When you make changes to the configuration files, you need a text editor or word processor that provides the capability to save the files as DOS ASCII text. For example, the DOS editor EDIT.COM is a valid text editor in DOS, and the Windows Notepad is a valid editor in Windows. Follow the procedures outlined below to make a backup copy of the original file.

Step 1 At the DOS command line, enter the following command:

COPY NET.CFG NET.OLD

Step 2 Launch your text editor program and open the appropriate configuration file.

Step 3 Modify the NET.CFG configuration file.

Step 4 Save the configuration file and exit your text editor.

Step 5 If you are running Windows or Windows for Workgroups, exit Windows completely.

Step 6 Unload the Cisco 200 by running DCONNECT.BAT. At the DOS command line, enter the following command:

DCONNECT

Step 7 To make the changes take effect, run CONNECT. BAT to start the router(s). At the DOS command line, enter the following command:

CONNECT routername

Modifying the ISDN200.CFG File

The ISDN200.CFG file contains most of the information required to manage the ISDN connection. This file is automatically created when you install the Cisco 200 software.

You might need to modify the ISDN200.CFG file after you initially install the Cisco 200 software. For example, you may want to enable IP or bridging; use the Cisco 200 in Windows; or add, delete, or modify remote locations.

To modify the ISDN200.CFG file, use any text editor or word processor that will allow you to save the file as DOS ASCII text.

The ISDN200.CFG file is divided into three sections:

Local Configuration—Specifies the configuration of the Cisco 200 workstation.
Connection Router Configuration—Contains the parameters of the default connecting router with which the PC will communicate.
Additional Connection Router Configuration(s) (Optional)—Contains the parameters for additional connecting routers. These parameters are arranged in the same order as those for the first connecting router.

Sample ISDN200.CFG Files

Two example files, ISDNCFG1.EXP (illustrating use outside North America) and ISDNCFG2.EXP (illustrating use within North America), are copied to your Cisco 200 directory when you install the Cisco 200 software.

The following example shows the ISDNCFG2.EXP file for the North American ISDN protocols:

ISDN200.CFG Parameters

The parameters listed in the ISDN200.CFG file, along with the examples used throughout this manual, are outlined in Table B-1 below and explained in the text that follows.

Table B-1: ISDN200.CFG Parameters

Section	Parameter	Example
Local Configuration	Name	NAME = MyHomeOffice
	Own MSN¹	;OWN MSN = *
	Accepted MSN	ACCEPTED MSN = *
Connecting Router Configuration(s)	Name	NAME = HEADQUARTERS
	Password	PASSWORD = Secret
	Dialnumber	.914085553000

	PPP Callback	PPP_CALLBACK = TRUE

¹MSN = multiple subscriber number

Local Configuration Parameters

Name—This is the name of the local Cisco 200. In these examples, this is defined as "MyHomeOffice."
Own MSN—This optional parameter is used for outgoing calls only on certain PABX systems. If you do not enter a number here, the part of the dialnumber after the last hyphen (which specifies your own dialnumber) is transferred as the calling party number during an outgoing call.

: Some PABXs do not specify the entire dialnumber as their own calling party number during an outgoing call. Therefore, you can enter in this field the entire MSN to be transmitted or the entire dialnumber with terminal selection digit to be transmitted.

Accepted MSN—This parameter is important in some PABXs for inbound calls. It controls which multiple dialnumbers on the S0 bus (Euro-ISDN) address the relevant ISDN Adapter. If you are using only one ISDN Adapter, do not change the default setting, which is an asterisk (*).

: If * (asterisk) is entered in this field, the workstation reacts to all authorized inbound calls with the service identification data transfer rate (64 kbps).
: If this field is empty, the workstation automatically uses the last block (after the hyphen) of its own dialnumber for the MSN comparison (Euro-ISDN).
: When using the DSS1 Protocol, enter the MSN specific to your workstation's ISDN Adapter.

Connecting Router Configuration Parameters

Name—This parameter specifies the name of the remote router; the name can consist of up to 12 characters. You can use any alphanumeric character and the underscore (_) character. Enter the same string in the square brackets above the Name parameter as that specified in the Name parameter.
Password—This parameter specifies your CHAP password for authentication by the remote router.
Dialnumber—This parameter specifies the dialnumber for the connecting router.

: The dialnumber parameter contains (as a single string) all the numbers that must be dialed to form a connection to the connecting router. The dialnumber string should include, as applicable, the following codes or numbers:

Service—This parameter specifies the line speed for the connection to the remote router. Use a leading semicolon (;) to comment out the incorrect parameter (in our examples, DATA56 is commented out).
Inactivity Timeout—This parameter controls the number of seconds that the Cisco 200 software will wait during periods of non-use before disconnecting the ISDN connection. This feature can be used to control costs.

Note

: When two stations with different values for this parameter are communicating, the smaller value is automatically used. If this parameter is enabled on only one station, the inactivity timeout is used according to the value set on that station. The default setting is 20.

IPX—To enable IPX routing, use a leading semicolon (;) to comment out this line.
IP—To enable IP routing, use a leading semicolon (;) to comment out this line.
MLB—To enable MAC Layer Bridging, use a leading semicolon (;) to comment out this line.
Indicated Dialnumber—Enter the dialnumber your remote router will be expecting if a call like the one defined below is received. You can specify several dialnumbers for the same remote router.

Note

: This parameter is used if the remote router's dialnumber to be called is different from the remote router number supplied by the network. It is also used when calls are received at different times from remote routers using different line numbers.
: If you do not know which number the network will supply to your remote parameter, you can set this parameter to IGNORE. All incoming calls will be accepted, but the caller will be identified via a Welcome Packet exchanged between the workstation and the router at the beginning of every connection.

Note

: If you go through a passive connection establishment (reestablish after a transparent connection deestablishment from the router), you can use the utility provided to ask which number was indicated on the network side and enter it instead of IGNORE in your ISDN200.CFG file.

PPP Multilink—This parameter specifies whether to use the second ISDN B channel dynamically or permanently.

: If you use the second B channel dynamically, the Cisco 200 software automatically raises the second line when it detects that a large amount of data is being transferred, and lowers the line after traffic decreases. To use the second B channel dynamically, enter the following string in the ISDN200.CFG file:

PPP_MULTILINK=DYNAMIC

: If you use both B channels all the time, you can improve your system's response time but potentially incur higher line costs. To use both B-channels all the time, enter the following string in the ISDN200.CFG file:

PPP_MULTILINK=STATIC

Channels—This should be set to 2 if you are using PPP multilink or 1 if you are not using PPP multilink.
PPP Callback—This parameter specifies that calls outgoing from the Cisco 200 will connect just long enough to request the router to call back. This allows the bulk of the connection costs to be billed to the connecting router and provides an extra layer of security because the connecting router will only dial a previously configured number to reach the authenticated user.

: To enable PPP callback, enter the following string in the ISDN200.CFG file:

PPP_CALLBACK=TRUE

: To disable PPP callback, enter the following string in the ISDN200.CFG file:

PPP_CALLBACK=FALSE

: Alternately, to disable PPP callback, you may comment out the statement PPP_CALLBACK=TRUE in the ISDN200.CFG file using a semicolon, as in the following example:

;PPP_CALLBACK=TRUE

Modifying the NET.CFG File

The NET.CFG file contains information required to manage the protocols running over the ISDN connection. This file is automatically created when you install the Cisco 200 software.

You may need to modify the NET.CFG file after you initially install the Cisco 200 software. To modify the NET.CFG file, use any text editor or word processor that will allow you to save the file as DOS ASCII text.
