5 NOC-NEM INTERFACE
NOC-NEM INTERFACE The EMS Network Operations Center–Network Element Manager (NOC-NEM) Interface allows you to communicate with EMS remotely using the commands specified in this section. You can also enter the same commands using the NOCNEM window in the Maintenance Interface. 5.1 Summary of Tasks and Commands Table 34 lists the main tasks that can be done in NOC–NEM and tells where to get instructions for each task (NE = network element).
Setup Instructions 5.2 Section 9 Setup Instructions 5.2.1 Requirements To access the NOC-NEM interface: • You must have either a dumb terminal or a computer with a terminal emulator program. • The terminal emulator program must be directed to a serial port with a direct data link to the EMS NOC Comm port on a computer on which EMS is running. • The terminal port must be configured to a baud rate of 9600, with one stop bit, no parity. 5.2.
NOC-NEM Interface 5.3 Data Format Data Format The NOC-NEM language consists of two types of character strings: “commands” and “response messages.” Commands are entered by the user to request NOC– NEM to perform particular actions. Response messages are returned by NOC– NEM to indicate its response to commands. Usually, commands and response messages occur on a one-to-one basis, with a response message returned for each command.
POST STATUS Message 5.4 Section 9 POST STATUS Message At a regular time interval, the NOC-NEM interface queries each network element and displays the current status information for that network element. The resulting unsolicited display is called a POST STATUS message. The interval at which POST STATUS messages are displayed can be specified by the user for a particular network element or for all network elements.
NOC-NEM Interface Commands • Host is listed first, then remote. • Values given, in order, are: host node number and host site name, remote node number and remote site name, and site number (one per host remote pair). Below is an example of a single line returned: (37)Askov & (36)Tower & 12 \ In this example: • (37) is the host node number, Askov is the host site name • (36) is the remote node number, Tower is the remote site name • 12 is the site number for this host/remote pair NOTE: You canno
Commands Section 9 3. Interpret the response as follows: • Each line (after header) represents one host/remote pair. • Host is listed first, then remote. In the above example, the host is identified as (35 Host.11) EmbarrassMinn. The numeric values in parentheses are the node number and site number. Host and remote share the same site number. • Values given will be one of the following: • Red = one or more major alarms exist.
NOC-NEM Interface Commands 3. Interpret the response as follows: The line after the header is the site name (Askov in the example above). If multiple network elements are queried, there will be an END line after each network element, as shown above, with a double END line after the last network element. Examples DEMS 43 GET SITENAME DEMS ALL GET SITENAME 5.5.
Commands Section 9 Apr 3, 2003 1:36:35 PM: DEMS(35 Host.11)EmbarrassMinn SET SiteName Warroad \ END Apr 3, 2003 1:36:35 PM DEMS (Host.11)Warroad POST Status \ Site Name from EmbarrassMinn to Warroad \ END 5.5.5 GET SWINFO This command can be used to determine which software programs and versions are currently loaded on a network element. You can identify the network element using either site name or node number. You can also query for all network elements.
NOC-NEM Interface Commands Examples DEMS 43 GET SWINFO DEMS OwatWalMart GET SWINFO DEMS ALL GET SWINFO 5.5.6 GET ALARM This command can be used to determine the current state of a specific alarm at a network element identified by its site name or node number. You can also query for all current alarms and/or for all network elements currently known to EMS. To query for alarms 1.
Commands Section 9 3p8Volt Ok \ END • A status of FAIL (such as shown below) indicates the alarm indicator is functioning correctly and the alarm is active. 1130 23-Mar-01 DEMS 48 GET ALARM 3P8volt \ 3P8volt FAIL \ END • A REJECTED message such as shown below indicates the alarm indicator is not functioning correctly. 1130 23-Mar-01 DEMS 48 GET ALARM 3P8volt \ REJECTED \ END Examples DEMS Askov GET ALARM 3P8volt DEMS 35 GET ALARM 3P8volt DEMS Askov GET ALARM ALL DEMS ALL GET ALARM ALL Table 35: Ho

You can identify the network element using site name or node number. To query for current parameter values 1.
Commands Section 9 Examples DEMS MainTower GET DATA 3P3Volt DEMS MainTower GET DATA ALL DEMS ALL GET DATA ALL 5.5.8 GET STATUS This command can be used to determine the status of a network element identified with a site name or node number. The information returned includes all parameter values and all alarm values. To obtain a status display 1.
NOC-NEM Interface Commands information, and writes the status information to the system log file. The status information includes all parameter values and all alarm states. The time interval for any network element can be changed using a SET RECORD command. EMS also writes a status report into the log file whenever any alarm changes in state (for example, from Green to Red). An entry remains in this file until the age of the entry in days is the “trim time” value plus one.
