ON-NODE DEVICE DATABASE CONFIGURATION ELEMENTS

GENERAL CONFIGURATION ELEMENTS

DEVICE NAME

A1 to 17-character, user-defined case-sensitive name that uniquely identifies the device to the system administrator. The name may contain any displayable ASCII character except the quote “” character. This name is displayed on the connection monitor window when the device connects to the system.

ISDN CONFIGURATION ELEMENTS

Note: These elements are configured for ISDN devices and devices over dedicated connections only.

ISDN LINE PROTOCOL

The available line protocols for ISDN access devices. Possible line protocols include:

•PPP

Point-to-point protocol. Allows device to use TCP/IP. The default configuration value.

•HDLC Bridge

HDLC encapsulated bridge frames are used to connect the system to remote bridges. It is the simplest line protocol, using a standard HDLC frame.

•IP Host (RFC 1294)

RFC 1294 provides a simple security exchange at connection time, along with an encapsulation method for IP datagrams. RFC 1294 devices are not interoperable with the CSX1200, CSX1000, and CSX150 products.

BASE DATA RATE

Only used for Dial-Out. This value represents the throughput on a B-channel or pre-ISDN link connecting the CyberSWITCH to a device. The data rate can be specified as either 56,000 or 64,000 bps. The default configuration for the base data rate is 64,000 bps. If 64,000-bps connections to the device are not possible, this value should be set at 56,000 bps.

INITIAL DATA RATE

Only used for Dial-Out. The initial data rate determines the bandwidth that will be attempted when opening the first wide area connection. This provides you with a mechanism to request that a group of parallel connections be made to a remote device rather than a single connection. This will allow data to begin to flow at greater rates without waiting for the Throughput Monitor to detect an overload condition. Calls will be made until an additional call would exceed the configured value. The value is configured as a number from 2,400 to 1,024,000. For example, if you have configured the Base Data Rate at 64 Kbps, and the Initial Data Rate at 256,000, the system would attempt to initially use four calls (connections) running in parallel (256,000 / 64,000 = 4). The default configuration for the Initial Data Rate is 64,000 bps.

MAXIMUM DATA RATE

The Maximum Data Rate is used to limit the total number of channels that can be committed to a single device (logical connection). This sets an upper boundary for line and capacity utilization. This upper boundary allows you to keep one remote device from crowding out other devices and using an unfair share of available resources. This parameter is enforced on inbound and outbound
