FEDERAL COMMUNICATIONS COMMISSION RADIO
FREQUENCY INTERFERENCE STATEMENT
This equipment has been tested and found to comply with the limits
for a Class A digital device, pursuant to Part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against
harmful interference in a commercial environment. This equipment
generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio frequencies. Operation of this equipment in a
residential area is likely to cause harmful interference in which case
the user will be required to correct the interference at his own expense.
Shielded cables must be used with this unit to ensure
compliance with Class A FCC limits.
Changes or modifications to this unit not expressly approved by ADTRAN will void the user's authority to
operate the equipment.
CANADIAN EMISSIONS REQUIREMENTS
This digital apparatus does not exceed the Class A limits for radio
noise emissions from digital apparatus as set out in the interferencecausing equipment standard entitled "Digital Apparatus," ICES-003 of
the Department of Communications.
Cet appareil nuerique respecte les limites de bruits radioelectriques
applicables aux appareils numeriques de Class A prescrites dans la
norme sur le materiel brouilleur: "Appareils Numeriques," NMB-003
edictee par le ministre des Communications.
viii
CANADIAN EQUIPMENT LIMITATIONS
Notice: The Canadian Industry and Science Canada label identifies
certified equipment. This certification means that the equipment
meets certain telecommunications network protective, operational,
and safety requirements. The Department does not guarantee the
equipment will operate to the user’s satisfaction.
Before installing this equipment, ensure that it is permissible to be
connected to the facilities of the local telecommunications company.
The equipment must also be installed using an acceptable method of
connection. In some cases, the company’s inside wiring associated
with a single-line individual service may be extended by means of a
certified connector assembly (telephone extension cord). Compliance
with the above conditions may not prevent degradation of service in
some situations.
Repairs to certified equipment should be made by an authorized Canadian maintenance facility designated by the supplier. Any repairs or
alterations made by the user to this equipment, or equipment malfunctions, may give the telecommunications company cause to request the user to disconnect the equipment.
Users should ensure for their own protection that the electrical ground
connections of the power utility, telephone lines, and internal metallic
water pipe system, if present, are connected together. This precaution
may be particularly important in rural areas.
Users should not attempt to make such connections
themselves, but should contact the appropriate electric
inspection authority, or an electrician, as appropriate.
The Load Number (LN) assigned to each terminal device denotes the
percentage of the total load to be connected to a telephone loop which
is used by the device, to prevent overloading. The termination on a
loop may consist of any combination of devices subject only to the requirement that the total of the Load Numbers of all devices does not
exceed 100.

Introduction
PRODUCT OVERVIEW
The ADTRAN IQ Probe provides the visibility and control needed for both
the physical and logical connections made in frame relay networks. The IQ
Probe provides logical layer monitoring and management for frame relay.
Each permanent virtual circuit (PVC) accessed through an IQ Probe is
managed end-to-end as if it were a leased line connection. Real-time statistics on throughput, bandwidth utilization, availability, bursting, congestion, and network delay are collected and stored. The statistics are
viewable through the IQ Probe using the front panel, the VT-100 interface,
or the Frame IQ MIB (management information base). This information
can be gathered by management systems via SNMP (simple network management protocol) and used to monitor network health and perform longterm network planning.
The unit's embedded SNMP agent provides complete SNMP access to the
unit. SNMP access is available through the DTE or DCE port or through
an integral SLIP (serial line internet protocol) or PPP (point-to-point protocol) async port. The IQ Probe also provides an integrated 10BaseT ethernet access for SNMP.
The following are features of the IQ Probe:
•
Complete and comprehensive frame relay monitoring
•
Real-time measurement of bandwidth utilization, committed
information rates (CIRs), and excess burst rates on each PVC
•
True non-intrusive, in-band transmission of statistics
•
Embedded SNMP and Telnet through the DTE, DCE, SLIP/PPP, or
integrated 10BaseT ethernet port

UNDERSTANDING FRAME RELAY
Frame relay is a wide area network (WAN) service designed to minimize
physical connections. This is accomplished by using virtual connections
within the frame relay cloud and accessing these virtual circuits with normally one physical connection at each location to the frame relay service.
Virtual circuits are addressed using header information at the beginning
of each frame. These frames are formatted by a device such as a router or
FRAD (frame relay access device) and monitored by the IQ Probe.
ANSI (American National Standards Institute) standards describe how
each frame must be constructed to provide interoperability between CPE
equipment and frame relay switching equipment. Each frame must contain a header, at least one byte of information data, two bytes of CRC16,
and a trailing flag 0x7E.
This header information contains a virtual circuit address known as a
DLCI (data link connection identifier). The header information also contains bits used for network congestion control.
Frame relay virtual circuits may be defined as permanent (PVC) or
switched (SVC). PVCs have the same DLCI for a given path each time a
user protocol session is established. The network service provider assigns

