Diagnostics

This chapter describes the ASM-60 diagnostic functions, which include:

• Status indications, alarms, power-up self-test

• VDSL performance diagnostics

• LED testing.

5.1 Error Detection

This section explains how to detect and fix errors and other problematic conditions
in ASM-60.

Power-Up Self-Test

ASM-60 performs a hardware self-test upon turn-on. The self-test sequence checks
the critical circuit functions of the modem.

Front-Panel LEDs

The status of ASM-60 is indicated by the ALM, TST, SYNC A and SYNC B
indicators located on the front panel. For the description of LEDs and their
functions, refer to Chapter 3.

Alarms

ASM-60 maintains two alarm buffers: temporary (up to 20 alarms) and permanent
(up to 100 alarms). The temporary alarm buffer is displayed by the ASM-60
management software as Alarms screen (see Figure 5-1), and the permanent alarm
buffer as Log File (see Figure 5-2).

An alarm enters simultaneously both Alarms display and log file, and the ALM LED
turns on to indicate the condition. But once the event that caused the alarm is
cleared, the alarm is removed from the temporary buffer, but it remains in the log
file, enabling you to view the alarm history.

IR-ETH Interface Module

IR-ETH is an interface module for RAD modems, used for converting the Ethernet
(10BaseT or 10Base2) electrical levels to the modem TTL levels. It also converts the
Ethernet protocol to HDLC to enable long-distance transmission and avoid the
Ethernet collision limitation.

IR-ETH includes an internal, self-learning Ethernet bridge, which enables a high
performance link between two Ethernet segments at a low transmission rate. The
low-speed HDLC transmission is sent over the link using the modem modulation
technique. It is converted back to an Ethernet signal at the remote modem.

Figure A-1 shows a typical application using an Ethernet interface bridge. Each
modem is connected to an Ethernet network via the Ethernet interface bridge.

Overview

Appendix C
IR-IP Interface Module

C.1 Introduction

IR-IP is a high-performance, miniature IP router based on RAD's unique IP router
chip, the ChipRouter.

IR-IP works by taking each Ethernet frame from the LAN and determining whether
the IP packet is destined for the IP net on the Ethernet LAN. If not, IR-IP forwards
the packet to the WAN (VDSL) link. IP packets received from the WAN link are
automatically forwarded to the LAN if the IP net matches.

IR-IP includes hardware filters which handle all filtering operations at wire speed
from both LAN-to-WAN and WAN-to-LAN, without dropping a single packet.
Filtering and forwarding are performed at the maximum rate of 35,000 and
30,000 frames per second (wire speed), respectively. The buffer can hold
256 frames of maximum size of 1534 bytes and a throughput latency of one
frame.

IR-IP is available with 10BaseT (UTP) interface and is fully
IEEE 802.3/Ethernet v2 compliant. The IR-IP interface can also operate in full
duplex Ethernet applications.

ASM-60 equipped with IR-IP interface module can be used as a Frame Relay
Access Device (FRAD) with an integral IP router. RFC 1490 is supported for a
single DLCI on the WAN link. Detection of the DLCI and the maintenance
protocol is performed automatically. This allows the IR-IP to be used as the
termination unit of IP services over Frame Relay at the customer premises,
opposite a Frame Relay switch in the backbone.

Alternatively, Point-to-Point Protocol (PPP) can be run on the WAN link with
automatic negotiation on power-up, as well as support for PAP and CHAP
authentication. With this feature, IR-IP can operate opposite any PPP compliant
access server or backbone router.

IR-IP supports HDLC, which is especially important for broadcast and multicast
applications where bandwidth overhead is critical.

IR-IP supports IP multicast at wire speed, making it suitable for any multicast
environment including high speed downstream environments, such as satellite and
xDSL. Users on the LAN who register with IR-IP for an IP multicast group using the
IGMP protocol filter IP multicast packets at wire speed.

Management and advanced configuration are performed via Telnet.

