set my COM speed in Windows to 230.4 Kbps (230,400), my TA won't dial
out.
Using the 230.4 Kbps COM port speed with Windows requires a special serial
port. Most new computer's serial ports operate at up to
115.2 Kbps. To use your TA at 230.4 Kbps, check with your computer
manufacturer to see if your serial port will support that speed.

Q: What is call forwarding and how do I do it?
The call forwarding means the switch will ring another number at a place
where you will be when someone dials your directory number.
You pick up the handset and dial the access code assign by your telephone
company and the number that you want the calls forwarded. Check with your
telephone company for this access code.
Q: How do I suspend/resume a phone call (Terminal Portability)?
The Terminal Portability service allows you to suspend a phone call
temporarily. You can then resume this call later, at another location if you wish.
To suspend an active phone call:
press Flash button then dial *79#.
To resume your phone call:
step1: Reconnect at a telephone (ISDN) that is linked to the same S/T
interface(Network Terminator-1, NT1) where you suspended the call.
step2: Pick up the handset and dial *79#.
Q: Why does the phone ring while I hang it up? (Reminder Ring)
TA reminds you there is one call on hold except the current active call (the
hang up one).
Q: What are CLIP and CLIR?
CLIP or CLIR refers to CLID Presented or Restricted.
TA can set the CLIP/CLIR bit in SETUP message to request the Switch,

message to the called party.

Be sure your analog phone line and ISDN line are installed correctly.
The green LED "LNK" should light on steadily and LED "PHONE" should flash
Omni.Net Lite Support Notes
while you Hook-off.
Q: The supplementary services can't work on my analog ports.
These supplementary services need to be activated by the phone company.
You need to subscribe the desired supplementary services on your line. Check
if your local ISDN Exchange phone company does support these services.
Q: Why does my TA light up only 64K (one B channel) while I need 128K
both B1 and B2) for my Internet connection?
The default data connection type is Dynamic 128K MLP, TA will keep
one B channel or two B channel depends on traffic load.
You may run the Configuration Utility to setup the add/drop threshold
for the second B channel.
Or run Configuration Utility to set the data connection type
to Fixed 128K will make TA stay on 128K connection.
Q: My TA data port stays on 128K (two B channels) when there is an
incoming voice call, it should release one B channel for the voice call.
You need to subscribe the call waiting service for the Call Bumping feature
(Bandwidth release for incoming voice call) to work.
Q: My Internet Charging is excessive that I have dialed.
Make sure the MLP(128KBps) call can be accepted by your ISP before you
activate the MLP mode. TA will try to establish the second B channel in MLP
call while necessary.
If your ISP doesn't allow the second B channel, the phone company
will bill you for attempting multiple connection.
Q: I do not have a satisfactory data rate transfer for my 64kbps/128kbps
connection.
Check if your RS232 COM port speed is set to 115200bps or above.
Omni.Net Lite Support Notes
Some enhanced RS232 COM port could support 230400bps to fully utilize the
128kbps bandwidth.
Most PC support 115200bps only, you may have the most around 7KB to 8KB
(Bytes per second) data rate for the 64kbps call; for 128kbps call, the
achievable rate is around 90kbps theoretically(115200*0.8 for 8 data bits plus 1
start bit and 1 stop bit).
Try not to connect the internet at busy hours. Your ISP could fail to provide
greater rates of data transfer.
Q: I can't connected to the Internet using my old analog modem account.
You need to apply an new ISDN connection account for 64kbps or
128kbps data rate. Usually the account for analog modem dial up
is different than ISDN dial up.
Q: When I try to place a call to my ISP, I am unable to make a connection.
Make sure you have applied ISDN dial up account and your TA is properly
configured. Using Utility to setup the correct "Call Type" as "PPP or MLP". This
is the most common connection protocol used by ISP. Verify that the B1 or B2
light on the front of your TA illuminates when you place a call to ISP. Insure you
do dial out the call.
Uncheck the Encrypted Password Option in your Windows Dial-Up Networking
to adopt PAP to make the successful call first.