these DLCIs at subscription time. SVCs, on the other hand, have DLCIs dynamically assigned each time a user protocol session is established. The
CPE equipment must request a call and the DLCI is assigned by the network switching equipment. This DLCI is valid until the call is disconnected and may be assigned a different value each time a call is requested.
SNMP MANAGEMENT
SNMP management capability is provided in-band with support for RFC
1315 (frame relay DTE MIB), RFC 1213 (MIB II), and ADTRAN Enterprise
MIB. MIB files are available from ADTRAN in the support section of the
ADTRAN web page at www.adtran.com. Telnet capability is also supported. For non-TCP/IP environments, VT-100 and front panel operation
are supported.
The IQ Probe's embedded SNMP feature allows the unit to be accessed
and controlled by a network manager in-band at the DTE or DCE interface, out-of-band at the control port via SLIP or async PPP, or using a LAN
connection.
The term SNMP broadly refers to the message protocols used to exchange
information between the network and the managed devices, as well as to
the structure of network management data bases. The three basic components of SNMP follow:
Network Manager
Control program that collects, controls, and presents data pertinent to the
operation or management of the network devices. It resides on a network
management station.
Agent
Control program that resides in each connected network device. This program responds to queries and commands from the network manager and
returns requested information or invokes configuration changes initiated

Chapter 1. Introduction
TELNET
Telnet provides a password-protected, remote log-in facility to the IQ
Probe. Telnet allows a user on a network manager to control the IQ Probe
through the terminal menus.
DIAL BACKUP OPERATION
The IQ Probe dial backup (DBU) option cards provide single or multiple
site backup. The IQ Probe can be configured to originate a call based on
physical layer conditions (i.e., port failures) and/or PVC outages. Once
the criteria are met, the IQ Probe establishes a call to the configured
phone number and the connection is used to carry traffic for the PVC(s)
configured for dial backup operation.
In the case of PVC outages (not physical layer port failure), the IQ Probe's
two-port design allows the IQ Probe receiving the call to continue to use
the T1 frame relay circuit for PVCs that are not affected by the outage,
while using the DBU interface for PVCs that are inactive due to the
outage. An IQ Probe with multiple PVCs to multiple sites can also
originate a call to one site during an outage and restore connection for
PVCs to that destination.
The IQ Probe's unique DBU cards are field-installable by the customer. See
Installation on page 2-1 for information on installing DBU cards. The DBU
cards are compatible with other ADTRAN products supporting DBU. The
backup options are described in the following section, Interface Card Options. Contact the local telco provider to determine which services are
available in your area. See Applications on page 4-1 for more information,
including an example of a dial backup application.

Applications
This chapter provides examples of some common IQ Probe management
options as well as an example of a dial backup application. The management application examples include VT-100 management, out-of-band
SNMP/Telnet management, and in-band PVC SNMP/Telnet management. Descriptions and configuration tips for these options are provided
in the sections that follow.
The application drawings in this chapter show routers as the
frame relay device. The frame relay device could be any device
with frame relay capabilities. However, to use in-band
management, the management DLCI must be RFC 1490
encapsulated IP traffic.
MANAGEMENT APPLICATIONS
One of the main advantages of the IQ Probe is management flexibility. The
IQ Probe front panel interface provides complete configuration capabilities and viewing of key frame relay statistics information. Other management options described in this chapter provide configuration and
diagnostics capabilities as well as all-inclusive statistics information.
Local VT-100 Terminal Management
Connect a VT-100 terminal to the IQ Probe control port. This interface provides full-screen configuration and all-inclusive statistics access. VT-100
management also allows for remote configuration. Through this port, a remotely located ADTRAN IQ device is fully accessible for configuration,
diagnostics, and statistics viewing. Figure 4-1 on page 4-2 gives an example of a VT-100 application.

Out-of-Band Management
This management option (shown in Figure 4-2) is commonly used in situations where the customer is trying to reduce the amount of management
traffic flowing through the frame relay device. The IQ Probe can be managed though an established Telnet session or an SNMP-based network
manager like HP OpenView , IBM Netview , or SunNet Manager .
¨
¨
¨
The ADTRAN IQ Probe MIB is available in the support section
of the ADTRAN Web page at www.adtran.com.
SNMP and Telnet management is provided by one of the following interfaces:
•
A device (e.g., a router) running SLIP protocol. Connection is made
through the IQ Probe's control port.
•
A device (e.g., a router) running async PPP protocol. Connection is
made through the IQ Probe's control port.
•
A LAN. Connection is made through the 10BaseT ethernet interface.

