systems that are capable of using IP phone lines have a network interface card (NIC). Example Include: SIP Trunks and IP Gateways.
