COMMENTS
Change this bit to 0 if you want to have a protocol
dump list of the last communication only.
This bit is only effective for the dump list #2 (D +
Bch1).
Do not change the factory settings.
COMMENTS
Do not change the factory settings.
This bit is used in Germany; set it to 1 for German
PTT approval tests.
1: RCBCTR counts consecutive R:RNR signals. If
the counter reaches the value of N2, the link is
disconnected.
Do not change the factory settings.
COMMENTS
Do not change the factory setting.
This bit is normally 0. However, some networks
may require a fixed LCN. In such cases, this bit
should be 1, and you may have to set a different
value for the LCN using G4 Parameter Switch 0A.
The Protocol ID is in the CR packet.
Do not change the factory settings.
COMMENTS
When the CR packet format matches ISO8208
protocol, some networks may require this bit to be
set at 1.
This bit is only effective if bit 0 of G4 Parameter
switch 06 is at 0.
This is only for packet networks. The CR packet
should contain the rx side's DTE address, but
does not have to include the tx side's; it can
include it as an option.
Do not change the factory setting.