Commands Section 9 DEMS ALL GET RECORD 5.5.10 SET RECORD This command can be used to set the time interval (minutes and seconds) at which NOC-NEM will query for network element status and write the information to a log file. (For a more thorough explanation, see the description for the GET RECORD command, above.) The log file is the source of the information returned in response to GET PLAYBACK commands. NOTE: You can set the SET RECORD time interval to zero, causing no records to be kept.
NOC-NEM Interface Commands 5.5.11 GET POST This command can be used to determine the current time interval (in minutes and seconds) that NOC–NEM is using for POST MESSAGE displays. The query can be made for a specific network element or for all network elements. Once per the time interval specified, NOC–NEM queries the network element to obtain its current status information and then displays the information unsolicited on the NOC-NEM screen.
Commands Section 9 You can also use this command to turn off the POST MESSAGE display, for a specific network element or for all network elements, by setting the time interval to zero. To set the POST MESSAGE period for a network element 1.
NOC-NEM Interface Commands 5.5.13 GET PLAYBACK This command can be used to display status information extracted from the EMS log file. The command output can be requested for a particular network element or for all network elements reported in the file. Each set of values is the result of one query to the network element, and includes all parameter values and all alarm states obtained from that query.
Commands Section 9 DEMS Site_Name SET PLAYBACK Start_Time_Date End_Time_Date (or) DEMS Node_Number SET PLAYBACK Start_Time_Date End_Time_Date where Site_Name is the site name of the network element, Node_Number is the Host Node or Remote Node value (as displayed in the Maintenance interface View Catalog window), and Start_Time_Date End_Time_Date are in the format HHSS DD-MON-YR (see examples below). Use Site_Name = ALL to apply the same time interval to all network elements.
NOC-NEM Interface Commands want to query. Use Site_Name = ALL to query for all network elements. Use Alarm_Name = ALL to query for all alarms. 2. Look for a response like this 1130 23-Mar-01 DEMS MainTower GET ALARMFILTER PriRXLite \ PriRXLite ON \ END where ON indicates that the alarm is being reported and OFF indicates that it is not being reported in POST STATUS messages. Examples DEMS WasecaPower GET ALARMFILTER PriRXLite DEMS 13 GET ALARMFILTER ALL DEMS ALL GET ALARMFILTER ALL 5.5.
Commands Section 9 Examples DEMS OwatWalMart SET ALARMFILTER 3P3Volt Off DEMS 11 SET ALARMFILTER 3P3Volt Off DEMS All SET ALARMFILTER ALL Off 5.5.17 GET THRESHOLD This command can be used to determine the current value for remote forward attenuation. To determine thresholds 1.
NOC-NEM Interface Commands 5.5.18 SET THRESHOLD This command can be used to set the remote unit forward path attenuation. This setting affects the strength of the forward path RF analog signal transmitted from the remote unit antenna. To set an alarm threshold 1.
Commands 116 Element Management System (EMS) 4.
LOSSARY Alarm: A physical or functional state affecting the ability of a host/remote pair to function normally. Reported by the host/remote pair to EMS to notify the user that such a state exists. A-bis interface: Interface used in Digivance SDR systems to connect a BTS server to an upstream device. In EMS, it is a packet-switching interface using Voice Over Internet Protocol. Attenuation: By definition, a function that lessens the strength of a signal.
References: direct data link connection to this port allows a remote user to use the NOC– NEM Interface. See also, NOC-NEM Interface. Fault: Physical or functional failure in a host/remote pair serious enough to cause an alarm. Forward Path: Signal path in the direction from the BTS to the cell phone. FPGA: Field Programmable Gate Array. Bit map defining a gate array. Provides operating logic for network elements.
Glossary NOC–NEM Interface: Acronym for Network Operations Center–Network Element Manager Interface. The EMS character interface, available as a window within the Maintenance Interface, or remotely using a terminal or a computer with a terminal emulator program. Normal Mode: One of the four operating modes of host/remote pair unit. In this mode the host/remote pair are transporting RF signals normally. Operating Mode: Any of the four basic operating modes of a host/remote pair.
References: Spectrum Transport Module (STM): One of the two modules in the remote unit. Its job is to transport the RF spectrum between the antenna and host unit using optical signals over fiber or an optics free space link. Standby Mode: One of the four operating modes of the host unit. In this mode, RF transport is disabled and power consumption is minimized. Standby mode occurs only due to a user request and can be turned off by the user to return the host unit to a Normal operating mode.
