ECOTEL® VTMpro 2005-06-08 Page 39 Loudness To GSM Configures the loudness to the mobile network. The range is 0 (quiet) to 3 (loud). ATTENTION A change becomes not valid before a reboot has been done to the specific channel. Loudness to PCM Configures the loudness to the fixed network. The range is 0 (quiet) to 3 (loud). ATTENTION A change becomes not valid before a reboot has been done to the specific channel. Fieldstrength limit If the received power level under-runs a specific level then the voice quality suffers from it. So the user can define that specific value. If the level under-runs this level then the concerning channel will be blocked terminating calls until the value exceeds this level. 10.3.2.2 Channel This filed contains means affecting one specific channel Reboot Pressing this button reboots the specific channel. The channel will be registered out and the GSM module is switched off and on. Active calls over this channel will be abandoned. After reboot the channel will register automatically and is available again. This feature can be useful to resume incorrect channels. Reregister Pressing this button registers the channel out of the network an in again. The GSM module is not switched off. After reregistering the channel is available again. Active calls will be abandoned. This feature is useful to get a better registration on a other visible base station with better receive power level or less traffic. Freeze This button causes the specific channel to register out and not in anymore. The GSM module is not switched off. To resume register state the “Reboot” button has to be pressed. This feature is useful if the base station is overloaded. Then it is possible to reduce the load by the ECOTEL® VTMpro from the basestation. Switch Off This button has the same effect like the freeze button plus switching off the GSM module. Channel Paramters Provides a set of GSM channel and module parameters Field strength Shows the receive power level in a bar and in letters. The value is dBm.
ECOTEL® VTMpro 2005-06-08 Page 40 IMEI Shows the IMEI of the mounted GSM module. This number characterizes one individual module. Manufacturer Shows the manufacturer of the mounted GSM module. Model Shows the model of the mounted GSM module Revision Shows the firmware revision of the mounted GSM module BCCH Shows the Broadcast Control Channel. The logical channel the basestation sends parameters necessary for communication. LAC Location Area Code or Local Area ID (LAI). Represents the geographical area the mobile is registered. BCC Base Station Color Code CID Displays the GSM Cell ID the module is registered to. 10.3.2.3 Layer2Trace This field provides the possibility to select certain processes at debugging the GSM port. The meaning of the most used are following: GREG: (GSM Registration) Registration information. Interesting at registering problems, to find out blocked or disturbed sim cards. Also interesting to monitor gathering cell paramters. Causes continuing trace information even when there is no call on the channel. GCON: (GSM Control) Provides information about the calling procedure. Causes only trace information when there is a call establishing or finishing, not during the call. Interesting to find out problems at establishing calls. GIF: (GSM Interface) Displays the message flow between the controller on the GSM card and the mounted GSM module. Causes continuing trace information even when there is no call on the channel. GSMS: (GSM SMS interface) Displays processes concerning SMS receiving and transmitting. PTS: (PCM Time Slot) Displays the coupled time slot from the specific board to the internal PCM bus. To get trace information refer also to chapter “Layer2&3 Trace”, because there must additional switched on the specific channel on debugging level 2.
