SM
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 6 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.
Do not change the factory setting.
0: If a new R:CSS is received, the machine sends back
S:RSSN.
1: If a new R:CSS is received, the machine sends back
S:RSSP. Set this bit to 1 for German PTT approval tests.
Do not change the factory settings.
In most countries (including Europe), this should be
disabled.
This should be kept at 5 s (both bits at 0) for normal
operation. However, you may have to change this during
PTT approval tests.
Set this bit to 1 for French PTT approval tests.
Do not change the factory settings.
0: Some DSUs may not reply to the INFO1 signal with
INFO2, if there is noise in the INFO1 signal accidentally.
Try changing this bit to 0, to resend INFO1 before the
machine displays "CHECK INTERFACE".