C.4 IR-IP Management Subsystem, General

Introduction

The IR-IP interface module management subsystem supports the following
functions:

• Preliminary configuration

• Configuration of management access parameters

• Advanced configuration of IR-IP parameters

• Collection and display of statistical performance data

• Maintenance functions, which include:

 Software downloading

 Resetting of various subsystems

 Display of error log

 Ping utility, for checking IP connectivity.

The management subsystem of the IR-IP interface module is a separate,
independent entity, and therefore it cannot be managed through the ASM-60
management subsystem.

The communication with the IR-IP management subsystem is made through the
local LAN interface connector of the IR-IP module, designated 10BASE-T, using
the Telnet protocol. Passwords can be used to prevent unauthorized access.

Accessing the IR-IP Management Subsystem

The IR-IP interface module must be configured in accordance with the specific
requirements of the user’s application before it can be used in the user’s network.
As a result, it is not possible to supply default parameters to enable IR-IP to start
service without any preliminary configuration.

Therefore, to enable the user to establish Telnet communication and configure
IR-IP, IR-IP is delivered with a default set of parameters. The default parameters
are automatically used:

• Before the IP router is configured by the user, e.g., when a new ASM-60 with
IR-IP interface module is put into operation

• After the user’s configuration parameters have been erased.

When the factory-default parameters are used, the ERR indicator located on the
ASM-60 rear panel, near the IR-IP Ethernet interface connector flashes rapidly
(about three times per second).

Note

The flashing of the ERR indicator also serves as a warning to the user that the IR-IP
WAN (VDSL) interface does not send, nor does it receive packets, and therefore IR­IP can be accessed only from the LAN.

After configuring IR-IP, it starts normal operation and routes the traffic in
accordance with the user-selected configuration parameters.

To change the parameters of an already-configured IR-IP, establish communication
from a Telnet host using the assigned IP address.

C-4 IR-IP Management Subsystem, General

ASM-60 Installation and Operation Manual Appendix C IR-IP Interface Module

Default IP Communication Parameters

The default IP communication parameters of the interface module are:

• The default IP address of the IR-IP Ethernet port is 192.168.205.1, and the
default IP subnet mask is 255.255.255.252.

• The port will accept IP communication only from the IP address

192.168.205.2. Therefore, as long as the factory defaults are in effect, you
must assign this address to the Telnet host used to configure IR-IP.

Using the IP learning mechanism, as explained below you can change the default
parameters.

Note

In the default configuration, the IR-IP WAN interface is disabled. In order to enable
the WAN interface, you have to modify the Ethernet port address or the IP subnet
mask.

C.5 Performing Preliminary Configuration

General

The software necessary for performing all the management and configuration
functions is stored in the IR-IP interface module, and therefore you only need a
regular Telnet host to perform all the activities described in this appendix.

A Telnet host is any computer, e.g., an IBM PC or compatible that fulfills the
following minimum requirements:

• A standard 10BaseT Ethernet interface

• A TCP/IP protocol stack, and therefore is capable of supporting IP

communication through the Ethernet interface

• Telnet client software

• A ping utility.

Outline of Preliminary Configuration

➤ To perform the preliminary configuration procedure:

1. Connect the Telnet host to the IR-IP interface module.

2. Configure the Telnet host to enable communication with the IR-IP interface
module using the default IP parameters.

3. Establish communication with IR-IP and assign the prescribed IP address to its
LAN interface.

4. Establish again communication with IR-IP and continue the preliminary
configuration in accordance with the Quick Setup Menu section below.

Performing Preliminary Configuration C-5

Appendix C IR-IP Interface Module ASM-60 Installation and Operation Manual

Connecting the Telnet Host

Before starting the management and configuration activities, it is necessary to
establish IP communication between your Telnet host and the IR-IP interface
module. For this purpose, it is necessary to provide a communication path.

