Modems

In general, a dial-out connection to a modem uses the AUX port of the IGX. A dial-in connection from a modem uses the CONTROL port of the IGX. Refer to Table B-6 for interface requirements.


Table B-6: Modem Interface Requirements
Parameter Requirement

IGX Port Used:

CONTROL port on SCM card is used for auto-answer modem.
AUX PORT on SCM card is used for auto-dial modem.

Code:

Standard 8-bit ASCII, 1 stop-bit, no parity.

Interface:

RS-232 DCE.

Cable:

Null modem cable.

Phone Lines:

Dedicated, dial-up business telephone line for ISC-to-IGX modem and auto-dial-to-ISC modem.

Data Rate:

All standard asynchronous data rates from 300 to 19200 bps, independently software-selectable.

Supported Modems:

Motorola Model V.34R 9600 baud modem.

Motorola V.34R IGX Dial-In/Out Configuration

IGX Auto-Answer

This is a setup in which the ISC can dial into the customer's IGX. Using the cnfterm command, set the IGX CONTROL port speed to 9600 bps. Using the cnftermfunc command, set the terminal type to VT100/StrataView. To program the modem, temporarily attach a terminal to the modem using a null modem cable. The modem EIA port will automatically match the 9600 bps setting of the terminal. Enter the commands listed in Table B-7 to set up the modem for proper operation.


Table B-7: Setting Up the Motorola V.34R Modem for Auto-Answer mode
Step Command Function

1.

AT&F&W

Reset to factory default and save.

2.

ATSØ=1

Enables Auto-Answer Mode (answer on first ring).

3.

ATL1

Modem speaker at low volume.

4.

AT*SM3

Enables automatic MNP error correction.

5

AT*DC0

Disables data compression.

6.

AT*FL0

Disables XON/XOFF flow control.

7.

AT&S1

Sets DSR to "normal".

8.

ATEØ

Disables local character echo.

9.

ATQ1

Disables result codes. (Modem will appear "dead.)

10.

AT&W

Saves current configuration settings in non-volatile memory.

IGX Auto-Dial to ISC

Using the cnfterm command, set the IGX Auxiliary port (AUX PORT) speed to 9600 bps and enable XON/XOFF flow control. Using the cnftermfunc command, select option 7, "Autodial Modem", enter the ISC-designated Network ID, and the ISC modem phone number. Attach a 9600 bps terminal to the modem using a cross-over cable and enter the following commands (Table B-8).

Connect the modem to the IGX AUX PORT using the cable shown in Figure B-1. Ask StrataCom ISC to assist in testing the operation of the modem setup.

Modem Cables

The IGX Auto-Dial to ISC application (also called "phone home") and IGX Auto-Answer (call from StrataCom ISC) application use different modem cables. Figure B-1 shows the modem cable pinout for IGX Auto-Dial to ISC. Figure B-2 shows the modem cable pinout for IGX Auto-Answer (call from ISC).
