Mulberry Telecommunications provides broadband Internet access service. We currently have several service plans from our entry level, 512k download, to 10Meg download. Although we make a best effort to provide the subscribed speeds, we DO NOT GUARENTEE that you will receive the speeds at all times. Without subscribing to a dedicated and expensive Internet connection, no ISP will and can guarentee particular speeds to a customer. Mulberry Telecommunications advertises its speeds, up to your subscribed service plan.

The "actual" speed that you will experience depends on a variety of conditions, many of which are beyond our control. Examples of things that may affect your Internet speeds: The combination of services subscribed to. If you have our video and internet service, and bandwidth is limited, we will give the video services the bandwidth required by reducing, if needed, your broadband/internet speed.

Performance of your computer including its CPU speeds, available memory, running applications (including antivirus/firewall applications), operating system, and presence of any spyware, viruses or trojans.

Your local network including cabling, routers/wireless routers and other networked devices.

The site/IP address of your destination. Mulberry Telecommunications does not have control of the entire Internet, only our network. Traffic beyond our network is out of our control. Congestion or high usage is typical at popular websites at peak times. If your destination does not have sufficient resources or they limit speeds from visitors, these limitations will carry through to your connection to them.

Results from Broadband speed test typically found on the internet vary from site to site and test to test. These are just an estimation at that particular time. Broadband speed test work by sending you a file of a specific size. Your PC normally uses an html embedded java/javascript to time how long it takes to get the file. It calculates the approximate speed of the download by the file size and time it took. The smaller the file and other conditions, like those listed above, make small fluctuations in timing will make the results vary greatly.

Blocked ports. Internet ports were designed to carry various services over TCP/IP. Each "service" uses a different port, i.e. WWW is 80, sending Email is 25, receiving Email is 110. Ports numbered under 1024 are considered privileged ports reserved for documented applications. Some services use ports that are not intended to be reachable across the Internet. Some services, if the ports are exposed, can potentially provide a means by which someone can gain access to your Internet devices. In addition, a programming bug in the software that runs certain services may also provide means by which someone can gain partial or full access to your connected devices. Certain ports, for your protection, are blocked by us. Listed are the ports blocked. We monitor our network and if we see unusual traffic that clearly is an attempt to disrupt service to our customers, including traffic coming from one of our customers, we may block it.

IP Address:,, These are private IP space that is not permitted on the public networks. Forged packets from the outside, in an attempt to hide the real originating IPs, are common. They are blocked.

TCP/UDP Port 135-139: Microsoft's DCOM/NetBIOS ports. Known exploits and security risks.
TCP/UDP Port 445: Microsoft Active Directory, file shares. Known Exploits and security risks. Potentially can allow "attacker' to gain access to your PC.