traps. This selection is found under TRAP MGR OPTIONS in the SYSTEM portion of the CONFIGURATION menu.
Trap Manager Port
Enter the IQ Probe port used to transmit traps to the SNMP manager. This
selection is found under TRAP MGR OPTIONS in the SYSTEM portion of the
C ONFIGURATION menu.
You may assign up to five possible trap destinations in the TRAP
MGR OPTIONS table.
In-Band Management
The ADTRAN IQ Probe supports three modes of in-band management using the frame relay structure of PVCs. These modes are local
(see Figure 4-3 on page 4-6), shared (see Figure 4-4 on page 4-8), and dedicated PVC management (see Figure 4-5 on page 4-10). All three types
support complete SNMP management as well as Telnet capabilities.
All PVC-based in-band management traffic must be
noncompressed IP and use RFC 1490 encapsulation.
Local PVC Management
Local PVC management refers to a PVC created between the IQ Probe and
the frame relay router on the DTE interface of the IQ Probe. This type of
management is ideal when local management is needed but an ethernet
connection is not available. To support this type of management, all traffic
on the selected PVC must be RFC 1490 encapsulated, noncompressed IP
traffic.
The local PVC is sent out of the WAN serial port of the router as normal
WAN traffic and is terminated in the IQ Probe. Since the IQ Probe re61200214L1-20
IQ Probe User Manual
4-5
Chapter 4. Applications
sponds to Inverse ARP, it is not necessary to set up a static route in the
router. The router will discover the IP address automatically; however, it
will be necessary to set up a local PVC between the router and the IQ
Probe. Accomplish this by setting a value (between 16 and 1007) for the
DTE management DLCI on the IQ Probe to a value not used by the frame
relay network.
Local PVC management can be used at any location that has a router.
Therefore, remote sites can be accessed through the remote router. One
consideration when using local PVC management is that if the remote
router goes down, access to the remote IQ Probe is lost.

Shared PVC Management
Shared PVC management refers to a PVC that is used for normal data traffic between locations. The IQ Probe monitors this PVC for packets that
contain its IP address. When the IQ Probe detects a packet containing a
destination IP address that matches the IQ Probe IP address, the unit intercepts the packet and processes its TCP/IP information. To support this
type of management, all traffic on the selected PVC must be RFC 1490 encapsulated, noncompressed IP traffic.
61200214L1-20
IQ Probe User Manual
4-7
Chapter 4. Applications
Shared PVC management is used to manage remote ADTRAN IQ devices
without being dependent on services from the remote router. This usually
requires a static route at the host location.
By setting a local PVC management and shared PVC
management on the remote IQ Probe, its IP address can be
found through Inverse ARP.
Since the unit is set up for shared PVC management, all
management traffic will be intercepted prior to reaching the
remote router.

Dedicated PVC Management
Dedicated PVC management refers to the ability to have a PVC originated
from the network and terminated in the IQ Probe. This is an ideal configuration for third-party management. It isolates the customer’s data traffic
from network management traffic, and it also acts as a fire-wall that restricts management data to the IQ Probe. Dedicated PVC management is
also ideal when the user wants to guarantee access to a remote IQ Probe
regardless of the state of the remote LAN.

DIAL BACKUP APPLICATION
The IQ Probe dial backup (DBU) option cards provide single site backup.
The IQ Probe can be configured to originate a call based on physical layer
conditions (i.e., port failures) and/or PVC outages. Once the criteria are
met, the IQ Probe establishes a call to the configured phone number (see
Table 4-1 on page 4-12) and the connection is used to carry traffic for the
PVC(s) configured for DBU operation.
In the case of PVC outages (not physical layer port failure), the IQ Probe's
two-port design allows the IQ Probe receiving the call to continue to use
the T1 frame relay circuit for PVCs that are not affected by the outage.
This is done (without the attached DTE device's intervention) by
modifying the status of PVCs that are in DBU state to active when the
PVC status is given to the DTE.
An IQ Probe with multiple PVCs to multiple sites can also originate a call
to one site during an outage and restore connection for PVCs to that
destination. The other PVCs to other sites in this scenario will be inactive.
Information entered into the PVC CONFIGURATION table (see Table 4-2 on
page 4-13) marks PVCs for DBU operation. The key element in each entry
of the table is the DBU DLCI. For each PVC connecting two sites for DBU
operation, the DLCI field represents the PVC DLCI at the local UNI and
the DBU DLCI represents the PVC DLCI at the remote site UNI. The IQ
Probe uses this information in the outbound side to change the PVC DLCI
so the far end DTE device receives frames on the DBU PVC addressed in
the same manner as when the frame relay circuit is operational. For PVCs
not used for DBU operation, leave the DBU PHONE NUMBER field set for a
null entry. Enter a space character from the VT-100 terminal to create a
null entry for DBU PHONE NUMBER field.
Since the IQ Probe can only make one call at a time, only one
backup PVC will be active.
The DBU PHONE NUMBER is only required for the IQ Probe originating the
call.

