Product Description The DH7S Signal Booster Series are dual band channel selective Public Safety 700 and Public Safety 800 Dual Band Digital Signal Booster that operates in the PS700 and PS800 bands. Each band has separate filtering modules, so no interference can be produced between the two systems. Each band has a separate To Base RF Port, so each band can have its own directional antenna. In the case the PS700 and PS800 donor Base Stations are located in the same donor site, a conventional splitter/combiner can be used to feed both systems with one same donor antenna. The connectors and LED panel in the cabinet are labelled as Band I and Band II, in this case, Band I is PS700 and Band II is PS800. BAND I  PS700 BAND II  PS800 Each band has a separate intermediate filtering. The intermediate filtering is done using FPGA based Digital Signal Processing that, among many, has the following features:  High Selectivity vs Low Delay  AGC per channel and per time slot  Squelch per channel and per time slot  Integrated Spectrum Analyzer This Signal Booster is capable of handling 30 filters in uplink PS700, 30 filters in downlink PS700, 32 filters in uplink PS800 and 32 filters in downlink PS800, making a total count of 124 filters. The center frequency and BW of each one of the filters can be tuned via a software interface. This Digital Signal Booster is intended to be used in P25Ph1, P25Ph2, TETRA, DMR, Mototrbo and Conventional radio systems. This Digital Signal Booster has a heavy duty IP67/NEMA4X cabinet for outdoor usage, it is designed to be wall or pole mounted. For more details refer to the product datasheet.

There is a dedicated port for this purpose, and a dedicated DC connector labelled “VDC IN” located inside the cabinet. Please check appropriate DC voltage at Signal Booster specification sheet. E. NFPA Dry Contacts: there is a dedicated cable gland for this purpose. A multi-conductor cable can be used to connect the NFPA dry contacts to the Fire Department Control Box.
Figure: NFPA Dry Contact connection location inside the cabinet F. Once the Signal Booster is connected to the power source, it takes about 40 seconds to run a booting routine. After that time, the Signal Booster is ready to be connected via USB cable to a computer running Fiplex Control Software (FCS) to be properly configured. The Signal Booster has two USB Ports, one for PS800 and one for PS700.
Starting Operation BE SURE THAT “TO MOBILE” AND “TO BASE” PORTS ARE PROPERLY LOADED EITHER WITH 50 OHMS DUMMY LOADS, OR RADIATING SYSTEM. The Digital Signal Booster may come in one out of two versions: a 32 narrow-band filters version or an up-to-8 adjustable-bandwidth filters version. It is even possible to have both versions in one device so that the user can choose either of them. Depending on which version is actually running, the main screen of the Fiplex Control Software will have a slightly different look. 1. Turn on the Digital Signal Booster, connect computer to Signal Booster through USB cable, and run Fiplex Control Software. It is recommend to turn off the power amplifiers. PA OFF in narrow-band version PA OFF in adjustable bandwidth version
2. Setup desired channel frequencies. Since Fiplex Signal Booster is channel selective, user has to know what frequencies are used in base station. Program frequencies and bandwidths Narrow-band filter frequency settings Program frequencies and bandwidths Frequency and Bandwidth settings
3. Turn on UL and DL power amplifiers, and check that any alarm indicator is active. TURN ON POWER AMPLIFIERSPA ON in narrow band version TURN ON POWER AMPLIFIERSPA ON in adjustable bandwidth version 4. Setup desired operating gain using FCS. UL and DL chain are independent, so both values must be set. To set DL band gain is recommended that AGC works around 3dB in each channel, in this way, maximum output power is achieved. 5. Set up squelch settings. Controls are independent in UL and DL bands. Typical values for UL are -110dBm for squelch threshold. For DL, recommended value for squelch threshold is minimum level received in any active channel minus 10dB.
Squelch, gain and power settings: narrow band Squelch, gain and power settings: adjustable bandwidth 6. For narrow band filters version, setup desired filter bandwidth, depending on presence of adjacent channels. In principle, recommended bandwidth filter is 90KHz due to its low delay, but if adjacent signal is detected, narrow filters can be used. Spectrum analyzer of FCS can be used to know rejection to undesired signals. It is recommend that adjacent channels output power be, at least, 10dBc lower than useful carrier.
