Connection of Data and Telecommunications Cables

Data and telecommunication interfaces are classified according to their safety status.

The following table lists the status of several standard interfaces. If the status of a given port differs from the standard one, a notice will be given in the manual.

xDSL (without feeding voltage), Balanced E1, T1, Sub E1/T1

Always connect a given port to a port of the same safety status. If in doubt, seek the assistance of a qualified safety engineer.

Always make sure that the equipment is grounded before connecting telecommunication cables. Do not disconnect the ground connection before disconnecting all telecommunications cables.

Some SELV and non-SELV circuits use the same connectors. Use caution when connecting cables. Extra caution should be exercised during thunderstorms.

When using shielded or coaxial cables, verify that there is a good ground connection at both ends. The earthing and bonding of the ground connections should comply with the local codes.

The telecommunication wiring in the building may be damaged or present a fire hazard in case of contact between exposed external wires and the AC power lines. In order to reduce the risk, there are restrictions on the diameter of wires in the telecom cables, between the equipment and the mating connectors.

Multiplexer Applications

Notes • The multiplexer unit cannot be configured as a device with LAN only port. It must have a DTE or IR port.

•The hardware of a single unit-based product with a LAN port manager is different from that of a multiplexer-based product.

The hardware has different options for the modem to work as a multiplexer.

Table 1-4 shows all the available multiplexer combinations that can be used.

Chapter 1 Introduction Installation and Operation Manual

Table 1-4. Possible Multiplexer Applications (Cont.)

Serial DTE = V.35, X.21, RS-530, IR-IP

The following are multiplexer conditions when working with the ASMi-52 unit:

•E1+Serial DTE can work as an ‘E1 port only’.

•E1+LAN can work as an ‘E1 port only’.

•LAN+Serial DTE can work as a ‘Serial DTE port only’.

•E1+Ethernet and Serial DTE+Ethernet can be configured as a single port only (‘E1 only’ or ‘Serial DTE only’) while the Ethernet port operates as a management port only.

ASMi-52 E1 or Serial DTE units with a LAN management port previously released with software versions earlier than version 2.5 cannot operate as a multiplexer unit (E1+LAN, Serial DTE+LAN) with version 2.5 due to hardware differences.

Timing

ASMi-52 supports three clock modes:

•Internal, derived from its internal oscillator (CO mode)

•External, supplied by the attached DTE

•Receive, recovered from the received line signal (CPE mode).

Management

ASMi-52 supports the following management options:

•ASCII terminal or Easy Config hand-held device via V.24/RS-232 terminal port

•Telnet via a dedicated 10/100BaseT port

•SNMP network management (RADview) via a dedicated 10/100BaseT port

•PC, running a Web browsing application (ConfiguRAD)

•Inband management via a dedicated timeslot (units with E1/T1 interface only).

EOC

ASMi-52 provides an inband management channel (EOC) for end-to-end system management and supervision. This management channel uses SHDSL overhead bits and operates without interfering with data transmission.

ConfiguRAD

ConfiguRAD is a user-friendly Web-based terminal management system used for remote device configuration and maintenance. It is embedded in ASMi-52 and provided at no extra cost. ConfiguRAD can be run from any standard Web browser.

Dial-In

Usually, preliminary configuration of the system parameters is performed via an ASCII terminal. Once the ASMi-52 host IP parameters are set, it is possible to access it via Telnet, ConfiguRAD, or RADview-Lite for further configuration.

•Remote management via out-of-band 10/100BaseT port or dedicated timeslot. Remote management is performed using Telnet, or ConfiguRAD (RAD’s Web-based application), or RADview (RAD’s SNMP-based management system).

Managing ASMi-52 via a Terminal Port

This section describes how to prepare ASMi-52 and the supervisory terminal for a control session.

Control Port Interface Characteristics

ASMi-52 includes a V.24 (RS-232) asynchronous DCE port, designated as CONTROL and terminating in a 9-pin D-type female connector. The control port continuously monitors the incoming data stream and immediately responds to any input string received through this port.

The terminal can be connected either directly to the ASMi-52 control port, or through a modem or any other type of full-duplex data link. The ASMi-52 control port interface type must be set in accordance with the connection method, as follows:

•DCE – direct connection to terminals. Since terminals usually have DTE interfaces, the connection to the port is made by means of a cable.

•DTE – connection through a modem or data link. In this case, you need a cross-cable (also called a null modem cable) to connect to the CONTROL connector.

