When connecting Superhighway 56 External Modems to Meridian systems the following commands should be entered to ensure correct operation.
· Connect PC to modem with appropriate setting. Eg 9600 baud, 8,1,none
· Enter the following AT string
AT&F (Resets Modem to factory default)
AT&D0&K0&R1&S0&Y0 (&Y0 Ensures profile 0 is used on power up)
ATB0E0L2M1Q1V1X3Y0 (no output from modem)
AT S0=1 (Auto answer after 1 ring)
AT&W (Save settings)
· Connect modem and test.
· To view settings enter AT&V (It should look something like below)

Cables to connect to Meridian
· Option 11 Always connect remote access modem to port 0 where possible as certain functions can only be performed over this port. The 3 way - cable supplied with the option 11 is wired for modem connection so can connect straight in to the modem.
· Opt 51 to 81 There are various types of SDI card that you may come across but the ports should be wired out to a standard 25-way connector on the rear I/O panel. To extend this to a modem or terminal Nortel cable NT8D95 (various lengths) can be used or any standard 25 way cable. The SDI port needs to be strapped for DTE / DCE as required (see NTP’s for settings), or a Null Modem adapter may be required.
The exception to this is if an SDI paddle board is used. These are wired out to the I/O panel but are presented as none standard 9-way connections. Nortel cable NT8D93 is required to connect to a terminal or modem. Again the DTE / DCE needs setting as appropriate.
If a baud rate other than 9600 is required, ie1200 Bd try the following:
AT+MS=1,0,1200,1200
