data.setportsc.rcode

This field is used for actions ZcDSC_ALL_PARMS, ZcDSC_CFG_MODE,

ZcDSC_BAUD_RATE, ZcDSC_PORT_MODE, ZcDSC_SET_TIMESLOTS and

ZcDSC_SET_SUBC_SPECS only. Values are:

1 - Use configuration in interface table

2 - Use data in field data.setportsc.ptcfg

data.setportsc.ptcfg

Pointer to the port and subchannel configuration data of which the data

structure zptcfg_t is defined in /opt/acc/include/zcom/zcomsys.h.

data.setportsc.ptcfg->ptcnfg

Port configuration data (32 bits) which is used for actions

ZcDSC_ALL_PARMS, ZcDSC_CFG_MODE, ZcDSC_BAUD_RATE and

ZcDSC_PORT_MODE only. See the Port Configuration section for the format

of the configuration data (data.setport.cnfg field).

data.setportsc.ptcfg->ptinfo.subchb.tmsl[ ]

Timeslot assignment array: used for actions ZcDSC_ALL_PARMS or

ZcDSC_SET_TIMESLOTS only. Up to 32 timeslot assignments are allowed.

Each element of the array is indexed by the timeslot number. That is, timeslot

0 is in tmsl[0], timeslot 1 is in tmsl[1], etc. For action ZcDSC_ALL_PARMS,

all timeslots are configured. For action ZcDSC_SET_TIMESLOTS only

timeslot entries with the UPD bit set are configured. The timeslot definition

for each element in the array is shown below:

UPD: The Update bit is used with the ZcDSC_SET_TIMESLOTS action to

identify timeslots which are to be configured. Timeslots with the UPD bit not

set, are unaffected by the ZcDSC_SET_TIMESLOTS action.

Detailed descriptions of the TTI, RTI, Transmit and Receive subchannel

numbers, and the Transmit or Receive fill masks, can be found in the

Siemens MUNICH32 data sheet in Section 4.2.4 Time Slot Assignment.

A TTI (Transmit Timeslot Inhibit) bit value of ‘1’ causes the transmit timeslot

to be placed into tristate. The data is not destroyed but sent in the next

non-tristated timeslot allocated to this subchannel.