ECOTEL® VTMpro 2005-06-08 Page 41 ATTENTION Traces must be handled very carefully not to overload the system. To much trace information influent the system severe. In normal operation traces should be switched off! 10.3.2.4 Sim Properties Generally the ECOTEL® VTMpro knows two ways to handle SIM cards for the GSM channels. For basic functions it is possible to handle the SIMs manually. In this way it is possible to enter a PIN or switch between several provided SIMs on a Multi-SIM-Carrier. To use more sophisticated functions the SMC (Sim Management Center) must be used. This functions are described later in this document. 10.3.2.4.1 Register SIM / Release SIM This buttons provides the function to enable or disable a SIM on this specific channel. The SIM is not really registered out of the network after pressing “Release SIM”, so it will be available right in the moment “Register SIM” has been pressed. If a SIM is released no calls will be routed over the relevant channel. 10.3.2.4.2 Manual SIM Switching This check box enables the manual SIM switching already described. Default Destination For special routing features it is sometimes necessary to assign a GSM channel a individual number. This number can be a individual SIM party number or any other. At further routings e.g. into fixed network this number will be sent as originator. SMSC In this filed the individual SMSC (Short Message Service Center) must be entered. This entry belongs to the mobile network provider and is necessary for using SMS send and receive services. ATTENTION There can be entered only one SMSC for each GSM channel. If there is a switching between SIMs from different mobile network providers, then SMS services may not work using every SIM! PIN If PIN entering is not deactivated on the SIM card normally there is a PIN for registering into mobile network needed. This PIN must be entered or changed before the SIM is put into the gateway. Otherwise it can happen, that the wrong PIN is entered. In this case the ECOTEL® VTMpro lets for safety reason always one trial free. The SIM must be taken out of the gateway and PIN must be inserted to a mobile phone to use last chance to enter the PIN and set free three more trials of entering. ATTENTION
ECOTEL® VTMpro 2005-06-08 Page 42 There can be entered only one PIN for each GSM channel. If there is a switching between SIMs from different mobile network providers, then this PIN will be used for all SIMs. For this reason it is strongly recommended to use the same PIN for all available SIM cards. LAIN The ECOTEL® VTMpro GSM channels provide the chance to register to a network automatically or to force registering to a specific network. This choice is only available if the SIM card supports roaming on any level. In this case the LAIN (Location Area Identity Network) code must be entered into the specific field. If no code is entered automatic net search is activated. SIM If there are more SIM cards available on the used SIM carrier, the SIM can be chosen by this element. 10.3.2.5 Sim Parameters Attribut: Description: IMSI Displays the IMSI (International Mobile Subscriber Idendity) for each SIM. With this number each SIM can be identified unambiguously. The IMSI has following elements: xxx yyy zzzzzzzzzz xxx: Mobile Country Code yy: Mobile network code zzzzzzzzzz: Subscriber identification State Shows the register state of the SIM card. Following register states are possible: • SIM released • Not logged in • SIM OK • Searching for Network • Registered • Registered Roaming SIM Displays the actual selected SIM. PLMN Displays the network the channel is registered to actually. ATTENTION Normally this PLMN should correspond to the first 5 digits of the IMSI to confirm registering into home network. Otherwise there is the danger of paying to expensive fees at using the GSM channel! Codec Displays the used codec on the channel. The following codecs are possible: • Half rate (low speech quality) • Full rate (good speech quality) • Enhanced full rate (best speech quality) The rate is dictated by the base station. Sometimes network providers reduce to half rate in order to save bandwidth. TCH Displays the TCH (Traffic Channel). Via this channel the user data is transferred between GSM module and base station
ECOTEL® VTMpro 2005-06-08 Page 43 TADV Displays the TADV (Time Advance). This parameters indicates the distance between GSM module and base station. One digit represents about 550 meters. The value range is 0 to 63. PWR Displays the actual output sending power of the module in dBm BER Displays the BER (Bit Error Rate). Normally the value should be cero. Otherwise the are problems in the channel or low receive power level. 10.4 ISDN After connecting a port of the ECOTEL® VTMpro to any other equipment the corresponding button in the vertical icon bar must turn green. Otherwise the port can not be used. If the port will not become active the settings and the cable pinning must be checked!

