Into the tool bar, there are, as push-buttons, the following menus:
• Connect, contains the commands to activate the connection with every equipment present into the network.
If the operation has been successfully executed, the Connect label is replaced with the Disconnect one. The choice of this last option allows deactivating the connection.
• Login, contains the commands to activate the login with one or more remote equipment present into the Equipment list area.
• Logout, contains the commands to deactivate the login with one or more remote equipment present into the Equipment list area.
• Refresh, contains the commands to request the updating of the information present into the Equipment list area.
• Equipment, contains the commands to check the configuration, composition, functional status etc. of the equipment selected into the Equipment list area.
• Network, contains the commands for the management of the users that can use the program.
• Options, contains the commands to customize the program (number of signals that can be stored into the alarm history, connection modes and parameters, etc.).
• Tools, contains the command to save, open, display, transfer a configuration file, the command for the management of the “remote equipment” list and the command to display the monitoring files (alarms and PM measurements) detected with the Siae Alarm &
Performance Monitoring program 34.
Warning. Some push-buttons are characterized by the arrow symbol (q), the selection of such a symbol opens a pop-up menu that lists the options coupled to such a menu.
34 The Alarm & Performance Monitoring program allows monitoring all the connected equipment and memorizing into a file the results of the PM measurements and the alarms/events.
More detailed information concerning the program are reported into the Alarm & Performance Monitoring on-line guide/manual.

4.4 “Station list” area
When the connection with the local equipment has been activated, into the Station list area, the program points out the list of the stations which group the equipment (local and remote ones) present into the “remote equipment” list (Remote Element List) 35 as shown into Figure 2.
The equipment are displayed into the Equipment list area. The contents of this area change, according to the selected station. In fact, when the user selects a station, into the Equipment list area, the program shows only the equipment coupled with such specific station. The functional status of the other connected equipment is pointed out by the resuming boxes of the stations that
“contain” the equipment (refer to the notes of Figure 2).
Warning. The station does not have any particular meaning; it has been introduced simply to help the user during the localization of the equipment.

Notes of Figure 2
(1) The user defines the name of the station during the setting of the “remote equipment”
list, he can change it later.
The wording Undefined points out that it has not been assigned any name to the station
36.
35 The “remote equipment” list is a list that contains all the information concerning the network equipment to which the program has to be connected.
Warning. The “remote equipment” list has to be set by the user and it can be increased or changed at every time. The user can save the list into the equipment controller or into a file.
36 Into the Undefined station, it is possible to have present the equipment with the activated connection (local equipment).
This situation is present if, into the “remote equipment list” of the local equipment, it has not been inserted the local equipment itself.
In such a case, the program does not know to which station it has been coupled the local equipment and, therefore, it will couple it with the Undefined station.

(2) With details, from L.H. side to R.H. one, the box:
• <alarms>, points out the status of the alarms.
The box, according to the severity of the alarms present into the equipment, can get different colours and wordings. With details, the box:
− Green – without wording, points out that the equipment contained into the station does not show alarms.
− Light blue - wrn, points out that the most serious alarm present into the equipment, contained into the station, has Warning severity.
− Yellow – min, points out that the most serious alarm present into the equipment, contained into the station, has Minor severity.
− Orange – maj, points out that the most serious alarm present into the equipment, contained into the station, has Major severity.
− Red – crt, points out that the most serious alarm present into the equipment, contained into the station, has Critical severity.
• mop, points out the activation of manual forcing operations (for instance a loop). With details, the box:
− Green – mop, points out that the equipment contained into the station does not have any active manual forcing.
− Light blue - mop, points out that at least one equipment contained into the station has an active manual forcing.
• dwl, points out if the updating of the software/firmware (sw/fw) is on progress. With details, the box:
− Green – dwl, points out that no one equipment contained into the station is executing the updating of the sw/fw.
− Light blue - dwl, points out that at least one equipment contained into the station is executing the updating of the sw/fw.
• tmo, points out the connection status. With details, the box:
− Green – tmo, points out that no one equipment contained into the station is in disconnected status.
− Red - tmo, points out that at least one equipment contained into the station is in disconnected status.
(3) The description of the boxes is the same one pointed out at point (2).
In this case, the status of the boxes points out the resuming status of all the equipment present into all the stations.
(4) The flashing of the Acknowledge push-button and of the symbol (*) on the side of the name of a station, points out that at least one of the boxes of the station under examination has changed status (it has switched from activated to deactivated or vice versa).
For instance, Let us suppose that into the Station A station (refer to Figure 2) the dwl box is activated (box with light blue color); the program points out the deactivation of the box (status change – it switches its color from light blue to green), through the flashing of the Acknowledge push button and of the symbol (*) on the side of the Station A wording.
The user can deactivate (and then activate again) this function, define the frequency of the flashing and the “status changes” that cause the flashing (refer to Acknowledge card).
Warning. Press the Acknowledge push-button, to stop the flashing of the push-button itself and to remove the symbol (*).
Warning. If the user activates the connection with an equipment and the remote equipment list of such an equipment had been set through the release 1.0 of the SCT/LMT program, the Undefined station contains all the equipment present into the list.
The user can reorganize the remote equipment list by means of the Subnetwork Configuration Wizard command.

