1 • Introduction mDSL DACS Administrators’ Reference Guide
Introduction
You may configure the Digital Access and Cross-Connect System (DACS) by using its internal HTTP/HTML
Administration Pages. However, to enter into the HTTP/HTML pages, you must first define the LAN Address
Technique, LAN IP Address, and LAN Subnet Mask for the DACS. If you have not done so, please refer to the
Getting Started Guide that came with your DACS.
Logging into the HTTP/HTML Administration Pages
To log into the HTTP/HTML Administration pages, you must enter the 4-octet Internet Protocol (IP) (for
example, http://your.server.ip.address) address as the Universal Resource Locator (URL) into a World-Wide Web
(WWW) browser. After you enter the IP address, the DACS will ask for your user name and password as
shown in figure 1.
Figure 1. DACS login window
Your DACS will accept the following default administrative passwords:
• superuser—this password carries full permission to change and view any parameters in the DACS
• monitor—this password allows full viewing of any non-password oriented variables.
Note For security reasons, we recommend that you change these passwords
immediately after initial configuration.
HTTP/HTML and SNMP Object Format
In this document, we shall describe the variables found on each of the internal HTTP/HTML pages. This
description will include brief definitions of the Patton Enterprise MIB or SNMP MIB II object identifiers
wherever applicable. The format of the variables will resemble figure 2.

Operating Status Variables
There are seven system variables which describe the immediate operating status of the DACS. These variables
are shown in figure 4 and are described in the following sections.
Figure 4. STATUS menu
Egress Card Installed (boxEgressType)
Three parameters define whether an egress card is installed in the 3095 and if so, which one. The parameters
are as follows:
• none(0)—No egress card is installed
• pmc-t1-e1(1)—T1/E1 WAN port card is installed
• pmc-serial(2)—V.35 serial interface card is installed
Number of Egress Ports (boxEgressCount)
Defines the number of ports on the egress card module installed in the system.
% CPU Idle (boxIdleTime)
This is an indication of the amount of system CPU power which is not being utilized by the Model 3095. The
returned value is a percentage of free CPU cycles since the last time the variable was read.
Running Since Last Boot (sysUpTime)
The time (in hundredths of a second) since the DACS was last power-cycled.
Total System Alarms (alarmTotal)
Total number of alarms currently active in the system.
Operating Status Variables 25

Immediate Actions
There are several immediate actions (see figure 5) in superuser mode which will cause the DACS to operate
according to the descriptions in the following sections.
Figure 5. Immediate Actions buttons
Record Current Configuration (storeConfig(1))
This feature saves the current configuration in permanent FLASH memory. In other words, configuration
changes made in the subsystem web pages become permanent when you select Record Current Configuration.
1. Configuration changes in the DACS are made in the subsystem web pages by clicking Submit Query.
This stores the configuration in volatile DRAM (Dynamic RAM) only. Since the Submit Query changes
take immediate effect, the administrator can test different configuration parameters without needing to
change the FLASH configuration at this moment.
2. Without clicking on Record Current Configuration, all configuration changes will be lost if the power
is recycled. After doing the Record Current Configuration save, the current configuration of the DACS
will not be lost with power cycling.
Note The most important step after completing the configuration is to save it in
permanent memory by clicking on Record Current Configuration.
Hard Reset (hardReset(2))
This button causes the DACS to perform a cold restart. When you select Hard Reset, the DACS requests
confirmation for the execution of this command. Then, the DACS will disconnect all current sessions, re-initialize the interfaces, and re-load configuration parameters from FLASH.
Set Factory Default Configuration (forceDefaultConfig(3))
This button clears out the configuration in FLASH and loads the factory default parameters into FLASH
memory. The factory default settings will not execute on the DACS until it is re-booted, for example by doing
a Hard Reset.
Note Set Factory Default Configuration will delete the DACS’s Ether-
net IP address and any other site specific settings made for your particular installation. You will have to re-enter the DACS’s Ethernet IP
address and netmask using the front panel control port in order to use
the HTTP/HTML Management pages.

Introduction
The Import/Export function enables you to make a backup (or export) copy of your DACS’s configuration
parameters. By exporting the configurations, the saved files can quickly be loaded, or imported, into a replacement DACS—greatly speeding up the installation process should an DACS need replacing.
Note All actions for Import/Export require superuser access privileges.
To import or export a configuration, click on
Import/Export main window (see figure 6).

6 • Alarms mDSL DACS Administrators’ Reference Guide
Introduction
The DACS has an extensive alarm reporting system which enables users to configure, monitor, and test major
and minor alarms. The alarm system can be set to notify of equipment failures (for example, a power supply
failure) or T1/E1 port malfunctions. The alarms that can be configured by the system administrator to generate
alerts based on the condition of the DACS.
Displaying the alarms window
Click on Alarms under the Configuration Menu to display the Alarm System main window (figure 11).
Note The system administrator can manually generate a specific alarm for
testing purposes or clear the alarm counters from the main window.
Figure 11. Alarms main window
40 Introduction
mDSL DACS Administrators’ Reference Guide 6 • Alarms
The mDSL Multiplexer has four methods to notify an alarm condition:
1. Front panel LED—The front panel ALARM LED has three states that indicate the presence and severity
of an alarm. The states are:
- Off—No alarm present
- Solid—Minor alarm
- Flashing—Major alarm.
Note The POWER LED will flash if a power supply failure alarm is
present. If both power supplies are functioning normally, the LED
will be lit constantly. Otherwise, the LED will flash.
2. Administration web page indication—The Alarms window of the administration page uses red highlighting to indicate which items are in an alarm state (see figure 12).
Figure 12. Sample alarm indication
3. SYSLOG/SNMP—For external notification, the DACS can be configured to send a SYSLOG message or
an SNMP TRAP to an external management host. To configure the alarm response for either SNMP Traps
or SYSLOG messages, click on the
Alarm Response link (go to “Alarm Parameters” on page 44).
4. Alarm Relay—Located on the rear of the chassis, the Alarm Relay is a 3-position terminal block. The
Alarm Relay may be configured to indicate when a major alarm, a minor alarm or both major and minor
alarms occur. It may also be disabled. The 3-position terminal block numbers its pins from 1 to 3 from left
to right. When no alarms are indicated, pins 1 and 2 are normally closed and pins 2 and 3 are normally
open. Upon the occurrence of an alarm—the type is configured as major, minor, or both—pins 1 and 2 are
open and pins 2 and 3 are closed.
Besides enabling a user to view current alarm status, you may manually generate an alarm as a test and clear the
alarm time and count variables. The Alarms main window also contains links to the following:
• Modify Response—for configuring how the Alarm Response Outputs notify administrators of an alarm (see
“Alarm Parameters” on page 44)
• Modify Alarms—Clicking on this link takes you to a window where you can configure the importance or
severity of each individual alarm. The severity of the alarm type may generate a minor, major, minor self-

