1. Introduction

The PLS-345 Physical Layer Switch is a versatile A/B switching

system, which can be controlled over any TCP/IP network using

standard Telnet, or out-of-band using an external modem and

basic VT100 type terminal emulation. Each of the three A/B

circuits can be switched via code command, or locally via

manual switches on the instrument front panel. Other intelligent

features include password protected access to command mode

functions, site I.D. Message, connector labels, status displays

and more.

The PLS-345 is designed for applications that require automatic

routing of Cat5 10/100Base-T signals between a common jack

and an A and B jack. The PLS is also ideal for switching

RS-232, DSL, RS-422/485, or telephone lines.

Monitor Mode

The Monitor Mode allows the PLS-345 to monitor an external

RS-232 line or contact closure input and automatically switch

selected A/B paths. Easily definable parameters allow the user

to select the monitor signal trigger duration, circuits to switch,

and the option to return circuits to their original A/B position.

Security Features

Address-specific IP security masks prevent unauthorized sources

from accessing the PLS-345 menu through the network. The

PLS-345 provides two levels of operational passwords; the

system administrator level, which allows access to all

configuration and switching functions, and the user level, which

only allows switching of the circuits.

Easy to Configure, Easy to Use

The PLS-345 can be configured over the network, via modem, or

from a local PC or terminal connected to the unit's Console Port.

Easy to use commands let you assign a location name, set system

parameters, and view circuit status. Circuits can be switched

using numbers or names.

3. Access the Command Mode: In order to invoke

commands and display status screens, you must first access

the PLS command mode via Network, modem, or Console

Port (local PC.) For more information, on command mode

access, please refer to Section 5.2.

Notes:

Network Access: The PLS includes a default IP

•

Address and Subnet Mask. This allows initial

contact with the unit via network without first

defining an IP address (providing you are

contacting the PLS from another node on the same

subnet.) When installing the PLS in a working

network environment, it is recommended to define

network parameters as described in Section 5.6.

Modem & Console Port Access: Factory set PLS

•

parameters are as follows: 9600 bps, 8 Data Bits,

One Stop Bit, No Parity. Although PLS parameters

can be easily redefined, for this Quick Start

procedure only, it is recommended that you

configure your communications program to accept

the default parameters.

a) Network Access: Start your Telnet program, then

Telnet to the default PLS IP Address

(192.168.168.168.) For example, on a UNIX system,

the telnet command would be invoked as shown below.

$ telnet 192.168.168.168 [Enter]

After the telnet command is invoked, the PLS Circuit

Status Screen (Figure 3.1) should be displayed,

followed by the PLS> command prompt.

If you wish to contact the PLS from a node that is not

on the same subnet you can either change your PC's IP

address to an address that is on the same subnet as the

PLS (e.g., 192.168.168.xxx), or access the PLS

command mode via modem or Console Port, and define

Network Parameters as described in Section 5.6.

The PLS Network Port is an RJ45, 10Base-T Ethernet Jack, for

connection to a TCP/IP network. Connect your network interface

to the PLS Network Port.

The PLS features a default IP Address (192.168.168.168.)

Providing that you are communicating with the unit from a node

on the same subnet, this allows you to initially contact the PLS

without first accessing the PLS command mode to define an IP

address. Note however, that when installing the PLS in a

working network environment, it is strongly recommended to

assign the IP Address, Gateway Address, and Subnet Mask as

described in Section 5.6.

Note: The PLS features a 10Base-T Interface.

When connecting the PLS to a 100Base-T interface,

note that most router switches will autosense to

determine if the device is 100Base-T or 10Base-T,

and then configure the network interface accordingly.

If your router switch does not autosense, the network

interface port must be manually set to 10Base-T.

4.5. Connecting an External Modem

Use an appropriate DB9 cable to connect your external modem to

the Modem port on the PLS back panel. Use a standard serial

modem cable. For a description of the Modem Port interface,

please refer to Appendix A. Note that the PLS General

Parameters Menu allows you to define a Modem Initialization

string and Modem Disconnect string as described in Section 5.4.

4.6. Connecting a PC to the Console Port

Use an appropriate DB9 cable to connect the PLS Console Port

to a free COM port on your PC or terminal. Use a standard null

modem cable. For a description of the Console Port Interface,

please refer to Appendix A.

5. SetUp and Configuration

5.1. System Mode and User Mode

In order to restrict access to sensitive command functions, the

PLS-345 features two separate operating modes; System Mode

and User Mode.

