CONFIGURING ALTERNATE ACCESSES

X.25 Accesses

NONSTANDARD DEFAULT TRANSMIT WINDOW SIZE

The number of frames that a DTE can send without receiving an acknowledgment. Using modulo 128, the DTEs can send up to 127 frames without receiving an acknowledgment. Using modulo 8, the DTEs can send up to 7 frames without receiving an acknowledgment. The default value for both modulo 8 and modulo 128 is 2.

NONSTANDARD DEFAULT RECEIVE WINDOW SIZE

The number of frames that a DTE can receive without receiving an acknowledgment. Using modulo 128, the DTEs can receive up to 127 frames without receiving an acknowledgment. Using modulo 8, the DTEs can send up to 7 frames without receiving an acknowledgment. The default value for both modulo 8 and modulo 128 is 2.

NONSTANDARD DEFAULT TRANSMIT PACKET SIZE

The size of a packet that a DTE can transmit. The choice of a packet size must be weighed against the requirements for larger buffers at all the machines that process the packet. Larger packet sizes reduce the opportunity for other devices to share the channel. On the other hand, a larger packet reduces the ratio of overhead fields to user data. The default transmit packet size is 128 bytes.

NONSTANDARD DEFAULT RECEIVE PACKET SIZE

The size of a packet that a DTE can receive. The choice of a packet size must be weighed against the requirements for larger buffers at all the machines that process the packet. Larger packet sizes reduce the opportunity for other devices to share the channel. On the other hand, a larger packet reduces the ratio of overhead fields to user data. The default transmit packet size is 128 bytes.

NONSTANDARD DEFAULT TRANSMIT THROUGHPUT CLASS

Transmit throughput describes the maximum amount of data that can be sent through the network, when the network is operating at saturation. Factors influencing throughput are line speeds, window sizes, and the number of active sessions in the network. The default value is 19,200 BPS.

NONSTANDARD DEFAULT RECEIVE THROUGHPUT CLASS

Receive throughput describes the maximum amount of data that can be received through the network, when the network is operating at saturation. Factors influencing throughput are line speeds, window sizes, and the number of active sessions in the network. The default value is 19,200 BPS.

X.25 CHARGING-RELATED FACILITIES

These facilities are used to place charging-related restrictions upon incoming and outgoing X.25 calls.

INCOMING CALLS REVERSE CHARGING

This parameters allows you to choose whether the DTE (the CyberSWITCH) should accept incoming X.25 calls that request reverse charging. The default configuration is to not allow incoming X.25 calls to request reverse charging.

OUTGOING CALLS REVERSE CHARGING

This parameters allows you to choose whether the DTE (the CyberSWITCH) should be able to request reverse charging for outgoing calls. The default configuration is to not allow outgoing X.25 calls to request reverse charging.