alarm severity levels” on page 46)
Alarm Response Outputs
Alarm Response Outputs display the current setting for handling alarm notification via the different Alarm
Response Outputs. To change the Alarm Response Outputs parameters, refer to “Alarm Parameters” on
page 44.
Relay Response (alarmRlay(1))
The relay of the Alarm Port on the rear of the chassis will be activated when a major, minor, or both major and
minor alarm is generated. The Alarm Port may also be disabled.
Minor Alarm SYSLOG Priority (minorSyslogPriority)
Sets the priority of the minor alarm SYSLOG message that will be generated upon the occurrence of a minor
alarm.
Major Alarm SYSLOG Priority (majorSyslogPriority)
Sets the priority of the major alarm SYSLOG message that will be generated upon the occurrence of a major
alarm.
Minor Alarm SNMP Trap IP [address] (minorTrapIp)
Displays the IP address of a SNMP management station for receiving the SNMP trap messages upon the
occurrence of an active minor alarm. The SNMP trap messages are sent in UDP datagrams. When the IP
address is set to 0.0.0.0, no trap messages will ever be sent.
Major Alarm SNMP Trap IP [address] (majorTrapIp)
The same function as the Minor Alarm Trap IP except for only the occurrence of active major alarms.
Temperature Threshold (boxAlarmTemperature)
An alarm will be generated when the box temperature exceeds this temperature value in degrees Celsius.
Current Box Temperature (boxTemperature)
The internal temperature in the box in degrees Celsius.
Clear All Alarms
Click on this button to clear all the alarms (that is, to reset all the alarms). This clearing action will, for all the
alarms, reset the alarm, reset Time Since Alarm to 0.00 seconds, and reset the Alarm Count to 0 (zero).
Alarms
This portion of the Alarms main window displays the alarm status table, where you can view current alarm status, manually generate an alarm as a test, and clear the alarm time and alarm count variables.
Alarm ID (alarmDefIndex)
This identifies the alarm item by a numerical index.
42 Displaying the alarms window
mDSL DACS Administrators’ Reference Guide 6 • Alarms
Alarm Name (alarmName)
The alarm items are grouped into two categories: system and WAN trunk alarms. The system group category
lists DACS temperature and power supply status. The WAN category monitors the T1/E1 ports for yellow and
red alarms.
Alarm Severity (alarmSeverity)
Used for selecting the type of alarm that is generated by a particular event. The four types are:
• Minor
• Major
• Minor self-clearing
• Major self-clearing
The setting can also be disabled (set to ignore an alarm)
Alarm Time (alarmTicks)
The Alarm Time column displays the number of seconds the alarm has been activated.
Alarm Count (alarmCount)
The Alarm Count column indicates how many times the alarm has occurred and is useful for monitoring selfclearing alarms.
Generate Alarm (alarmGenerate(1)
For testing purposes, clicking the Generate Alarm button next to each alarm name will cause that alarm condition to be activated.
Clear Alarm (alarmGenerate(2)
Clicking the Clear Alarm button resets the alarm to a non-alarm condition.

Alarm Parameters
The Alarm Status Table on the Alarm System main page displays the current alarm status. You may also manually generate an alarm as a test and clear the alarm, the alarm time and the alarm count variables.
• Alarm ID—The Alarm ID identifies the alarm numerically. (For example, Alarm ID #2 identifies the alarm
named “Box: Power Supply I Failed.” )
• Alarm Name—The alarm items are grouped into three categories: Box, WAN, and mDSL alarms. The Box
alarm group contains the alarms “Over Temperature” and “Power Supply Fail” for each of the two power
supplies. The WAN alarm group includes yellow and red alarms. The mDSL alarm group has Line Down,
Bit Error, and Hardware Failure alarms for each mDSL modem link.
• Alarm Severity—For each alarm, it shows whether the alarm is disabled or configured to generate a major,
minor, major self-clearing, or minor self-clearing alarm.
• Time Since Alarm—Elapsed time since the alarm occurred (in seconds).
• Alarm Count—The number of times this alarm has occurred since it has been cleared. It is also for moni-
toring self-clearing alarms.
• Generate Alarm—For testing a particular alarm, click on Generate Alarm. This activates the alarm as if the
actual trigger event had occurred.
• Clear Alarm—Clearing the alarm resets the alarm, resets Time Since Alarm to 0.00 seconds and resets
Alarm Count to 0 (zero).
Types of Alarms
• Box Alarm Group
- Box: Over Temperature—When the internal box temperature exceeds the temperature threshold under
Modify Response…, an alarm will be generated.
- Box: Power Supply I–II Fail—An alarm will be generated if a power supply fails or if the power source for
the supply fails or is disconnected.
• WAN Alarm Group
- WAN 1–16: Yellow Alarm—When a WAN port sees a yellow alarm, the specific WAN alarm will be sent.
44 Displaying the alarms window
mDSL DACS Administrators’ Reference Guide 6 • Alarms
- WAN 1–16: Red Alarm—When a WAN port sends a red alarm, the specific WAN alarm will be sent.
• mDSL Alarm Group
- mDSL 1–16: Line Down—When an mDSL modem line is down, an alarm is generated.
- mDSL 1–16: Bit Error—When the bit error for an mDSL modem connection exceeds a particular value,
an alarm is generated.
- mDSL 1–16: Hardware Failure—When an internal mDSL modem has a hardware failure, an alarm is
generated.
Modify Response—Configuring the alarm response system
The alarm response outputs refer to points of external notification. Note that the front panel Alarm LED and
the web administration pages will always indicate an occurrence of an active alarm. To configure each alarm
response output, click on
the alarm response output that you want to configure with the pull down menu. After configuring a specific
alarm response output, remember to click on Submit Query before going to the next alarm response output;
otherwise the change will not occur.
Relay Response (alarmRelay(1))
The relay may be set to go active for minor alarms, major alarms, or both. It may also be disabled with the
parameter “none.”
Modify Response. The Alarm Response System page appears (see figure 13). Choose
Minor Alarm Syslog Priority (minorSyslogPriority) & Major Alarm Syslog Priority
(majorSyslogPriority)
When a minor/major alarm occurs, a message of the selected priority is sent to the Syslog engine. The Priority
levels are priorityDisable(100), prioritySystem(80), priorityService(60), priorityOddity(40), priorityInfo(20),
priorityDebug(10), and priorityVerbose(5). For more information on Syslog messages, refer to Chapter 20,
“System Log”.
Minor Alarm SNMP Trap IP [address] (minSyslogPriority)
Upon the occurrence of a minor alarm, an SNMP Trap message is sent to a host system (or a management station). This parameter is the IP address of the host running the SNMP Trap daemon. When the IP address is set
to 0.0.0.0 no SNMP Trap message will be sent.
Major Alarm SNMP Trap IP [address] (majorSyslogPriority)
This parameter functions in the same manner as the Minor Alarm SNMP Trap IP [address] except it applies to
major alarms. Upon the occurrence of a major alarm, an SNMP Trap message is sent to a host system (or a
management station). This parameter is the IP address of the host running the SNMP Trap daemon. When the
IP address is set to 0.0.0.0 no SNMP Trap message will be sent.
Temperature Threshold (boxAlarmTemperature)
An alarm message is generated when the internal box temperature exceeds this threshold value (degrees Celsius). You can change the threshold temperature, but we recommend that you use the factory default.

