Application Programming Interface

Forcing LOS: suni4x622SOHForceLOS

When the enable flag is set, this function forces a loss of signal condition in the data stream. When the enable flag is not set, this function resumes normal processing.

Prototype

Inputs

Outputs Returns

INT4 suni4x622SOHForceLOS(sSUNI4x622_HNDL deviceHandle, UINT1 channel, UINT2 enable)

deviceHandle	: device handle (from suni4x622Add)
channel	: channel number
enable	: flag to start/stop a loss of signal condition
None

Success = SUNI4x622_SUCCESS

Failure = SUNI4x622_ERR_INVALID_DEVICE_STATE

SUNI4x622_ERR_INVALID_DEV

SUNI4x622_ERR_INVALID_CHAN

Valid States	SUNI4x622_ACTIVE, SUNI4x622_INACTIVE
Side Effects	None

4.6Line Overhead (LOH)

The Line Overhead section provides functions to configure and monitor the line overhead on both the receive and transmit sides. Read / Write access is given to the APS bytes (K1 and K2) and most other overhead bytes. Signal failure and signal degrade can be monitored. For diagnostic purposes, errors can be introduced in the line overhead bytes. Additional functions are provided to automatically insert line RDI and line AIS.

Configuring SF Error Monitor: suni4x622LOHSFCfg

This function configures the Signal Failure BERM automatic monitoring of line bit error rate threshold events.

Inputs

Outputs Returns

INT4 suni4x622LOHSFCfg(sSUNI4x622_HNDL deviceHandle, UINT1 channel, sSUNI4x622_CFG_SF *psfcfg)

deviceHandle	: device handle (from suni4x622Add)
channel	: channel number
psfcfg	: (pointer to) SF configuration block
None

Success = SUNI4x622_SUCCESS

Failure = SUNI4x622_ERR_INVALID_DEVICE_STATE

SUNI4x622_ERR_INVALID_DEV

SUNI4x622_ERR_INVALID_CHAN