4.5 “Equipment list” area
Into the Equipment list area, only when it has been activated the connection with the local, it is pointed out the functioning status of the local equipment and of the remote ones present into the
“equipment remote” list.
As “local equipment”, it is intended every equipment present into the network to which the user has asked for the connection.
When the local equipment has been connected, it communicates to the program its functioning status then, it makes available for the user the functioning status of all the equipment of the network to which the user itself is directly or indirectly connected (remote equipment) and present into the Remote Equipment List 37.
When an equipment has been connected, the user can check the functioning status, the detail of the current alarms , the version of the equipment software/firmware, the composition, the features, the results of the performance measurements (if such ones have been activated), the connection parameters, open the LCT interface and check the configuration parameters (status of the connected/monitor equipment).
To operate directly on the equipment management 38 opening the LCT interface and checking the configuration parameters, it is necessary to ask for the “login” that is the equipment access (connected/login equipment status 39).
For the local equipment, the login request is automatically forwarded when it is requested the connection. For the remote equipment, the login request has to be forwarded by the user.
Then, it is possible to deactivate the access to the equipment (logout). This command can be forwarded to every remote equipment in connected/login status but not to the local equipment.
Warning. Into the Equipment list area, the program displays ONLY the equipment present into the station selected into the Station list area, as shown in Figure 3.
In fact the contents of the area under examination change according to the selected station.
For instance, in Figure 3, the program points out only the equipment coupled with the Station B.
The functional status of the other equipment present into the “remote equipment” list connected with the program, is pointed out by the resuming boxes of the station to which the equipment are coupled.
To display the record relevant to a specific equipment, select the relevant station before.
Warning. The user can couple one equipment to one station only.
37 The “remote equipment list” is a list that contains all the information concerning the network equipment to which the program has to be connected.
Warning. The user has to set the “remote equipment” list and it can be increased or changed at every moment.
The user can save the list into the equipment controller or into a file.
38 Warning. The commands and the operations that can be executed by every SCT/LMT user are defined by his user profile.
39 Warning. In this status, it is possible to execute also all the operations available when the equipment is in connected/monitor status.

Notes of Figure 3
(1) When an equipment is in connected status (login or monitor), the relevant record shows the following information:
• “Latch” symbol. Possibility to execute every changes into the equipment configuration. The symbol:
− , points out that the SCT/LMT user can change the configuration parameters.
− , points out that the SCT/LMT user (independently from his profile) can not change any configuration parameter of the equipment.
In this case, the system does not provide, for the SCT/LMT user, the possibility to execute the equipment login 40.
The enabling for the changing of the parameters is set by network element manager (Siae NMS5UX supervision system).
• Alarm Summary/ManOP/... field. Functional status of the equipment. When the box:
− Critical is red, it points out that it is activated at least one alarm with Critical level.
− Major is orange, it points out that it is activated at least one alarm with Major level.
− Minor is yellow, it points out that it is activated at least one alarm with Minor level.
− Warning is blue, it points out that it is activated at least one alarm with Warning level.
− ManOp is blue, it points out that it is activated a manual forcing (for instance a loop).
− Dwload is blue, it points out that the firmware updating is on progress.
The absence of alarms, of manual forcing or of download ones on progress is represented by the green box.
• .../Station field. It is the network identification of the equipment.