Modify Alarms—Configuring alarm severity levels
Clicking on Modify Alarms window (see figure 14) displays a table listing each individual alarm. From this
page you can configure the severity for each alarm (such as major, minor, major self-clearing, and minor selfclearing). Each alarm can be disabled as appropriate for your application.
Figure 14. Modify Alarms settings window
The alarms can be independently configured to generate alarm messages. Each alarm item can be set for one of
the following severity levels:
• Ignore(0)—Do not generate an alarm.
• Minor(1)—Generate a minor alarm that will not reset until the administrator manually clears it.
• Major(2)—Generate a major alarm that will not reset until the administrator manually clears it.
• MinorSelfClearing(3)—Generate a minor alarm that automatically clears after 30 seconds. If the alarm con-
dition has not ceased, the alarm will be automatically cleared, but another alarm will be immediately gener-

ated. If the alarm condition has ceased, the alarm will be automatically cleared after the same fixed period of
time.
• MajorSelfClearing(4)—Same as MinorSelfClearing(3) except that it is a Major alarm instead of Minor.
Note For maximum application flexibility, the administrator shall choose
which constitute major or minor alarm. Some examples of typical
major and minor alarms include:
- Box: Over Temperature—Major Alarm
- mDSL 10: Bit Error—Minor Alarm
- WAN 1: Red Alarm—MajorSelfClearing
- WAN 1: Yellow Alarm—MinorSelfClearing

Introduction
One of the remote locations is the CPE’s mDSL modem. The second remote location is typically connected
through some WAN port’s time slots. For communication between these remote locations they shall be connected together within the DACS. These connections are configured in the DS0 mapping window.
The following types of internal connections are available:
• Between an mDSL modem and time slots in a WAN port
• Between two mDSL modems
• Between time slots within the same or between different WAN ports
Note When the text in this document refers to a 16-modem DSL, the ref-
erence applies equally to the 8-modem mDSL version as well.
Displaying the DS0 Mapping window
Do the following:
1. Click on
DS0 Mapping under the Configuration Menu. The DS0 Mapping Configuration window dis-
plays (see figure 15).
Figure 15. DS0 Mapping Configuration window
The following sections describe the contents of the DS0 Mapping Configuration window.
DACS Display Type
You can configure or map the static connections by using the Long Format or the Command Line Format.
• displayLongForm(0)—This is the easiest to use by selecting the options from the pull-down menus.
• displayCliForm(1)—If you prefer the command line format, select displayCliForm(1) and click on the Sub-

50 Introduction
mDSL DACS Administrators’ Reference Guide 7 • DS0 Mapping
Help (DACS help information)
Clicking on the Help button displays the DACS Help Information window (see figure 16). The purpose of
this window is to help the user learn how to add DS0 connections using the DACS HTML pages. This window define all of the parameters available within this web page. If you are using the Command Line Format to
make connections, scroll down the window to the heading
Command Line Format. The information contained
in the Help window is also covered in this chapter.
Figure 16. Example DACS Help Information window
Static Connection
Pull Down Menus
Each pull down window signifies part of a connection. Each connection is made up of an "A" side and a "B"
side. These names have been arbitrarily chosen and do not signify the direction that data will travel. All data
will be bi-directional. There are three parameters that need to be defined for each connection, they are:
• Device Type
• Device Number
• Device Slots
ID (daxConnectionID)
Then ID number identifies each mapping with a unique number. The number is automatically assigned
sequentially when a static connection is entered. The ID number begins at “1.”
Device Type (daxDeviceTypeTomDSL) (daxDeviceTypeFrommDSL)
The Device Type specifies the physical interface that you will be connecting. Within the 3095 the user has the
option of selecting either a T1/E1 WAN line or an mDSL modem. While the one side may be a T1/E1 WAN
line and the other an mDSL modem, note that both sides of the connection can be T1/E1 or both sides can be
mDSL. The two Device Types are t1-e1(1) and mDSL(3).
Device Number (daxDeviceNumberTomDSL) (daxDeviceNumberFrommDSL)
The next step in creating a connection through the DACs is to select the port that you would like to use. This
corresponds to the Port Number for the devices selected in the previous step. For example, if you would like to
make a connection to mDSL Port 3 (referring to mDSL modem #3), then select "Port 3" in the "Device Number" field. Note that there are 16 t1-e1 ports. Since there are either 8 or 16 mDSL modems within the 3095,
you may choose any of the 8 or 16 ports.
Displaying the DS0 Mapping window 51
7 • DS0 Mapping mDSL DACS Administrators’ Reference Guide
Device Slots (daxDeviceSlotTo) (daxDeviceSlotFrom)
The “slots” input identifies the DS0 channels—each DS0 channel is 64 kbps—that you would like to connect.
Each mDSL modem has up to 31 DS0 channels. Each time slot in a T1 or E1 WAN port has 24 or 31 DS0
channels, respectively. When selecting the slots you must select the same number of slots on the “A” and “B”
side of the connection. The slots are selected by entering a string that represents the slots. For the mDSL ports,
slots 1–31 are available. For a WAN port configured as a T1, the available slots are numbered from 1–24. For a
WAN port configured as an E1, the available slots are 1–31. The following notation should be used for entering the slots. Several examples are given below.
• dash: (-) 1 - 4
• comma: (,) 1,4,9
• combo: 1 - 2, 3,6 - 7
For example, to connect a T1 Port using timeslots 1,2, 5, 6, 7, and 15, you can input any of the following
strings:
1,2, 5-7, 15
1 - 2, 5,6,7,15
1 - 2, 5 - 6, 7, 15
Note Only contiguous timeslots beginning at 1 are available in the mDSL
modems.
Configuration
The user can make connections in the box using two different methods. The easiest way is by using the pull
down windows provided. But the user can also add connection using the command line format by entering a
text string. To input a static connection into the box using the text string. Use the following convention:
• DeviceA:PortA:SlotsA/DeviceB:PortB:SlotsB
Device Options - The interface that you would like to select
1) t1-e1
2) mDSL
Port Options - The Port Number (starting at 1) may be one of the 16 WAN ports or one of the 16 mDSL
modems. To configure Slots (DS0 channels), choose the slots that you would like to use. The following
notations are allowed:
1) dash (-): 1 - 4
2) comma (,): 1,4,9
3) combination of dashes and commas: 1 - 2, 3,6 - 7
Example #1: To connect a T1 line, (WAN) Port 1, timeslots 1–24 to an mDSL modem, Port 3 (modem
#3), timeslots 1,2, input the following string:
t1-e1:1:1 - 24/mDSL:3:1 – 24

