Having problems getting our new laptops with external USB modems to connect with our Octel 200's. Old laptops with internal modems worked fine connecting to these same Octels.
I can dial into the Octel and get the nice login screen. As I type the 2nd or 3rd letter of my password, the connection drops.


Currently using ProcommPlus 4.8, settings are:
terminal VT100
protocol Xmodem
9600 baud
Standard EC data protocol
compression enabled
no flow control
7-E-1, Standard modulation.

I thought about forgetting ProComm and trying to use ASA 6.0 instead but I can't that to work either. I don't even know if that is possible.

Any ideas would be appreciated. I'm ready to throw new laptop out front window. Thank you, Kimberly
 
Your modem must support Bell mode. Use 7 bit /even / 1 stopbit.
9600 baud.

I can't tell if my modem supports Bell mode and the doc is pretty useless.

I did see one for sale that supports bell 212A and Bell 103. Would that do it?

Are there any settings or commands I needed to add? If I just get one that supports Bell mode, would that do it? No settings to change?

Is it possible to access Octel's using ASA?

Thank you, Kimberly
 
Bell mode is a must, I found out many years ago.
I am not sure what "Bell mode type" is required: Bell 212A or Bell 103.

I always use ADM5 when connecting to the Serenade Octel 200/300.
 
I got a modem with Bell mode but that didn't work either. I logged with Avaya but they said they can't help--call IT.
I would think this would be a known issue since my whole group is in the same boat. Newer laptops which no longer come with internal modems don't like connecting with Octel 200's or 250's. I can use the same laptop and USB modem fine with PBX's and even Audix voicemails. Is there something special about Octel 200 or 250? Any ideas? Kimberly
 
I use old LASAT or nokia modem for this purpose, and with a real "COM" port, no USB.

The internal modem is compatible with the following standards: Bell 103/212A and CCITT
V.22/CCITT V.22 bis

If you still have the old laptop you need to check the init string in it and dup it to the new one and that may work.

2. Power cycle the modem.

3. Connect the modem to a PC with ProComm direct onnection set to 9600 7,E,1

4. Enter ATQ <rtn>

5. Verify modem responds with OK.

6. If the modem does not return OK, verify communication setup.

7. Enter ATZ4 <rtn>

8. Enter ATY1 <rtn> (you should see your input echo, but the modem will not respond).

9. Enter ATI4 <rtn>

10. Verify the modem settings - Y1,BAUD=9600,PARITY=E,WORDLEN=7,&B1,&H1,&R2,S00=001

11. If settings do not match, repeat steps (1-10).

12. Enter AT&W1 <rtn>

13. Powercycle the modem.