PROGRAM FILTER BANDWIDTH Filter bandwidth selection for narrow band filters version Next figures, shows how integrated spectrum analyzer can help to select bandwidth filters: Poorly rejected adjacent channel with 90KHz filter Adjacent channel rejection with 90KHz filter
Rejected adjacent channel with 20KHz filter Adjacent channel rejection with 20KHz filter Status Indicators There is an indicator panel located at bottom of the Signal Boosters. This LED panel works as a status monitor, in order indicate warning or alarms of Signal Booster. The LED panel has four LEDs, the first one the power ON indication led, labelled “PWR”. The Second LED, labelled “STS” summarizes warnings regarding critical operational conditions of the Signal Booster. The third and fourth LED summarizes operational conditions for uplink “UL” and downlink “DL” chains. In general, the LEDs have four states: “off”, “slow blinking”, “fast blinking” and “on”. Next table describes alarm and warning conditions for each led state.

Initial window for adjustable bandwidth filters version Initial window for dual firmware version
Remote Web Server option IP Connection Fiplex Signal Boosters use an Ethernet module and 3G Router to give TCP/IP connectivity (webserver and SNMP Agent). In local mode, user can connect directly a computer to the Ethernet module using the inside Ethernet cable. In order to access to web browser, default IP addresses of Ethernet module are detailed in the next table: IP Address 192.168.1.10 IP Address Network submask 255.255.255.0 Network submask Gateway 192.168.1.2 Gateway Computer network adapter configuration needs to be set to same network submask and gateway. IP address can take any value in this IP range (192.168.1.11, for instance). These addresses can be changed by user. Web pages description Once the Ethernet module is properly configured, user can connect to the Signal Booster, writing IP address in URL toolbar of any web browser available in its computer. Default URL is http://192.168.1.10. First screen to appear is Authentication. Default login and password are: Login admin Login Password admin Password Password can be changed by user, using menu described in next sections. NOTE: in order to restore password, push the button placed close to USB Connector during 5 seconds.
After authentication, web browser will load the main page of Fiplex Signal Booster showing RF configuration and monitoring parameters. At left side of webpage, configuration menus are shown: Content  Status: whole RF configuration and monitoring parameters are shown. These parameters are described in the next section.  Tag: user can set a tag to ease Signal Booster identification. For modifying the TAG, write a new value in text field and click over Apply Changes link  IP: At this page, Signal Booster IP address, network submask, gateway address and IP addresses of SNMP Managers are shown. User can set addresses of two SNMP Managers (IP where SNMP agent will send TRAP information). To modify, click over Apply Changes link after writing new values on text fields.
In case the Signal Booster had been fit with an internal modem-router, its own IP address settings would be fixed and the modem's address would be shown in the greyed boxes.  Spectrum: this page shows estimation for input and output spectrum in either DL or UL, whatever is selected by the user. Estimation for output spectrum takes into account RF input levels, and gain, bandwidth filters and squelch options programmed by the user, and it can be a useful tool for users to know how the undesired signals are rejected by the channel selective Signal Booster. The user can change start and stop frequency modifying text fields placed at the page bottom. Minimum span is 200KHz and maximum span is the band covered by the Signal Booster. In case the same frequency is set for both start and stop, then zero-span is set. For user convenience, a zero-span checkbox is available that makes that operation with one click, and chooses the start frequency setting as the measurement frequency. That also disables the stop frequency setting and changes it according to start frequency. And finally, measurements can be averaged up to 32 times.
 Date and Time: page to modify real time clock. When the Signal Booster is not powered, this clock runs with a voltage supply provided by a 3V lithium battery, button type of 20mm (CR2032) with 220mA·h. This suffices for at least half year. When the Signal Booster is powered, no current is drained from the battery. So, actual battery life will depend on Signal Booster usage. For battery replacement, please locate battery holder between USB and Ethernet connectors on main board. Battery positive side is UP, i.e. on holder clip. Date and time setting After clicking on “Apply Changes” link, next message will appear, warning the user that system needs to be rebooted.