Introduction
Click on Clocking in the Configuration Menu to display the System Clocking Configuration main window
(see figure 17).
Figure 17. System Clocking Configuration window
The Clocking window is where the primary and secondary clocking sources that synchronize all DS0 channels
are configured. The DACS uses a single clock source for all DS0 channels. You select the clock for the DS0
channels from the following clock sources:
• An internal oscillator
• Any of the WAN ports
• Any of the mDSL remote modems
• An external clock (accessed via the Ext. Clock 3-position terminal block located on the rear panel of the
DACS.”
Main Reference setting determines the clock source if this source is operational. If the Main Reference
The
clock source fails, the
Fallback Reference becomes the clock source to synchronize all DS0 channels. The
clock source is the system clock for the entire DACS.
Configuring the System Clock Settings
The following sections describe configuring the clock settings.
Main Reference (daxClockMainRef)
The Main Reference and Fallback Reference parameters have the same selections for system clock. Make sure
you choose different clock sources for the Main Reference and Fallback Reference. The following settings
are available:
• none(0)—No clock selection.

mDSL DACS Administrators’ Reference Guide 9 • mDSL Port Configuration
Introduction
The mDSL subsystem in the Configuration Menu contains web pages showing the status of all mDSL ports.
They summarize information about the mDSL modem links between the 3095 and the CPE mDSL modems,
also providing the ability to configure certain of the mDSL parameters. The information may be display-only
fields or user-entry fields.
Note The Model 3095 is available with 8 or 16 mDSL ports. References in
this manual to the 16-port version apply to the 8-port version as well.
The summary information above the table shows how many mDSL modems are in the different states. The
states are number of mDSL modems available, failed, activated, connected, and in a test mode.
The table shows the characteristics for each of the 16 internal mDSL modems with the option of choosing the
Circuit ID, the Desired State, and the Test Mode Selection.
Clicking on the

figure 18).
Figure 18. mDSL Port Configuration window
Introduction 61
9 • mDSL Port Configuration mDSL DACS Administrators’ Reference Guide
The mDSL main window (see figure 18) displays the status of all mDSL ports.
The summary displays statistics for the mDSL ports:
Number of mDSL Available (numAvailMdsl) - The number of internal mDSL ports currently available to
•
the user. If your Model 3095 has 16 mDSL modems, the sum of the values in
and
Number of mDSL Failed will be 16. Otherwise, for an 8-modem model, the sum will equal 8. This
Number of mDSL Available
parameter is determined automatically when the mDSL modems are tested for availability or failure during
power up.
• Number of mDSL Failed (numFailMdsl) - The number of ports that have a hardware failure. If your Model
3095 has 16 mDSL modems, the sum of the values in
Failed
will be 16. Otherwise, for an 8-modem model, the sum will equal 8. This parameter is determined
Number of mDSL Available and Number of mDSL
automatically when the mDSL modems are tested for availability or failure during power up.
Number of mDSL Activated (numTurnOnMdsl) - The number of ports (internal mDSL modems) that are
•
currently active and ready to connect to a remote CPE mDSL modem. To be activated, the user has commanded it to connect. This includes the number of modems connected.
•
Number of mDSL Connected (numConnectMdsl) - The number of ports that are currently connected to the
CPE's remote mDSL modem. "Connected" means it is in dataSync mode and can pass data.
Number of mDSL Test Mode (numTestModeMdsl) - The number of mDSL modem ports in one of the test
•
modes.
Total Flap Count (flapCounterMdsl) - The number of times which a modem link has gone down and come
•
back up. An mDSL modem is considered to have gone down if it has left dataSync mode and gone into
dataLink mode or lower. When it returns to dataSync mode, the modem link is back up. This count is set to
zero when the 3095 is powered up or when the user resets it on each mDSL Port Information Page. This
page is found by clicking on the Port Number in the table on this web page.
•
Number of Unconnected Activated Ports (numPendingLinkMdsl) - Unconnected activated ports are ports
which are activated but not yet connected (that is, connected means being in dataSync mode). This is the
equal to (Number of mDSL Activated) - (Number of mDSL Connected).
•
Percentage Ports Connected (%) (percentLinkMdsl) - The percentage of the number of ports in the dataSync
mode. The formula equals [(Number of mDSL Connected)/(Number of mDSL Activated) * 100].
Action buttons
The Action buttons perform the following actions:
• Activate all Available Ports activates the available mDSL ports. See
Number of mDSL Available at the
top of the Web page for the quantity available.
• Deactivate All Ports deactivates the available and failed ports.
• Activate Ports 1 - 4
and Activate Ports 5 - 8, Activate Ports 9 - 12, Activate Ports 13 - 16 will activate
the mDSL modems in the appropriate group.
• If your Model 3095 has 8 modems, only Activate Ports 1 - 4 and Activate Ports 5 - 8 buttons will dis-
play.
62 mDSL Port Configuration window
mDSL DACS Administrators’ Reference Guide 9 • mDSL Port Configuration
• The Submit Query button submits changes made in the Circuit ID, the Desired State, and Test Mode
Selection columns for 16 mDSL ports. There are two Submit Query buttons, one on top of the table, the
other on the bottom, both of which function identically.
• As with all Submit Query entries, the configuration changes are saved in volatile dynamic memory. After
clicking on Submit Query, the changes take effect immediately. Only by going to the
3095 Configuration Menu and clicking on Save Current Configuration will the configuration be stored in
HOME page in the
non-volatile Flash memory.
mDSL Port Table
The table shows the characteristics for each of the 16 internal mDSL modems. By clicking on the Port number, you can examine other statistics and configure more parameters. (See “mDSL Port Configuration Page
window” on page 81). For each port number, the table shows the user-defined
the modem, the
Desired State of the modem, and the internal connection of each B-channel; which are
Circuit ID, the Current State of
described in the following sections.
Port Number (mdslconfigID)
This identifies each of the 16 mDSL modems uniquely. It is a link to the “mDSL Port Information window”
on page 68 which displays more options and statistics for that mDSL port.
Circuit ID (userIDMdsl)
User-defined field for assigning a name to each mDSL port. The name can consist of up to 40 ASCII
characters.

