However, some networks may require the
machine to add this ID. Only in this case should
this bit be at 1.

(1TR6) (CNET)
In Germany (1TR6) and France (CNET), a time
delay to answer a call is required.
In other countries, use this switch as follows:
If the machine is connected to the same bus from
the DSU as a model K200 is connected, the
machine receives most of the calls because the
response time to a call is faster than the K200.
If the customer wants the K200 to receive most of
the calls, adjust the response time using these
bits.
If the customer does not want one machine to
receive most of the calls, use subaddresses to
identify each terminal.
2
Action when receiving [SETUP] signal containing user-specific callrd party subaddress
0: Ignores the call 1: Receives the call
Normally, the 3rd octet of called party subaddress
information in the [SETUP] signal is set to NSAP.
However, some networks may add “user-specific”
subaddress to the [SETUP] signal (UK), and the
result of this is that the machine won't answer the
call if a subaddress is specified.
So, change this bit to 1 to let the machine receive
the call if the machine is connected to such a
network.