The System Mode allows access to all configuration menus, A/B

switching functions and status screens, and the User Mode allows

access only to A/B switching functions and the status screens;

when the User Mode is active, you are not allowed to access the

configuration menus or reset the PLS Network Port.

When the System Password has been defined, the PLS-345 will

display a password prompt whenever the unit is contacted via the

Console Port, Modem Port, or Network Port. The password

entered at this prompt determines whether the unit will start-up

in System Mode or User Mode. If the System Password is

entered, the System Mode will be active. If the User Password is

entered, the User Mode will be active. Both the System

Password and User Password are defined via the PLS's General

Parameters menu.

Note: If the System Password is not defined as

described in Section 5.4, the PLS will not display the

password prompt, and will always start-up in System

Mode; allowing all users to access the configuration

menus without entering a password. Therefore, it is

recommended to always define the System Password

in order to restrict access to sensitive command

functions.

5-1

PLS-345 - Physical Layer Switch; User's Guide

5.2. Communicating with the PLS-345

In order to configure the unit or invoke command functions, you

must first connect to the PLS-345 and access the command mode.

1. Start your communications program (e.g. Hyperterminal.)

Make certain that the PLS and your communications

program are set for the same parameters (e.g. COM port,

baud rate, etc.)

2. Access the Command Mode:

a) Local Access (Console Port): To access the command

mode from a local PC connected directly to the PLS

via the Console Port, press [Enter].

i. If you have already hit other keys, press [Enter]

twice. There must be no other characters

preceding [Enter].

ii. If the System Password has been defined, the

password prompt will be displayed. Key in your

System Password or User Password and press

[Enter]. The PLS-345 will display the Status

Screen (Figure 5.1), followed by the "PLS>"

command prompt.

Note: In order to change PLS configuration

parameters, the unit must be operating in System

Mode.

b) Modem Access: To access the command mode via

modem, proceed as follows (Note that an external

modem must be installed at the PLS Modem Port):

i. Dial the number for the external modem connected

to the PLS Modem Port.

ii. If you have already defined the System Password,

a prompt will be displayed. Key in your System

Password or User Password and press [Enter]. If

the System Password has not been defined, then

just press [Enter]. The PLS will display the

Status Screen (Figure 5.1), followed by the "PLS"

command prompt.

c) Network Access: The PLS includes a default IP

address (192.168.168.168), which allows you to

contact the unit from any network node on the same

subnet. When the PLS is installed in a working

network environment, it is recommended that you

redefined the IP Address, Subnet Mask, and Gateway

Address as described in Section 5.6. To contact the

PLS via network, proceed as follows:

i. Telnet to the PLS's IP address. For example, if the

IP address is "192.168.168.168", then on a UNIX

system, the Telnet command would be invoked as

follows:

$ telnet 192.168.168.168 [Enter]

ii. Note that if the Telnet connection is refused, this

may mean that either the IP Security feature (see

Section 5.6.1), has denied the connection, or the

unit is operating on a 100BaseT network that does

not autosense for 10BaseT devices (see

Section 4.4.)

iii. If the System Password has been defined, the

password prompt will be displayed. Key in your

Figure 5.5: The IP Security Menu

5.6.1. Implementing IP Security

The PLS-345 can be configured to restrict unauthorized IP

addresses from Telneting to the unit. This allows the user to

grant Telnet access only to a specific group of IP Addresses, or

block a particular IP address from gaining access. In the default

state, the PLS accepts incoming IP connections from all hosts.

To configure the IP Security feature, proceed as follows:

1. Access the Network Parameters menu as described in

Section 5.6. Note that the Network Parameters Menu and

IP Security Menu are not available in User Mode.

2. When the Network Parameters menu appears, type 4 and

press [Enter] to access the IP Security menu (Figure 5.5).

3. The IP Security menu lists five IP Security "masks" along

with the selected permit/deny action for each mask.

a) Each Security Mask prompt is used to define a specific

IP address or range of IP addresses. Each Mask

Action prompt is used to define the permit/deny action

for the corresponding Mask.

b) Masks are listed in order of ascending priority; Mask 1

has the lowest priority, Mask 5 has the highest priority.

c) Masks have a cumulative effect; high priority masks

supersede the effect of lower priority masks.

d) Each IP Address consists of a series of four eight bit

numbers. The number 255 is used as a wild card.