• idle(0)—disconnected
• dataLink(1)—indicates that the "DSP" modules in the mDSL modems have established communication
• handshaking(16)—setting up configuration parameters between the two mDSL modems
• training(24)—analyzing the line characteristics for maximum performance
• testmode(32)—indicates that the mDSL modem is in on of the test modes
• initializing(35)
• localLineLoop(130)—this is loopback LL
• localDigitalLoop(131)—this is loopback LDL
• dataMode-RDL(135)—this is loopback RDL

transfer of data can occur
• hardwareFailure(200)—indicates that this particular mDSL modem in the 3095 has failed and is not oper-
ational
Desired State (userDesireMdsl)
The following actions choose the desired mode of operation for the mDSL port.:
• disconnect(0)—puts the mDSL modem in the idle state
64 mDSL Port Configuration window
mDSL DACS Administrators’ Reference Guide 9 • mDSL Port Configuration
• connect(1)—indicates that the mDSL modem is being activated and is trying to enter the connected state,
which is dataSync mode
• reset(2)—when this action occurs, the modem hardware is reset to the idle state, after which it returns to
the state preceeding the reset action. For example, if the modem is in the disconnect(0) state, a reset will
complete a hardware reset and then return to the disconnect(0) state. Otherwise, if the modem is attempting to connect or is in the connect (dataSync) state, the reset action will do the hardware reset, subsequently
returning to the connect state.
• abortAction(15)—this action immediately aborts the current state and returns to the disconnect(0) mode.
The Test Mode Selection (testModeMdsl)
This option is for selecting an optional test mode for the mDSL modem port. There following modes are available:
Note The loopback tests are described in detail in section “Loopback tests”
on page 65. The remaining laboratory tests (download, drivers, and
spectrum) are covered in section “Laboratory tests” on page 66.
• ModeOff(0)—the mDSL modem is not in test mode
• localLoopback(3)—the mDSL modem is in local digital loopback (LDL) test mode (see figure 19)
• remoteLoopback(6)—the mDSL modem is in remote digital loopback (RDL) test mode
• lineLoopback(9)—the mDSL modem is in line loopback (LL) test mode
Loopback tests
To understand the path for loopback tests, it is better to consider the fundamental architecture of the mDSL
modems. As shown in figure 19, there are three blocks named framer, digital signal processor (DSP), and analog
front end (AFE).
The AFE provides the 2-wire (single twisted-pair) line connection to the remote modem.
The following loopback tests are looped back in one of these three blocks.
Note The remote end-user cannot initiate a remote digital loopback from
the modem, thereby preventing the remote user from controlling features of the Model 3095..
The local (digital) loopback's path (
The remote (digital) loopback (
The local line loopback (
lineLoopoBack(9)) loops the data originating from the CPE remote modem through
localLoopback(3)) is routed through the DSP.
remoteLoopback(6)) is routed through the DSP of the CPE remote modem.
the AFE of the 3095's internal modem.
Except for the local loopback initiated by the CPE remote modem, all loopback tests are initiated and controlled by the 3095 DACS.
mDSL Port Configuration window 65
9 • mDSL Port Configuration mDSL DACS Administrators’ Reference Guide
When the end-user at the CPE remote modem location initiates a local loopback test on the modem, there are
two possible paths:
• If there is a data connection between the remote modem and the 3095's internal modem, the path is looped
back through the framer.
• If there is no modem line connection, the loopback occurs through the DSP.
• Laboratory tests
Test Modes
downloadTest(12), driversTest(13), and spectrumTest(14) are engineering laboratory tests. They
are not intended for use outside of the factory.
DTE Rate (dteRateMdsl)
Displays the currently configured DTE rate of the mDSL modem link. The DTE rates are:
• dteRateNone(0) • dteRate832(15)—832 kbps • dteRate1664(29)—1664 kbps
• dteRate64(3)—64 kbps • dteRate896(16)—896 kbps • dteRate1728(30)—1728 kbps

Clock Mode (clockModeMdsl)
Displays the clocking mode of the internal mDSL modem. One of the following modes will be displayed:
• independent-receiveClock(0)
• systemClocking-receiveClock(1)
• cpeClocking-intClock(2)
• cpeClocking-extClock(3)
• sysemClocking-extClock(4)
• systemClocking-intClock(5)
To understand the nomenclature of the Clock Mode options, notice that the dash distinguishes between the
local clock source for the selected mDSL modem within the 3095 and the clock source for the CPE mDSL
modem. (For example, in systemClocking-receiveClock(1), the 3095’s mDSL modem is deriving its transmit
66 mDSL Port Configuration window
mDSL DACS Administrators’ Reference Guide 9 • mDSL Port Configuration
clock from the time-slot exchanger (hence, systemClocking.). The CPE mDSL modem uses the receive recovered clock for its transmit clock source.)
The following are clock sources for the 3095’s internal mDSL modems:
• Internal—clock source is provided from the 3095’s internal oscillator and is only used with the V.35 serial
egress card.
• External—clock is derived from the mDSL time slot exchangers
• Receive—the clock source is recovered from the DSL line.
When the 3095 is equipped with a T1/E1 egress card, the clock mode would be one of the following:
• ext-receiveClock(1)
• ext-extClock(4)
• ext-intClock(5)
The three options, int-receiveClock(0), receive-intClock(2), and receive-extClock(3) cannot be used with the
Model 3095’s mDSL modems, onlly with the V.35 serial egress module.

