The telecommunications solutions we offer provide a clear channel for your phone system to operate, enhancing communication throughout your business.

  • T1

    Installing a T1 line into your business’s phone system allows your organization to carry up to 24 digital voice channels.

  • Primary Rate Interface (PRI)

    Similar to a T1 line, this solution delivers local and long distance phone service, as well as Direct Inward Dialing (DID) over one 4-wire interface.

  • Plain Old Telephone Service (POTS)

    POTS lines are the standard analog lines that provide local dial tone. They can be used for incoming and outgoing calls, facsimiles, modems, security systems, as well as credit card and ATM machines.

  • SIP Trunk

    SIP Trunking connects a company’s Private Branch Exchange (PBX) to the existing telephone system so the business can reap the benefits of a VoIP phone system.

Internet Access

Network Cabling Installation

In order to communicate effectively, a fast, reliable internet connection is a must. The Internet Service Providers (ISPs) we partner with offer a wide range of solutions to ensure your internet is never down.

  • T1

    A T1 line carries data at a guaranteed rate of 1.544 megabits per second! This reliable solution also protects your investment with a service level agreement.

  • Broadband Internet Access

    Broadband provides a fast and easy internet connection for a very affordable cost.

  • Digital Subscriber Line (DSL)

    DSL provides digital data transmission over local telephone network wires.

  • Wireless Internet Service Provider (WISP)

    WISPs provide hardware-free internet access in place of or with traditional ISPs.

WAN Accelerator

Wide Area Network (WAN) Accelerator

WAN accelerators enhance the speed of your connection, allowing for real-time collaboration for worldwide network users.

Virtual Private Network

Virtual Private Network (VPN)

VPNs transfer data between two or more networked systems on different private networks. This keeps the data private from other systems on intervening local or wide area networks, providing you with a secure form of communication throughout your organization.

Multiprotocol Label Switching

Multiprotocol Label Switching (MPLS)

MPLS provides multi-site to site connection throughout your business. Since all MPLS are not built the same, TCG will analyze your situation to determine which options are right for you.
