Just because you order a T1, Business xDSL, or even DS3 circuit, doesn't mean that the carrier will deliver the circuit to your business suite. The phone company is only responsible for getting the circuit to their demarc location in your building. In the case of leased circuits such as T1s and DS3s, our demarc extensions Indiana services are commonly required but often overlooked until the circuit is actually delivered.
What is a Demarc?
The word Demarc is short for Demarcation Point which is a catch all phrase for the more technical name called the Network Interface Device (NID). It is at this point where the phone company or "carrier's" network/wiring meets the customer's network/wiring. Most people could identify it at their home by the grayish color plastic box that hangs on the outside wall of their house as shown below (following picture is from broadbandreports.com)
In the residential realm, the network is typically already extended into the house so no additional work is needed. That is not always the case in the business world. As we go to setup clients in new locations or if we add a new service, our DSL setup Indiana technicians often have to extend the DSL circuit into the client's suite from a centralized demarc point in the building. If it is multi-story building or high-rise building, then our demarc extensions Indiana crews often extend the demarc up several floors and then into the clients suite. If the client is lucky, we can sometimes utilize existing wiring but even that requires additional time to tone and test the wiring.
Demarc extensions for T1 and DS3 circuits are the norm rather than the exception. Always budget at least an extra $250 for customer premise wiring/demarc extensions to be on the safe side when ordering a new T1 circuit. DS3 circuits can be a completely different ball game, so I'll go into them further in future articles.
The demarc point for a T1 circuit is called a SmartJack. The SmartJack device will typically be installed in a common Telco Equipment area within your building. An example of one is shown in the picture to the right. This picture shows four different SmartJack cards installed in the cabinet. A Cat5 cable can be plugged into the appropriate port at the bottom that corresponds with your particular T1 circuit. Standard Cat5 cable can be used to extend the demarc of several hundred feet, but for runs over 150' special programming of the T1 card in your router will be necessary. It is also good to note where the SmartJack is located in your building and to note which card is your circuit. There are red/amber/green warning lights on these cards that can warn of potential problems with the circuit.
Please note that the SmartJack cabinet as shown in the picture to the right, typically serves multiple tenants in your building. Only qualified persons should unplug cables from the SmartJack.
In instances where a T1 is delivered to a residential dwelling or a single unit business location, carriers may opt to install an outdoor SmartJack unit which serves as the demarc location. Our demarc extensions Indiana crews typically encounter these type of SmartJacks on clients who have T1s delivered to their home office or residential dwelling. The advantage to an outside SmartJack is that it allows for easy 24/7 access by the carrier's technicians. Our
demarc extensions Indiana crews typically utilize special UV protected and moisture resistant Cat5 cable when extending the demarc. Again it is good to note where the SmartJack for your T1 is located. Unfortunately, the outdoor SmartJack enclosures typically do not offer easily accessible observation windows for noting warning lights on the SmartJack card as does the indoor SmartJack option. If you are given the option of going with an indoor or outdoor SmartJack, I would recommend selecting the Indoor option. Access limitations can easily be overcome. The outdoor options brings into play another unpredictable element called weather which can reduce the reliability of your circuit.
The time to plan for a demarc extension is before the actual circuit order is placed. Our demarc extension Indiana crew will work with you estimate the associated costs of the demarc extension before the circuit order is placed. Proper planning for items like this can mitigate surprise costs the next time you order a new Internet circuit.