during dial backup operation.
FECN/BECN
While in a congested state during dial backup operation, frames across the
DBU PVCs have FECN or BECN set depending on the direction. Frames
outbound to the network have FECN set, while frames inbound to the attached DTE device have BECN set. This method is useful if the attached
DTE devices can respond to congestion notification.
CTS Option
Set the CTS lead to FORCED ON or FOLLOW RTS.
Forced On
The CTS lead is always on and the RTS lead is ignored.
Follow RTS
The CTS lead is on when the RTS lead is on (and off when the RTS lead is
off).
DSR Option
Set the DSR lead to FORCED ON or NORMAL.
Forced On
The DSR lead is always on.
Normal
The DSR lead is off when the IQ Probe does not receive DSR from the
DSU/CSU on the DCE port.
CD Option
Set the CD lead to FORCED ON or NORMAL.
Forced On
The CD lead is always on.

Chapter 6. DTE Port Configuration
Normal
The CD lead is off when the IQ Probe does not receive CD from the DSU/
CSU on the DCE port.
TC Clock Option (TC CLOCK OPT)
Normal
Clock for DTE's transmit data normal phase.
Inverted
Clock for DTE's transmit data inverted phase. May be used in high speed
circuits (>512 kbps) when the DTE's V.35 interface has high delay. This is
usually indicated by HDLC errors on the IQ Probe's DTE port.
Frame Relay Options (FR OPTS)
These selections apply to the signaling between the router or FRAD and
the IQ Probe DTE port.
T392
Set the timeout (in seconds) between polling intervals. This parameter
needs to be a few seconds longer than the T391 setting of the attached
frame relay device.
N392 and N393
These parameters define the error threshold for the UNI (user to network
interface) formed by the IQ Probe DTE port and the attached frame relay
device. If the error threshold is met, the signaling state status is changed
to down, which indicates a service-affecting condition. This condition is
cleared once N393 consecutive error-free events are received. N392 defines the number of errors required in a given event window, while N393
defines the number of polling events in each window.
6-4
IQ Probe User Manual
61200214L1-20
Chapter 6. DTE Port Configuration
For example:
If N392=3 and N393=4, then if three errors occur within any four events,
the interface is determined inactive.
The status of the connection can be viewed in the STATUS menu under
DTE PORT SIGNALING STATE. The status will return to active once the
threshold is no longer exceeded.
Management DLCI (MGMT DLCI)
To use local PVC management, enter the management data link connection identifier (DLCI). The management DLCI is a special DLCI used between the attached DTE device and the IQ Probe to carry SNMP and
Telnet packets to/from the IQ Probe on the DTE port.
Guidelines for Configuring Management DLCI
If the attached router or FRAD is used to route SNMP/Telnet frames to the
IQ Probe, set the Management DLCI to a unique value (between 16 and
1007) that identifies the virtual circuit between the router/FRAD and the
IQ Probe. The router/FRAD must also be configured to route the IQ Probe
IP address to this DLCI. The IP address and subnet mask for the DTE port
must also be set in the SYSTEM CONFIGURATION menu.
Management PVC Option (MGMT PVC OPT)
If this option is set to ENABLED, the management DLCI is included in the
Full Status response to the router. Enable this option when the management DLCI is used to route management traffic to the IQ Probe.

Signaling Responses (SIG RESPONSES)
This option determines when PVC signaling responses are sent to the router.
Always On
If ENABLED, PVC signaling responses are sent to the router regardless of
the network signaling state. Enable this option when the IQ Probe is used
for dial backup.
Follows Network (FOLLOW NET)
If ENABLED, PVC signaling responses are sent to the router only when the
network signaling state is up. Enable this option when the router is going
to use an alternate path for dial backup.
Always Off
If ENABLED, PVC signaling responses are NOT sent to the router, regardless of the network signaling state. Enable this option to simulate a PVC
failure when the router is going to use an alternate path for dial backup.

DCE PORT
Access the DCE port menus by selecting DCE PORT from the CONFIGURATION menu. Full menu trees for the DCE CONFIGURATION selections are
shown on the enclosed insert. The DCE port terminates the user end of the
frame relay UNI interface. The IQ Probe supports three standard PVC signaling formats: LMI (gang of four), ANSI T1.617-D (Annex D), and ITU
Q.933-A (Annex A). The selected signaling format is used to poll the DCE
end of the UNI interface and retrieve virtual circuit information. Optionally, the polling process can be disabled.
When configuring from a terminal, the screen in Figure 7-1 on page 7-2
will display when DCE PORT is selected.
In this chapter, the terminal selections are listed first followed by

