• VCS Starter Pack Expressway

  Hello, everyone.

  We have donated some equipment to set up a SIP network and there are a few problems.

  For the internal endpoints, we have a customers EX90, C90 and MOVI.  We also have a single Starter Pack Expressway VCS (* without * the dual NETWORK card option).

  For our firewall imagine 3 interfaces: inside, outside and DMZ.  The DMZ has public/Internet IP addresses.  There is no between the inside and the DMZ - NATing it only the NATs as it passes through the external interface (which is of course the interface connected to the Internet).

  So I just have a few addresses here for the love of communication:

  VCS Expressway: 20.0.0.2/25<-- public="">

  Internal endpoint EX90: 10.0.0.2/24

  Internal endpoint MOVI: 10.0.0.3/24

  Again, there are no NATing between 10.0.0.0/24 and 20.0.0.0/25 network.

  Everything works (registered through our VCS) internally.  When we make an external call, tell the customer MOVI, media gets to the external endpoint, but we do not have any media on internal endpoint (not a single UDP packet).  We also noticed the media stream that we send goes directly on the external endpoint (or its VCS) and not through our VCS Expressway.

  Another interesting fact, when we put a little linksys router between the endpoints and our business network (endpoints on the local network, business network on they WAN) everything works and the media we paths through our VCS in the demilitarized zone.  The only thing I can understand is the VCS realize there is now a NAT between the internal endpoint and himself and changes the path.

  I looked through a lot of different documents (VCS base Config Guide, Expressway Starter Pack Deployment Guide, use of the Port IP VCS for Firewall Traversal Deployment Guide, etc.), and none of them that I saw really cover our scenario.  Anyone got any ideas on why the media do not work properly?  I don't have access to a corporate firewall, but I told myself that the UDP stream will never return to us.

  From what I've read in other discussions posted here, it seems that you only need the dual NIC option if your VCS Expressway is coordinated to the Internet (which ours isn't the case).  Is this correct?

  Thank you

  Hi Matthew,

  In addition to the advice given by Tomo and Alok, you could also take advantage of the 'media encryption Mode' area/subarea on the VCS (this is available in X7.2) to force the Express way to the media even for your internal SIP endpoints.

  If you configure for example the "encryption mode Media for the sub-area by default on your VCS-E for 'Best effort', a call between two internal devices registered in the VCS-E would be routed via your VCS-E, media as well as a call between a device internal SIP an external device / remote."

  Hope this helps,

• Duplication of datasets based on input parameters

  I posted this question in the context of the reports of the Oracle, but I think that this is not really a question of relationship Oracle, its more a matter of SQL. I'm on Oracle 9i.
  
  I need to generate a report based on a maximum of 6 input parameters.
  Three of them belong to the client ID # and 3 belong to the Number of Copies that must be printed on the report.
  Settings on clients: P_CUST_ID1, P_CUST_ID2, P_CUST_ID3
  Parameters for the number of copies: P_N1, P_N2, P_N3
  
  So, at some point, there could be a maximum of 3 Customer ID passed to the main request. Here is an example of what might look like the input parameters.
  The user has chosen to enter the values for Customer ID 1 and 2 and left blank for 3 client.
  

  Customer ID1   1001         Number of Copies   2
  Customer ID2   1002         Number of Copies   3
  Customer ID3   ----         Number of Copies   -

  The query that retrieves data looks something like this. The query below is intended to get the client host and addresses of the Office.
  Of course, it is possible that there could be no home or office address or both.
  

  SELECT    c.cust_no,
            c.saln||c.first_name||' '||c.last_name cust_name,
            a.address_type,
            a.street,
            a.city||' '||a.province||' '||a.postal_code city,
            '('||a.tel_area||') '||a.tel_number telephone
  FROM      customer c, customer_address a
  WHERE     c.cust_no = a.cust_no
  AND       c.cust_no IN (:P_CUST_ID1, :P_CUST_ID2, :P_CUST_ID3);

  Based on my query:
  Customer ID 1001 has 3 addresses (House 2 and 1 office)-> the Total number of records = 3
  Customer ID 1002 a 2 addresses (1 House and 1 office)-> the Total number of records = 2
  
  The output should be something like that. I put a copy1 copy2, Copy3 label to show
  How the data will appear for readability.

  I tried to replace the Clause WITH with views online, but have hit a wall. Of course, it is said Table or view does not exist because it cannot find the report_parameters table. Also, I realize that I can't really get the view online at the same level.

