Data & Voice Network Wiring

Fiber Optic

Choosing the right fiber optic cabling is important for networking solutions in Chicago, IL to assure your desired network speed and connectivity is achieved. Its far-reaching capabilities make fiber the perfect solution for large spaces such as warehouses or corporate offices or underground.

Our experienced communication electricians have superior product knowledge to provide the proper fiber optic network design. As a fiber optic cable installer of single or multimode fiber, we provide indoor and outdoor cabling and armored cabling as well as fiber optic cable testing, certification, and fiber optic cable termination (ST - SC - LC - MTRJ connectors).

Our services include complete rewiring, replacing/ upgrading voice and data cabling, adding new cable drops, fax lines and outlets, and clean up/removal of abandoned wiring per building code requirements.


There is an increasing demand for greater wireless capacity in wireless networking enabled buildings. Rapidly growing WIFI usage, insufficient wireless networks, and dead spots are addressed by IBC installers who take the time to understand your specific wireless concerns. We design and implement complete WiFi / Wireless network solutions by relocating, reconfiguring or adding to the wireless network. Proper wireless network installation includes strategically placing wireless access points to address both current and future wireless requirements. IBC runs wiring to the access point, mounts the access point enclosure hardware, and installs hardware so that the network can be programmed or configured.


When there is a need to connect multiple buildings with phone and data cable networks, installing underground PVC pipes is often necessary. This can be accomplished with traditional trenching if there are no obstacles between the buildings. If waterways, buildings, roadways or other structures prohibit trenching, then directional boring can be a good solution. Boring allows minimally invasive access to install the pipes without significantly disrupting the ground. IBC installs underground conduit with directional boring to house client cable or AT&T installed cable.

Because overhead cable can only be run a limited distance without support, IBC technicians may install a figure 8 cable for support. Satellite is another option when cable is needed to connect structures at further distances; however, satellite requires a direct line of sight. If there are no obstacles between the structures, IBC will provide the wiring for satellite.

Demarc Wiring

An understanding of Demarc Wiring will make the installation of new services go smoothly

Moving your offices into a new building? Upgrading or changing the telephone and Internet service in your office? Without a basic understanding of demarc extension, you could be in big trouble.

Changes like these create upheaval when it comes to your telephone and Internet service. Getting new phone service installed, upgrading the type of Internet service you have, or adding more lines takes some planning to make things go smoothly so you don’t disrupt service.

You probably think calling your phone or Internet service provider and asking for help with the change will take care of it. It’s not their responsibility to extend the service into your suite. If you don’t ask the right questions about who is handling the whole process, you might get stuck without service for a period of time. Can you imagine your office without telephone or internet service? How will that affect your productivity? To avoid that, you need to know about Demarc wiring. It’s where the process could fall apart if you don’t ask the right questions.

First, what is Demarc wiring? Every building has a Demarc. Also referred to as demark, DMARK or MPOE (minimum or main point of entry). According to Wikipedia, it is the point where your telephone or Internet service provider brings the service to your building, the point at which the public switched telephone network ends and connects with the customer's on-premises wiring. It is the dividing line which determines who is responsible for installation and maintenance of wiring and equipment—customer/subscriber, or telephone company/provider.

In buildings of all sizes, this point may not reside in a client’s space but instead in an area common to the building and other tenants. This can be fairly far in distance and may require new cable. So, the terms “Demarc extension” is the extension of service whether it is data or telephone, to the clients IT/Telco electrical wiring closet.

OK, but why should you care about this? Because often, your service provider will not extend your service beyond the Demarc. So when you call them to say I need to move our phone service to the new building on Jan. 1st unless you specifically ask to have service extended to your suite, they will leave your service at the Demarc point or make incorrect assumptions as to where your suite may be. This is where you’ll experience down time and scramble to find someone to extend it or go back to the service provider and they’ll dispatch a technician to return, at a later date and add an additional fee to extend your service. All this takes time, which you likely don’t have, and disrupts productivity.

That is why we suggest that you should consider hiring a Demarc extension company, like us. Especially if you are changing service providers which will require moving your phone lines/internet service from where it’s located now.

To make your technology transition go smoothly, give our Demarc extension company a call to look over your system first. We’d love it if you called us! We can tell you whether you need new or additional Demarc wiring from the Demarc point to your wiring closet or from the wiring closet to your offices.

We are happy to answer any questions you may have about your move or system upgrade, so give us a call at 630-860-2266.

Phone Systems / Installations

Business Phone Systems

You can rely on IBC to keep you connected. Updating business communications is essential in just about every industry. IBC has the experience and expertise to sell, design, install and replace the business phone system that will best meet your company's needs, from Digital and Hybrid to VoIP phone systems.

Key Systems

Traditional key telephone systems allow companies to manage their inbound calls by sharing voice lines across all employees and departments. Key systems are geared toward small and mid-sized business customers with up to 50 users in a single office location.

Hybrid Systems

Hybrid phone systems can be designed to be an all-IP solution, an all-digital solution or a combination of both. Hybrid systems offer the cost saving benefits of VoIP without having to invest in a costly pure IP infrastructure. A Hybrid system can work with existing infrastructures, or it can become a pure IP solution, an all-digital solution or a combination of both.

VOIP Systems

Voice Over Internet Protocol (VoIP), uses the Internet to make and receive telephone calls rather than using a conventional phone line. This type of phone system can be less than traditional phone systems, VoIP calls are often clearer, and long distance and local calls can be made through VoIP without incurring additional charges that would exist if you were using a conventional phone line. There are three main types of VoIP service technology that exist, and each type is slightly different.

House VoIP systems are used in businesses that have the money to purchase the phone system outright and set up and maintain it to handle all of the business needs. House VoIP systems require the purchase of the PBX router, as well as dedicated servers and Internet connections to handle all of the needs of the business and the telephone system. In a House VoIP system, the initial investment is more costly, because equipment must be purchased and set up, but the benefit over the long term is complete company control of the phone system and no monthly fees, as the equipment and service belong to the business.

Hosted VoIP is generally used for newer businesses with fewer resources that may also be uncertain as to their future phone needs or their growth. Hosted VoIP involves subscribing to a service that provides and maintains the phones and hosting equipment such as servers, and that charges a monthly or semi-annual fee based on usage or a predetermined contract period. Hosted VoIP has the advantage of future flexibility, but the disadvantage of a monthly payment and essentially leasing the equipment rather than owning it.

Hybrid VoIP is a distinctly different type of VoIP technology in that it allows the use of an existing conventional phone system in tandem with a VoIP system that can be used to reduce phone and data-transfer costs. Hybrid VoIP also allows companies to keep their existing conventional phone systems, which may have been installed at substantial cost to them, and which may still be functional but which are costing too much to use as a sole means of phone communication. Hybrid VoIP allows for maximum integration with legacy systems with minimal system disruption.
