The MT8733 includes two telephone ports that support standard (landline) telephones and other devices. The MT8733 is designed to work with Comcast Xfinity voice service only. To use the telephone ports, first, make sure you have subscribed to Xfinity voice service. This service may be provisioned to support either one phone line on TEL1 or two phone lines on both TEL1 and TEL2, with two different phone numbers. You can connect almost any standard telephone equipment to an MT8733 telephone port. This includes almost anything that connects using an RJ11 phone plug telephones, cordless phone base stations, answering machines, etc. (If you want to connect a security system, check with the security system manufacturer for compatibility). You can connect individual devices, or you can connect multiple devices that plug into the same phone line. (Their Ringer Equivalence Numbers need to add up to 5 or less.) One way to connect multiple devices is to plug the MT8733 phone port into a jack connected to existing telephone wiring. Before doing this, make sure to disconnect the wiring totally from the telephone company’s network demarc. This is normally done by unplugging a phone cord at the jack nearest to where the phone line comes into your home. After you unplug that phone cord, check that none of the phones on that line gets a dial tone when you go off-hook. If they don’t get a dial tone, it’s safe to connect a phone cord from one of the line’s jacks to an MT8733 phone jack. After you do that and power up the MT8733, all the phones on that line should get a dial tone. You may want to attach a cordless phone base station to the MT8733, and then place cordless handsets wherever you like. The Battery Purchase or Replacement section describes how you can make sure you have phone service even if your MT8733 loses power. What do the TEL1 and TEL2 light behaviors mean? TEL1 and TEL2 lights are green. Blinking: Establishing voice service OR Phone off hook/Call Active ON: Phone on-hook / Ready for calls OFF: Phone service not provisioned How do I make and Receive Calls? You can make and receive calls through connected telephone equipment just as you would with any other landline telephone service. Remember to dial 1 before long-distance calls within the United States. Check with Xfinity for international dialing. Where can I find additional troubleshooting steps?