  No, report_parameters is used in two places in the solution I posted Saturday. You could code 2 copies of the report_parameters (one inside the cntr, the other to join it), but it should really be. CNTR can rely on two instead, like this:

  SELECT    c.cust_no,

            a.address_type,

              SELECT  :p_cust_no_1 AS cust_no, :p_no_copies_1 AS no_copies  FROM dual  UNION ALL
            SELECT  :p_cust_no_2 AS cust_no, :p_no_copies_2 AS no_copies  FROM dual  UNION ALL
            SELECT  :p_cust_no_3 AS cust_no, :p_no_copies_3 AS no_copies  FROM dual
         )  p               -- End in-line view report_parameters
  ,       (               -- Begin in-linve view cntr
               SELECT     LEVEL     AS n
               FROM     dual
               CONNECT BY     LEVEL     <= GREATEST (:p_no_copies_1, :p_no_copies_2, :p_no_copies_3)
         ) t                    -- End in-line view cntr
  WHERE     c.cust_no           = a.cust_no
  AND       c.cust_no           = p.cust_no
  AND       p.no_copies          >= t.n
  ORDER BY  c.cust_no
  ,       t.n
  ,            a.address_type
  ;
  

  Ensure that: p_no_copies_1,: p_no_copies_2 and: p_no_copies_3 are not NULL; otherwise, GREATEST return the NULL value. Check the settings, you do need lower or equal to 0, or use NVL inside the GREATER expression.

• Problem of integral HP50g expression

  
  

  The problem is flag - 105. You are currently in approximate mode; You must be in exact mode for symbolic work like that.

  Clear indicator - 105, or use the shortcut: If you press and hold the button to the right, then each press of the ENTER key allows you to alternate between approximately and exact mode.  You can see which mode you are at the top of the status area, just to the left of the Center: "=" means you are in exact mode, and "~" means that you are in approximate mode.

  Hope that helps!

• HP50G equations w / complex real Vars &amp; solve for reports of Vars

  Hi guys. I have 2 questions.
  
  1. given an equation with a variable complex and variable real in it, I want to solve for both variables. Here is an example
  
  Given:
  ∠120 has° + jb =-4 + j3
  
  Solve for A and b.
  
  Answer:
  
  A = 8
  b = -3.93

  I know it's possible to solve by hand because A is true and b is complex. But I don't know how to do this on the HP50G because the equation has two variables inside.

  2 it will probably be a bit more complicated. Saw 2 symbolic equations, I want to solve for the report of two variables with respect to the other variables. Here is an example.
  
  Given:
  
  (X Z) / Q + (X - Y) / (X - Y) + R / Q = 0
  / Q (X - Y) = Y/R
  
  Solve for Y/Z depending on X, Q and R
  
  Answer:
  Y/Z = [/(Q+R) R] ^ 2

  I'd be very impressed if anyone can understand these out or already knows how do the following.
  
  Thanks in advance!

  Hello

  (1) :

  It's my approach:

  Settings of the calculator:

  -angle mode: radians (required for the Solver)

  -coord system: rectangular (my choice as it fits x + y * i).

  -Digital and about unchecked

  -operating mode: RPN

  -Flag-27 value complex display that x + y * I

  First angle must be converted to radians, 120 deg = 2/3 * PI radians (PI can be entered as WhiteShift SPC).

  Enter ' (A, ∠2/3 * PI) + B * i =-4 + 3 * I '

  I use 2/3 integers to facilitate the exact mode of address, shortened to ∠ is ALHPA, redshift, 6.

  That the calculator is in rectangular mode, it will be transformed into rectangular.

  You should now have:

  A * COS(2/3*PI) + A * SIN (2/3 * PI) * + B * i =-4 + 3 * I

  Now, press ENTER to duplicate the equation.

  Go to WhiteShift MTH, CMPLX.

  Select RE for the real part:

  A * COS (2/3 * PI) =-4

  Press SWAP (silver arrow)

  Select IM to the imaginary part:

  A * SIN(2/3*PI) + B = 3

  You should now have 2 equations on the stack (the real part of level 2) and the imaginary part in level 1

  You can now put them in a table (2,-> TABLE) and use the Solver to solve for A and b.

  NOTE: when you use real numbers instead of integers, you may use the digital Solver of multiple equations MSLV (NUM. SLV). This requires a set of initial parameters i.e. guess (see Chapter 7 of the great user's Guide or MSLV AUR).

  (2) :

  You cannot resolve Y/Z directly. However, you can solve for and there, Z , then simply ÷ to get Y/Z.

  Level 2: [(X-Z) / Q + (X - Y) / (X - Y) + R / Q = 0 (X - Y) / Q = Y/R]

  Level 1: [Y - Z]

  S.SLV, point 6 or F6 to SOLVE

  Will result in a list or a table that contains solutions for Y and Z depending on X, Q and r. use OBJ-> once or twice to put both equations separately on the stack, then press fracture for Y/Z.

  Note, you can change the representation of the solution by the factor or simplify (best way to find who is to press down arrow money to enter the Equation Editor, select the right side of the eqation then de FACTO or SIMP).

  I hope this helps.

