All Internet service providers are required to post information regarding various issues so that consumers, both residential and business, can make informed choices about choosing an Internet service provider. This document contains information regarding our services and in compliance with the FCC’s rules. The policies contained herein serve as a supplement to the existing terms of service. More information can be found at:


Blocking: CMS does not
block lawful content, applications, services, or non-harmful devices or block consumers from accessing lawful Web sites. CMS does not block or de-prioritize applications that compete with the provider’s voice or video telephony services.

Discrimination: CMS does not discriminate in transmitting lawful network traffic over a consumer’s broadband Internet access service.


Paid Prioritization: CMS does not directly or indirectly prioritize or shape traffic to benefit an affiliate or for monetary consideration.

Congestion Management: Depending on service type, CMS subscribers share upstream and downstream bandwidth on the network. Disproportionate demand on the bandwidth has the potential to cause performance impacts. Congestion management may be applied when spam, viruses, denial of service attacks or other malicious activity is present. Congestion management techniques include limiting a particular connection’s bandwidth or shutting down a connection until the problem detected can be resolved. All users on the network receive equal access to bandwidth and CMS does not implement usage caps.

Application-Specific Behavior: CMS reserves the right to implement network management practices to prevent harmful or illegal activity such as virus distribution or transfer of illegal content. CMS currently restricts access to port 25 for outbound SMTP. Depending on the type of service and location, quality of service controls may be in place to provide consistent performance to real time voice and video traffic.

Device Attachment Rules: CMS permits any device as long as it does not harm the network or violate the acceptable use policy. Depending on the type of subscribed service, not all devices may be compatible. CMS may require CMS-owned equipment at the termination point of the customer location. Depending on the type of service and location, device registration and/or configuration of the device may be necessary to gain access.

Security: If CMS detects suspicious, criminal, or abusive traffic, or activity that violates our acceptable use policy we may temporarily block access to protect the security of the CMS network and its customers.  This may be triggered by a denial of service attack or by CMS detecting an unusual amount of traffic that may be related to computers infected with malicious software viruses.  If a customer believes that CMS is blocking such traffic in error, the customer should contact CMS Internet technical support at (800) 962-7022.