5-11

PLS-345 - Physical Layer Switch; User's Guide

Example 1: Deny access to all hosts except 192.1.1.5:

Security Mask #1: 255.255.255.255

Security Mask #2: 192.1.1.5

Mask #1 Action: Deny

Mask #2 Action: Permit

Since 255 is a wild card, Mask #1 blocks all IP Addresses. Mask

#2 then specifically grants access to 192.1.1.5 only.

Example 2: Allow access only by addresses that begin with 192.

Security Mask #1: 255.255.255.255

Security Mask #2: 192.255.255.255

Mask #1 Action: Deny

Mask #2 Action: Permit

Since 255 is a wild card, Mask 1 blocks all IP addresses. Mask 2

then grants access to all addresses that begin with 192.

Example 3: Allow access only by addresses that begin with 192,

deny access to 192.1.1.5.

Security Mask #1: 255.255.255.255

Security Mask #2: 192.255.255.255

Security Mask #3: 192.1.1.5

Mask #1 Action: Deny

Mask #2 Action: Permit

Mask #3 Action: Deny

Since 255 is a wild card, Mask 1 blocks all IP addresses. Mask 2

then grants access to all addresses that begin with 192. Finally,

Mask 3 specifically blocks access by 192.1.1.5.

Note:

Mask #5 has priority over the other four masks. If

Mask #5 is set to deny access by

•

"255.255.255.255" (all wild cards), all IP

Addresses will be blocked, and you will not be able

to access the PLS Command Mode via network.

Access will only be allowed via the Console Port

or Modem Port.

When using the wild card address

•

"255.255.255.255" to block access by all IP

Addresses, make certain that at least one higher

priority mask permits access by your IP address.

Section 5: SetUp and Configuration

5.7. The Monitor Mode

The Monitor Mode allows the PLS-345 perform automatic A/B

switching in response to signal changes at the monitor port on

the instrument back panel. The Monitor Mode can be set to

monitor a Contact or an RS-232 Line.

5.7.1. Hardware Configuration

In order to employ the Monitor Mode, you must first connect the

monitored line to the PLS unit, and configure the Monitor

Selector Switch as follows:

1. Determine whether you will be monitoring a contact or an

RS232 line. Locate the Monitor Selector Switch on the

PLS back panel, and set the switch in the appropriate

position.

2. Connect the line that you wish to monitor to the Monitor

Input Connector on the PLS back panel.

a) RS232: Connect the appropriate RS232 pin to the

Monitor Input Connector.

b) Contact: Connect a line from the contact that you

wish to monitor to the Monitor Input Connector.

c) Ground Line: Connect an appropriate ground line to

the Ground Connector on the PLS back panel.

5.7.2. Selecting Monitor Mode Parameters

After the monitored line is connected to the PLS, you must then

use the Monitor Mode Parameters Menu to configure the Monitor

Mode and determine which A/B circuits will be switched.

From the PLS> command prompt, type /M and press [Enter].

The Monitor Mode Parameters Menu will be displayed

(Figure 5.6). Note that the Monitor Mode Parameters Menu is

not available in User Mode. The Monitor Mode Parameters

Menu offers the following options:

Note: Do not enable the Monitor Mode (Item 1)

until you have finished selecting the other Monitor

Mode parameters. This will prevent the A/B

circuit(s) from being accidentally switched when

Monitor Mode parameters are changed.

1. Monitor Mode: Enables/disables the Monitor Mode

feature. Do not enable the Monitor Mode until you have

finished selecting the other Monitor Mode parameters.

(Default = Off.)

2. Switch If Level: Determines which line condition will

cause the selected A/B circuits to switch. This item can

either be set to "0 - Low" or "1 - High". When this item is

set at "0 - Low", the selected A/B circuit(s) will be

switched when the line goes low. When this item is set at

"1 - High", the selected A/B circuit(s) will be switched

when the line goes high. (Default = "0 - Low".)

3. Switch to Position: Determines which A/B line will be

automatically selected when the line goes to the target

level (Item 2.) For example, if Item 2 is set at "0 - Low"

and Item 3 is set at "B", then the monitored line goes low,

the selected A/B circuit(s) will be switched to Line B.

(Default = B.)

4. Delay Period: Determines how long the monitored line

must remain at the target level (Item 2) in order to trigger

automatic A/B switching. For example, if the target level

is "1 - High" and the Delay Period is 1 minute, then the

selected A/B circuits will be switched when the monitored

line remains high for 1 minute. (Default = 5 Seconds.)

