Equipment

Phone Modem & Local Power Supply Unit

A phone modem, or Multimedia Terminal Adaptor (MTA), is a box that connects the cable and phone line inside your home. This piece of equipment is usually located in a basement, closet or office.

A Local Power Supply Unit (LPSU) can be used with an MTA to provide the power needed for your Spectrum Voice service. Alternatively, a single MTA can be used with a battery backup, to keep your service running in the event of a power outage.

Moving Spectrum Equipment

Spectrum Voice is a fixed-wire line service, designed to be used in the home in which the service is installed. The phone modem we install in your home is the property of Charter Communications. In the event you relocate or disconnect your Spectrum Voice service, you must return the MTA to a local Charter Spectrum store or arrange for it to be picked up by a Spectrum technician. If the device isn't returned, or it's lost, stolen or damaged prior to its return, you may be charged.

Purchasing Equipment

Customers with touch-tone phones won't need to purchase new equipment to use Spectrum Voice service. The service works with your existing phone wires, phones and wall jacks. We install a phone modem or MTA, which is used to communicate with our network. We charge a lease fee associated with the MTA that's included as part of the package price.

Phone Jacks

Spectrum Voice is a "whole house" service that uses existing phone wiring. This means that all working jacks in the home can be used.
