Chapter 4 Alarms Chapter contents Introduction ..........................................................................................................................................................30 Displaying the alarms window ...............................................................................................................................30 Alarm Response Outputs ............................................................................................................................
4 • Alarms T1/E1 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. There are 83 alarms that can be configured by the system administrator to generate alerts based on the condition of the DACS.
T1/E1 DACS Administrators’ Reference Guide 4 • Alarms The T1/E1 DACS 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. 2.
4 • Alarms T1/E1 DACS Administrators’ Reference Guide 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 33. Relay Response 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.
T1/E1 DACS Administrators’ Reference Guide 4 • Alarms Alarm Time The Alarm Time column displays the number of seconds the alarm has been activated. Alarm Count The Alarm Count column indicates how many times the alarm has occurred and is useful for monitoring selfclearing alarms. Generate Alarm For testing purposes, clicking the Generate Alarm button next to each alarm name will cause that alarm condition to be activated.
4 • Alarms T1/E1 DACS Administrators’ Reference Guide • 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 when a power supply fails.
T1/E1 DACS Administrators’ Reference Guide 4 • Alarms Temperature Threshold 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 12) displays a table listing each individual alarm.
4 • Alarms T1/E1 DACS Administrators’ Reference Guide • MinorSelfClearing(3)—Generate a minor alarm that automatically clears after a fixed period of time. If the alarm condition has not ceased, the alarm will be automatically cleared, but another alarm will be immediately generated. 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.

Chapter 8 Filter IP Chapter contents Introduction ..........................................................................................................................................................50 Defining a filter .....................................................................................................................................................50 Name (filterIpName) .................................................................................................................
8 • Filter IP T1/E1 DACS Administrators’ Reference Guide 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.
T1/E1 DACS Administrators’ Reference Guide 8 • Filter IP After entering an ID number and name, click on the name of the filter to display the filter parameters window (see figure 18). Figure 18.
8 • Filter IP T1/E1 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.
T1/E1 DACS Administrators’ Reference Guide 8 • 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.

Chapter 9 ICMP Chapter contents Introduction ..........................................................................................................................................................56 Block ICMP redirects (boxBLockIcmpRedirects) ..................................................................................................56 ICMP Receive/Send Messages window..................................................................................................................
9 • ICMP T1/E1 DACS Administrators’ Reference Guide 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 19) 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.
T1/E1 DACS Administrators’ Reference Guide 9 • ICMP Total Sent [imcpOutMsgs] Similar to icmpInMsgs, Total Sent represents the total number of ICMP messages which the 2604 has attempted to send. This variable includes all ICMP messages counted by icmpOutErrors (see “wo/Errors [icmpOutErrors]”). w/Errors (icmpInErrors, icmpOutErrors) The number of ICMP messages which the Model 2604 received/sent but having ICMP-specific errors (for example, bad ICMP checksums, bad length, or non-routable errors).
9 • ICMP T1/E1 DACS Administrators’ Reference Guide ICMP source quench message back to the sending device. A host may send this messages if packets arrive too fast to be processed or if there is network congestion. The source quench message is a request to reduce the rate at which the source is sending traffic. If the DACS receives a source quench, it will wait for acknowledgement of all outstanding packets before sending more packets to the remote destination.