mDSL DACS Administrators’ Reference Guide 9 • mDSL Port Configuration
• hardwareFailure(200)—indicates that this particular mDSL modem in the 3095 has failed and is not oper-
ational
The following describes the normal sequence of states an mDSL modem goes through during the connection
process:
1. idle
2. handshaking
3. training
4. dataLink
5. dataSync
The modem link is considered to be “connected” for data transmission only after dataSync(160) state is established.
Line (S/N ratio) Quality (dB) (lineQualityMdsl)
This item displays the signal quality of the mDSL link. The signal-to-noise (S/N) ratio is measured in dB. Each
mDSL line rate has a minimum Signal Quality (SQ) that will support a BER of 1e-7. Table 4 shows the
approximate average SQ for each line rate with noise (self-NEXT) that would produce a BER of 1e-7.
Without noise the range may increase.

Framer Mode (Local Status) (framerModeMdsl)
The Framer can function in two different states:
• framerModeG704(0)—Used if the T1/E1 Egress Card or V.35 serial Egress card is being used at data rates
less than or equal to 2.048 Mbps.
• framerModeNormal(1)—Used if the V.35 serial egress card is operating at a data rate greater than 2.048
Mbps.
This setting is configured automatically by the DACS.
Framer Mode (Remote Status) (remoteframerModeMdsl)
The Model 3095 will read the remote modem’s Framer Mode. Normally you will not configure this parameter
from the 3095. The states for the remote modem are:
• framerModeG704(1)—Used for remote modems having the /K interface.
• framerModeNormal(3)—Used for remote modems having the /C (V.35), /D (X.21), or /I (Ethernet) inter-
faces.
• notavailable(50)—This state appears if there is no DSL link or before the DSL link reaches the dataSync
state.

mDSL DACS Administrators’ Reference Guide 9 • mDSL Port Configuration
CO/CP Mode (Local Status) (cocpModeMdsl)
The following options are available:
• coMode(0)
• cpMode(1)
CO refers to the Central Office or central site where the 3095 is located. CP is the customer’s premises. For the
mDSL modems to function, one modem must be in CO and the other in CP mode. Normally the 3095’s
internal modem is configured for CO mode. Subsequently the remote CPE modem will be configured for CP
mode.
CO/CP Mode (Remote Status) (remoteCOCPMdsl)
Applicable only when the remote modem is a Model 1088/K or 1095E1/K. The following options are available
for the remote CPE mDSL modem:
• forcetoCP(0)—When forcetoCP(0) appears, either the 3095’s administrator sent the configuration option
to the remote modem to force it to be CP, or the remote modem was independently preconfigured to CP
mode.
• normal(1)—indicates that the remote modem’s CO/CP parameter was automatically configured by the
3095. In other words, the CO/CP mode is determined by which clock mode the CPE modem is in.
• notavailable(50)
Clock Mode (Local Status) (clockModeMdsl)
This gives the source of the transmit clocks for both the 3095’s internal modem as well as the remote CPE
modem. The available options are:
• independent-receiveClock(0)
• systemClocking-receiveClock(1)
• cpeClocking-intClock(2)
• cpeClocking-extClock(3)
• sysemClocking-extClock(4)
• systemClocking-intClock(5)
To understand the nomenclature of the Clock Mode options, notice that the dash distinguishes between the
local clock source for the selected mDSL modem within the 3095 and the clock source for the CPE mDSL
modem. (For example, in ext-receiveClock(1), the 3095’s mDSL modem is deriving its transmit clock from the
time-slot exchanger (hence, ext.). The CPE mDSL modem uses the receive recovered clock for its transmit
clock source.)
Clock Mode (Remote Status) (remoteClockMdsl)
The following options are available for the transmit clock source in the remote mDSL modem:
• intClk(0)
• extClk(1)
mDSL Port Information window 75
9 • mDSL Port Configuration mDSL DACS Administrators’ Reference Guide
• receiveClk(2)
• notavailable(50)
The remote modem’s internal oscillator is indicated by intClk(0).
If extClk(1), the remote modem is deriving its clock from the DTE side of the modem connection.
On the other hand, receiveClk(2) uses the recovered receive clock from the modem line for use as receive clock
and transmit clock. Consequently, the transmit and receive clocks are the same clock.
Unit User ID (Local Status) (userIDMdsl)
This is the Circuit ID on the main mDSL Port Configuration window.
Unit User ID (Remote Status) (remoteUserIDMdsl)
The unit user ID for the remote modem can be configured after the mDSL link is in the dataSync state. Maximum length is 8 octets (characters).
Remote Unit Software Version (Remote Status) (remoteSoftwareVersionMdsl)
Displays the software version which is currently in the remote modem.

This parameter displays whether a Local Loopback may be initiated or not from the DTE interface. The
parameters are:
• enabled(0)
• disabled(1)
• notavailable(50).
• If enabled(0), the remote modem is able to initiate a local Loopback via the DTE interface. If disabled(1), it
cannot.
The notavailable(50) parameter normally appears when the 3095’s modem is in the idle state or if there is no
line connection between the modems.
Remote Unit TX Edge (Remote Status) (remoteTXEdgeMdsl)
The sampling point of Transmit Data is controlled here. The options are:
• normal(0)
• inverted(1)

Current Seconds (currentSecondMdsl)
The number of seconds which have passed since the beginning of the current 15-minute interval.
15 Minute Intervals Since Activation (interval15minMdsl)
The number of completed 15-minute intervals which have occurred since the port has been activated. It does
not include the current 15-minute interval. The maximum number of 15-minute intervals is 96 which covers a
24-hour period. This data can be used for monitoring the operation of a port within one 24-hour period. The
following parameters are defined over one 15-minute interval.
Errored Seconds (ES) (errSecondMdsl)
An errored second occurs when either (1) the CRC does not match the calculated CRC or (2) when the line is
linked up but lacking synchronization. Whether 1 error up to 81 errors occur within a second, it will still be 1
errored second.
Severely Errored Seconds (SES) (sevErrSecondMdsl)
A severely errored second is defined for one mDSL line as a second containing more than 82 CRC errors. The
SES counter will not be incremented when the box is incrementing the Unavailable Seconds count.
Unavailable Seconds (UAS) (unavailableSecMdsl)
Unavailable seconds is an indication of the amount of time that an mDSL port is activated but not available for
data transmission. The UAS counter is incremented under the following criteria.
• The port must be activated.
• Once the port is activated, the UAS counter will be incremented if the ports loses sync or does not enter
synchronization with the far end of the link.
• Once the port gains link status, the 3095 begins looking for ES and SES.
• Upon receiving 10 consecutive SES or a line down indication, the 3095 will begin reporting UAS. The
3095 will not increment ES or SES during the UAS count.
• The UAS count will stop when 10 consecutive seconds without an SES is detected.
History…
Clicking on the History hyperlink displays the History of Near End Performance window (figure 22). It displays the cumulative statistics for each of the 15-minute intervals. The most recent 15-minute interval is numbered 1. The maximum number of 15-minute intervals is 96.

