Environment
- Synchronous (Hayes) external modem
- I/NET Dial Applications
Cause

Resolution
See TCON101, TCON213, TCON226 and TCON298 for more details
- PC, modem, and phone line must be connected and “ON”.
- To program a modem, the modem must be direct connected to the PC
- Connect the modem to an analog phone line only.
- Remember the host needs a 78041 or a 78051 tap (not Embedded 4x)
- Warning! Using a non-analog line will damage the modem!
- Make sure the correct modem driver is installed.
- Add the modem hardware in Windows Control Panel
- In the “Phone And Modem Options” editor, go to the “Modems” tab
- Remove any profiles of modems that are not currently connected to the INET comm port.
- If you are running Windows 2000, the “Microsoft H.323 TAPI Service Provider” should be the telephony provider highlighted under the “Advanced” tab, in the Phone And Modem Options Editor of Windows 2K Control Panel.
- From the “Modems” tab, go to Properties / Diagnostics / and Query Modem. Go to Modems / Properties / General, and set the Maximum Port Speed at 9600.
- Close Windows Control Panel
- View the modem’s Active and Stored settings:
- Type “ATE1” to place echo to “On” mode
- “AT&V” followed by the “Enter” key displays the settings the modem is using and the NOVRAM settings in profile “&Y0” and &Y1
- If the settings need to be changed then continue
- Recommend “AT&F” to reset the modem to factory defaults.
- The Host and Site modems use the same settings.
- Both modems should be as follows:
Active Profile: B1 B16 B30 B41 B52 B60 B70 B75 B80 E1 L2 M1 N0 P Q0 V0 W0 X4 Y0 &A0 &B1 &C1 &D3 &G0 &K3 &L0 &Q1 &R0 &S1 &T4 &U0 &X0 &Y0 S00:001 S02:043 S03:013 S04:010 S05:008 S06:002 S07:060 S08:002 S09:006 S10:014 S11:095 S12:050 S25:005 S26:001 S36:001 S37:009 S38:020 S46:002 S48:007
- Suggest you store the settings in both profiles of the modem’s NOVRAM.
- “&W0” stores to “&Y0”
- “&W1” stores to “&Y1”
- TAPs : EPROM(s) and BIN files need to be synchronous and INET rev compatible
- After following the preceding steps for the remote site’s modem:
- Connect the modem to the Tap (or emulated Tap) and Analog Phone Line
- Power-up the modem
- Press the controller’s reset button or cycle the Tap’s power
- Do NOT cycle the modem’s power
- The “RD” and “SD” should flash after several seconds have past
- After about 30 seconds the “MR”, “AA”, and “TR” lights should be “On”
- Using I/NET, Dial the site. Make sure the host can:
- Dial out (you can here the dial tone)
- Handshake with the remote Modem
- Maintain its connection to the remote modem (Neither modem inadvertently terminates call)
- See the Controller(s) on the LAN
- Actually connect to the controller(s)
- View points in the summary screens
Warning! Using a non-analog line will damage the modem!