ECOTEL® VTMpro 2005-06-08 Page 53 11. Routing To get routing setup select “Routing” with the mouse on the vertical icon bar. Vertical Icon Bar: Configuration Panel: In conjunction with the routing panel there are also buttons in the horizontal icon bar important: Routing 11.1 Establishing a new routing step by step For a quick introduction there is assumed a simple example where calls come from fixed network via E1 and have to be terminated to GSM. There are no further options like number crunching or differentiating between more carriers needed. 1. First press the button “New Routing” in the “Routings” field. 2. Select a connection type. Normally “Audio Connection” is selected for voice functions. 3. Give the routing a name in the “Connection Property” field. 4. The settings are confirmed in the “Routings” list box. 5. Create a new port by pressing the “New Port” button in the “Port Routing List”. The new port brings new options in the right side of the window. 6. In the “Port Property” filed you can give the new port a individual name. If you do not name the port a default name will be given. 7. Give the port also a type. For typical routing tasks type “Channel Group” is suitable. The options in the right under part of the window belongs individual to the type and changes with the type. 8. If “Channel Group” has been selected, a specific kind of channels must be selected too from the tree view. The channels can be selected on a different depth, from whole controller to a single channel. There can also selected more than one
ECOTEL® VTMpro 2005-06-08 Page 54 item. Confirm selection by pressing the button “Add Board-Controller-Channel”. In this example the select the “npci8280.0”. 9. Create another port by repeating the steps 5 to 8. In this example choose the channel group “isa4tc.1” in the tree view. 10. Every port must also have a destination or even a alternative destination. Select a destination in the “Destination” list. The lists “Destination” and “Rerouting” grow with the created ports. 11. Finish the simple routing by adding another port. This port must have the type “Audio2Audio” for a audio connection. In the area bottom right there can be selected when the voice path shell be coupled. 12. Every new routing or every change must be confirmed by the “Activate Routing on Gateway” in the horizontal icon bar. 13. There can be provided more routings within one routing list. For a alternative routing list repeat the steps 1 to 12. The search sequence can be selected be the green arrows. 14. Now there can be terminated calls from fixed network in to mobile network. 11.2 Routing features in detail 11.2.1 Philosophy The routing concept is based of ports and virtual ports. Ports are linked with physical ports like E1 or GSM. Virtual ports are steps in routing between two physical ports and can influent the behavior of the routing. Every port has a source and a destination. It is also possible to jump within the port list in dependence of a result or setting. 11.2.2 Routings The routing filed contents features to create new or manipulate existing routings. Every routing consists of ports and virtual ports. In the routing list box there are displayed the existing routings and its options: Idx: Every routing entry has its own index number Name: Every routing line has its individual name Type: Every routing has its individual type. See also chapter “Routing type”. 11.2.2.1 Routing Type The routing is basically characterized by its type. The following types and its functions are available. The type refer to the kind of incoming connection: Attribute: Description: Audio Connection If incoming traffic is audio signal then this type must be selected Data Connection For incoming traffic data, this type must be selected SMS Connection For incoming SMS messages to be routed or converted this type must be selected Email Connection For incoming Email messages to be routed or converted this type must be selected
ECOTEL® VTMpro 2005-06-08 Page 55 11.2.2.2 New Routing -Delete Routing – Copy –Paste – Sequence Attribute: Description: New Routing: To create a new routing this button must be pressed. For confirmation of a new routing in the list box a raw line must be visible. Delete Routing: To delete a routing the specific line within the table must be selected and the delete button must be pressed. Copy: Routings can also be copied. To copy a routing the specific line must be selected and the “Copy” button must be pressed. See also “Paste”. Paste: A earlier copied routing line can be inserted by pressing “Paste”. The details of the routing can be adapted afterwards. See also “Arrows – Sequence” Arrows – Sequence The routing machine handles the list in a sequence. Therefore sometimes it is important in which sequence the routing is stored in the list. To change the sequence the green buttons can be used. 11.2.2.3 Connection Properties The connection property is just the name of the routing. If no name is given the ECOTEL® VTMpro provides a automatic generated name. 11.2.3 Port Routing List Contents of the list box: Attribute: Description: Idx Every routing port gets its own index number Name Every port can be assigned a name. The name has to be entered in the “Name” input in the “Port Properties” field. If no name is provided the system assignes its own name. Anyway this name has to be used for further references. Type Shows the type of the specific port. The type has to be selected in the “Type” input in the “Port Properties” field. Destination Specifies the next port the routing machine jumps to if the actual port has finished its job. If the jobs result are not valid the Rerouting is accessed. The destination has to be selected in the “Destination” input in the “Port Properties” field. Rerouting The rerouting provides a alternative if the default destination can not be taken. The rerouting has to be selected in the “Rerouting” input in the “Port Properties” field. CDR For administration reason there can be entered a line in to CDR (Call Data Record) file for every port passed through during the routing. If a entry for the specific port is wanted the check box in the “Port Properties” has to be selcted.
