COMMENTS
In Germany (1TR6), 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, 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.
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.
Do not change the factory settings.
1: 64 kbps calling is indicated in the Bearer
Capabilities, but communication is at 56 k. Use
this bit if the machine is connected to a network
which does not accept a 56 kbps data transfer
rate as a bearer capability.
Do not change the factory settings.
