• TCP port 4514 (default: data logging or Syslog server)

62 Cyclades™ ACS 6000 Advanced Console Server

Appendix D: Accessing a Console Server with a DSView 3

Software Installation via Dial-up

When a DSView 3 software user establishes a serial session, the following events occur:

• The user selects a serial port to access.

• A viewer is downloaded from the DSView 3 server to the user's workstation.

• The DSView 3 software passes information to the viewer, such as an authorization key, the console server's IP address and serial port.

• The viewer then accesses the console server's serial port through an SSH session by passing the authorization key obtained from the DSView 3 server.

• The serial session begins.

To ensure constant connectivity, a DSView 3 server can be configured with an out of band (OOB) “back door” that will allow it to call a console server via modem in the event of a network or Internet failure.

Installing DSView 3 software with an OOB back door

The DSView 3 server must be running on hardware that has a connected modem, and the console server must have a built-in modem or access to a modem via a PCMCIA card, USB or serial port.

For this installation, the DSView 3 server must be the central point of reception of both the packets leaving the downloaded viewer and the console server. To ensure this, Proxy mode must be configured within the DSView 3 software. The viewer will then point to the DSView 3 server (not the console server) to establish the SSH connection. The DSView 3 server would then route the packets by changing both the source and destination IP addresses and act as a middle point of communication.

Under normal operating conditions, packets received from the Video Viewer would route through the DSView 3 server via Ethernet. In an error state, the DSView 3 server would detect that the normal path to the console server was interrupted and would dial out to the console server, pass authentication and establish a PPP connection.

Packets that would normally pass via Ethernet would instead be routed via PPP.

Because of the speed differences between Ethernet and dial-up, performance would be notably slower, but still present. Multiuser connections would further degrade performance and are not recommended. For this reason, dial-up backup is recommended as an emergency backup feature only.

Configuring dial-up for a console server

To configure dial-up to a console server within the DSView 3 software:

In a Units view window containing appliances, select the ACS 6000 console server you want to configure. For dial-in with callback, you must first select DSView Server - Properties - DSView Modem Sessions under the

System tab and enter the the phone number assigned to the DSView 3 server in the Analog Phone Number field.

Select DSView Settings - Dial-up, and click Enable Dial-up.

Select Modem Type - Analog.

Enter the phone number for the console server you want to use.

Enter the PPP User and select the PPP Auth Protocol in the appropriate fields.

For dial-in with callback, enable the dial-back checkbox.

Appendices

63

Select DSView Settings - Dial-up - PPP Password, then enter and confirm the password needed to access the

ACS 6000 console server.

Select DSView Settings - Dial-up - IP Addresses.

Click Generate Automatically to set the IP address automatically, or enter the PPP Local IP address and

Appliance IP address manually.

Select DSView Settings - Dial-up and click Save.

To configure a console server to receive the dial-up connection within the DSView 3 software:

In a Units view window containing appliances, select the ACS 6000 console server you want to configure.

For a modem attached to a serial port, select Ports - Serial Ports, then select the port that contains the attached modem. Click Set Dial-In.

-or-

For a modem attached to an auxiliary port, select Ports - Auxiliary Ports, then select the port. Click Set Dial-In.

-or-

For an internal modem, select Ports - Auxiliary Ports and select the modem.

-or-

For a pluggable device modem, select Pluggable Devices, select the modem and click Save.

Select DSView Settings - Dial-up and click Push Configuration.

The following step is only required if CHAP was selected in the PPP Auth Protocol field in the DSView 3 software Settings Dial-up window.

Log in to the console server’s CLI and access the Linux shell. Edit the /etc/ppp/chap-secrets and add a line in the format, where the first column should have the PPP user and the third column should have the PPP password as is shown in the following example: pppuser * "ppppassword" *

64 Cyclades™ ACS 6000 Advanced Console Server

Appendix E: Internal Modem

Some models of the ACS 6000 console server come equipped with an internal modem. This modem is used to originate and answer phone calls and establish communication with other modems to transmit data.

Controlling the modem’s functions is done by using the “AT” commands. These commands are used to instruct the modem to perform functions such as dialing or answering calls and are normally automatically issued by communication software. However, for some applications, custom software may have to be written due to the absence of a normal operating system.

The modem will automatically accept and process AT commands at most standard DTE (Data Terminal

Equipment) speeds and parity settings. For each command issued, the modem will respond with a result code to inform you of the modem’s status. The format of a basic AT command and result code is as follows:

AT<Command><CR>

OK

AT = Attention.