ECOTEL® VTMpro 2005-06-08 Page 56 11.2.3.1 Port Properties The port properties are only visible if a port in the routing list is selected. The lower part of the options belong fix to a specific port type. The upper part is fix. The elements are: Attribute: Description: Name Provides the possibility of giving every port its individual name. If no name is provided the system assignes its own name. Type Every port has its own type. The type influents the behavior of the routing basically. Available Types are: • Channel Group • Routing • Time Routing • Digit Collector • Sim Routing • Audio2Audio • Sms2Email • Email2Sms The detailed functions of the specific types are described below. Destination Provides the possibility to enter the next port to manage after the actual has been done. Rerouting If the default next port, entered in “Destination” has failed a alternative port can be entered. Generate CDR Provides the possibility to generate for each port a individual CDR (Call Data Record) entry in to the cdr.log file. 11.2.3.2 Channel types in detail Every port must be assigned a type. This type can be selected from the “Channel Type” menu: 11.2.3.2.1 Channel Group To receive connections from extern or terminate them to external, the channel group is the necessary type. There can be selected all available ports. This types are displayed in the “Board-Controller-Channel” list view. To add a new port to a empty list the following steps must be done: • Any type of board, controller or channel must be selected in the tree view. • The “Add Board-Controller-Channel” must be pressed. The selection is now visible in the list box.
ECOTEL® VTMpro 2005-06-08 Page 57 • To add another group press the “Add Board-Controller-Channel” again. • To remove a group select it in the list box and press the “Remove Board-Controller-Channel” button. 11.2.3.2.2 Time Routing There is a time depending routing provided. If the actual time of the call is within of any time period defined in the list box the call will be established. Otherwise it will be rejected. To define a new period the add button must be pressed. A selected period can be removed by pressing the remove button. After adding a new period the specific type and the depending dates must be entered. The available types are: Type Settings/Range Description Every Day Starttime: 00:00:00 to 23:59:59 Endtime: 00:00:00 to 23:59:59 The call is permitted independent from the day when the actual time is between start and end otherwise it is rejected Weekday Weekday: Monday to Sunday Starttime: 00:00:00 to 23:59:59 Endtime: 00:00:00 to 23:59:59 The call is permitted when the actual day is matching the configured day and the time is between start and end. Otherwise it is rejected. Month Month: January to December Starttime: 00:00:00 to 23:59:59 Endtime: 00:00:00 to 23:59:59 The call is permitted when the actual month matches the configured month and the time is between start and end. Otherwise it is rejected.
ECOTEL® VTMpro 2005-06-08 Page 58 Date Date: 01.01.1792 to 31.12.8000 Starttime: 00:00:00 to 23:59:59 Endtime: 00:00:00 to 23:59:59 The call is permitted when the actual date is matching the configured date and the time is between start and end. Otherwise it is rejected. Ranged Date Startdate: 01.01.1792 to 31.12.8000 Enddate: 01.01.1792 to 31.12.8000 Starttime: 00:00:00 to 23:59:59 Endtime: 00:00:00 to 23:59:59 The call is permitted when the actual date is between start date and end date and the time is between start and end. Otherwise it is rejected. In the list box can be provided more time ranges. The call must pass all ranges, otherwise it is rejected. Example: The calls may be terminated to the following port weekends and celebration days in may between 7.00 am and 8.00 pm. The following table shows the necessary entries. The call will only be successful if all conditions are fulfilled. Type Data Time Month May 00:00:00 to 23:59:00 Weekday Saturday 07:00:00 to 20:00:00 Weekday Sunday 07:00:00 to 20:00:00 Date 05.05.2005 07:00:00 to 20:00:00 Date 16.05.2005 07:00:00 to 20:00:00 Date 26.05.2005 07:00:00 to 20:00:00 11.2.3.2.3 Routing The routing port provides filtering and manipulating called or calling party numbers. In this way a routing can be achieved. Apply To The following manipulation can be applied to the called party number or the calling party number. The specific number is selected by the radio button.
