Fax Protocol Report
The Protocol Report provides transmission results, timing, and communications activity infor-
mation about each Fax transmission. Accessed from the System -> Information -> Trouble-
shooting -> FAX Problems menu, the Protocol Report provides Job Details similar to the
Transmission Report, and a detailed log of the communications activity between devices. Use
this report to diagnose possible communications errors between machines.
Table 1 lists the most common commands exchanged between Fax machines during a typical
transfer of data. When reviewing the Protocol Report, trace the exchange of commands to
identify irregularities. Commands in parentheses (_) may or may not appear in the log.

(NSF) (CSI) DIS Negotiating capabilities from a manual
receiver or an auto answer terminal
(NSC) (CIG) DTC Mode setting from calling terminal

(TSI) DCS Mode setting from manual transmitter
(TSI) (NSS) or automatic receiver.
(PWD) (SUB) (TSI) DCS
CTC Mode setting from the transmitter to
the receiver.
(EOR-NULL) Indicates the next block transmission
from the transmitter to the receiver.

The Transmission Report provides transmission status and activity information about each Fax

transmission. Generation of this report is optional and is in an Error Only state by default. Use
(TSI) DCS
the menus: System -> Job Defaults Setup -> Fax Defaults Setup -> Fax Send Setup to change
(NSF) (CSI) DIS
the Error Only default. Also by default, for the 8860MFP, the Transmission Report includes a
(CRP) (TSI) (NSS)
reduced image of the document scanned for faxing. Result codes appear in the Results box of
CFR
the Job Details section at the bottom of the page. The results format is <code><speed>. Where
FTT
code is one of the codes listed in
(NSC) (CIG) DTC
ically, the results are CP<speed> for a completed Fax. Fax failures (FA) may omit the speed if
(NSF) (CSI) DIS
the system was unable to start the connection. The job termination results (FA, TU, TS) count
(CRP)
as errors for the purpose of printing a Transmission Report.
