Values are updated according to the screen refresh rate. Figure 19: Web: Monitoring - Status - Wireless Status Screen Wireless Status CINR [dB]: Mean Carrier/(Interference + Noise) ratio. The CINR value is calculated and displayed for each automatic screen refresh. The CINR measured by the base station is based on the signal from the subscriber. Based on this value, the base station may request that the subscriber change modulation rate. Traffic Downlink [kbps]: Rate of traffic transmitted to subscribers. BW Margin Downlink [kbps]: Downlink bandwidth available that can be scheduled by the base station (based on the minimum traffic rate settings for all active service flows). CRC Errors: Number of CRC errors detected on packets received from subscribers. This counter is reset when the base station is rebooted. Note: The CRC Errors counter in the SS Info screen is reset when a subscriber is registered. Air Interface Status: Status of the base station modem: Enabled - Transceiver is operating normally. Disabled - Transceiver is disconnected, disabled, or defective. IDU Temperature [Celsius]: Internal temperature of the indoor terminal. Power Supply Status: Display the status of the power circuits. A-On - Terminal is equipped with AC circuits only. D-On - Terminal is equipped with DC circuits only. A-D - Terminal is equipped with AC and DC circuits. Active DL Service Flows: Number of currently active downlink service flows. DL SMC Rate [kbps]: Data rate for SMC channel. DL Bandwidth Usage [%]: Current usage of downlink channel. Reference RSS [dBm]: The Reference RSS setting is the target value for average Received Signal Strength (RSS) for subscribers RF signals received by the base station.](https://usermanual.wiki/Redline-Communications/AN100UXA.User-manual/User-Guide-937402-Page-38.png)

The suggested default setting for the Reference RSS value is: Channel Size Initial Setting 3.5 MHz -75 dBm 7.0 MHz -72 dBm These are the suggested initial settings; adjustments to this target value must be made based on the individual RF characteristics of each deployed sector. The RSSI value (dBm) for each subscriber can be monitored using the base station SS Info screen (Web interface). Tx power adjustments are based on a number of factors, and differences of up to 7 dB may be observed between the Reference RSS setting and measured RSSI. RF Tx Power [dBm]: Radio transmission output power level. Traffic Uplink [kbps]: Rate of traffic received from subscribers. BW Margin Uplink [kbps]: Uplink bandwidth available that can be scheduled by the base station (based on the minimum traffic rate settings for all active service flows). Registered SS's: Number of subscribers currently registered with the base station. SC Synchro Status: Status of the base station time synchronization. Refer to the RedMAX Base Station Installation Guidelines for complete details of the synchronization feature. No Synchro - Base station is not using synchronization. Master with GPS Synchro - Base station is Master and is synchronized to an external GPS clock. Master - Base station is Master and is using internal clock. Slave - Base station is Slave. Backup Master - Base station is Backup Master and will assume Master operations if Master is unavailable. ODU Temperature [Celsius]: Internal temperature of the modem.

For authentication the devices use X.509 digital certificates [IETF RFC 3280] together with RSA public-key encryption algorithm. At the end of the authentication, process the device has a shared key with its peer known as AK (Authentication Key). This Key is used to derive the TEK. Management messages between base station and subscriber modem are protected with a HMAC digest that ensures the data was not altered over the air in any way. The authenticity of the CA's signature, and whether the CA can be trusted, can be determined by examining its certificate in turn. This chain must however end somewhere, and it does so at the root certificate, so called as it is at the root of a tree structure. Root certificates are implicitly trusted. Redline Root CA certificate is issued by Verisign. It can be uses to validate the certificates of the subscriber modem and cannot be used to validate the certificates supplied by another vendor. Authentication Using Digital Certificates The entire authentication process is performed inside the base station and it does not require external AAA servers (e.g. RADIUS, TACCACS, LDAP, etc). Sixty-four Kilobytes (64 KB) of memory is reserved for X509 Root CA certificates. A root certificate allows the validation of subscriber modem certificates. Validation process implies a check of the certificates against the information stored on the base station. The result of this check is a truth value based on which the base station will allow the subscriber to join the network. There are two scenarios: 1. Base station can skip the validation of the certificates sent from subscriber and performs only a basic test to ensure is properly encoded. 2. Base station checks the digital signature with the information stored on the board. To switch between the two scenarios the operator modifies the field TrustAll under "privacy" group. 6.2.2 Configuring Privacy This section describes the CLI commands for Privacy sublayer functions. Settings for privacy modules are defined under "privacy" group. The values set by the user are taken into account only after a system reboot, even though the values are stored into NVRAM memory immediately. The privacy module on the base station always running, while the subscriber modem can be enabled or disabled. X509 Root CA Certificates Each subscriber modem shipped from the factory comes with two X509 certificates - subscriber modem certificate and CA certificate. The subscriber modem certificate is unique per subscriber modem sends the certificates to the base station during network entry procedure in order to authenticate itself. The base station verifies the certificates are valid and allows or denies the subscriber request to join the network. Base Station Privacy Settings The AK lifetime specifies the period the subscriber is authenticated with the base station, and TEK specifies the period the traffic key is valid. Changes to these parameters require a reboot. The two keys are replaced at regular time intervals as specified by their corresponding lifetimes. The operator can also specify to trust all subscriber certificates or to validate each subscriber based on stored root certificates. There are two modes: Operational Mode: The base station uses the 802.16 standard default values. Test Mode: Used only for testing the standard certification process.](https://usermanual.wiki/Redline-Communications/AN100UXA.User-manual/User-Guide-937402-Page-93.png)

Refer to section 3: Physical Description on page 24. 7.3.2 Console Port The front panel includes the Console port. Use the CLI commands to interrogate the base station status and program most system settings. 7.3.3 System Reset Switch Throughout this section, reference is made to the reset switch, which is a micro-switch recessed in the front panel in the system block. Use a small narrow object, such as a paper clip, to access the switch. Depressing the reset switch for less than five seconds activates a short-reset (equivalent to power-cycle). Statistical values are reset. Depressing the front panel reset switch for more than five seconds activates a long-reset. A long-reset reloads the factory defaults for the IP Address, IP subnet mask, password, and statistical values are reset. 7.4 Detecting Channel Interference at Startup Following a power-cycle or reboot, the base station monitors the RF Channel to detect interference on the uplink channel. The transceiver is set to receive mode and the PHY is programmed to receive a long preamble from a WiMAX base station. If no preamble is detected during the one-second interval, the channel is considered free of interference from other WiMAX equipment. If a long preamble is received, the base station continues to monitors the channel for an additional three seconds. If an 802.16d DL-Map is received, the following message will be entered into the event log: WARNING: RF Channel Conflict with [BS Id] This message in the event log indicates that another base station has been detected using the following RF-PHY characteristics: - Same DL channel frequency as the UL channel frequency of this SC - Same Cyclic Prefix - Same channel size (i.e., 7 MHz) If a long preamble was received, but no DL-Map was detected, the following message will be entered into the event log: WARNING: Unknown Interference was detected on the UL channel This second message does not necessarily indicate interference from another base station, and may be the result of cross-interference from subscribe stations.](https://usermanual.wiki/Redline-Communications/AN100UXA.User-manual/User-Guide-937402-Page-100.png)
