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 long-term network planning.

Introduction
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 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

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.
2 IQ Probe User Manual 61200214L1-1
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.
Chapter 1. Introduction
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.
61200214L1-1 IQ Probe User Manual 3
Chapter 1. Introduction
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 by the manager.
MIB
Index to the organized data within a network device. It defines
the operation parameters that can be controlled or monitored.
TELNET
TELNET provides a password-protected, remote login 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 allow frame relay
circuit outage recovery for one user-to-network interface (UNI)
at a time. The IQ Probe can be configured to originate a call
based on physical layer conditions and/or PVC signaling loss.
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 DBU operation.
These cards allow the unit receiving the call to continue to use
the network 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 cards are field-installable by the customer. See the chapter
Installation for information on installing DBU cards. The DBU
cards are compatible with other ADTRAN ESP products
supporting DBU. The backup options are described in the
following section, ESP Card Options. Contact the local telco
provider to determine which services are available in your area.
See the chapter Applications 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.
61200214L1-1 IQ Probe User Manual 23
Chapter 4. Applications
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 gives an example of a VT 100
application.
VT 100 remote mode is proprietary and non-intrusive. Therefore, you
can perform all VT 100 management functions without disrupting the
flow of data.

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.

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), shared (see Figure 4-4), and
dedicated PVC management (see Figure 4-5). All three types
support complete SNMP management as well as TELNET
capabilities.
61200214L1-1 IQ Probe User Manual 27
Chapter 4. Applications
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 responds 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.
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.
30 IQ Probe User Manual 61200214L1-1
Chapter 4. Applications
Since the unit is set up for shared PVC management, all management
traffic will be intercepted prior to reaching the remote router.

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.

The configuration requirements for dedicated PVC management
are identical to those listed for shared PVC management. See the
previous section, Minimum Configuration Requirements for Shared
PVC Management, for more information.
DIAL BACKUP APPLICATION
The IQ Probe dial backup (DBU) options allow frame relay
circuit outage recovery for one user to network interface (UNI) at
a time. Therefore, if the host site goes down, only one remote
site (the primary remote) is backed up. The IQ Probe can be
configured to originate a call based on physical layer conditions
and/or PVC signaling loss. Once the criteria are met, the IQ
Probe establishes a call to the configured phone number (see
Table 4-A) and the connection is used to carry traffic for the
PVC(s) configured for DBU operation.

61200214L1-1 IQ Probe User Manual 33
Chapter 4. Applications
During dial backup, the IQ device receiving the call continues to
use the 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. 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. Since the IQ Probe can only
make one call at a time, the other PVCs to other sites in this
scenario will be inactive.
Information entered into the PVC Configuration Table (see Table
4-B) 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 DLCI field set
to zero.
The DBU DLCI information is only required for the IQ Probe
originating the call. In cases such as remote sites establishing
calls to host sites, the remote site should have only non-zero
values for the DBU DLCI fields in the PVC Configuration Table.
Only PVCs that are used in DBU should have the DBU DLCI set to a
non-zero value.
The range for the DBU DLCI field is from 16-1007. Therefore,
you cannot manually enter 0 for the PVCs not used in DBU.
When an entry is first created with the ADD selection, it is set to
0 by default. To reset a previously configured DBU DLCI to 0,
delete the entry and then add it back in (using the DELETE and
ADD selections).

Hardware
The IQ Probe varies the DTE TC clock as necessary to relieve
congestion during DBU operation.
FECN/BECN
While in a congested state during DBU 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.

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.
46 IQ Probe User Manual 61200214L1-1
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.
Chapter 6. DTE Port Configuration
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.
61200214L1-1 IQ Probe User Manual 47
Chapter 6. DTE Port Configuration
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.

Configuring the 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 in Figures 5-2 (Terminal Configuration Menu
Tree) and 5-3 (Front Panel Configuration Menu Tree) of the Configu-
ration Overview chapter. 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 will appear when DCE Port is selected.
In this chapter, the terminal selections are listed first followed by the
Front Panel selections in parenthesis (if the names differ).

Signaling Type (SIGNAL)
Set the signaling type option to match the DCE signaling type.
Choices are none, LMI (gang of four), ANSI T1.617-D (Annex D),
ITU-T Q.933-A (Annex A), or auto. AUTO mode forces the IQ
Probe to use the same signaling type as the attached frame relay
DTE. If AUTO is selected and there is no DTE device attached,
the IQ Probe uses ANSI T1.617-D signaling type.
T391
Set the time (in seconds) between polls to the frame relay network.
61200214L1-1 IQ Probe User Manual 51
Chapter 7. Configuring the DCE Port
N391
Determine how many link integrity polls occur in between full
status polls.
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 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.
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 Signaling State. 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 (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.
52 IQ Probe User Manual 61200214L1-1
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 Size field (see the chapter System Configuration for more
information). The History Interval Count field determines how
many intervals can be stored at a time. The maximum value
allowed is affected by the previously mentioned PVC Count
selection.

information on front panel operation.
DLCI
Enter the DCE port's DLCI.
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.
61200214L1-1 IQ Probe User Manual 53
Chapter 7. Configuring the DCE Port
Only PVCs that are used in DBU should have the DBU DLCI set to a
non-zero value.
The range for the DBU DLCI field is from 16-1007. Therefore,
you cannot manually enter 0 for the PVCs not used in DBU.
When an entry is first created with the ADD selection, it is set to
0 by default. To reset a previously configured DBU DLCI to 0,
delete the entry and then add it back in (using the Delete and
Add selections/keys).
CIR (Kbps)
Enter the CIR (committed information rate) 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

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).
70 IQ Probe User Manual 61200214L1-1
Chapter 10. Statistics
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