N392 and N393
These parameters define the error threshold for the UNI formed by the IQ
Probe DCE port and the frame relay switch. If the error threshold is met,
the signaling state status is changed to down, which indicates a service-affecting condition. This condition is cleared once N393 consecutive errorfree events are received. N392 defines the number of errors required in a
given event window, while N393 defines the number of polling events in
each window.
For example:
If N392=3 and N393= 4, then if three errors occur within any four events
the interface is determined inactive.
The status of the connection can be viewed in the STATISTICS menu under
DCE PORT S IGNALING S TATE. The status will return to active again once
the threshold is no longer exceeded.
The network service provider should recommend the values
entered into the T391, N391, N392, and N393 fields.
Management DLCI 1 and 2 (DLCI 1 and 2)
Enter the management data link connection identifiers (DLCIs). These
DLCIs are used to carry management traffic to and from the network.
Management DLCI 1 and 2 Mode
Set to DEDICATED if the management DLCI is used only to manage the IQ
Probe (and not used to carry customer traffic). If set to DEDICATED, the
router is not notified of that DLCI. Set to SHARED if the management DLCI
is used for carrying customer traffic and management data.

Maximum PVC Count (MAX PVC COUNT)
Sets the maximum number of PVCs that the IQ Probe will monitor for statistical information. This value determines the amount of history intervals
available for storage. To get the maximum amount of statistical history
storage, set this value equal to the number of PVCs assigned to the frame
relay port. A smaller value increases history interval count but puts some
of the PVC statistics into the unknown category.
History Interval Count (HIST INT COUNT)
Sets the number of history intervals to store for statistics. History intervals
are displayed in the VIEW BY INTERVAL portions of the STATISTICS menus.
These views provide data divided into columns grouped by the interval of
time selected in the HISTORY INTERVAL S IZE field (see History Interval Size
(HIS INT SIZE) on page 9-6 for more information). The HISTORY INTERVAL
C OUNT field determines how many intervals can be stored at a time. The
maximum value allowed is affected by the previously mentioned PVC
Count selection.
PVC Options (PVC CONFIG)
The PVC Options table enables optional features such as delay measurement for each PVC. DLCI numbers and their corresponding committed information rates (CIRs) are supplied by the service provider.
When configuring PVC options using the front panel, the Next,

DBU DLCI
Enter the far end DLCI for each PVC used for dial backup. Only the IQ
Probe that originates the call is required to have this option set. Range is
16 to 1007.
DBU Phone Number
The phone number entry stores the phone number that is used when the
IQ Probe triggers auto dial backup in case of port or PVC failure. The
phone number should correspond to a location that is equipped with an
“Adtran Safety Net” device that is capable of restoring the PVC which is
designated by the DBU DLCI element.
If auto DBU is triggered by port failure, then the DBU CALL ORDER element determines the order of a dialing list for alternate backup locations.
DBU on Inactive
This option works in conjunction with the dial backup criteria option WITH
PVC INACTIVE. For DBU ON INACTIVE option to have an effect on auto DBU
operation, the W ITH PVC INACTIVE option must be set to ENABLE. See Dial
Backup Configuration on page 8-1.
If DBU ON INACTIVE is set for ENABLED and the PVC designated by the
DLCI element in the table entry goes to an inactive or unknown state, the
IQ Probe will dial the phone number designated by the DBU PHONE NUMBER element in the table entry.
GROUP is a special case in which all PVCs that are part of a group must be
inactive or unknown before the auto DBU process is triggered. This special
case is treated as a port failure in which DBU CALL ORDER entry applies.

CIR (Kbps)
Enter the CIR in kbps for the corresponding DLCI. The information is supplied by your service provider and must be entered for each PVC to ensure
accuracy of statistical information.
Seq Num Checking (SEQ #)
Set to ENABLE only if there are IQ products on both ends of the PVC. When
enabled, the IQ Probe tags each frame with a sequence number which is
then used by the remote IQ device to detect lost packets. Lost packet
counts are given in the STATISTICS menus.
Delay Measurement (PVC DELAY)
Set to ENABLE only if there are IQ products on both ends of the PVC. When
enabled, the IQ Probe periodically transmits a loopback frame to the remote IQ device which is then returned to measure round trip delay of each
PVC. Minimum, maximum, and average delay measurements are given in
the STATISTICS menus.
Stats Option (STATS OPT)
This option prioritizes PVCs for STATISTICS counts. The IQ Probe tracks
statistics for a limited number of the PVCs that pass through. This number
is determined in the MAX PVC COUNT field (see Maximum PVC Count
(MAX PVC COUNT) on page 7-5). The three choices for this field are described below.
Auto
If set to AUTO, then statistics will be logged for this PVC if the MAX PVC
C OUNT has not been exceeded. The AUTO selection designates a PVC as second priority to a PVC set to ENABLED.
Enabled
If set to ENABLED, then statistics will be logged for this PVC if the MAX PVC