ECOTEL® VTMpro 2005-06-08 Page 59 List Box In the list box the created conversions are shown. Its just for information and overview: Attribute: Description: Nr. Type Shows the numbering types selected in properties Input Filer Shows the reserved input filter Conversion Shows the applied conversion for the selected filter string Another filter entry can be added by using the “Add” button. In the same way a entry can be removed by selecting it and pressing the “Remove” button. Properties Number Type Within ISDN protocol there is a attribute for called and calling numbers available. The manipulating can be limited to a specific type of numbers. Number Type: Explanation Unknown The number type attribute is not used National The number type within ISDN is set to national format International The number type within ISDN is set to international format Input Filter The input filter provides the possibility to search for strings within a string. Normally there are searched for numbers within a called or calling party number but this function is very universal, so it works also with letters. In conjunction with the “Conversion” function the found strings can be replaced by another string entered in the “Conversion” part. For search mechanism the “Regular Expressions” syntax is used. This is a standardized language for filtering in strings and used in informatics at all. The syntax is as following: Pattern: Description: Example Input Search Expression Found <string> Finds exact the given string 017345678 345 345 . Finds exact one arbitrary sign 01735678 .1.3 0173 ? Finds the precede token cero or once 0173173 173? 173 + Finds the precede token once or more 017335678 3+ 33 * Finds the precede token cero or more times 017355678 74*35* 7355 [ ] Searches one of the signs included in brackets 01735678 [56] 5
ECOTEL® VTMpro 2005-06-08 Page 60 [2-4] One of the signs from 2 to 7, it can also be from a to z 01735678 [2-4] 3 [^] No one of the signs included in brackets 23 [^3] 2 ^ Searches a pattern at the beginning of the line 1234321 1^ 1 (at the beginning) $ Searches a pattern at the end of the line 1234321 1$ 1 (at the end) \ Locks the special determination of the following sign +491735678 \+ + Conversion The conversion function provides the possibility to substitute the found string by another given string. The substitution can be entered in the specific conversion field. If there is no suitable string found the string is set before the dialed string. Example1: For CLI suppression the GSM command #31# can be set before the dialed number. In this case there is no search expression needed and in the conversion field the string #31# must be entered. Example2: The international format in the +49… writing shell be changed to 0049…In this case the + must be replaced by the 00 string. Therefore in the search field the \+ must be entered and in the conversion field the 00. Numbering Type Conversion It´s possible to convert the type of Number of the selected number. Field Action Leave as is Don´t change the type of Number To unknown Change the Type of Number to “unknown” To national Change the Type of Number to “national” To international Change the Type of Number to “international” 11.2.3.2.4 Digit Collector The digit collector provides the option to collect a called party number after a connect. The following routing is based on the post dialed number. Only if there is a valid number entered and the routing fits, then the call will go on. Otherwise it is rejected.
ECOTEL® VTMpro 2005-06-08 Page 61 Attribute: Description: DTMF If the check box is selected, the collector accepts digit only in band in DTMF tone format. Otherwise the digits are expected within the signaling path. Minimum Length The digit collector must decide the moment the number is complete. The minimum length must be always reached before the number can be complete. Maximum Length If the maximum length is reached the collector considers the number as complete Timeout If the count of the numbers is within min and max the number is considered to be complete if the timeout is reached. Stop ID If the number is between minimum and maximum it´s possibel with the “Stop ID” to stop the Timeout. The connection to the destination is started. The Stop ID is not deleted from the Called Party Number! Send DTMF If the check box is selected, the collector sends the number as DTMF-Signal X sekonds after the entry.
ECOTEL® VTMpro 2005-06-08 Page 62 11.2.3.2.5 SIM Routing The SIM-Routing port provides two enhanced functions of SIM routing: SIM Group Routing and Network Routing. Both modes provide routing not to a specific SIM but to a group of SIMs. Searchmode: If calls are pointed to the group there are more modes available how the calls are distributed to the specific SIMs. • First: The first free GSM port within the group is selected. In this case it can happen, that some ports terminate more minutes than other. If there is only one call simultaneously than all calls will be accumulated to the first GSM port. • Rotate: The GSM ports will be rotated. First call is directed to the first port, second to the second ports and so on. The traffic is better distributed than in mode “First”. • Fewest Call Balance: The next call is directed to the next free port with the fewest terminated minutes of traffic. This ensures, that all SIMs have nearly the same load. Reject Cause: If there is no valid routing within the SIM Routing port no matter for which reason and there is no rerouting provided the call is rejected. The cause the call is rejected can be set free from the list. SIM Group Routing In the SMC (SIM Management Center) there is the possibility provided to define groups of SIM with common attributes. Often it makes sense not to route calls to specific GSM ports, but to ports that use SIMs from one group (e.g. SIMs from one provider and the same contract conditions). If SIM Group routing is wanted the appropriated check box must be selected. For more details of creating SIM groups refer to chapter SIM Management Center. Network Routing Network Routing provides the option to route calls to GSM ports that uses the same network. The provider is identified by its PLMN (Public Land Mobile Network), that
