Manual for Installation of Voice over the Internet Protocol (VoIP)
Manual for Installation of Voice over the Internet Protocol (VoIP)
Arris TM502G Phone/EMTA Modem.
The following manual can be used to set up “VoIP” in each of the following system: ATT VoIP, Xfinity VoIP. Also, it could be used in any type of device that uses the technology (Voice over Internet Protocol) and has a phone line available. The installation requires a medium level of expertise and understanding of telephone wiring to complete this task.
Failure to follow each of the steps; might result in an unsuccessful activation of your phone service. In the case of alarm set up, it could result in the creation of an isolation network where you alarm system is completely disconnected from the telephone network.
What is VoIP?
VOIP is an acronym of the phone service identified as “Voice over Internet Protocol”. (Communications technology for carrying voice telephone traffic over data network such as the Internet. VoIP uses the Internet Protocol (IP)-one half of the Transmission Control Protocol (TCP/IP), a global addressing system for sending and receiving packets of data over the Internet.
works by converting sound into a digital signal, which is then sent over a data network such as the Internet. The conversion is done by a device, such as a personal computer (PC) or special phone, that has a high-speed, or broadband, Internet connection. The digital signal is routed through the network to its destination, where a second device converts the signal back to sound. Because of the digital nature of , call quality is normally much higher than that of a standard telephone. Another advantage is that frequently costs less than standard telephone and long-distance service.) VoIP. (2014). In Encyclopaedia Britannica
What is EMTA?
EMTA is an acronym to the term “Embedded Multimedia Terminal Adapter”. This is a combination of cable modem and telephone adapter.
Glossary of Terms:
The following types of wires are currently found in old and new constructions and their proper identification is necessary to properly connect them:
Cat3: Heavily used in the 90’s for wiring homes and offices. As a result it is still present in old homes.
Cat5: Their usage commenced around the year 2000. It is the standard cable used in offices and homes.
Illustration of how to connect cat5 to cat3.
NID: Acronym for “Network Interface Device”. It is always located next to your power line meter equipment.
Scotch lock (use to connect and splice phone wires).
Network Interface Device (also referred to as EBM by technicians).
RJ11 Modular Single Port Surface Mount Jack.
List of required tools/equipment:
· EMTA (embedded multimedia terminal adapter) Modem with line1 for dial tone services
· 1 Box Cat-5e
· 1 3M scotch lock hand crimping tool with step jaws and long nose /crimping pliers
· 1 Wire striper
· 1 Flat #1 screw driver
· 1 Phillip #1 screw driver
· 1 Professional scissors for wires
· Tone generator line tracer tester tone with amplifier probe kit
· But-set and a modular adapter
Fig 1 Homerun feed (preferred inside wiring (IW) phone network connection)
· Connect the EMTA to the signal and power up.
· Wait for all the light to be on, wait for line 1 to be on.
· Plug the but-set on line1 located behind the EMTA.
· Check and wait for the dial tone behind the EMTA or gateway
· Activate dial tone by calling the IVR 1-800 number.
· Check dial tone with your but set. (If no dial tone; continue to troubleshooting guide).
· Run test by calling in/out from the EMTA or gateway.
· If test went successfully continue with the following step below.
· Here you can have two different ways to finish the installation (simple telephone network installation: base phone set straight connect to the EMTA and its station base around the house) or (advanced network: following the procedure that will continue next).
· Run a cat5 wire from the room located the EMTA to the NID.
· If no phone jack present. Install an rj11 jack and connect the blue wire to the new jack.
· Connect the new jack to the EMTA using an RJ11 Modular Telephone cable.
· Go to the NID and disconnect the NID from external cable (ASW) to isolate the phone network only to the inside network. (Fig 3 y 4)
· Disconnect the ASW from the EBM and use the wire from the EBM (green /red) to connect to the cat5 (blue and white blue) refer to fig 6.
· Connect all jacks that you wish to activate to the EBM (EBM hold up to four lines) Fig 4. For more lines to be activated follow the tutorial of “how to splice and connect IW using schlock “refer to fig 5.

(Fig 6) Identification of most common part inside the NID.
· Connect the test phone in each phone jack and check for dial tone.
· Run test by calling in/out for each phone number.
· While calling, listen for static, noise in the line, delay in the call, gap in the voice, dropping call, or ring too low or almost impossible to hear. (If one of these problem appear on the phone service. Refer to troubleshooting guide technician to aim for a better resolution).
Two-wire copper circuits did not solve all the problems of long-distance telephony, however. As the number of lines grew, interference (or cross talk) from adjacent lines on the same crossarm of telephone pole became significant. It was found that transposing the wires by twisting them at specified intervals canceled the cross talk. ) telephone. (2014). In Encyclopaedia Britannica.
If alarm is present. Follow next steps
Today’s technology makes it easy for a non-expert to do the installation. Leader Security Companies are now using GSM Modules that connect their systems to cellular antennas to communicate with cell towers over wireless networks such as our cellular phones. That makes it a very independent system capable of receiving updates, proper calibration and call for emergency services; this type of technology does not need a landline as it used to need in the past. Also, it has a very reliable connectivity that is worth of its price (fig 7). However, there are cases when the expert is needed to proper wired an old alarm system.
(Fig 7) GSM Module for Alarm System (it eliminates the need of a land-line requirements)
Old system alarm work with plain line telephone service and they need to receive a dial tone in order to communicate with the emergency system such as 911 or police department.
So, this is our job. Make sure the alarm system has dial tone after a successful VoIP installation. This job is normally done by an alarm technician who has previously run the cable and leaves everything connected and working. In the other hand after we take over from another phone provider, we as technicians have to guarantee that all services remain as we found them before our visit. Additionally, it is very important to know the compatibility of this alarm with our new phone service. And further questions are needed to properly proceed with our installation.
Instructions for Wiring an Alarm Panel with VoIP.
· Identify the wire that goes to the alarm panel by a tone/searching method. If no wiring existing or bad wire preexist. Follow the guide to proper wire the alarm panel.
· Create a back feed this way (send dial tone to the rj31x using the cat3 green/red wires or the cat5 blue/white blue wires).
· Connect to the tips 4 and 5 in the rj31x matching the picture below.
· Take the second pair of wires to return the dial tone back to the NID.
· Connect the following color black/yellow from the cat3 or orange/white orange from the cat5 to the tips 1 and 8 from the rj31x. Refer to fig 7, 8, and 11
