Slow transmission speed or
intermittent operation

Troubleshooting VADB

If you notice that the terminal's transmission speed is slow or that
operation is intermittent, make sure the transmit and receive cable
connectors are finger tight. (See the Caution statement and note
concerning cable connector tightness following Figure 45 on
page 56.)
If you suspect the HN7700S is not working properly in VADB
mode, follow these steps:
1. Verify at least one of the light-emitting diodes (LEDs) on the
front of the HN7700S is illuminated.
If none of the LEDs are illuminated:
a. Verify the DC power cord is securely connected to the
remote terminal.
b. Verify the power cord is securely connected to the power
source.
c. If the power cord is connected to a surge protector, verify
the surge protector is connected to a wall outlet and turned
on.
2. Verify the phone cable is securely attached to the TEL LINE
port on the HN7700S and the wall telephone jack.
3. Connect an analog telephone to the wall telephone jack. Dial
the VADB access number used by the HN7700S. If you hear
modem tones (high-pitched noises), the telephone line and
VADB access number are working properly.
Note: You may need to contact your network administrator
or Helpdesk to obtain your VADB access number.
4. Verify that the phone cable is not defective by swapping it
with another cable.
5. Contact your Help desk if completing steps 1 through 4 does
not resolve the issue.
Note: It is normal for the TCP Acceleration status to be shown as
disabled when in VADB mode.
