T.30 Session Error Report, +FAXERR
Class 2.0/2.1 not supported
Class 2 +FAXERR
Read syntax: > +FAXERR= <table value>, read only
Valid values: 0–255; see Table 3.5 for meaning
This read only parameter indicates the cause of a hang-up. Table 3.5 shows the valid
values for this parameter as well as the meaning of each value. +FAXERR is set by
the modem at the conclusion of a fax session. The modem will reset this to 0 at the
beginning of Phase A off-hook time.
Minimum Phase C Speed, +FMS
Class 2.0/2.1 +FMS
Write syntax: +FMS=BR
Valid values: 0–5, in BR subparameter codes
Default value: 0 (V.27ter @ 2400 bit/s)
This optional parameter limits the lowest negotiable speed for a session. It is useful
for limiting the cost of a transmission by requiring a minimum transmission speed. If a
facsimile cannot negotiate to a minimum speed, it performs an orderly disconnect.
The units are the same as those defined for the BR Bit Rate subparameter as defined
in Table 3.6 in this manual.
Class 2 +FMINSP
Write syntax: +FMINSP=BR
Valid values: 0–5, in BR subparameter codes
Default value: 0 (V.27ter @ 2400 bit/s)
This optional parameter limits the lowest negotiable speed for a session. It is useful
for limiting the cost of a transmission by requiring a minimum transmission speed. If a
facsimile cannot negotiate to a minimum speed, it performs an orderly disconnect.
The units are the same as those defined for the BR Bit Rate subparameter, as
defined in Table 3.6 in this manual.