ECOTEL® VTMpro 2005-06-08 Page 63 consists of MCC (Mobile Country Code) plus MNC (Mobile Network Code). This code can be also viewed in the information sheet of every GSM channel. There can be provided more codes to cover even roaming conditions if wanted. ATTENTION Some SIMs provide the option of international or even national roaming. When there is roaming active the PLMN differs from the home network PLMN. In this case there will be no calls directed to the affected channels in Network Routing mode if there is only the PLMN from the home network provided. Roaming can be prohibited by entering a PLMN code at the SIM properties within a specific GSM channel. 11.2.3.2.6 Audio2Audio For audio connections the is a coupling of time slots at a specific moment necessary. This coupling is provided by the Audio2Audio port. This port is the terminating port of any routing of voice calls. Timeout: This parameter provides the option to cancel a connection after a specific time. The value is set in seconds. If the parameter is set to –1 then there is no timeout selected. The time starts counting after the Audio2Audio port is reached within the routing and stopped when connect to the b-party is performed. Interconnection: The exact moment of coupling the time slots during establishing a connection can be selected.: • On Dial End: The voice is coupled when dialing has finished and before first alert. • On Alert Indication: The voice is coupled after first alert has been recognized. • On Voice Indication: The timeslots are coupled when there has a in band voice message recognized. Voice is defined a in band message that is not typically a alert or busy signaling before connect. • On Connect Indication: The voice is coupled when there has been recognized a connect at the p-party. In this case any in band information will not be transferred to the a-party. 11.2.3.2.7 Sms2Email In order to receive SMS, convert and send it as email there is a Sms2Email port provided.
ECOTEL® VTMpro 2005-06-08 Page 64 Attribute: Description: Default Receiver In the SMS can be set a receiver email address. If no address can be found within the SMS the ECOTEL® VTMpro sends it to the default receiver address . If whether a address I the SMS can be found nor a default address is given the SMS can not be sent as email! Sender In SMS2Email conversion there is no origin email address given. The sender can set one in the text. If no sender email address is given the ECOTEL® VTMpro sets the default address. If nor a sender address can be found in the email address nor there is a default, the ECOTEL® VTMpro sets the CLI of the origin mobile if provided. Timeout The timeout in seconds can be set different to cero, when there shell be made a new attempt when no confirm is received from the mail server that the email has been sent. 11.2.3.2.8 Email2Sms In order to receive emails, convert and send it as SMS there is a Email2Sms port provided. Attribute: Description: Called party in <SUBJECT> of mail The email that has to be sent as SMS must carry the CLI of the destination. This can be set in the <SUBJECT” of the email Called party in <RECEIVER> of mail or in the <RECEIVER> field of the email. Timeout The timeout in seconds can be set different to cero, when there shell be made a new attempt when no confirm is received from the provider that the SMS has been sent.
ECOTEL® VTMpro 2005-06-08 Page 65 12. Call Generator The Call Generator is a very useful tool for system setup, maintenance or debugging ATTENTION The Call Generator is only able to simulate calls by signaling not by in band voice simulation! New config Load config Save config Upload config Download/ Activate Start call gen Stop call gen 12.1 Overview The Call Generator provides the option to program a list of calls that will be performed. The calls can also be looped back and used for routing tests. To establish a Call Generator entry the following steps must be done: 1. Press the button “New Entry” from the main view. A new entry will be visible in the list box. 2. Give the entry a optionally name in the properties line. 3. Select a channel from the tree list the call shall be generated from. 4. Give the call a Calling Party e.g. for using it in further routings (A-party). 5. Give the call a Called Party (B-party). 6. Give the call a timeout for start the call. If no delay between start call generator and start the specific call is wanted the default cero can be let.
ECOTEL® VTMpro 2005-06-08 Page 66 7. Give the call a max. duration. After the duration time the call generator hooks the call on. 8. If the call shell be performed in period the pause between two repetitions can be set. 9. If there is a extern loop back available (e.g. cross cable on ISDN-E1) then there can be set whether the looped back connection shell be routed or not. 10. Press the “Download/Activate” button at the horizontal icon bar 11. Start the Call Generator by pressing the “Start” button at the horizontal icon bar.