 Filter Info: following this link, a new window appears with detailed information of frequency and delay response of all available filter bandwidths (1dB, 3dB and 10dB bandwidths and delay at center frequency)  Filter tool: assistant to easily configure signal booster filters with minimum delay response (all filters set to 90KHz bandwidth). It is especially useful if carriers are grouped in “frequency packets” where it is not possible to configure an independent filter for each one. With this tool filtering parameters are automatically set from a desired frequency carriers list. This tool executes in a pop-up window as the image below and is described in next sections:
The desired carrier frequencies of the downlink band, are to be typed in the text area of this window expressed in MHz. The tool will try to enable as many filters of 90KHz bandwidth as necessary for all carriers, using a fine gain of 0dB by default. This is trivial when carrier frequencies are sufficiently separated apart. For instance: The button "Compute Configuration Proposal" shows the computed filter frequencies in another text area and, if accepted, the button "Apply Proposal" would actually perform the configuration change. However, for carrier frequencies that come in packets, the filter frequencies should not be set too close because the overall response would be distorted. Depending upon signal modulation, that response distortion might not have any
consequence. But in the case that distortion cannot be tolerated, consider that the minimum frequency separation between two filters to avoid this problem is 1.25 times the semi-sum of their bandwidths. For instance, two filters width bandwidths 90KHz and 30KHz respectively, must be separated apart by 1.25·(90 + 30) / 2 = 75 KHz. Nevertheless, there are certain conditions under which filters can be set closer to make up a single filter with wider bandwidth: o The frequency separation must be 93.75 KHz. o All of them must have the same bandwidth setting of 90 KHz. o All of them must have the same fine gain setting. The Filter Info window shows the frequency response of the combination of up to five filters:
Now, consider for instance a case with the following downlink carrier frequencies: 392.0, 392.05, 392.1, 392.15, 392.2, 393.0 and 394.0 MHz. This is when the Filter Tool comes in handy. It will automatically choose the filters required to cover the range between 392.0 MHz and 392.2 MHz. As shown in next picture, it would set three filters with frequencies 392.00625 MHz, 392.1 MHz and 392.19375 MHz for the four carriers in the packet, and two more filters for the two separated carriers. It is certainly possible to do this same operation manually, in the Filter Control Frame, although it would be less convenient. Should the user set filters without keeping these rules, the software would show a warning message, as in the following image:
 Password (only via web connection): to modify webpage password, old password is required, and new password needs to be written two times. After clicking on “Apply Changes” link, new authentication screen appear, where user must write new password.  SNMP (only via web connection): user can configure through webserver some SNMP parameters:
o Read-only community and read-write community: set passwords for SNMP agent (typically "public" / "private") o Watchdog Period: time in minutes without external IP access to the device (HTTP, SNMP or PING) after which the embedded Ethernet module will reboot just in case it were stuck. It does not affect RF functioning. Default value is 1440 minutes, i.e. one day. o Ethernet RESET: resets Ethernet module. o Delete All Traps: clear all alarm conditions and sets trap counter to zero o Trap community: set trap community for each connection to SNMP Manager o Trap port: set UDP port for SNMP trap sending. Default standard port is 162. SNMP polling is done through standard port nr. 161. o Trap repetition: set number of traps that SNMP agent will send every time that alarm conditions vary. Maximum number is five repetitions and the time lapse between them is 10 seconds. o Manager Enable: enables each connection to SNMP Manager independently. If enabled, traps will be sent to manager IP address set in IP section. o Keep-Alive period: Keep-Alive traps can be sent periodically with the purpose of letting the SNMP manager know that the agent is working. The time in minutes between these traps is the Keep-Alive period. Default period is 60 minutes. A setting o 0 disables sending these traps. These traps are not affected by the Trap Repetition mentioned before.  Configuration o Apply Changes: as it is said above, this link is used to load changes to the Signal Booster, in configuration, tag, IP, password and date and time menus. After any configuration change, web page will show and icon that allows user to know if configuration has been successfully applied:
o Reload Settings: clicking this link, Signal Booster configuration data is refreshed.  Version: shows hardware, firmware and software versions of Signal Booster and serial number. RF parameters description “Status” menu shows whole RF configuration and monitoring data that are distributed along the webpage. The status window is divided in two main blocks: general control and filtering control. First, general control contains signal booster main configuration parameters, while second block is a list with variable number of rows (according to number of enabled filters) which contains detailed configuration and monitoring parameters of each filter. Maximum number of filters is 32 for narrow filters version and 8 for adjustable bandwidth version General control frame for narrow-band version General control frame for adjustable bandwidth version
General control frame for dual version  General control frame. There are four sub-sections inside this frame: o Main uplink control: RF main parameters regarding to uplink band are contained in this section: gain, output power limit, squelch threshold, squelch enable, PA enable control, RF output power indicator, and RF input overload, PA status and stability alarms. Next table describes information of this frame: Uplink frame Parameter Description Main Gain Set maximum gain of Signal Booster at UL band. Range can vary between models. Power Limit Set maximum output power of Signal Booster at UL band. System automatically will apply a correction to share this limit between the active channels. For instance, +18dBm band limit means +12dBm maximum output power per channels for 4 active channels. Range can vary between models depending on rated power. Squelch Enable Enabling this control, Signal Booster does not transmit in each channel if RF input power do not exceed the threshold level configured according to next row Squelch Threshold If squelch is enabled, input levels below this threshold are not transmitted.