Answer Always
If this feature is enabled, the unit will answer a call. If disabled, it will not
answer a call. However, the ANSWER ALWAYS option must work in conjunction with the AUTO DBU and ORIGINATE/ANSWER options. The AUTO
DBU option is the controlling option and if it is disabled, the unit will not
answer the call regardless of how ANSWER ALWAYS is set, except for the
DTE DBU which will answer the call regardless of the AUTO DBU setting.
The ORIGINATE/ANSWER feature only appears when the unit is programmed for a nonframe-relay circuit (signaling none). If both ANSWER
A LWAYS and AUTO DBU are enabled, the unit will answer the call even if
it is set to ORIGINATE.
Beeper Option (BEEP OPTION)
If enabled, the IQ Probe issues an intermittent beep while in dial backup.
Password Opt
When enabled, the passwords entered in the DBU PASSWORD fields of
both the near and far end IQ devices are required to match before a dial
backup connection can be made. The setting in this field must also be identical in both units (i.e., they both must be set to either ENABLED or DISABLED).

If data is not retrieved before the Total Time Stored is exceeded,
it is overwritten and cannot be restored. Total Time Stored =
History Interval Size x History Interval Count.
LEDs Reflect
Select DTE STATES or DCE STATES. This selection determines which interface the LEDs on the unit's front panel reflect.
USING THE FRONT PANEL
Configuring the R EAD/WRITE COMMUNITY names requires the entry of letters rather than numbers. When configuring the unit using the front panel,

Terminal Statistics Display Options
DTE port, DCE port, DBU port, and DLCI statistics are given in two formats: VIEW BY INTERVAL and VIEW BY DAY.
View by Interval
In this view, the first column is a running total for the current day. All other columns are grouped into user-configured time frames with the most
recent information displayed on the left. The first column's header displays the current date, and the interval columns display the time the intervals began. In order to categorize the interval columns by date also, the
midnight time stamp is replaced with the date. Note that this column still
represents the timed interval (not a day's worth of information).
To configure the interval time frame, go to the SYSTEM CONFIGURATION
menu under HISTORY INTERVAL SIZE and select the time you want the history interval to be set for (from 5 to 30 minutes, in five minute intervals).
The IQ Probe gathers and displays the information according to the time
selected.
The IQ Probe cuts the first gathering session short in order to
begin falling on the selected time boundary. For example: If the
unit or the statistics information was last reset at 12:03 and the
History Interval is set for five minutes, then the first interval
session will last only two minutes. Therefore, the first interval
column (i.e., the column farthest to the right if no columns have
been deleted yet) normally represents a time shorter than the
other columns.
View by Day
This view provides historical information for the last seven days (not including the current day). The most recent information is displayed on the
left.
The first day's column (i.e., the column furthest to the right)
does not represent a full day's worth of information (unless the
unit or the statistics information was reset at exactly 12 AM).

Layer 3 Statistics
Layer 3 statistical information provides you with a better understanding
of the type of traffic occupying your bandwidth. Configure this menu specifically for your setup by selecting the two protocol types most commonly
found in your network.

IQ Probe User Manual
61200214L1-20
Chapter 10. Statistics
The selections are called PROTOCOL 1 and PROTOCOL 2 and are found in
the SYSTEM portion of the CONFIGURATION menu (see Protocols 1 and 2 on
page 9-5). Layer 3 tracking supports the following four protocols:
•
IP (routed and bridged)
•
IPX (routed and bridged)
•
SNA (ten SNA types as defined in FRF-3)
SNA-Subarea (FID4) with Layer 2 (LLC2)
SNA-Peripheral (FID2) with Layer 2 (LLC2)
SNA-APPN with Layer 2 (LLC2)
SNA-HPR with Layer 2 (LLC2)
SNA-Netbios with Layer 2 (LLC2)

SNA-Peripheral (FID2) without Layer 2 (LLC2)
SNA-APPN without Layer 2 (LLC2)
SNA-Netbios without Layer 2 (LLC2)
SNA-HPR without Layer 2 (LLC2)
•
ARP
For Layer 3 tracking to function, the data must be RFC-1490 encapsulated
data or RFC-2427 encapsulated data (RFC-2427 superseded RFC-1490).
For an IP packet to be recognized, it must be carried by an RFC-2427 IP
header or an RFC-2427 SNAP header for bridged ethernet. If the SNAP
header is carrying a bridged ethernet packet, the MAC header is examined
for the protocol type.
SNAP headers are also examined for IPX and ARP traffic.
The ARP option actually tracks inverse ARP where addresses
are resolved across the WAN link. SNA traffic is recognized
by its RFC-2427 header.
Information is gathered for the two protocol types you choose and is displayed with P1 representing information for PROTOCOL 1 and P2 representing information for PROTOCOL 2.

