Chapter 14 No. Item 024 pseudo RBT transmission level at time of fax/tel switchover 025 Answering machine connection function signal detection time 027 preamble detection time length for V21 low-speed flag Range of settings 10 to 20 0 to 20 (120/230V) 0 to 999 20 (x 10ms) 14.5.2 0011-4148 Use it to set RTN signal transmission conditions. Raise these parameters for more lenient conditions if errors occur frequently at time of reception because of transmission of the RTN signal. Memo: Any of the following error codes may be indicated at time of reception because of RTN signal transmission ##0104, ##0107, ##0114, ##0201 RTN signal transmission condition (1) affects the ratio of error lines to the total number of lines per single page of received images. RTN signal transmission condition (2) affects the standard value (*2) of burst errors (*1). RTN signal condition (3) affects the number of errors not reaching the standard value of burst errors. *1: transmission error occurring cover several lines. *2: for instance, if '15' is set, a single burst error will represent an error occurring continuously cover 15 lines. If any of these lines is detected while an image signal is being received, the RTN signal will be transmitted after receiving the protocol signal of the transmitting party. Higher parameters restrict the transmission of the RTN signal. 14.5.3 0011-4149 Use it to set the length of the pause automatically entered between access code and ID code when the NCC (New Common Carrier) line is used for dialing. 14.5.4 0011-4150 Use it to set the length of the pause automatically entered between ID code and telephone number of the other party when the NCC (New Common Carrier) line is used for dialing. 14.5.5 0011-4151 Use it to set the time for identifying the line connection. Raise this parameter if errors occur frequently at time of communication because of the condition of the line. Memo: Any of the following error codes may be indicated because of the condition of the line ##0005, ##0018 The line condition identification time is between when the dial signal is transmitted and when the line condition is cut for the transmitting party, while it is between when the DIS signal is transmitted and when the line is cut for the receiving party. 14.5.6 0011-4152 Set the T1 timer for the receiver (wait time after DIS transmission starts until a significant signal is received). 14.5.7 0011-4153 Set it so that the 1-line transmission time is longer for reception to prevent reception errors caused by a long data length per line (e.g., computer FAX). 14.5.8 0011-4154 Allows setting of the hooking detection time. 14.5.9 0011-4155 Allows setting of the time from seizing the line till pseudo RBT is sent, when the Fax/ Tel switching function is operating. 14.5.10 0011-4156 Use it to set the pattern of the pseudo RBT signal transmitted at time of a fax/tel switchover. 14.5.11 0011-4157 Use it to set the pseudo CI signal pattern transmitted at time of a fax/tel switchover. 14.5.12 0011-4158 Use it to set the CNG detention level for a fax/tel switchover. 14.5.13 0011-4159 Use it to set the pseudo transmission level for a fax/tel switchover. 14.5.14 0011-4160 Sets the signal detection time for the answering machine connection function operation. When the answering machine connection function is operating, if the function does not operate normally because the fax does not detect CNG signal sent from the line, raise this parameter to increase the signal detection time. 14.5.15 0011-4161 Use it to detect the time of detection after which command analysis is started after detecting V.21 low-speed command preambles continuously for a specific period of time. 14-13
