This appendix provides details on the IPX peripheral equipment, including printers and modems. The appendix includes the following sections:
A StrataView Plus workstation is required for managing a network containing IPX, IGX, and BPX nodes and associated equipment. Refer to the StrataView Plus Operations Guide and StrataView Plus Installation document for setup instructions and specifications for the StrataView Plus NMS which is required to provide network alarm, control, and statistics monitoring.
A terminal (pc or workstation, including a StrataView Plus workstation) can be connected to the CONTROL port of an IPX for temporary or local control. This can be especially useful during installtion, initial power-up, and configuration. Refer to Table B-1 for configuration data on the IPX CONTROL port. .

| Supported Terminals: | VT-100, or equivalent, recommended. |
| Cable Required: | Straight-through RS-232 cable. |
The maintenance printer that is currently shipped with the IPX is the Okidata Model 184. This printer may be connected to any node. Refer to Table B-2 and Table B-3 for interface requirements.

| 2 | On | |
| 3 | On | |
| 4 | On | DSR active. |
| 5 | On | Buffer = 32 bytes. |
| 6 | On | Timing = 200 ms. |
| 7 | On | Space after power on. |
| 8 | Don't care | Not used. |
Customer service uses modems for diagnosing and correcting customer problems with installed IPX systems. The modem that is currently recommended for use withthe IPX is the Codex model V.34R.
A dial-in connection to an IPX from customer service via a modem uses the CONTROL port of the IPX.A dial-out connection from an IPX via a modem to customer service uses the AUX port of the IPX. Refer to Table B-6 for interface requirements.
| Parameter | Requirement |
|---|---|
| IPX Port Used: | CONTROL port on SCC card is used for auto-answer modem. AUX PORT on SCC 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: CONTROL or AUX port to modem (DCE to DCE) |
| Phone Lines: | Dedicated, dial-up business telephone line for Customer Service-to-IPX modem and auto-dial-to-Customer Service modem. |
| Data Rate: | All standard asynchronous data rates from 300 to 19200 bps, independently software-selectable. |
| Supported Modems: | Motorola V.34R 28.8 modem. |
The following is a setup procedure that allows customer service to dial in to the customer's IPX to provide support and troubleshooting:
Step 1 Using the cnfterm command, set the IPX CONTROL port speed to 9600 bps.
Step 2 Using the cnftermfunc command, set the terminal type to VT100/StrataView.
Step 3 To program the modem, temporarily attach a terminal to the modem using a straight-through cable (DTE to DCE). The modem EIA port will automatically match the 9600 bps setting of the terminal.
Step 4 Enter the commands listed in Table B-7 to set up the modem for proper operation.
Step 5 Disconnect the terminal and the straight-through cable from the IPX CONTROL port.
Step 6 Connect the modem to the IPX CONTROL port using a null modem cable Figure B-1. A null modem cable is used, as the connection is essentially a DCE to DCE rather than a DTE to DCE.
Step 7 Ask Customer Service to assist in testing the operation of the modem setup.
| 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. |
The following is a setup procedure for the customer's IPX to dial up customer service.
Step 1 Using the cnfterm command, set the IPX Auxiliary port (AUX PORT) speed to 9600 bps and enable XON/XOFF flow control.
Step 2 Using the cnftermfunc command, select option 7, "Autodial Modem" and enter the customer service-designated Network ID, and the customer service modem phone number.
Step 3 Attach a 9600 bps terminal to the modem using a straight-through cable. The modem EIA port will automatically match the 9600 bps setting of the terminal.
Step 4 Enter the commands listed in either Table B-8 (V.34R modem without talk/data pushbutton) or Table B-9 (V.34R modem with talk/data pushbutton), to set up the modem for proper operation.
Step 5 Disconnect the terminal and the straight-through cable from the IPX CONTROL port.
Step 6 Connect the modem to the IPX AUX port using a null modem cable Figure B-2.
Step 7 Ask customer service to assist in testing the operation of the modem setup.