<Command> = any valid command

<CR> = Carriage Return or Enter key

OK = Result Code

Table E.1: Sample Command String

Command Description

ATDT7678900<CR> Instructs the modem to dial the number 7678900 and attempt to connect to the remote device.

There are basic codes the modem will issue in response to processing an AT command. Result codes may be displayed either in word (V1) or numeric (V0) format by using the Vn command. The Qn command controls if result codes are issued (Q0) or not issued (Q1). The Xn, Wn commands and register S95 determines which result code format the modem will display to indicate the type of connection established. There are more than 300 codes. The most commonly used are listed in the table below.

Table E.6: Basic Result Code Listing

Numeric Verbose Description

OK

RING

NO CARRIER

The modem has received and acknowledged the command.

Connection made at 300bps or extended result codes are off (X0).

An incoming ring signal has been detected.

This result code reflects either an intended disconnect or a failure to complete a connection.

ERROR An invalid command was issued to the modem.

CONNECT 1200 Indicates a 1200bps line or DTE connection.

NO DIALTONE

BUSY The modem has detected a busy tone.

NO ANSWER After S7 time has elapsed, the remote server never answered.

CONNECT 2400 Line speed or DTE connection at 2400bps.

CONNECT 9600 Line speed or DTE connection at 9600bps.

CONNECT 14400 Line speed or DTE connection at 14400bps.

CONNECT 19200 Line speed or DTE connection at 19200bps.

CONNECT 38400 Line speed or DTE connection at 38400bps.

CONNECT 57600 Line speed or DTE connection at 57600bps.

Digital line guard

The modem has an optional Digital Line Guard Circuit that automatically detects an over current situation on the Tip and Ring pins. When the modem goes off hook, it will immediately check the current on the Tip and

Ring pins. If the current exceeds 150 mA, the modem will display the “DIGITAL LINE DETECTED” result code and then go back on hook. The modem will continue to display this result code until normal current is detected on the Tip and Ring pins during an off hook condition. The DLG feature will protect the modem in case it is accidentally connected to a Digital Telephone Line.

Sleep mode operation

The modem can be set to enter the low power sleep mode by setting ATS24=n. In this case, “n” is time, in seconds, that the modem will operate in normal mode with no detected telephone line or DTE line activity before entering low power sleep mode. The timer is reset upon any DTE or telephone line activity. If S24 is set to zero, the modem will never enter the low power sleep mode.

Appendices

Disconnecting a call

There are several ways to disconnect a call. Below are the choices.

Resetting the modem’s power or toggling the Reset Line (Pin #12) will disconnect and put the modem back into the OFF line state.

An ON to OFF transition of the DTR signal (Pin #4) will also disconnect the modem. If you use this method, check to make sure that the DTR command is set to &D2 or &D3 and not forced (&D0).

The remote device can also cause the modem to disconnect. If the remote modem disconnects your modem will automatically sense the loss of the carrier signal and return to the OFF line state.

The ATH or ATZ commands can also be used to disconnect a call. In order to issue a command to the modem when it is On Line, the modem must be placed into the On Line Command State. This is accomplished by issuing a special escape sequence. The default value of this three digit escape sequence is the “+” character (see

S2 to change). The “+++” is protected by a one-second delay before and after it is sent (see S12 to change the time) When the modem detects the escape sequence, the OK result Result code will be displayed and the modem is in the On Line Command State. The ATH or ATZ command can now be issued to disconnect the call.

Selecting country codes

Setting the modem’s country code is done by with the +GCI command. To change to one of the 30 available countries, issue the AT+GCI=n command where “n” is one of the two digit country codes. This command must be issued each the modem is turned on. It will not automatically store or save this setting. It should be part of the Initialization string.

Example: AT+GCI=00<CR> Meaning: Change country code to Japan.

OK Meaning: The modem has accepted the command and is

now configured to operate in Japan

AT+GCI?<CR> Meaning: Display current country code

+GCI:00 Meaning: (Japan is the current country selected).

OK

To view which countries are available in the modems firmware, enter AT+GCI=?<CR>.

The modem will display all of the possible two digit country codes available.

Using caller ID

The modem can be used to display certain information about incoming telephone calls. The modem can inform you of the date, time, telephone number and name associated with incoming calls. When the CID option is enabled, information will be displayed between the first and second incoming “RING.” In order for this feature to work properly, the telephone line connected to the modem must subscribe to caller ID service offered by the local telephone company. A sample of the displayed information is shown below:

RING

DATE = 0513

TIME = 1346

NMBR = 408 767 8900

NAME = RADICOM RESEARCH
