## 6402
Activate I/O ports ?

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 Initiate I/O ports) 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 Initiate I/O ports) 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.