Figure 22. History of Near End Performance window
The history page collects and records the error history of the port. Interval 1 is the history of the most recent,
completed 15-minute interval. The length of each interval is 15 minutes. and records how many ES, SES, and
UAS have occurred in the 15 minute intervals. The maximum number of intervals is 96 which is one 24-hour
time period. (15 minutes x 96 = 24 hours). The history page always records the last 24 hours error performance
of the port. Information older than 24 hours will not be shown and will be erased.
mDSL Port x (mdslIntervalIndex)
In this example of “mDSL Port x” the number of the port may range from 1 to 16. This number is the index
value which identifies the referred mDSL modem port.
Interval (mdslIntervalNumber)
This refers to a completed 15 minute interval. This number may range from 1 to 96, where 1 is the most
recently completed 15 minute interval and 96 is the least recently completed 15 minute interval. The maximum of 96 intervals equals the historical data for the last 24 hours of operation.
Errored Seconds (ES) (historyESMdsl)
Indicates the number of errored seconds. An errored second occurs when either (1) the CRC does not match
the calculated CRC or (2) when the line is linked up but lacking synchronization. Whether 1 error or up to
159 errors occur within a second, it will still be 1 errored second.
Severely Errored Seconds (SES) (historySESMdsl)
Indicates the number of severely errored seconds. A severely errored second is defined for one mDSL line as a
second containing more than 160 CRC errors. The SES counter will not be incremented when the box is
incrementing the Unavailable Seconds count.
Unavailable Seconds (UAS) (historyUASMdsl)
Displays the number of seconds that the modem line was unavailable. Unavailable seconds is an indication of
the amount of time that an mDSL port is activated but not available for data transmission. The UAS counter is
incremented under the following criteria.
• The port must be activated.
• Once the port is activated and a link-up timer has expired, the UAS counter will be incremented if the ports
loses sync or does not enter synchronization with the far end of the link.
• Once the port gains link status, the 3095 begins looking for ES and SES.

Line Quality (historyLineQualityMdsl)
Displays the signal quality of the mDSL link for each of the 15 minute intervals. It is measured as the S/N ratio
in dB. Each mDSL line rate has a minimum Signal Quality (SQ) which will support a BER of 1e-7. Table 4 on
page 71 shows the approximate average SQ for each line rate with noise (self-NEXT) that would produce a

SQE Test Errors (dot3StatsSQETestErrors)
A count of times that the SQE TEST ERROR message is generated by the PLS sublayer. The SQE TEST
ERROR message is defined in section 7.2.2.2.4 of ANSI/IEEE 802.3-1985 and its generation is described in
section 7.2.4.6 of the same document."
Deferred Transmissions (dot3StatsDeferredTransmissions)
The number of times for which the first transmission attempt is delayed because the medium is busy. This
number does not include frames involved in collisions.
Late Collisions (dot3StatsLateCollisions)
The number of times that a collision is detected later than 512 bit-times into the transmission of a packet. Five
hundred and twelve bit-times corresponds to 51.2 microseconds on a 10 Mbps system. A (late) collision
included in a count of late collisions is also considered as a (generic) collision for purposes of other collisionrelated statistics.
Excessive Collisions (dot3StatsExcessiveCollisions)
The number of frames in which transmission failed due to excessive collisions.
Other Errors (dot3StatsInternalMacTransmitErrors)
The number of frames for which transmission fails due to an internal MAC sublayer transmit error. A frame is
only counted if it is not counted by the corresponding instance of either the dot3StatsLateCollisions object,
the dot3StatsExcessiveCollisions object, or the dot3StatsCarrierSenseErrors object. The precise meaning of the
count represented by an instance of this object is implementation-specific. In particular, an instance of this
object may represent a count of transmission errors on a particular interface that are not otherwise counted.
Carrier Sense Errors (dot3StatsCarrierSenseErrors)
The number of times that the carrier sense condition was lost or never asserted when attempting to transmit a
frame. The is incremented at most once per transmission attempt, even if the carrier sense condition fluctuates
during a transmission attempt."
Received Frames Too Long (dot3StatsFrameTooLongs)
The number of frames received that exceed the maximum permitted frame size. The count is incremented
when the frameTooLong status is returned by the MAC service to the LLC (or other MAC user). Received
frames for which multiple error conditions obtain are, according to the conventions of IEEE 802.3 Layer Management, counted exclusively according to the error status presented to the LLC."

Other Received Errors (dot3StatsInternalMacReceiveErrors)
The number of frames in which reception fails due to an internal MAC sublayer receive error. A frame is only
counted if it is not counted by either the dot3StatsFrameTooLongs object, the dot3StatsAlignmentErrors
object, or the dot3StatsFCSErrors object. The precise meaning of the count represented by an instance of this

Introduction
The DACS software provides an IP filtering system that enables you to set up security for the internal management system.
Each filter is a defined list of parameters based upon attributes in the IP, TCP, and UDP headers. There are two
major steps to filter creation: first defining the filter, then applying it to a user connection. The same filter can
be shared by several users.
The DACS enables 20 separate filters to be defined, of which up to 10 can be used during a single user connection. Since the IP connections in the 3095 are only for the superuser and the monitor user, these will be the
only two users. The application of the filters is done on the Filter IP main web page.
Click on
Filter IP under the Configuration Menu to display the FIlter IP main window (see figure 25).
Figure 25. Filter IP main window
Defining a filter
This section gives a brief summary on defining a filter. For a complete discussion with filter examples, see the
final section.
To define a new filter, enter an ID number (filterIpId) and a name (filterIpName), then click on the Submit
Query button to submit the request. The ID number and name must not already exist in the IP FILTER list,
and the number must be an integer between 1 and 20. To delete a filter, enter just the ID number without a
name and click on the Submit Query button.
Note Block filters take priority, therefore any applied and matching block
filters will drop the packet. Next, pass filters are examined, if PASS filters have been defined, then at least one of them must match or else
the packet will be dropped. After the block and pass filters are examined, the WRAP filter, if it exists, will be applied.