Note: When Item 5 (Return) is enabled, the Delay

Period also determines how long the line must return

to (and remain at) the normal state in order for the

A/B line to be switched back to it's original setting.

5-14

Section 5: SetUp and Configuration

5. Return: When enabled, the Monitor Mode will return the

switched A/B circuit(s) to the original A/B position if the

monitored signal also returns to its normal state.

(Default = Off.)

For example, assume the Monitor Mode is configured as

follows:

Switch if Level: 1 - High

Switch to Position: B

Return: On

If the circuit starts in position "A", and the monitored line

goes high, then the circuit will be switched to the "B"

position. However, since the Return feature is enabled, if

the line later returns to the "low" state, the circuit will also

be switched back to the "A" state.

Note: When Item 5 (Return) is enabled, the Delay

Period also determines how long the line must return

to (and remain at) the normal state in order for the

A/B line to be switched back to it's original setting.

6. Circuits to Switch: Determines which of the PLS's three

switched A/B circuits will be controlled by the Monitor

Mode. Note that when this item is used to enable the

Monitor Mode at a given A/B circuit, then the Circuit

Status Screen will display an asterisk in the "MON"

column for that circuit. To choose the circuits that will be

controlled by the Monitor Mode, proceed as follows:

a) From the Monitor Mode Parameters Menu, type 6 and

press [Enter]; the PLS will display a menu that lists

all three available A/B Circuits.

b) Key in the number for the desired circuit, and press

[Enter]; the PLS will display another menu which

allows you to include or exclude the circuit from the

Monitor Mode.

c) To assign the circuit to Monitor Mode, select "On", to

remove the circuit from Monitor Mode, select "Off".

After you have finished selecting parameters for the Monitor

Mode, make certain to return to Item 1 in the Monitor Mode

Parameters Menu and enable the Monitor Mode feature. The

Monitor Mode will not function unless it has been enabled.

7. Operation

The PLS-345 offers three different methods for switching

A/B paths:

1. Manual A/B Switching: The manual A/B Switches on the

PLS front panel are used to initiate switching of one or

more A/B Circuits.

2. Code Activated A/B Switching: ASCII commands are

sent to the PLS to initiate switching of one or more

A/B Circuits.

3. Automated A/B Switching (Monitor Mode): The PLS

monitors a signal received via the Monitor Input Port, and

switches one or more A/B Circuits according to

user-defined parameters.

These methods are discussed in the sections that follow.

7.1. Manual A/B Switching

The most basic method for switching A/B paths is accomplished

using the manual A/B switches on the PLS front panel. When

performing Manual A/B switching, note the following:

· The Master A/B Switch (Labeled "All") can be used to

switch all three A/B Circuits.

· When an A/B Circuit is switched, the corresponding LED

indicators on the instrument front panel and back panel will

light.

7-1

PLS-345 - Physical Layer Switch; User's Guide

7.2. Code Activated A/B Switching

The PLS offers three different commands for controlling A/B

switching:

· The /A command, which is used to switch one or more

circuits to the "A" line.

· The /B command, which is used to switch one or more

circuits to the "B" line.

· The /D command, which is used to switch all three circuits

to their user-defined default A/B positions.

All three of these commands are available in both System Mode

and User Mode.

7.2.1. The /A Command and the /B Command

The /A command and the /B command can be used to control the

"A" or "B" position of one or more of the A/B circuits. The /A

command will switch one or more circuits to the "A" line, and

the /B command will switch one or more circuits to the "B" line.

Both the /A command and the /B command use the following

format:

/A <n> [Enter] or /B <n> [Enter]

Where, n is one of the following:

· Switch One Circuit: To switch one A/B circuit, enter the

number or common name of the desired circuit. For

example, to switch circuit 2 to the "A" position, type

/A 2 [Enter].

· Switch Two Circuits: To switch two circuits to the same

A/B position, enter the numbers or common names of the

desired circuits with a "plus" sign (+) between them (e.g.

n+N). For example to switch circuits 1 and 3 to the "B"

position, type /B 1+3 [Enter].

· Switch All Circuits: To switch all three A/B circuits to the

same A/B position, enter an asterisk (*) in place of the

circuit number or name. For example, to switch all three

circuits to the "A" position, type /A * [Enter].