PA Enable This control enables / disables PA UL: Green button and label “ON” means that PA is enabled, red button and label “OFF” means that PA is disabled RF Output Power Shows instantaneous RF output power at UL band Overload UL This alarm indicates that Signal Booster is being overloaded at UL band, due to very high RF input level PA Status PA status alarm indication based on current consumption All Filters Same BW If enabled, any change of bandwidth filter of any enabled filter will be applied to all UL filters o Main downlink control: parameters regarding to downlink band. They are almost equal to uplink band. Downlink frame Parameter Description Main Gain Set maximum gain of Signal Booster at DL band. Range can vary between models. Power Limit Set maximum output power of Signal Booster at DL band. System automatically will apply a correction to share this limit between the active channels. For instance, +36dBm band limit means +30dBm maximum output power per channels for 4 active channels. Range can vary between models depending on rated power. Squelch Enable Enabling this control, Signal Booster does not transmit in each channel if RF input power do not exceed the threshold level configured according to next row. Squelch Threshold If squelch is enabled, input levels below this threshold are not transmitted. PA Enable This control enables / disables PA DL: Green button and label “ON” means that PA is enabled, red button and label “OFF” means that PA is disabled
RF output power Shows instantaneous RF output power at DL band Overload DL This alarm indicates that Signal Booster is being overloaded at DL band, due to very high RF input level Comm. Error Indicates that communication with monitoring PA Board is lost. In this case, following three alarms will not be available AGC Fail This alarms appear if output power is higher than maximum output power (typical +37dBm) plus 3dB. VSWR Alarm appears if high reflected power is detected in “To mobile” connector Tx Power Low Indicates that measured output power at PA output is lower than expected according to RF input levels and configured gains General control frame for narrow band and dual version o General control General control frame Parameter Description Linked UL/DL frequencies If 'Yes' then frequency setting in DL will also modify UL according to frequency band split preset in factory. If 'No' then filter frequencies can be set independently in UL and DL. Squelch mode control If this control is set to “Linked”, DL channels without input signal (according to DL Squelch threshold) automatically squelch related UL channels
RESET Reboots digital signal processor Simplex Mode (only available in some narrow filters versions) If enabled, signal booster works in simplex mode. This is, any DL signal detected in any DL enabled filter blocks all UL filters and any UL signal detected in any UL enabled filter blocks all DL filters Temperature Shows internal Signal Booster temperature Rx Power Low Alarm is active, if signal is not detected in any DL channel Hardware fail alarm Indicates critical malfunctioning in digital signal processor Show filters Firmware selection (only for dual version) User can change filtering mode in case of dual version signal booster Simplex mode checkbox control is only visible in devices with such capability. It allows signal flow only in one direction, either uplink or downlink, at any given time. The chosen direction is made automatically based on signal detection which, in turn, depends on squelch. Therefore, turning on simplex mode automatically turns on squelch, both in uplink and downlink sections, and disables these controls for the user. Besides, it also sets squelch mode to "Not Linked" and disables this control, too. This is necessary since otherwise the lack of RF input signal in downlink would mute the uplink RF input, thus blocking all communication. The look of the general control frame in simplex mode is as in next image: Filter control frame for narrow-band version
 Filtering control frame. Filter control frame for narrow-band version Filter control frame for adjustable bandwidth version  Filter control frame: shows configuration and monitoring information of all filters. The frame is divided in two: uplink and downlink. Data showed in each half is symmetric. Filter control frame Parameter Description On Allows to enable/disable each filter Frequency Configures center frequency of each filter Bandwidth filter control for narrow-band version only There are up to five available filters (depending on factory setup) to adjust the trade-off between rejection to undesired signals and delay Fine gain control Each channel gain can be fine adjusted RF input power Shows RF input level for each channel Signal detection With this indicator, system shows if signal is detected at input, according to squelch threshold. Moreover, with Squelch Mode = ‘Linked’, UL shows no signal if signal is not detected in the same DL channel even if UL signal exceed squelch threshold. Similarly, with simplex mode enabled, if one signal is detected at DL band, all UL filters will show “No signal” RF output power Shows estimation for RF output level for each channel, according to programmed gain and AGC control. Shows
‘OFF’ in the same cases that signal detection shows ‘No signal’ AGC Indicates gain reduction due to power limitation control. In case of adjustable filter version, filter control frame is slightly different. According to entry mode button, frequency and bandwidth parameter configuration can be: o Center frequency (in 25KHz steps) and bandwidth filters (50KHz steps) o Start and stop frequencies (in 25KHz steps)
Spectrum Analyzer The spectrum analyzer feature of the Signal Booster is a useful tool for commissioning and troubleshooting. This section explains how to use it. Frequency at cursor positionStop frequency settingStop frequency settingScan refresh indicationResolution bandwidth & Sweep time readout Zero Span switchInput & Output trace enableUplink / Downlink switchUplink / Downlink switch Spectrum analyzer settings Input and output signals are scanned successively and can be shown or hidden independently: Spectrum input/output selection Either uplink or downlink signal paths are chosen and average up to 32 can help to clean noise signals. Resolution bandwidth and sweep time are set automatically.
