Figure 36 - SIM security settings - SIM PIN locked 2 3 Enter the PIN in the Current PIN field and then enter it again in the Confirm current PIN field to confirm the PIN. If you are placing the antenna in a remote, unattended location, you may wish to check the Remember PIN option. This feature allows the antenna to automatically send the PIN to the SIM each time the SIM asks for it (usually at power up). This enables the SIM to be PIN locked (to prevent unauthorised re-use of the SIM elsewhere), while still allowing the antenna to connect to the cellular service. 4 When this feature is enabled, the PIN you enter when setting the Remember PIN feature is encrypted and stored locally on the antenna. The next time the SIM asks the antenna for the PIN, the antenna decrypts the PIN and automatically sends it to the SIM without user intervention. 5 When this feature is disabled and the SIM is PIN locked and the PIN must be manually entered via the antennas configuration interface. In situations where the antenna will be unattended, this is not desirable. Note Select Remember PIN if you do not want to enter the PIN code each time the SIM is inserted. 6 Click the Save button.

To access the LAN configuration page, click on the Networking menu at the top of the screen, then click on the LAN menu on the left. Figure 42 LAN configuration settings The default IP of the LAN port is 192.168.1.1 with subnet mask 255.255.255.0. To change the IP address or Subnet mask, enter the new IP Address and/or Subnet mask and click the Save button. Note If you change the IP address, remember to reboot the antenna and enter the new IP address into your browser address bar. DNS masquerading DNS masquerading allows the antenna to proxy DNS requests from LAN clients to dynamically assigned DNS servers. When enabled, clients on the antennas LAN can then use the antenna as a DNS server without needing to know the dynamically assigned cellular network DNS servers. The DNS masquerading toggle key is OFF by default. With DNS masquerading OFF, the DHCP server hands out the upstream DNS server IP addresses to downstream clients directly, so that downstream clients send DNS requests directly to the upstream DNS servers without being proxied by the CFW-2182 antenna. CFW-2182 User Guide UG01233 v1.2 August 13, 2020 Casa Systems 2020 42 of 63 With DNS masquerading ON, the DHCP server embedded in the CFW-2182 antenna hands out its own IP address (e.g. 192.168.0.1) as the DNS server address to LAN clients. The downstream clients then send DNS requests to the CFW-2182 antenna which proxies them to the upstream DNS servers. You may also override the DNS Masquerading option by specifying custom DNS Server IP addresses in the DHCP Server configuration mentioned in the next section of this guide. In this case the DHCP server assigns downstream devices the manually configured addresses and the DNS Masquerading option is ignored. The DNS masquerading toggle key is OFF by default.

Remote management TR-069 The TR-069 (Technical Report 069) protocol is a technical specification also known as CPE WAN Management Protocol (CWMP). It is a framework for remote management and auto-configuration of end-user devices such as customer-premises equipment (CPE) and Auto Configuration Servers (ACS). It is particularly efficient in applying configuration updates across networks to multiple CPEs. TR-069 uses a bi-directional SOAP/HTTP-based protocol based on the application layer protocol and provides several benefits for the maintenance of a field of CPEs:

Simplifies the initial configuration of a device during installation Enables easy restoration of service after a factory reset or replacement of a faulty device Firmware and software version management Diagnostics and monitoring Note You must have your own compatible ACS infrastructure to use TR-069. To access and configure the TR-069 settings, you must be logged into the antenna with the root account. When a factory reset of the antenna is performed via TR-069, the TR-069 settings are preserved. The NetComm Wireless antenna sends inform messages periodically to alert the ACS server that it is ready. These inform messages can also be configured to accept a connection request from the ACS server. When a connection is established, any tasks queued on the ACS server are executed. These tasks may be value retrieval or changes and firmware upgrades.

FCC has authorized the full use of the CBRS band for wireless service provider commercialization under a three-tiered spectrum authorization framework to accommodate a variety of commercial uses on a shared basis with incumbent federal and non-federal users. With this service, wireless carriers using CBRS are able to deploy 5G mobile networks without having to acquire spectrum licenses. When devices such as your CFW-2182 want to use the CBRS band they put in a request to a cloud-based Spectrum Access System (SAS) to reserve unused General Authorized Access channels in a particular geographic area. If channels are free, SAS can grant the requests. When devices with permission to use channels no longer require access, their unused authorization is put back into the pool that the SAS draws from to grant requests to other users with minimal interference.
