Customizing OAM configuration files

To configure and start the boards, specify configuration parameters in the board keyword file. Then reference the board keyword file for each board in another file, the system configuration file. When you run oamsys, it creates a record for each board in the OAM database and stores the parameters and values of the board. oamsys then starts the board, configured as described in the database.

The following illustration shows the relationship between the board keyword files and the system configuration file:

Modifying sample CG board keyword files

The DLCP software provides several sample board keyword files that demonstrate how to use NMS OAM board keywords for particular types of system configurations. Edit a sample board keyword file to specify appropriate configuration information for your system, including the line interface type. For detailed information about customizing CG board keyword files, refer to the board's hardware documentation. The following table lists the DLCP sample board keyword files:

Board keyword file

Board type

Description

cg6gr303.cfg

CG 6000 or CG 6000C

Configuration file for T1 interfaces used on GR303 systems.

cg6v5.cfg

CG 6000 or CG 6000C

Configuration file for E1 interfaces used in V5.2 systems.

cg61gr303.cfg

CG 6100C

Configuration file for T1 interfaces used on GR303 systems.

cg61v5.cfg

CG 6100C

Configuration file for E1 interfaces used in V5.2 systems.

cg65gr303.cfg

CG 6500C

Configuration file for T1 interfaces used on GR303 systems.

cg65v5.cfg

CG 6500C

Configuration file for E1 interfaces used in V5.2 systems.


CG board settings specified in the board configuration files include:

Configuring T1 or E1 line interfaces

To configure the T1 (for GR303) or E1 (for V5) interfaces, ensure that the following keywords display in the board keyword file:

OAM keyword

GR303 (T1) values

V5.2 (E1) values

Specifies...

NetworkInterface.T1E1[x].Type

T1

E1

Trunk type for each trunk on the board.

NetworkInterface.T1E1[x].Impedance

DSX1

G703_120_OHM | G703_75_OHM

Type of cable connecting a CG board to the telephone network.

NetworkInterface.T1E1[x].LineCode

AMI | B8ZS | AMI_ZCS | AMI_BELL |AMI_DDS| AMI_GTE

HDB3 | AMI

Ones density maintenance method used on the trunk line to maintain a clear channel transmission.

NetworkInterface.T1E1[x].FrameType

ESF

CEPT

T1 or E1 trunk framing format for the current board(s) or current trunk(s).

NetworkInterface.T1E1[x].SignalingType

CAS

RAW

How voice and signaling information is routed to and from the E1 or T1 trunk and DSP resources.


For all keywords in the table, x is a 0-based trunk number or range of trunk numbers as defined by NMS OAM. For CG 6000 or CG 6000C boards, x can be an integer between zero and three. For CG 6100C or CG 6500C boards, x can be an integer between zero and 15.

Note: When setting the NetworkInterface.T1E1[x].Type keyword, you must specify all trunks as either T1 trunks or E1 trunks. Do not specify more than one trunk type.

For more information, refer to the T1 and E1 trunk channels section in this manual.

Creating a system configuration file

When your board keyword file(s) are complete, create a system configuration file that describes the overall configuration of your system and references the board keyword file for each board. The system configuration file is typically named oamsys.cfg. Refer to the NMS OAM System User's Manual for information on the syntax and structure of oamsys.cfg.

Note: You can use the oamgen utility (included with the NMS OAM software) to create a sample system configuration file for your system. The system configuration file created by oamgen may not be appropriate for your configuration. You may need to make further modifications to the file before running oamsys to configure your boards based on the file. For more information about oamgen, refer to the NMS OAM System User's Manual.

When necessary, you can modify the CG board bus and slot number to include multiple boards in a system. Each board entry in the system configuration file must contain the following keywords:

Keyword

Description

Product

Board product type

Number

Logical board number

Bus

PCI Bus number of the CG board

Slot

PCI Slot number of the CG board


To obtain CG board bus and slot numbers, run the pciscan utility. For more information about pciscan, refer to the NMS OAM Service System Users's Manual.

After you customize the individual board keyword files and create the system configuration file, run the oamsys utility to configure the boards as specified in the configuration files. When you run the oamsys utility, it creates NMS OAM database records based on the contents of the specified system configuration file and board keyword files. It then directs NMS OAM to start the boards and configure them according to the specified parameters.