ECOTEL® VTMpro 2005-06-08 Page 67 12.2 Functions in details 12.2.1 Horizontal Icon bar Attribute: Description: New config Creates a new Call Generator configuration. Load config Loads a already established Call Generator configuration from the local machine. Save config Saves a Call Generation configuration. The configuration is saved in XML format on the local machine. Upload config Upload a Call Generator configuration from the ECOTEL® VTMpro in to the maintenance gear for viewing and modification. Download/ Activate Loads a established Call Generator configuration down to the ECOTEL® VTMpro and activates it Start call gen Starts the call generator. Action can be monitored simultaneously at the Connections view or the Layer 2&3 debugging view. Stop call gen Stops the Call Generator. The Call Generator must always be stopped by the user even when the call has already been finished by the B party before it can started again. 12.2.2 Elements from main view Attribute: Description: List Box The list box shows all configured calls. Arbitrary number of calls can be programmed. The calls are worked in the sequence of listing, started with one. The sequence can be manipulated by using the green up/down arrows. New Entry A new call entry is established by this button Remove Entry A selected entry can be removed by pressing this button. Port The call can be given a optionally a individual name. Essentially a channel from the tree view must be selected via the call can be established Calling Party The Calling Party (A-party) number can be set optionally. Called Party The Called Party number (B-party) must be set mandatory. Timeout (ms) The timeout (in milliseconds) for a delayed starting of the call can be set optionally. Duration(ms) The maximum overall call duration (in milliseconds) must be set mandatory. Without a time the call will not be started. Period (ms) The calls can be repeated periodically optionally. If this is wanted a time between two repetitions must be set here. Disable routing… If there is a extern loop back available (e.g. cross cable on ISDN-E1) then there can be set whether the looped back connection shell be routed or not.
ECOTEL® VTMpro 2005-06-08 Page 68 13. Statistics The statistics view provides detailed information over the passed calls. The channel types are colored different because of a better readability. Attribute: Description: Board-Controller-Channel Names the specific channel in the syntax <Board>.<Controller>.<Channel> Incoming Counts the total number of incoming calls Outgoing Counts the total number of outgoing calls Connections Counts the total number of connected calls APartnerDisc Counts the number of calls that have been finished by the A-partner BPartnerBusy Counts the number of calls that have been finished by the B-partner Local Busy Counts the number of calls that could not been routed because of a lack of GSM channels ASR1 Average Seizure Ratio 1: Quotient between successful calls and all calls whereas the calls that are abolished by the A-party before connect are counted as successful calls.
ECOTEL® VTMpro 2005-06-08 Page 69 ASR2 Average Seizure Ratio 1: Quotient between successful calls and all calls whereas the calls that are abolished by the A-party before connect are counted as failed calls. Example: 10 calls, 3 disc by network, 1 disc by A-party ASR1= (10-3)/10*100=70% ASR2=(10-4)/10*100=60% Average duration Displays the average duration in seconds of the calls. Duration Displays the over all minutes that have been terminated through this port. The statistic values can be reset automatically by setting the Automatic Reset parameter from never to daily, weekly or monthly. The statistic can also be retted by pressing the Reset Statistics button.
ECOTEL® VTMpro 2005-06-08 Page 70 14. Connections 14.1 Connections view The connection view provides online the current connection on the VTMpro. To ease the monitoring of the flow the “Show Released Connections” box can be checked on. This function provides the display of the released connections for the time in the box beside set.
ECOTEL® VTMpro 2005-06-08 Page 71 14.2 Logfiles and configuration The “Logfiles and configuration” view provides the administration of call data records. The call data records are separated in cdr.pro for successful calls and cdr_missed.pro for the unsuccessful calls. The files can be uploaded and downloaded between the ECOTEL® VTMpro and the local machine. To refresh the display of the files, e.g. to monitor the files size the “Refresh” button is provided. A selected file can be deleted by pressing the “Delete” button. The files can also be cyclic saved and renamed. The period of doing this can be set by time parameters or maximum contents of lines within the file. The files are renamed from: cdr.pro to cdr_<Year><Month><Day>_<Hour><Minute><Second>.pro Example: When the file is renamed at 29. Mai 2005 at midday the file will be renamed to: Cdr.pro > cdr_20050529_120000.pro The default location the files will be downloaded to the local machine is: C:\documents and settings\<username>\VTMpro_ServiceGear\<Gatewayname or IP address>\..