Spectrum UL / DL selection When start and stop frequencies are set equal, then zero-span mode is activated to show evolution of signals with time, which may be of special interest with pulsed signals. The same thing can be achieved by setting the zero-span checkbox, with the convenience that start frequency change would also change stop frequency accordingly. Spectrum zero-span mode Resolution bandwidth becomes enabled in zero-span mode and sweep time is automatically set according to its setting, which is user selectable between 25.000Hz, 12.500Hz, 6.250Hz and 3.125Hz. Average setting will also impact sweep time in a similar way.

SNMP Agent Fiplex Signal Booster includes a SNMPv1 agent that allows user to supervise the device by means of 'SET' and 'GET' type commands and, asynchronous traps to notify alarm conditions can be sent. The device is intended to be monitored by a polling NMS but it can send traps to a NMS or Trap Receiver if enabled. Fiplex can provide a NMS system upon request. The following sections will show the user configurable, relevant information that can be read via SNMP from the device. The tables will describe these values in order to explain how the information has to be read and interpreted. MIB Description The associated MIB document is FIPLEX-BDA-SYSTEMv13-MIB.mib. The Fiplex MIB is divided into blocks. Each block describes the characteristics and values of a specific element but not all elements are implemented in this agent. Each MIB block is divided in two segments, named 1T and 2T. Segment 1T contains the information that is fixed & read only. Segment 2T has the information that can vary over time, regardless of it being read/only or read/write. The following sections will show the user configurable, relevant information that can be read via SNMP from the device. Manager This is a table with 2 consecutive elements, one for each NMS. No checking is done of the validity of the information stored in the table, so extra care must be taken by the user.

NMS: SNMP Managers table Network This is a table has just one element with two items. The first one is the device's IP address and it is read-only to avoid unwanted miss-configuration. This can only be changed by means of the embedded web server or locally, through USB, by means of the Fiplex Control Software. The second item is a “kind” of button intended for resetting the embedded Ethernet hardware interface.

NMS: SNMP Device table Additional information is shown by clicking on the link named “Description”. This extra piece of information comes from the fixed table, Dev1Table. The most relevant items in this table are the following ones: SNMP Device Group table Field Name OID Description Type Dev1TGroup[0] 1.3.6.1.4.1.26355.2.50.5.1.1.3.0 das.info (conformance group) R/O Dev1TurlExtern[0] 1.3.6.1.4.1.26355.2.50.5.1.1.19.0 URL of embedded web server R/O Alarms Alarms tables provide information regarding the status of key parts in the system. The fixed table gralAlarm1Table provides self-explanatory identifiers, gralAlarm1TId, for each relevant subject. The second item in each element of this table is the gralAlarm1TGroup. When the device being monitored is a Remote unit, this item just takes the value 'das.alarms '. However, since the Master unit carries information from all the devices in the whole DAS system, it provides a different value for each device to which the alarm is assigned to, be it the Master unit, any of the Remote units or any of the Expansion units. Therefore, the actual number of elements in this table for the Master unit, depends on how many devices compose the DAS system. The third item of each element, gralAlarm1TDescription, is left blank, since the first one suffices for that purpose. SNMP Alarm Group table Field Name OID Description Type

Aside from a faulty part, as the donor antenna or RF cable, this also might be caused be a problem with the base station or frequency configuration. Notice also that signal detection is dependent on squelch threshold setting. Because of that, this is considered a warning instead of an alarm.  AlarmTempHigh High device temperature (over 85ºC).  AlarmOverloadUplink Excessive RF input signal in UL.  AlarmOverloadDownlink Excessive RF input signal in DL.  AlarmTxLowDownlink Detected RF output power much lower than expected. Since output power measurement is performed by the dedicated monitoring board, a fault in that board would make this item be set as Unavailable and AlarmPAFaultDownlink set to true.  AlarmTxHighDownlink Excessive RF output power detected (3dB higher than rated). This is most likely due to bad gain settings, since AGC would limit output power otherwise.  AlarmPAFaultUplink Uplink Power Amplifier failure. This alarm is available for certain amplifier types only, and for the rest an 'unavailable' status is set in the next table.  AlarmPAFaultDownlink Downlink Power Amplifier failure. A communication failure with the dedicated monitoring board itself, throws this alarm, too.  AlarmVswr RF mismatch of PA output is detected. Since VSWR measurement is performed by the dedicated monitoring board, a fault in that board would make this item be set as Unavailable and AlarmPAFaultDownlink set to true.