7-2

Section 7: Operation

The Command Confirmation Prompt:

Normally, when the /A or /B commands are invoked, the PLS

will prompt you for confirmation before actually implementing

the command. If you wish to suppress this confirmation prompt,

and execute commands without confirmation, you can employ

one of the following methods:

· Include the ",y" option in the command line (e.g. /A 1,y.)

· Disable Command Confirmation as described in Section 5.4.

· Enable the Automated Mode as described in Section 5.4.

7.2.2. The /D Command

The /D command can be used to switch all three PLS-345 circuits

to their user-defined default A/B positions. Default A/B

positions are defined via the Circuit Parameters Menus (/P n.)

When the /D command is invoked, the PLS will set all three

circuits to their default A/B positions, and then display the status

screen, followed by the PLS> command prompt.

The Command Confirmation Prompt:

Normally, when the /D command is invoked, the PLS will prompt

you for confirmation before actually implementing the command.

If you wish to suppress this confirmation prompt, and execute

commands without confirmation, you can employ one of the

following methods:

· Include the ",y" option in the command line (e.g. /D,y.)

· Disable Command Confirmation as described in Section 5.4.

· Enable the Automated Mode as described in Section 5.4.

7-3

PLS-345 - Physical Layer Switch; User's Guide

7.3. The Monitor Mode

The Monitor Mode allows the PLS-345 perform automatic A/B

switching in response to signal level changes at the monitor port

on the instrument back panel. The Monitor Mode can be set to

monitor a Contact or an RS-232 Line. For more information on

the Monitor Mode, please refer to Section 5.7.

7-4

8. Saving and Restoring

Configuration Parameters

After the PLS has been properly configured, parameters can be

downloaded and saved as an ASCII text file. Later, if the

configuration is accidentally altered, the file with the saved

parameters can be uploaded to automatically reconfigure the unit

without the need to manually assign each parameter.

Saved parameters can also be uploaded to other PLS units. This

allows rapid set-up when several units will be configured with

the same parameters.

The “Save Parameters” procedure can be performed from any

terminal emulation program (e.g. HyperTerminal, ProComm,

etc.), that allows downloading of ASCII files.

8.1. Sending Parameters to a File

1. Start your terminal emulation program (e.g.

HyperTerminal) and access the PLS Command Mode. If

the password prompt is displayed, enter the System

Password.

2. When the PLS> command prompt appears, type /DL and

press [Enter]. The PLS will prompt you to configure your

terminal emulation program to receive an ASCII download.

a) Set your terminal emulation program to receive an

ASCII format download, and the specify a name for a

file that will receive the saved parameters (e.g.

PLS.PAR).

b) Disable the Line Wrap function for your terminal

emulation program. This will prevent command lines

from being broken in two during transmission.

3. When the terminal emulation program is ready to receive

the file, return to the PLS Save Parameter File menu, and

press [Enter] to proceed with the download. PLS

parameters will be saved on your hard drive in the file

specified in Step 2 above.

8-1

PLS-345 - Physical Layer Switch; User's Guide

4. The PLS will send a series of ASCII command lines which

specify the currently selected PLS parameters. The last

line of the file should end with a “/G-00” command.

When the download is complete, press [Enter] to return to

the "PLS>" command prompt.

8.2. Restoring Saved Parameters

This section describes the procedure for using your terminal

emulation program to send stored parameters to the PLS.

1. Start your terminal emulation program and access the PLS

Command Mode; if the password prompt is displayed, enter

the System Password.

2. Configure your terminal emulation program to upload an

ASCII text file.

3. Upload the ASCII text file with the saved PLS parameters.

If necessary, key in the file name and directory path.

4. Your terminal emulation program will send the ASCII text

file to the PLS. When the terminal program is finished

with the upload, make certain to terminate the Upload

mode.

Notes:

If the PLS detects an error in the parameters file, it

•

will respond with the “Invalid Parameter” message.

If an error message is received, carefully check the

contents of the parameters file, correct the

problem, and then repeat the Upload procedure.

When the configuration file is sent to the PLS via

•

Telnet, the IP Address, Subnet Mask, and Gateway

Address will not be changed until all Telnet

connections to the unit are terminated (including

the connection that was used to send the saved

parameters file.)

5. If the parameter upload procedure is successful, the PLS

will send a confirmation message, and then return to the

"PLS>" command prompt. Type /S and press [Enter], the

PLS Status Screen will be displayed. Check the Status

Screen to make certain the unit has been configured with

the saved parameters.