Because of the method used to assign an IP address to IR-IP Ethernet port, it is
recommended to connect the Telnet host directly to the IP router 10BASE-T
connector. This is made by connecting an Ethernet cross cable between the
Ethernet connector of the Telnet host and the IR-IP connector.

However, you may also connect through a common LAN: in this case, connect
your Telnet host and IR-IP to Ethernet hub ports using straight cables.

Preliminary Telnet Host Configuration

You can use the IP learning mechanism to configure the IP communication
parameters of the IR-IP LAN interface. In this case, skip to the Assigning the Router
LAN Interface Address section below.

If you prefer to use the factory-default parameters to establish IP communication
between your Telnet host and IR-IP, configure the Telnet host as follows:

1. Temporarily configure the host IP address as 192.168.205.2.

2. The initial destination IP address to be used by the host is 192.168.205.1.

Note

The first step in the preliminary configuration process is to assign the desired IP
address to the LAN interface of the IR-IP interface module.
After an IP address is assigned and saved, you must change the destination IP
address of the Telnet host to the new address, otherwise it is not possible to
continue the configuration process. At the same time, you can also change the
temporary IP address assigned to the host (192.168.205.2) back to its permanent
address.

Assigning the Router LAN Interface Address

The IP address of the IR-IP LAN interface must be configured as part of the
preliminary configuration process. To simplify this process, IR-IP includes a simple
and convenient IP address learning mechanism.

The IP address can be configured and changed at any time, even after the
complete IR-IP configuration process has been performed, because it does not
affect other configuration parameters. Moreover, the IP subnet mask is
automatically adapted to the new IP address.

IP Learning Mechanism

To simplify the configuration process, IR-IP has a special mechanism for
configuring the IP address of its LAN interface. Setting section 1, called IP address
learning, of the IR-IP DIP switch (Figure C-3) to ON enables this mechanism.

The IP learning mechanism enables IR-IP to learn its LAN interface IP address by
receiving frames sent by a ping utility to the prescribed LAN IP address.

Note

C-6 Performing Preliminary Configuration

To use the IP learning mechanism, you do not need to know the current address of
IR-IP LAN interface, but only the prescribed IP address.

ASM-60 Installation and Operation Manual Appendix C IR-IP Interface Module

The IP address is actually retrieved from the ARP frames sent during pinging to
locate the ping destination, not from the ping frames.

To ensure that the process is correctly performed, it is recommended to check the
contents of the ARP table before starting the ping utility, to make sure that it does
not contain the address to be assigned to the IP router LAN interface.

➤ To view and edit the ARP table contents:

If the Telnet host you are using runs under Microsoft Inc. Windows ™ 95, 98 or
NT, use the following procedure to view and edit the ARP table contents:

1. Display the table using the

arp -a

command.

2. If the table includes the intended IP address, remove it from the table using
the

arp -d

command.

If for some reason the IP learning process does not succeed, before repeating it
make sure to remove the IP address from the table.

Assigning a LAN IP Address to a New IR-IP

The following procedure enables you to configure the LAN IP address of a new
IR-IP router, i.e., a router using the default parameters (see the Accessing the IR-IP
Management Subsystem section above).

If ASM-60 is already operating, skip Step 2 in the following procedure.

➤ To configure the IP router LAN address:

1. Make sure the preparations described above have been completed, including
the configuration of the ping utility.

2. Turn ASM-60on and monitor the IP router indicators:

 The INT indicator turns on

 The ERR indicator lights steadily for approx. 15 seconds, and then starts

flashing at a rapid rate (about three times per second).

If the ERR indicator turns off, skip to the What to Do If ... section below.

3. Set section 1 of IR-IP DIP switch to ON.

The ERR indicator starts flashing faster (approximately four times a second).

4. Send a ping to the new address to be used by IR-IP. A confirmation should be
received after the third ping: after the confirmation, the flashing will slow
down to approximately twice a second.

If your host does not begin to receive ping replies after three unsuccessful
attempts, skip to the What to Do If ... section below.

5. Return section 1 of the IR-IP DIP switch to the OFF position.

The ERR indicator must turn off.

