• Provide a remedy against echoes.
Change the following bit setting for service data #1 SSSW SW03:
Bit4 -> 1: to cause the machine to ignore the first DIS signal from the other party.
Bit5 -> 1: to cause the machine to transmit a tonal signal (1850/1650 Hz) in response to the
Bit6 -> 1: to cause the machine to send a 1850-Hz tonal signal if bit 5 is set to '1'.
Bit7 -> 1: to cause the machine to send a tonal signal before sending the CED signal.
• EPT (echo protect tone)
Change the setting of service data #1 SSSW SW03 bit 1:
Bit1 -> 1: to cause the machine to send EPT.
• Adjust the NL equalizer.

No. 003: number of lines in connection with bursts; change it so that it is closer to 99 lines.
No. 004: number of errors falling short of a specific number of lines in connection with
bursts; change it so that it is closer to 99.
• Increase the length of silence after reception of CFR.
Set '1' for service data #1 SSSW SW04 bit 4.
Bit4 -> 1: length of time during which a low-speed signal is ignored after transmission of CFR;
-> 0: to cause the machine not to ignore the first DIS signal from the other party.
DIS signal from the other party.
-> 0: to cause the machine not to send a total signal (1850/1650 Hz) in response to the
DIS signal from the other party.
-> 0: to cause the machine to send a 1650-Hz tonal signal if bit 5 is set to '1'.
-> 0: to cause the machine not to send a tonal signal before sending the CED signal.
-> 0: to cause the machine not to send EPT.
