SimWriter Testing Dial Plan for the Cisco PGW 2200

Document ID: 48120

Updated: Jun 07, 2005

   Print

Introduction

While you create a dial plan and then test it out, there is no way to verify how a call runs through a dial plan on the Cisco PGW 2200. At this time, you need to make a test call and run a full MDL trace on the call. When you look at the traces, they are verbose and complicated to understand. For this reason, the SimWriter under the /opt/CiscoMGC/bin directory is an easier trace to understand. The Translation Verification tool provides you with a means to understand how calls are processed based on your system's dial plan. This tool creates a simulation of a call that is processed by the dial plan.

Prerequisites

Requirements

Cisco recommends that you have knowledge of these topics:

Components Used

The information in this document is based on the Cisco PGW 2200 SoftSwitch.

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.

Conventions

Refer to Cisco Technical Tips Conventions for more information on document conventions.

Cisco PGW 2200 SimWriter

In order to view the latest SimWriter help options, go to the /opt/CiscoMGC/bin directory and run either the SimWriter command or the simWriter –help command on the command line. The -help parameter provides you with the help description of each argument. This document only focuses on some of these arguments. If you want to use this in a graphical situation, run the MGC_Toolkit command under directory /opt/Toolkit/bin via X-windows. This contains a built in Translation Verification section. Also, use the SimWriter command.

Currently, when you issue the ./MGC_Toolkit command under the /opt/Toolkit/bin directory, you receive this information:

Select the Translation Verification option to display this window:

Table 1: SimWriter Help Output Information

Option String Argument Argument Type Description
-tgnum Trunk Group Number 4 digits This option is mandatory. It specifies the trunk group number that the call comes in on. The specified trunk group is then used to find out all the stored information about the customer and their preferences from the .dat files.
-full <none> <none> Indicates to SimWriter and callver that a full trace is desired. Under this mode, a more detailed trace is printed. See the Callver Output section for a detailed description of this format.
-diag <none> <none> Indicates to SimWriter and callver that a diagnostic trace is desired.Under this mode all the results are printed, but all the table information is left out. See the Callver Output section for a detailed description of this format.
-isdpn ISDP Preference Enumerated Code Digits Specifies an ISDN preference to use while you select an outgoing route. This preference is the one that is included in the initial address message. There is an additional route preference that is picked up from the .dat files using the originating trunk group. The possible values are listed in Table 2.
-cdnoa Nature of Address (NOA) of the Called Party Digits An enumerated number that represents the Called Party's NOA. This is the number that corresponds with the values of the NOAs in the Call Context. See Table 3 for NOA types and their integer values.
-cdnpi Called Party's Numbering Plan Indicator (NPI) Digits An enumerated number that represents the NOA of the Called Party. This is the number that corresponds with the values of the NPIs in the Call Context. See Table 4 for NPI types and their integer values.
-cdpn Called Party Number String of digits This is the Called Party Number. Currently, the dial plan only supports digits 0 through 9. Therefore, no hex digits are allowed.
-cgnoa NOA of the Calling Party Digits An enumerated number that represents the NOA of the Calling Party. This is the number that corresponds with the values of the NOAs in the Call Context.
-cgnpi NPI of the Calling Party Digits An enumerated number that represents the NOA of the Calling Party. This is the number that corresponds with the values of the NPIs in the Call Context.
-cgpn Calling Party Number String of digits This is the Calling Party Number. Currently, the dial plan only supports digits 0 through 9. No hex digits are allowed.

SimWriter Usage Example

In this example, a TDM hairpinning call is made via the PGW 2200 to the NAS. First, look via SimWriter in order to see if the Cisco PGW 2200 dial plan reports any errors at the moment that the PGW 2200 is incorrectly provisioned.

Note: Due to some modification on SimWriter, Cisco recommends that you upgrade the PGW to the latest patches. Check the for additional information. Also make sure you see engine.SysVirtualSwitch = 1 in the XECfgParm.dat file in the /opt/CiscoMGC/etc directory and that the CALLVER*.mdos are installed under the /opt/CiscoMGC/lib directory. Refer to Cisco bug ID CSCee18831 (registered customers only) which addresses how SimWriter should be able to capture all property driven changes.

This example removes the first two digits from the B-number and reroutes the call back out on route51. The BMODDIG result type has a "dw=1" and "dw=2", which indicates to start removing beginning with the first digit of the B-number, and deleting the first two digits [dw=2].

numan-add:resultset:custgrpid="sw01",name="rset51" 

numan-add:resulttable:custgrpid="sw01",name="strip51",resulttype="BMODDIG",
dw1="1",dw2="2",setname="rset51" 

numan-add:resulttable:custgrpid="sw01",name="route51",resulttype="ROUTE",
dw1="rtgrp51",setname="rset51"

After you add the BMODDIG and ROUTE mml commands, and issuing the mml commands prov-cpy or prov-dply, you can check the configuration using the prov-rtrv and numan-rtrv commands.

route51       ROUTE         rtgrp51    0       0     0         0

In this case, you can either make a test call and check the correct working or, check the output of the SimWriter to see if any error messages have been reported.

If you do not remember the simWriter argument, use a prompt interface instead of the command-line as this output shows:

mgcusr@PGW2200%simWriter -prompt
Enter the trunk group number (4 Characters)     : 51
Enter the ISDN preference (0-2 [Default 1])     : 
Enter the Called party's NOA (1-47 [Default 4]) : 4
Enter the Called party's NPI(0-9 [Default 1])   : 1 
Enter the Called party number                   : 5151929729
Enter the Calling party number                  : 9727

You can also choose to directly use the command-line as this output shows:


!--- This command  has been wrapped to the second 
!--- line for spatial reasons.


mgcusr@PGW2200% simWriter -tgnum 51 -isdnp 0 -cdnoa 4 -cdnpi 1 -cdpn
