6401
Initiate I/O port
This command is used to determine which line
position(s) is (are) used for the communication
channel(s). The stated line position shall be equipped
with one board with V.24-interface ( AUX or CPU-D ).
Note that the individual number 1 on CPU_D has a
V.22-interface .
The line position is entered as : ppiii
with pp = board position ( 00-63 )
iii = valid individual
ppiii = Space ( means channel is switched off )
If both communication channels are switched off there
is no in/output and furthermore the entire call logging
function is shut down.
NOTE: Before output of call data can take place,
the signaling method via the V.24-
interface on the board ( AUX,CPU_D ) at
the stated line position must be
determined, and thereafter the
communication channels can be
activated/deactivated and the format
may be selected in accordance with the
desired operation, see command 6402 .
6402
Activate I/O port
The command is used to select the type of operation
for in/output of call and hotel data.
a. One external unit for storage of data from
ASB150.
b. One external unit for transmission of hotel data
to ASB150.
c. Two external units for storage of data from
ASB150. Output occurs in parallel at both units.
d. Two external units for storage of data from
ASB150. Output normally occurs at one of the
units, but will be switched automatically to the
second unit, if the first unit develops a fault
that prevents output at it.
e. Two external units:
- one for storage of data from ASB150.
- one for transmisison of hotel data to ASB150.
For the types of operation listed above the following
applies:
a. The initiated communication channel (see 6401)
shall be active.
b. The initiated communication channel can be
active or passive (lacks significance).
c. Both communication channels shall be active.
d. The communication channel that is to be used
as first choice shall be active and the second
choice channel passive. If both channels are
passive, there will be no output.
e. The initiated communication channel (see 6401)
for storage of data from ASB150 shall be active.
NOTE: If communication with external/peripheral
equipment is interrupted for some reason
or other, an attempt can be made to
restart communication by first setting the
channel to passive, and thereafter setting
it to active again. This procedure includes
the risk that some data can be lost.
It is also possible to specifiy that automatic attempts to
try to reactivate the channel shall take place after a
stipulated time following a fault. If a previously passive
and fault-marked channel is activated, it is possible
that some data are lost.