number.
Px Type (current)
The protocol type currently selected in the CONFIGURATION menu is
displayed in this field.
Interval Remaining
Number of seconds remaining in the current timed interval.
Px Type (listed for each interval)
The protocol type being examined for the given interval is displayed in
this field. When the PROTOCOL type selection is changed (see Protocols 1
and 2 on page 9-5), the new selection is not accepted by the IQ Probe until
the end of the current timed interval.
For example, if the IQ Probe is configured for 5-minute timed intervals,
and the PROTOCOL type selection is changed at 12:25, the change will not
be recognized until 12:30. This allows the unit to display an accurate interval history of the PROTOCOL TYPE field.
When the PROTOCOL type selection is changed, the PROTOCOL
TYPE field (P1 TYPE or P2 TYPE) for the current day total (leftmost column on the VIEW BY INTERVAL screens) displays
MIXED, indicating that the displayed information represents
more than one protocol type. Mixed is also displayed for the day
total on the VIEW BY DAY screen once the 24 hour period is
complete.

Top Talker
The TOP TALKERS S TATISTICS menu provides information regarding the
top five talkers in each direction (Rx and Tx) based on their source IP addresses. This information is useful in diagnosing network problems. If a
user is experiencing slow response times, this screen shows whether the
problem is the result of the line not having enough total bandwidth to support the number of users, or if a small number of users are using excessive
amounts of bandwidth. Lower distribution percentages indicate that
there are too many users for that line. High distribution percentages indicate that some users may be using an excessive amount of bandwidth
(possibly due to the type of applications they are using). See Figure 10-6

PVC Loopback
A PVC loopback test is a non-intrusive loopback option for each PVC.
During this test, the IQ Probe periodically sends test frames to the remote
IQ device which are then returned for analysis. The bandwidth required
is approximately 1 kbps for each PVC in test.
See Figure 11-3 on page 11-3 for the terminal menu.

ANSI
American National Standards Institute. Devises and proposes recommendations for international communications standards.
ASCII
American National Standard Code for Information Interchange. The
standard and predominant 7-bit (8-bit with parity) character code
used for data communications and data processing.
asynchronous
A method of data transmission which allows characters to be sent at
irregular intervals by preceding each character with a start bit, followed by a stop bit.
attenuation
The loss of signal amplitude during transmission. The received signal is lower in signal amplitude than the transmitted signal due to
losses in the transmission medium (resistance in the cable). Attenuation is measured in decibels.
bandwidth
The bandwidth determines the rate at which information can be sent
through a channel (the greater the bandwidth, the more information
that can be sent in a given amount of time).
BECN
Backward explicit congestion notification. A bit set by a frame relay
network to notify an interface device (DTE) that congestion avoidance procedures should be initiated by the sending device.

Appendix D. Glossary
bit
A binary digit. A signal, wave, or state is represented as either a
binary 0 or 1.
bits per second (bps)
The number of bits passing a specific point per second. Examples of
common rates are:
• A Kilobit is one thousand bits per second (kbps)
•
A Megabit is one million bits per second (Mbps)
bridge
A device that supports LAN-to-LAN communications. Bridges may
be equipped to provide frame relay support to the LAN devices they
serve. A frame relay capable bridge encapsulates LAN frames in
frame relay frames and feeds them to a frame relay switch for transmission across the network. A frame relay capable bridge also
receives frame relay frames from the network, strips the frame relay
frame off each LAN frame, and passes the LAN frame on to the end
device. Bridges are generally used to connect LAN segments to other
LAN segments or to a WAN. They route traffic on the level 2 LAN
protocol (e.g. the Media Access Control address), which occupies the
lower sub-layer of the LAN OSI data link layer. See also router.
byte
Generally, an 8-bit quantity of information, used mainly in referring
to parallel data transfer, semiconductor capacity, and data storage.
Also, it is generally referred to in data communications as an octet or
character.
carrier
The provider of the data service to the customer site. Carriers can be
local telephone companies, regional telephone companies or any
inter-exchange carrier such as AT&T, Sprint, or MCI.
CD
Carrier detect. A signal generated by a modem or DSU/CSU. CD
indicates the presence of a carrier signal on a communications link.
channel bank
Equipment in a telephone central office or customer premises that
D-2
IQ Probe User Manual
61200214L1-20
Appendix D. Glossary
performs multiplexing of lower speed digital channels into a higher
speed composite channel. The channel bank also detects and transmits signalling information for each channel; thereby transmitting
framing information so that time slots allocated to each channel can
be identified by the receiver.
CIR
Committed information rate. Less than or equal to the access rate, the
CIR is used by the service provider for rate enforcement when the
network is congested. When rates exceed the CIR, frames may be discarded.
clocking
An oscillator-generated signal that provides a timing reference for a
transmission link. A clock provides signals used in a transmission
system to control the timing of certain functions. The clock has two
functions: (1) to generate periodic signals for synchronization and (2)
to provide a time base.
control port
The electrical interface between the IQ Probe unit and a control terminal. The control terminal is used to communicate commands to the
unit.
CPE
Customer premise equipment. All telecommunications terminal
equipment located on the customer premises including telephone
sets, private branch exchanges (PBXs), data terminals, and customerowned coin-operated telephones.
C/R bit
In the Q.921 protocols, a bit that identifies a data-link-layer frame as
either a command or a response.