At this stage, the communication with IR-IP router is lost, because its IP address
has been changed. Therefore, you must reconfigure the destination IP address of
the Telnet host. If you wish, you may also change the temporary IP address
assigned to the host (192.168.205.2) back to its permanent address.

Performing Preliminary Configuration C-7

Appendix C IR-IP Interface Module ASM-60 Installation and Operation Manual

After changing the destination IP address of the Telnet host, it is recommended to
turn ASM-60 off for a few seconds and then back on, before continuing the
configuration of the IP router in accordance with the Quick Setup Menu section
below. At this time, in Step 2 the ERR indicator turns off after the 15-second
interval.

Changing the LAN IP Address of a Configured IR-IP

The LAN IP address of an already-configured IR-IP can be changed while it
operates, this means it is not necessary to turn ASM-60off before starting the
configuration procedure. Note however that the IP traffic flow through IR-IP will
be disrupted until the other stations in the IP network learn the new address.

To change the LAN IP address of an already-configured IR-IP, use the procedure
described above for a new IR-IP with the following differences:

1. Configure the destination address of the ping utility to the new LAN interface
IP address. It is not necessary to change the Telnet host source address.

2. When ready, set section 1 of the IR-IP DIP switch to ON.

The ERR indicator starts flashing faster (approximately four times a second).

3. Perform Steps 4, 5 of the procedure used for a new IR-IP.

What to Do If ...

➤ The INT indicator does not light immediately after ASM-60 is turned on

The IR-IP interface module does not receive power from the ASM-60 power
supply. Service is required.

Note

After the power-up process ends, the INT indicator shows LAN integrity. It may stay
turned off without indicating power supply failure.

➤ The ERR indicator does not light immediately after ASM-60 is turned on

IR-IP is faulty and must be replaced.

➤ After turn-on, the ERR indicator lights for 15 seconds and then turns off. ACT

does not light, and there is no response from IR-IP

No software loaded into IR-IP. Download software using the procedure described
in the New Software Download Menu section below.

➤ After turn-on, the ERR indicator lights for 15 seconds, and then turns off. ACT

lights from time to time, but there is no response from IR-IP

IR-IP has been configured. If you do not know the current IP address of the LAN
interface, erase IR-IP router configuration using the procedure given in the Erasing
User’s Configuration section below.

➤ No ping replies from IR-IP

If your host does not begin to receive ping replies after three unsuccessful
attempts, check the physical connection path between the Telnet host Ethernet
interface and the IR-IP 10BASE-T connector.

➤ The IP learning process is not successful

Check that the prescribed IP address does not appear in the ARP table.

Quick Setup Menu C-11

Appendix C IR-IP Interface Module ASM-60 Installation and Operation Manual

Default Gateway

Operation without Default Gateway

The IP interface module is intended to enable the extension of LANs through the
ASM-60 VDSL link. Therefore, its default routing operation is different from the
default routing operation of standard IP routers:

• IR-IP forwards packets with destinations not located on the local LAN through
the WAN interface

• Packets received from the WAN interface and destined to hosts located on the
local LAN are forwarded to the LAN; other packets are discarded.

The default operation is used when the Default Gateway field is blank.

Operation with Default Gateway

You can instruct IR-IP to send packets with destinations not located on the local
LAN to a specific router, which is called the default gateway. The default gateway
must be connected to the local LAN.

To use this option, enter the IP address of another router attached to the local LAN
in the Default Gateway field.

Note

It is very important to obtain the correct parameters from the system administrator
or ISP. The most common problem when establishing an IP connection is incorrect
configuration of IP parameters and default gateway. Do not try to guess these
parameters.

Read Protocol from DIP Switches

Selecting YES for this parameter forces IR-IP router card to use the WAN protocol
selected by section 2 of its DIP switch: PPP or Frame Relay.

If you want to be able to select the WAN protocol by means of the Protocol field
(parameter 7) of the Quick Setup menu, select NO.