The configurable filter parameters are :
• Name (filterIpName)
• Direction (filterIpDirection)
• Action (filterIpAction)
• Source IP (filterIpSourceIp)
• Source IP Mask (filterIpSourceMask)
• Destination IP (filterIpDestinationIp)

Note Any changes to a filter take effect immediately upon clicking Submit
Query. This can aid in troubleshooting a filter profile while the user
is online.
Defining a filter 91
11 • Filter IP mDSL DACS Administrators’ Reference Guide
The following sections provide detailed descriptions of the configurable filter IP parameters.
Name (filterIpName)
This is the name of the filter
Direction (filterIpDirection)
Specifies the direction of the filter (that is, whether it applies to data packets inbound or outbound from the
DACS). The filter only applies to the Superuser and the Monitor Users through the Ethernet interface. (Since
the mDSL modem and WAN connections function as a transparent pipe, neither of the two users can utilize
these interfaces, only the Ethernet interface.) The following options are available:
• inactive(0)—Disables filter operation
• inbound(1)—Relates to packets coming into the DACS
• outbound(2)—Relates to packets leaving the DACS
• both(3)—Specifies both inbound and outbound operation
Action (filterIpAction)
Specifies the action to effect the packet. The action decides whether to block or pass the packet. The following
options are available:
• pass(0)—If pass is selected, checking will continue on to other filters until either a match occurs, a block
occurs, or there are no more filters remaining to check.
Note If there are any applied PASS filters, then at least one of them must
match or the packet will be dropped.
• block(1)—If a filter has block set and the filter matches the block, the packet is discarded and no further
processing is done.
• wrap(2)—All packets received on the specified link will be encapsulated in an extra IP header as defined in
RFC2003. The destination IP address of the wrapper is given by the destination IP setting in the filter. The
source IP address of the wrapper is the ethernet address of the DACS.
All wrap filters are inbound only.
Source IP (filterIpSourceIp)
This is the Source IP address in the IP header, it is used when comparing a packet’s source address.
Source IP Mask (filterIpSourceMask)
This is the Source IP Mask (filterIpSourceMask) used when comparing a packet’s source address. Bit positions
that are set to 1 will be compared and 0’s will be ignored. Thus, a setting of 0.0.0.0 will have the effect of disabling source IP address comparison.
Destination IP (filterIpDestinationIp)
This is the destination IP address in the IP header used when comparing a packet’s destination address.
92 Defining a filter
mDSL DACS Administrators’ Reference Guide 11 • Filter IP
Destination Mask (filterIpDestinationMask)
This is the destination mask used when comparing a packet’s destination address. Bit positions that are set to 1
will be compared and 0’s will be ignored. Thus, a setting of 0.0.0.0 will have the effect of disabling destination
IP address comparison.
Source Port (FilterIpSourcePort)
Specifies the source port number (TCP or UDP) that the access server DACS compares. The source port
Action (see Action (filterIpSourcePortCmp) next) action will determines how the source port is treated.
whether the source port in the IP packet is not compared, equal, less than, or greater than the Source Port designated in the filter.
Action (filterIpSourcePortCmp)
Specifies the Action (filterIpSourcePortCmp) that the DACS compares. The source port action determines
whether the source port in the IP packet is not compared, equal, less than, or greater than the Source Port designated in the filter.
• noCompare(0) – No Comparison to the source port in the IP packet.
• equal(1)—The port in the source IP packet is the same
• lessThan(2)—The port in the source IP packet is less than
• greaterThan(3)—The port in the source IP packet is greater than
Destination Port (filterIpDestinationPort)
Specifies the destination port number which the DACS compares. The destination action functions similarly
to the Source Port and its Action defined above.
Action (filterIpDestinationPortCmp)
Specifies the action (TCP or UDP) which the DACS compares. The destination action will determine how the
destination port is treated.
• noCompare(0)—No Comparison to the destination port in the IP packet.
• equal(1)—The port in the destination IP packet Is the same
• lessThan(2)—The port in the destination IP packet is less than
• greaterThan(3)—The port in the destination IP packet is greater than
Protocol (filterIpProtocol)
Specifies the IP Protocol number to use for filtering. Some examples of protocol numbers are 1 for ICMP; 6 for
TCP; and 17 for UDP. A list of protocol numbers can be found in RFC 1340. A setting of 0 disables processing based on protocol number.
TCP Established (filterIpTcpEstablished)
Specifies whether the filter should match only those packets which indicate in the TCP header flags that the
connection is established. The following choices are available:
• anyPackets(0)—Applies the filter to all packets
• onlyEstablishedConnections(1)—Only applies the filter to established TCP connections

Introduction
When networking problems or undesirable conditions occur, the ICMP protocol is used for communicating
control or error information plus testing. The statistics listed on the DACS ICMP window (see figure 27) comprise those contained in RFC 792—Internet Control Message Protocol (ICMP). Implementation of the ICMP
group is mandatory for all TCP/IP networks. RFC 1312—ICMP Group of MIB-II Variables—provides the
definitions of these variables. It is important to remember that any RFC can be superseded by a newer.
Figure 27. ICMP window
Click on ICMP under the Configuration Menu to monitor DACS ICMP statistics.
Block ICMP redirects (boxBlockIcmpRedirects)
The two options for “Block ICMP Redirects” either allow the reception of ICMP Redirect messages [allowRedirects(0)] or block the reception of ICMP Redirect messages [stopRedirects(1)]. The recommended configuration is to block the ICMP redirect messages because in some instances they could alter the routing table with
undesirable effects, which is considered a breach of security.
ICMP Receive/Send Messages window
The ICMP window displays the ICMP message counters. ICMP messages are displayed in the window as columns comprising two types of messages:
• Messages received by the DACS (InMibVariable)
• Messages sent by the DACS (OutMibVariable)
The numbers following the parameters can be a good source of what is happening on the network to point out
potential problems. Both gateways (routers) and hosts can send ICMP messages.
Total Received (icmpInMsgs)
The total number of ICMP messages which the 3095 Multiplexer has received. Note that this counter includes
all those counted by icmpInErrors (see “w/Errors (icmpInErrors, icmpOutErrors)” on page 99).
