4.8 Payload Processor

The Payload Processor performs both ATM and PPP processing.

Setting Payload configuration pa rameters: suni4x622PyldCfg

This function sets up the minimum and maximum packet length, cell header and mask for
packet/cell payload configuration.
Prototype INT4 suni4x622PyldCfg(sSUNI4x622_HNDL deviceHandle,
UINT1 channel, sSUNI4x622_CFG_PYLD *ppyldcfg)
Inputs deviceHandle : device handle (from suni4x622Add)
channel : channel number