SNMP Alarms Group table On the other hand, the mutable table gralAlarm2Table provides the actual status of each alarm. This table has one element for each element in gralAlarm1Table. Each element has two items. The first one is a status identifier, gralAlarm2TStatus, be it 'ok', 'warning', 'fail' or 'unavailable'. The second item is a short description of the fault, mainly for human readability. SNMP Alarm table 2 Field Name OID Description Type GralAlarm2TStatus[0] 1.3.6.1.4.1.26355.2.50.13.2.1.2.0 Status enumeration R/O GralAlarm2TEventDescription[0] 1.3.6.1.4.1.26355.2.50.13.2.1.3.0 Short descriptive string R/O The next picture is the MIB tree view of this table, and the Fiplex NMS provides a combined view of both tables and groups alarms:
SNMP Alarms table NMS: SNMP Alarms table
SNMP Traps General Explanation For any event that may set or clear an alarm in the gralAlarm2Table, there is a SNMP trap that may be sent by the embedded SNMP agent to the manager, if enabled. Therefore, the list of traps closely reassembles the entries in the alarms table. Furthermore, there is also a keep-alive trap for letting the SNMP manager that the agent is working, in case that polling is not being done. Each trap message has the following fields (except for the keepAlive trap, whose only object is the agent's IP address  An identification number associated to the event being signaled.  A severity indication number.  A short string description for human readability. The following list gathers all the available identifiers: SNMP Trap descriptions and Enterprise Specific IDs Source event Description ID Keep-alive System sends this trap periodically. Period is set with Keep-Alive Period setting of the trap manager. When this trap is thrown, the trap counter is not incremented. It is always in cleared state. 3 General Failure This trap indicates that the board controller is not responding to the remote supervision system. 5 Hardware Failure This trap indicates malfunction related the Digital Signal Processor. 6 Rx Input Low DL Downlink input signal is not detected in any active filters. 10 Temperature Internal repeater temperature exceeds +85ºC. 11 Rx Overload UL Uplink RF input level overload 20 Rx Overload DL Downlink RF input level overload 21 Tx Low DL Detected Downlink RF output power is lower than expected. 30 Tx High DL Downlink RF output power too high 31 PA Fault UL Alarm for the UL Power Amplifier if available. 40 PA Fault DL Alarm for the DL Power Amplifier. It may be caused by communication error with PA monitoring module. 41 VSWR Excessive DL output reflected power: antenna mismatch. 50
As it turns out from this list, there is a one-to-one relationship between events triggering traps and their notification identifiers. But the trap identifier does not tell whether the event was to trigger the alarm state or to cancel it. That is the purpose of the severity identification number in the trap message. The following table lists the severity numbers used: SNMP Trap status binding Severity Description StatusID Trap status binding Binding string CRITICAL System malfunction comes into effect 1 3 fail WARNING System warning comes into effect. 4 2 warning CLEARED System malfunction or warning is canceled. 5 1 ok UNAVAILABLE System state cannot be determined 6 99 unavailable The character string attached to each trap message includes both a short event description plus a severity description such as “OK” or “FAIL”. As an example, the following picture shows a snapshot of a trap receiver getting traps from a unit at address 172.18.21.10. The time-stamp shows time since system boot and SNMP Version is '1'. The severity is set to 'warning'. SNMP Trap in trap receiver Example trap capture
