3: ADCCP NRM DLI Functions
DC 900-1317J 55
The usProtXParms[0] field is used to specify the station ID. The station ID field is speci-
fied in most control packets. However, under some conditions, the client must specify
station number zero. This occurs when the client:
• enables a physical link
• disables a physical link
• reconfigures a link
• requests link statistics
• signals an idle link
• sets the maximum data size
• requests software version data
The usProtXParms[1] field is the data size, which specifies the number of bytes actually
used in the transparent data area. The data size may be any value from zero up to and
including the maximum allowable data size (see Section 4.1.1 on page 85).
The transparent data area, if present, contains additional information required to com-
plete the control packet. Data area contents are discussed in Section 3.4.1 through
Section 3.4.34.
3.4.1 DLI_PROT_SEND_STATION_INIT Packet
This packet is valid only if the client has enabled ADCCP option 5 (see Section 3.4.20.2)
for the specified station. The client must specify the
usProtCommand field
(
DLI_PROT_SEND_STATION_INIT), the usProtXParms[0] field (station ID), and the
iProtModifier field.