ECOTEL® VTMpro 2005-06-08 Page 72 15. Online Trace The Online Trace view contents enhanced trace functions that helps the VIERLING technical support and developers retrieving internal problems. This tool is only used on order of this two groups. The user trace functions consists of the following described “Layer 2&3 Trace”
ECOTEL® VTMpro 2005-06-08 Page 73 16. Layer 2&3 Trace The Layer 2&3 Trace provides sophisticated trace functions for retrieving especially GSM and interconnection problems. 16.1 Offline trace and settings The trace options can be set very detailled by the “Trace Mask And Logfiles” panel. 16.1.1 Trace Mask The Trace mask provides the option to switch traces on in a detailed depth. Every channel has there levels of traces. L1 means very low level and detailed trace, L3 means higher abstracter level traces. After setting a trace mask press “Apply Trace mask” to confirm the settings. For the GSM channels there is another settings for L1 trace configuration on boars level. Therefore select: Channels -> GSM.<Board> -> GSM.<Board>.<Channel> -> Layer2Trace ATTENTION Traces always affects a system. Handle switching on traces very carefully. To many traces can paralyze the system in case of too high load. Normally all traces should be switched off.
ECOTEL® VTMpro 2005-06-08 Page 74 16.1.2 Offline Trace There is always offline a tracefile logged name tracelog.trc. The depth of information depends on the set trace mask. The files can be uploaded and downloaded between the ECOTEL® VTMpro and the local machine. To refresh the display of the files, e.g. to monitor the files size the “Refresh” button is provided. A selected file can be deleted by pressing the “Delete” button. ATTENTION To many switched on traces do not only affect the systems behavior in reaction time and performance it will also create huge amounts of data waste that will fill the harddisc space quite fast 16.2 Online trace For viewing traces online a “layer trace” window is provided: To start a trace the “Start Trace” button from the layer trace must be pressed. To stop the running trace the “Stop Trace” button must be pressed. The online trace can also be saved by using the “Save Trace” button. The window is cleared by pressing the “Clear Trace” button. The contents within the trace file is thereby not affected. A limit can be set for the max displayed lines.
ECOTEL® VTMpro 2005-06-08 Page 75 17. CDR – Call Data Records 17.1 General Every call causes a entry into a logfile. The successful calls are logged into cdr.pro, the unsuccessful calls into cdr_missed.pro. The files can be downloaded from the gateway to the local host for further working with. The files are loaded down by following steps: • Logging into the gateway by using ServiceGearGateway. • Changing to the “Connections” view from the vertical icon bar. • Changing to the view “Logfiles and configuration” • Selecting a file from the CDR´s list box. • Pressing the “Download” button • Selecting a folder for the file or using the default folder. • Editing a name and press “Save”. The CDR´s can be renamed automatically by selecting a mode from the “Cyclic Save” menu. The file is therefore renamed at midnight to the name: cdr_<Year><Month><Day>_<Hour><Minute><Second>.pro The CDR files are located at the ECOTEL® VTMpro in the folder: //vierling/var/cdr/.. 17.2 Format The CDR consists of strings separated by comma and terminated by carriage return at the end of the line. No. String Description Example 1 Starttime Start time of the call 19.05.05-12:05:16 2 Endtime End time of the call 19.05.05-12:05:21 3 IncommingPort Is represented by a string. It can be numbers or letters. It belongs to how the incoming port is be named in the routing. The name is given in :Routing->Port Properties->Name 10 (or ISDN) 4 A-party No. The CLI of the A-party 12345 5 Outgoing Port Is represented by a string. It can be numbers or letters. It belongs to how the outgoing port is be named in the routing. The name is given in :Routing->Port Properties->Name 20 (or GSM) 6 B-party No. The CLI of the B-party 01733667123 7 IMSI The IMSI of the SIM card 262014730033372 8 IMEI The IMEI of the GSM module the call has been terminated 520338416255177 9 Call Mode The Mode of the call : 0101 = ISDN 0101 10 Duration The length of the call in seconds 5 11 Billing Info Provides the billing information, that has been sent.