• Load a small program on a HP50g from memory card (SD card)

  Can anyone help me please with loading a close the program on my HP50g calculator from a SD card?

  It will be greatly appreciated. Thank you

• HP50g: HP50g - how to combine the programs and data of some units?

  Like some people on this forum, I have a few pieces of HP50g. On each article there are data and different programs. I'm tired of this mess and want to combine all the programs of all the units in a BASE directory and install the same programs on each unit. As I'll probably do this opreation from time to time in the future, I'm looking for an effective and convenient way to do it. Using the IR ports and programs sending one unit to another would be very slow. Backup on card standard SD also would not be useful in my view (make a backup of each unit, copy on the PC, but what then?).

  Someone on this forum would have hot suggestions to make?

  Hello

  Although you cannot select HOME directory as such, but you can select and copy some or all the elements in the HOME directory and copy only once on the SD card.

  In the FOLDERS menu go to the HOME directory and select the first item and press ENTER, the element highlight will receive a number 1 next to it. In addition to the selection of items with the button ENTER will be number 2, 3 etc. According to him.

  When you have selected all the items you want, COPY and select destination (SD). Unfortunately the built-in FILES does not select the subdirectories of the SD card, but I think that can SDFILER: SDFILER 1.3

• I can not find how to run this program on my HP50g Bessel functions...

  Hello!

  Recently, I buy my HP50g calculator and tried to find and install programs that I need... Solvesys is running, but I can't find how to operate this Bessel function program. I installed it exactly as solvesys (load the lib archive on the calculator and chargue on flash), but I can't find how to run commands, or when they are to crush with. I tried to access the list of orders directly through flash (press the arrow to the right while on archive of lib, then select from the list an eval push) but I get only a result bad argument...

  Can someone guive me a helping hand?

  Hi!, Ahkran:

  Happy new year and welcome to the Forum!

  (1) you need to download the library library 764, BESSEL V1.2, HP50G, in the HOME directory.

  Now, you need to install and stay permanently in memory, in any port (0, 1 or 2). Best if the option port 2 (Flash)...

  

  Now, reset the HP50G, with YOU and key F3 (C)...

  Find the library in Port 2, with orange right shift key and key LIB (2), with name BESSE. If necessary, use the NXT (L) key...

  

  Now press the function key (F1... F6), just below the word BESSE, in your HP50G.

  You have to see...

  

  and with NXT - key...

  Carefully read the instructions for use library 764, the .pdf file, the author.

• HP50G cannot compute certain integrals

  Hi, I have a problem of calculating certain integrals on my calculator.

  Here's an example (the answer should be 1/lambda):

  Type 'version' returns the string: "HP50-C revision 2.08 Copyright HP 2006".

  And "WORM" returns 4.20060106

  Is this fixed in a new release or is it simply not able to do this?

  

  Hi!, Kevin Duke:

  The ultimate version of the ROM is C - 2.15... you can download it from... http://www.HPCalc.org/details.php?id=7097

  Now for your problem, look at this... only if lambda, is the number > 0, a, and real result.

  

  The HP50G, you must put it in CASDIR... REALASSUME (REALA)... 'Λ > 0'.

  Now you must configure FLAGS

  

  Now press on, EVAL key... next step OK (F6) and wait ~ 10 "

  

• Manager HP50g-files and subdirectories on SD card

  I tried to create a directory on SD with FM (File Manager). In the menu soft, there is a 'new' function key, but it does not work (as well as to 'renew', 'command'). Although I could copy a subdirectory of the 'House' at the root of the SD with FM, but copy the files to the directory on SD with FM does not work, can copy and access the files on the SD be only to the root?

  Thank you yoann to dig this thread.
  
  The problem was better explained in my last post. I tried to write a program that would create on SD card a directory and a variable in there and save a DATA in the variable:
  
  For other words say once again:
  
  The battery:
  2. THE DATA
  1 way (for example: DIRECT11/VAR22)
  
  The code example:
  < > > - N < <: 3: N + > > OBJ-> STO > >
  
  The problem is that the example code above works fine but only when the path does not contain a directory (IE path = VAR22)
  
  When the path contains a directory name (for example, DIRECT11/VAR22), a 'OBJ-> error, invalid syntax' message.
  
  If the problem is with "/" sign on behalf of path.
  
  Maybe something I don't know or sysPRL a code would, but I do not know sysRPL wrote.
  
  Unfortunately no one not of HP experts on this forum seem to be interested, or is perhaps too difficult, even for them.
  
  Anyway, one of the weak points in the design of HP50g is bad SD card functionality.

  Andy:

  Assuming that you enter the access/objname string path, try this for storage on the SD card:

  ------< < '3'-------> TAG STO-> >

  If the directory did not already exist, it will be created.  Note that this will only work if an object with this name does not exist at this location.  If this object already exists, you will have to serve before the Save.  A more comprehensive solution would be to try to purge the variable first, catch the error where the object was not already there.  The code would then become

  ------< < '3'---> TAG DUP IFERR PURGE CAN END STO-> >

  I hope that will accomplish what you're looking for.