CRC
Cyclic redundancy check. A computational means to ensure the
accuracy of frames transmitted between devices in a frame relay network. The mathematical function is computed, before the frame is
transmitted, at the originating device. Its numerical value is computed based on the content of the frame. This value is compared with
a recomputed value of the function at the destination device.
CS
See CTS.
CSU
Channel service unit. A device used to connect a digital phone line
coming in from the phone company to either a multiplexer, channel
bank, or directly to another device producing a digital signal (for
example: a digital PBX, a PC, or data communications device). A
CSU performs certain line-conditioning and equalization functions
and responds to loopback commands sent from the central office. A
CSU regenerates digital signals. It monitors them for problems, and
provides a way of testing the digital circuit.
CTS
Clear to send. A signal on the DTE interface indicating that the DCE
is clear to send data.
dB
The standard abbreviation for decibel. A decibel is a unit of measure
for signal. A decibel is usually the relation between a transmitted signal and a standard signal source. Therefore, 6 dB of loss would mean
that there is a 6 dB difference between what arrives down a communications circuit and what was transmitted by a standard signal generator.
DCE
Data communications equipment. A device that provides all the
functions required for connection to telephone company lines and for
converting signals between telephone lines and DTE. Also see DTE.

DDS
Digital data service. AT&T private line service for transmitting data
over a digital system. The digital transmission system transmits electrical signals directly, instead of translating the signals into tone of
varied frequencies as with traditional analog transmission systems.
Digital techniques provide more efficient use of transmission facilities, resulting in lower error rates and costs than analog systems.
DE
Discard eligibility. A user-set bit indicating that a frame may be discarded in preference to other frames if congestion occurs, to maintain
the committed quality of service within the network. Frames with
the DE bit set are considered Be excess data.
DLCI
Data link connection identifier. A unique number assigned to a PVC
end point in a frame relay network. Identifies a particular PVC endpoint within a user's access channel in a frame relay network and has
local significance only to that channel.
DSU
Data service unit. A device designed to transmit and receive digital
data on digital transmission facilities.
DTE
Data terminal equipment. The end-user terminal or computer that
plugs into the termination point (DCE) of a communications circuit.
The main difference between the DCE and the DTE is that pins two
and three are reversed.
encapsulation
A process by which an interface device places an end device's protocol-specific frames inside a frame rely frame. The network accepts
only frames formatted specifically for frame relay; therefore interface
devices acting as interfaces to a frame relay network must perform
encapsulation. See also interface device and frame-relay-capable interface
device.

the same channel used for data.
ingress
Frame relay frames leaving from an access device in a direction
toward the frame relay network.
interface device
Provides the interface between the end device(s) and a frame relay
network by encapsulating the user's native protocol in frame relay
frames and sending the frames across the frame relay backbone. See
also encapsulation and frame-relay-capable interface device.
IP
Internet protocol. A protocol which provides for transmitting blocks
of data between hosts identified by fixed-length addresses.
ISDN
Integrated services digital network. A network architecture that
enables end-to-end digital connections. The network supports
diverse services through integrated access arrangements and defines
a limited set of standard, multipurpose interfaces for equipment vendors, network providers, and customers. Interworking with a public
switched telephone network is retained.

PVC
Permanent virtual circuit. A frame relay logical link, whose endpoints and class of service are defined by network management.
Analogous to an X.25 permanent virtual circuit, a PVC consists of the
originating frame relay network element address, originating data
link control identifier, terminating frame relay network element
address, and termination data link control identifier. Originating
refers to the access interface from which the PVC is initiated. Terminating refers to the access interface at which the PVC stops. Many
data network customers require a PVC between two points. Data terminating equipment with a need for continuous communion use
PVCs. See also DLCI.

router
A device that supports LAN-to-LAN communications. Routers may
be equipped to provide frame relay support to the LAN devices they
serve. A frame-relay-capable router encapsulates LAN frames into
frame relay frames and feeds those frame relay frames to a frame
relay switch for transmission across the network. A frame-relaycapable router also receives frame relay frames from the network,
strips the frame relay frame off of each frame to produce the original
LAN frame, and passes the LAN frame on to the end device. Routers
connect multiple LAN segments to each other or to a WAN. Routers
route traffic on the Level 3 LAN protocol (e.g., the internet protocol
address). See also bridge.