The ASMi-52 control port can be configured to communicate at the following rates: 9.6, 19.2, 38.4, 57.6, or 115.2 kbps.

The word format consists of one stop bit, 8 data bits, and no parity.

Note ASMi-52 can also be managed via a hand-held control device, Easy Config. Refer to Appendix C for detailed description of the device.

Preparing the Terminal

Any standard ASCII terminal (a “dumb” terminal or a personal computer running a terminal emulation application) equipped with a V.24 (RS-232) communication interface can be used to configure ASMi-52. Appendix A details the pin assignments and control signal directions of the ASMi-52 control connector.

Data Terminal Ready (DTR)

When connected and turned on, the terminal sets the DTR line ON (active) to gain control over ASMi-52 and starts a configuration or monitoring session.

Initiating a Control Session

To initiate a control session:

1.Connect the terminal cable to the CONTROL connector of ASMi-52.

2.Turn the control terminal on.

3.Configure the terminal to the default communication parameters: 9.6 kbps, one start bit, eight data bits, no parity, one stop bit, VT100 emulation.

4.Select the full duplex mode.

5.Turn the terminal echo off.

6.Disable any type of flow control.

You are now ready to start a control session.

Navigating the Management Menus

This section provides a general description of the software menu operation and conventions for navigating the menus.

Choosing Options

To choose an option:

• Type the number corresponding to the option, and press <Enter>. The screen for the selected option is displayed.

•

When a menu option has only two values, typing the option number and pressing <Enter> will scroll between the available values.

Managing ASMi-52 via a Dedicated Timeslot

ASMi-52 modems with E1 or T1 interface can be managed via a dedicated E1/T1 timeslot (DTS) (see Figure 3-9).

The DTS is a management channel that connects directly to the ASMi-52 host using a separate IP interface, i.e., separate IP address and IP mask. If the LAN and dedicated timeslot services are configured to have the same IP, the management

session over the dedicated timeslot has priority over management via the 10/100BaseT port.

1.Connect the E1/T1 line to the ASMi-52 E1 or T1 port.

2.Start a terminal management session and do the following:

ConfiguRAD is a Web-based remote access terminal management software. It provides a user-friendly interface for configuring, collecting statistics, and performing diagnostic tests on the ASMi-52 units.

To choose an option:

1.Click a link in the ConfiguRAD screen to display the next menu.

2.Once the target screen is displayed, select a value from the drop-down box or enter a value in a text box.

Some of the ASMi-52 menus have a ‘Save’ option. When choosing options from these menus, you must confirm your choice by selecting ‘Save’, otherwise your entry will be ignored.

At the left-hand bottom corner, ConfiguRAD provides some auxiliary management tools:

•Status – shows the number of users currently managing ASMi-52

•Trace – opens an additional pane for system messages, progress indicators (ping, software and configuration file downloads) and alarms. It is recommended to keep the trace pane open all the time.

•Refresh All – refreshes all screen elements.

Configuration Menus

The following is the menu map of the ASMi-52 management software.

Note Some of the management menu options depend on the type of the DTE interface installed in ASMi-52:

•DTS Configuration (Main menu > Configuration > System Configuration > Management) is available only for the units with E1 or T1 interface.

•LAN Rate (Main menu > Configuration > LAN Configuration > Local LAN Configuration) is available for the units with the user’s 10/100BaseT port.

•Data Rate (Main menu > Configuration > DTE Configuration > DTE Remote Port) is available for the units with a serial DTE interface.

•E1 Configuration (Main menu > Configuration) is available for the units with an E1 local port.

•Figure 3-10 illustrates software menus of the unit that operates with SHDSL repeater in the line.

To end the current session:

•In the Main menu, click Logout or type & in a terminal management screen.

•

•ASMi-52 allows at least four management sessions to be active at a time. If the Web-based management sessions were not ended properly (for example, by closing the Web browser window), you have to wait five minutes before attempting the next log-in. If you try to log in during the five-minute security timeout, ASMi-52 does not allow to proceed to the Main menu, displaying ‘Too Many Users’ message. Likewise, the Web-based management session cannot be initiated, if a terminal or Telnet session is still in progress.

•One session is always reserved as a terminal session from the four available management sessions, the other three sessions can be a ConfiguRAD or Telnet sessions. The four sessions can function at the same time.

3.5 Turning Off ASMi-52

To turn off ASMi-52:

•Remove the power cord from the power source.