  As has been said, SDFiler is a nice solution for SD card features that is not integrated to 50 g.

  Hello

  A local variable has 1 main feature: a scope.

  This range means that the variable only exists in this scope...

  A scope is a 'physical' and time stretch (note the quotes around physics, it's because he's not real physics, but virtual physics).

  Expand the 'physical' is the length/area of the program where there is the local variable. This extension from the definition of the local variable until the closure of the program block is more deep where the local variable is defined.

  The measurement of time is the duration of execution of the execution of this program block.

  There is a secondary feature: this is the name and it is the recognition by the system.

  RPL, as in most languages, the basic rules of the gramar program allows a local variable to have a name any. Therefore, at first inseparable from a global variable. The compiler then uses his knowledge of the field of knowledge, when you type a name, if it is to create a local or global variable.

  Until then, there is no problems in the definitions...

  Now, let's look at your program (in essence)

  < < 1 2 - > V1 V2

  < <

  {{V1 'V1'} {'V2' V2}} MENU

  > >

  > >

  When the program runs, it creates 2 MENU items, and then OUTPUTS!

  At the time where your more intimate program stops, local variables are destroyed (normal, follow the rules)...

  HOWEVER, you left a temporary structure that is available to the user (in the menu) which contains references to these variables (which no longer exists)... When you press one of these keys to menu... KaBoom...

  But what that <-syntax stuff?

  Don't forget the 'physical' extension of the scope... It's all good and all... BUT it has some issues.

  Namely, you cannot split your program into small chuncks, stored in various global variables to facilitate programming.

  In most languages, and according to the rules defined above, you may not create a subroutine, using local variables that you plan to have exist in a "time extend" which covers the delivery of the subprogramme. This is true of most programming languages. The reason why you could not create this subroutine is that the compiler would not know/believe these variables are 'in the scope' during the compilation of the program (* see tip below).

  The <-syntax allows this. It allows to force a variable to be compiled as local even outside the physical measure of the scope. But at the time of this call to the local variable, the variable MUST be defined, otherwise... KaBoom!

  This is the heart of your misunderstanding...

  To do what you want, you have 2 possibilities:

  -Use global variables

  -Put a STOP after the MENU statement (you must use TMENU BTW) and a SUITE at the end of execution of each of the menu items.

  I hope this helps!

  Cyrille

  * trick below *.

  The 50 HP has an environment / planning of circuits integrated very neat that lets you do the following to avoid having to type those pesky arrows back.

  Create your top program with your local variable definitions (not necessary of arrows). Just after the definition of the local variable, place a STOP instruction. Run the program.

  Now you can create your SUP program! When you press ENTER and the system compiles your program, these variable EXIST local (you are in their scope of TIME!) and your program will contain local variable rather than global calls!

  However, this will not solve your problem.

• Solve this linear system HP50g

  Hi guys,.
  I am an engineer in electrical engineering and have to solve systems of linear equations on a regular basis, so that the functionality is very important for me. Everything works very well, 95% of the time but sometimes I meet systems that the HP50g doesn't seem to like. For example one below.
  
  I want to solve for x, y, z and one in terms of V
  
  V- 100000 x +is-100000 100000x= 0
  -250000is-V+ 100000x100000z= 0
  -250000z+ 100000one+ 100000y= 0
  a+ 100000-250000z= 0
  
  After these 4 equations is on the stack, I'm them in a vector by pushing {4} in the stack and then by pressing -> ARRY. Then I push the variables I want to solve for the battery, x, y, z and a and a vector of them. Then, I use LINSOLV to solve the system. However, when I do it this way, the calculator gives me an equation for x, an equation for y and 2 equations for z and no equation for s. I'm not sure what I'm doing wrong. Is there another way to do that would give me 4 equations, one for each variable I want to solve for in terms of V?
  
  If my method to solve linear equations is somehow confusing, I basically followed this video

  Thanks in advance.

  Hello

  Do not know exactly how you typed, so I'm being explicit just for some b:

  Notes:

  (1) as an equation is entered, use ' '

  (2) it is preferable to use a comma to separate the real and imaginary parts

  (3) explicit use multiply

  If the entry will look like this:

  '(4,3*X) = (4.7)'

  For this simple equation and assuming that X is defined as an independent variable (reproduced by 'X' in the top middle of the screen), you can use SOLVEVX for this one: (No. 5 in S.SLV menu or F5 if you use soft-keys)

  with "_Approx" uncontrolled, the answer is:

  X = 7/3

  with "vabout" checked the answer is:

  X = (2.333333333,0) (although X is part of the imaginary number, it is himself a real number).

  Kind regards.
