BPX Switch Peripherals

This appendix provide details on BPX switch peripheral equipment, including printers and modems. The appendix includes the following sections:

Network Management

Cisco StrataView Plus Terminal

A Cisco StrataView Plus workstation is recommended for managing a network containing IPX, IGX, and BPX switch. Refer to the Cisco StrataView Plus Operation Manual and Cisco StrataView Plus Installation Manual for setup instructions and specifications for the Cisco StrataView Plus NMS, which is required to provide network alarm, control, and statistics monitoring.

Note For network management, a Cisco StrataView Plus workstation is connected to the LAN port of one or more network nodes, typically BPX switches because of their processing power, to provide network management.

Control Port, Local Control

A terminal (pc or workstation, including a Cisco StrataView Plus workstation) can be connected to the CONTROL port of a BPX switch for temporary or local control. This can be especially useful during installation, initial power-up, and configuration. Refer to Table C-1 for configuration data for the BPX CONTROL port.

Table C-1: Control Port Parameters for Local Control (pc or workstation)

Parameter	Setting
BPX switch Port Used:	Serial CONTROL port, located on a BCC back card, is used to interface to a local terminal.
Code:	Standard 7 or 8-bit ASCII; 1 or 2 stop-bits; even, odd or no par-ity.
Interface:	RS-232 DCE.
Data Rate:	All standard asynchronous data rates from 300 to 19200 bps, independently software-selectable.
Supported Terminals:	Any terminal compatible with DEC VT-100.
Cable Required:	Straight-through RS-232 cable.

Printer

An optional maintenance printer for the BPX switch is the Okidata Model 184 dot matrix printer. This printer may be connected to any node. Refer to Table C-2 and Table C-3 for printer configuration requirements. Note that this is not the same as the printer that may be provided with the Cisco StrataView Plus NMS terminal but in addition to it.

Table C-2: Auxiliary Port Parameters for OkiData 184 Printer

DIP Switch Settings for Okidata 184

DIP Switch A is an 8-section DIP switch located on the printer's main circuit board. Access to the configuration switches is made by sliding back the switch cover at the top, rear of the printer case. Set Switch A as indicated in Table C-3.

Modems, Dial-In and Dial-Out

Customer service uses modems for diagnosing and correcting customer problems with installed BPX switches. The modem that is currently recommended for use with the BPX switch is the Codex Model V.34R.

A dial-in connection to a BPX switch RS-232 from customer service via a modem uses the CONTROL port of the BPX switch. A dial-out connection from a BPX switch via a modem to customer service uses the AUXILIARY port of the BPX switch. Refer to Table C-6 for interface requirements.

Table C-6: Modem Interface Requirements

Parameter	Requirement
BPX switch Port Used:	CONTROL port on BCC back card is used for auto-answer modem setup. AUXILIARY port on a BCC back card is used for auto-dial modem setup.
Code:	Standard 8-bit ASCII, 1 stop-bit, no parity.
Interface:	RS-232 DCE.
Cable to modem:	Null modem cable: CONTROL or AUXILIARY port to modem (DCE to DCE)
Phone Lines:	Dedicated, dial-up business telephone line for Customer Service-to-BPX switch modem.
Data Rate:	All standard asynchronous data rates from 300 to 19200 bps, independently software-selectable.
Supported Modems:	Motorola V.34R 28.8 baud modem with or without talk/data button.

Motorola V.34R BPX Switch Dial-In Configuration

BPX Switch Auto-Answer (Dial-In to BPX switch)

The following is a setup procedure that allows customer service to dial in to the customer's BPX switch to provide support and troubleshooting:

Step 1 Using the cnfterm command, set the BPX 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 RS-232 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 C-7 to set up the modem for proper operation.

Note Consult the manual that is supplied with your modem for specific information concerning the modem configuration. Call customer service for latest modem configuration information.

Step 5 Disconnect the terminal and the straight-through cable from the BPX CONTROL port.

Step 6 Connect the modem to the BPX CONTROL port using a null-modem cables Figure C-1. A null modem cable is used, as the connection is essentially a DCE to DCE rather than a DTE to DCE connection.

Step 7 Ask customer service to assist in testing the operation of the modem setup.

Table C-7: V.34R Modem Configuration for Auto-Answer

Step	Command	Function
1.	AT & F	Reset to factory default.
2	ATL1	Set modem loudness, modem speaker at low volume.
3.	ATSØ=1	Enables Auto-Answer Mode on modem (answer on first ring).
4	AT\N3	Enables automatic MNP error correction.
5	AT%C	Disables data compression.
6.	AT\QØ	Disables XON/XOFF flow control.
7.	AT&S1	Sets DSR to "normal".
8.	ATEØ	Disables local character echo. Modem will not echo what you type.
9.	ATQ1	Disables result codes. (Modem will appear "dead", will stop responding "OK" to commands.)
10.	AT&W	Saves current configuration settings in non-volatile memory. (Writes and stores to configuration location 1.)

IPX Auto-Dial to Customer Service

The following is a setup procedure for the customer's BPX to dial up customer service.

Step 1 Using the cnfterm command, set the BPX AUXILIARY 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 C-8 (V.34R modem without talk/data pushbutton) or Table C-9 (V.34R modem with talk/data pushbutton), to set up the modem for proper operation.

Note Consult the manual that is supplied with your modem for specific information concerning the modem configuration. Call customer service for latest modem configuration information.

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 C-2.

Step 7 Ask customer service to assist in testing the operation of the modem setup.
