CALEA stands for the Communications Assistance for Law Enforcement act; a federally mandated law enforced by the Federal Communications Commission (FCC). This law requires that communications service providers assist law enforcement agencies #WHATISCALEAin executing lawfully authorized electronic surveillance, including live intercepts of voice and data packets from service providers.
CALEA Compliance FAQs
Federal law specifies that all telephone and data providers make available a means to execute surveillance on communications that flow through the provider’s network.
Minimum compliance means being able to execute ANY valid warrant for surveillance on ANY user on your network in a timely manner. Carriers must be able to provide both content of communication and communication-identifying information along with a correlation of those elements.

This must be accomplished while maintaining confidentiality, integrity, and authentication of the communication-identifying information. The term of law stated is that compliance is to be on a ‘best efforts’ basis.
There are three compliance options:
  1. Develop you own compliance solution for your network. 
    1. Can be complex and dependent on certain skill sets within your organization that may not always be available. 
  2. Purchase a compliance solution from a vendor 
    1. Purchasing a compliance hardware solution can be expensive and needs replaced as your network grows. 
  3. Purchase a compliance solution form a Trusted Third Party (TTP) 
    1. TP will help you decide best method for compliance. 
    2. Port mirroring to Probe or Equipment may have LI capabilities built in. 
You will be subject to fines of up to $10,000 a day (until you come into compliance) from the Courts. You are also subject to fines from the FCC as they have the enforcement responsibility for the CALEA mandate.

A Trusted Third Party (TTP) is an entity a carrier has allowed to implement their CALEA compliance program. The TTP can provision, implement, and maintain resources for the carrier. A TTP is recognized by the government as an entity that can act in behalf of the carrier to implement CALEA compliance while maintaining a certain level of indemnification.
You will receive a warrant from a law enforcement agency.

CALEA is not the Digital Millennium Copyright Act (DMCA). DMCA governs the illegal use of copyrighted materials, and potentially holds Communications Service Providers (CSP) liable when subscribers use material unlawfully. When those infringements occur, DMCA agencies send notices directly to CSPs, who are then responsible for passing those infringements along to the offending subscriber. CSPs can easily manage DMCA notices by themselves.
There is no evaluation or certification for CALEA compliance. Lack of ability to fulfill the request demonstrates a lack of compliance. Likewise, the provider’s ability to fulfill a warranted surveillance request demonstrates CALEA compliance. However, Nex-Tech prefers to conduct CALEA Customer reviews every year or two to discuss changes in the carrier’s network and to identify any obstacles that may complicate the Intercept process.
There is no evaluation or certification for CALEA compliance. The test rests in the provider’s ability to fulfill a warranted surveillance request.
Nex-Tech will provide the warrant validation, access, delivery, and collection functions required for your CALEA compliance. The burden of capturing the intercept and delivering the information to the appropriate law enforcement agency will rest on Nex-Tech’s lawful intercept platform. The burden of complying with the warrant still rests with your company.
Nex-Tech will be a partner in the provisioning of the customer’s CALEA compliance. Nex-Tech will endeavor to put forth the resources necessary to work with the customer to complete the required intercept requests.
The relationship of Trusted Third Party is one that is established between the carrier and Nex-Tech. By identifying Nex-Tech as a Trusted Third Party, your business gives Nex-Tech that status which will allow Nex-Tech to operate in your name for certain aspects of your CALEA process. There is no authority certifying any company as a certified Trusted Third Party. The title exists as the relationship is solidified between the carrier and Nex-Tech.
A warrant may originate from a number of entities that include local and state law enforcement agencies, federal law enforcement agencies, local and state prosecutors, the US Justice Department and other federal agencies. A valid warrant will have a judge’s signature.
Validating a warrant means being able to ascertain the signature is that of a judge in good standing. Nex-Tech has attorneys to validate the warrants.
Nex-Tech has the responsibility of collecting the data from the intercept and transmitting it to the appropriate law enforcement agencies. As our customer, you do not have to provide any means for law enforcement agencies to connect to your network.
As a carrier, you will be contacted. It is then your responsibility to contact Nex-Tech to implement the intercept.
According to the law, a carrier can be served a warrant at any time. While it is extremely rare for a warrant to come in after business hours, it is possible. Carriers need to plan for that.

The entire process can be summarized in four stages: Engineering, Installation, Warrants, and the Capture and Transmission of data to the LEA.

Nex-Tech will be happy to further explain this process over a short phone call.
The number of taps required will be determined after Nex-Tech has done a network assessment. Nex-Tech will seek out aggregation points in the customer’s network that can be used to collect the needed information. Every network is different, and Nex-Tech is going to be diligent in finding the solution that will effectively meet the customer’s CALEA needs.
Because every network is unique and different, Nex-Tech and the customer will analyze data to understand how the information flows through your particular network and develop a plan specific to your needs.
It varies. Keep in mind that law enforcement agencies wish to capture a complete copy of the target’s data or voice transmissions. For voice intercepts, the process is likely to consume less than 100 Kbps. Data stream intercepts will vary. For example, the slowest link in your network will impact the amount of bandwidth consumed by the surveillance process; however, we anticipate the bandwidth required to be minimal.
Nex-Tech will monitor the equipment; you will not have to allocate any manpower to perform such tasks.
The impact will be minimal. All your network is actually going to be responsible for is the direct transmission from the probe to our facility.
The security of your network is not going to be compromised by the equipment in place. For the purpose of data transmission from the probe to Nex-Tech, we will establish a secure IP VPN tunnel.
The probe will ‘listen’ for traffic that matches the warrant. Only information specified in the warrant will be replicated and sent back to our facility. There, a dedicated mediation server will package the information collected, and in turn, send it to the law enforcement agency who issued the warrant. No further action is required by you during this process.
The taps placed on your network pose no threat to security or the integrity of your network. There is no reason to isolate it through firewalls or any other means. It is meant to function inside your network to trap just that traffic which matches the configuration of the probe.
If communication is going to take place through a firewall, we recommend implementing a list that will identify and allow access by certain specific traffic. Nex-Tech will provide you with the IP addresses that will need access and the TCP/UDP ports that need to be open.
No. The probe and tap are designed with one purpose, collection of data returned to Nex-Tech for dissemination to law enforcement agencies. There is no added exposure for your network. Through the use of a VPN tunnel, the probe will communicate directly with Nex-Tech’s intercept platform.
