(1% to 99%).

7. Echo Remedy
An echo remedy is provided on the part of either the transmitting machine or the receiving
machine.
Echo Remedy 1 (by the transmitting machine; for long distance):
By the User:
Set the long distance mode as part of registering for auto-dialing (one-touch dialing, coded
speed dialing):
• If set to 'long distance 1', the machine will ignore the 1st DIS transmitted by the other party.
• If set to 'long distance 2', the machine will transmit a 1850-Hz tonal signal in response to DIS
from the other party.
• If set to 'long distance 3', the machine will transmit a 1650-Hz tonal signal in response to DIS
from the other party.
By the Service Man:
Changing SW03 bit 6, bit 5, and bit 4 of service soft switch #1 SSSW will affect all settings,
i.e., all transmissions will be long distance transmissions:
long distance 1:
long distance 2:
long distance 3:
Echo Remedy 2 (by the receiving machine; adds a 1080-Hz total signal before
transmission of CED):
Set SW03 bit 7 of service soft switch #1 SSSW to '1' so that a 1080-Hz total signal is transmit-
ted before transmission of CED.
Echo Remedy 3 (by the receiving machine; changes the period in which the low speed
signal is ignored after transmission of CFR):
Set SW04 bit 4 of service soft switch #1 SSSW to '1' so that the period in which the low speed
signal is ignored after transmission of CFR is changed from 700 to 1500 msec.
8. Echo Protect Tone: SW03 bit 1 of Service Soft Switch #1 SSSW
Add an echo protect tone to the V.29 modem signal for transmission:
When SW03 bit 1 is set to '1', an echo protect tone will be added to high-speed transmission
V.29 (at 9600 or 7200 bps) for transmission.
bit 6, bit 5, bit 4 = 0, 0, 1
bit 6, bit 5, bit 4 = 0, 1, 0
bit 6, bit 5, bit 4 = 1, 1, 0