The wording MIB vers…, positioned after the equipment type, points out the MIB version (Management Information Base).
Warning. If the system does not point out the MIB version, it means that the relevant value is not available into the MIB loaded on the equipment under examination.
• Login field. It is the login/monitor status of the equipment. Then, in login status, it is pointed out the profile of the user who has executed the request.
With details, the wording:
− Read only, Read and write, Station operator or System, points out that the equipment is in connected/login status and that the user, who has requested the login, has respectively a profile of Read only, Read and write, Station operator or System type.
− Monitor, points out that the equipment is in connected/monitor status.
(2) The record, relevant to the local equipment, is identified by the wording (Local) present into the Login field; usually the local equipment is represented by the first record of the list.
(3) The records, of the remote equipment, are identified by the absence of the wording (Local) into the Login field. While, the wording (Remote Link) points out the element, set into the “remote equipment list”, placed on the other side of the local equipment-remote equipment hop.
(4) After having activated the connection, it is possible that the connection is temporarily interrupted, that the user asks for the data updating, etc.
These situations are pointed out into the Equipment list area through the displaying of the following wordings into the Alarm Summary/ManOP/Station field:
• Connecting. Transitory status; it means that it is on progress the first connection.
• No response. Transitory status; it means that the equipment has not answered to the first connection attempt.
• Retry connection. Transitory status; It means that a re-connection attempt is on progress 42.
• Timed Out. Transitory status; it means that the equipment has not forwarded the answer to the connection attempt into the set time-out time 42.
• Refreshing. Transitory status; it means that the information updating is on progress.
The updating request is forwarded by the user by means of the Refresh menu.
• Disabled by user. Permanent status; it means that the remote equipment has been disabled by the user (by means of the Disable command).
In this condition, the program stops the dialogue with the equipment or the re-connection attempts.
• Authentication fail. Permanent status; it means that during the connection or the re-connection attempt of a remote equipment, the network password inserted by user,
42 The times and the connection and re-connection modes can be set by the user.
30 SCT/LMT Release 1.4 – MN.00095.E – 013
during the connection procedure has not been considered as a valid one or it generally points out an error during the connection.
• No Route to Host. Permanent status; it means that the program is not able to forward the data to the equipment because it does not have all the requested information to reach such an equipment.
This situation occurs, for instance, when the equipment that has to be connected does not belong to the same network of the machine where it is installed the SCT/LMT program and the user has not defined a machine that acts as a gateway between the two networks.
• Login Time Out. Permanent status; it points out that it is expired the possible timeout coupled with the user or that the SCT/LMT user with System profile or the NMS5UX user has forced the logout of the user under examination.
The user logout corresponds to the disconnection of the relevant equipment.
• Too many users. Permanent status; it points out the equipment is already connected with the maximum number of users 43.
Press the Refresh menu to check if one connection is “available”. If one connection is available, the equipment switches in connected/monitor status, on the contrary, it remains in Too Many User status.
Warning. The disconnection (also the temporary one) of the local equipment causes the automatic disconnection of all the remote equipment 44.
4.6 “Alarm history log” area
Into the Alarm history log area, it is displayed the history 45 of the alarm 46 and status 47 signals relevant to all the equipment present into the network and actually connected or that have been connected to the SCT/LMT program.
The Alarm history log area is always present into the SCT/LMT window, and it is represented in Figure 4.
43 Warning. At each single equipment, it is possible to connect at the same time 6 users. The sixth user can require for the login only, if he has the System profile.
For instance, if 5 users are connected, in connected/login status, to an equipment and an additional user, with Read only profile (or Read and Write or Station Operator one), requires for the connection, the equipment does not allows the execution of such an operation. On the contrary, if the connection has been requested by a user with System profile (SYSTEM or NMS5UX user), the equipment accepts the request.
It is possible to check the number and the profile of the users connected to the equipment, opening the Logged User Viewer window.
44 This could be valid if the remote equipment are physically connected with the SCT/LMT program, through the local network (LAN).
45 As “history”, it is intended the list of the signals acquired and stored by the program during the time.
46 The word “alarm” means the signal of a failure created by an error or by a malfunctioning of the equipment or of one of its elements.
Warning. Into the alarm history, it is stored as the detection signal as the alarm reset one.
47 The word “status”, on the contrary, identifies the signals that refer to every event that does not point out a malfunctioning but a status change, an operation on progress or a functioning indication.
The status signals can be communicated from the equipment to the program (into the description, such ones will be called status signals) or it can be the program itself to create such signals (into the description, such ones will be called event signals), for instance, each time that the system executes the connection or the disconnection of an equipment, the SCT/LMT stores and displays a signal into
The status signals can be communicated from the equipment to the program (into the description, such ones will be called status signals) or it can be the program itself to create such signals (into the description, such ones will be called event signals), for instance, each time that the system executes the connection or the disconnection of an equipment, the SCT/LMT stores and displays a signal into