Protocol

Used to select the WAN protocol to be used by the IP router card: PPP, HDLC or
Frame Relay.

This parameter is available only if the Read Protocol from DIP Switches parameter
is set to NO.

C.13 Erasing User’s Configuration

The user-defined configuration parameters are stored in the IP router card flash
memory. After the user-defined configuration parameters are erased, the IP router
card automatically loads the default parameters.

You may want to erase the current configuration parameters:

1. Before IR-IP is prepared for operation in a new application.

2. When you cannot configure IR-IP because its current LAN-interface IP address
and/or the Telnet password, are not known.

➤ To erase the user’s configuration:

1. Turn ASM-60 off.

2. Set all the four sections of the IR-IP DIP switch (Figure C-3) to ON.

3. Turn ASM-60 on and monitor the ERR indicator: it must turn on and light
steadily.

4. While the ERR indicator is lit (within 15 seconds), set sections 1 and 2 of the
DIP switch to OFF.

The IP router configuration is erased.

Note

If you do not set sections 1 and 2 to OFF within 15 seconds of power-up, the IP
router card ignores the setting of all the four sections to ON and starts normal
operation. In this case, it is recommended to turn ASM-60 off and then back on.
To abort the whole operation, turn ASM-60 off, return all the four-switch section to
the desired positions, and then turn ASM-60 on again.

5. Turn ASM-60 off, and the return all the four sections of the DIP switch to the
desired positions.

C.14 Erasing IR-IP Software

You may erase the IR-IP application software, without erasing the user-defined
parameters.

After the application software is erased, IR-IP starts its TFTP server application, and
waits for the downloading of software by a TFTP client connected to its LAN
interface. The procedure to be used to download the application software in this
case is also described below.

You may want to erase the application software if the downloading of new
software using the Device Control menu (see Figure C-16) fails, and IR-IP does not
function properly.

Erasing Application Software

➤ To erase the application software:

1. Turn ASM-60 off.

C-28 Erasing IR-IP Software

ASM-60 Installation and Operation Manual Appendix C IR-IP Interface Module

2. Set all the four sections of IR-IP DIP switch to ON.

3. Turn the ASM-60 on and monitor the IP router ERR indicator: it must turn on
and light steadily.

4. While the ERR indicator is lit (within 15 seconds), set sections 3 and 4 of IR-IP
DIP switch to OFF.

The IP router application software is erased.

Note

If you do not set sections 3 and 4 to OFF within 15 seconds of power-up, IR-IP
ignores the setting of all the four sections to ON and starts normal operation. In this
case, it is recommended to turn ASM-60 off and then back on.
Alternately, to abort the whole operation, turn ASM-60 off, return all the four
switches to the desired positions, and then turn ASM-60 on again.

5. Turn ASM-60 off, and the return all the four sections of the DIP switch to the
desired positions.

Downloading New Software

After erasing the application software, you can download new software from any
computer that can serve as a TFTP client.

To enable the downloading, IR-IP automatically activates its TFTP server
application with the following factory-default IP parameters:

• IP address: 192.168.205.1

• Subnet mask: 255.255.255.252.

Connect the computer serving as a TFTP client to the IR-IP 10BASE-T connector in
the way as a Telnet host used for preliminary configuration (see the Performing
Preliminary Configuration section). The computer IP parameters must be
configured as follows:

• IP address 192.168.205.2

• Subnet mask 255.255.255.252

• Default gateway 192.168.205.1

➤ To download new software:

1. If necessary, turn ASM-60 off.

2. Set all the four sections of the IR-IP DIP switch to OFF.

3. Turn ASM-60 on and monitor the ERR indicator: it must start flashing.

4. Connect the computer to the IP router LAN interface and configure its IP
parameters as explained above.

5. Run a standard TFTP client application on the Telnet host, and download the
appropriate software file.

If the download is successful, IR-IP starts using the new software.

If the downloading fails, repeat the download process.
