Chapter 1 Introduction

PRODUCT OVERVIEW

The ADT RAN DSU IQ provides the visibility and control needed
for both the physical and logical connections made in frame relay
networks. The DSU IQ provides logical layer monitoring and
management for frame relay. Each permanent virtual circuit (PVC)
accessed thro ugh a DSU IQ is managed end-to-end as if it were a
leased line connection. Real-time sta tistics on throughput,
bandwidt h utiliza t ion , availability, bursting, congestio n, and
network delay are collected and stored in the Frame IQ MIB
(management information base). This information can then be
gathered by management systems and used to monitor network
health and perform long-term network planning.

The unit's embedded SNMP (simple network management
protocol) agent provides complete SNMP access to the unit. SNMP
access is available through the DTE or network port or through an
integral SLIP (serial l ine internet protocol) or PPP (point-to-point
protocol) async port. The DSU IQ's unique modular approach
provides optional 10BaseT ethernet access for SNMP.

Chapter 1. Introduction

DSU IQ Features

• Co mplete and comprehensive frame relay monitoring

• R e a l- time measurement of ban dwidth utilization, comm itte d
information rates (CIRs), and excess burst rates on each PVC

• True non-intrusive, in-ba nd transmission of statistics

• Embedded SNMP and Telnet through the DTE, network, or
SLIP/PPP port (or through the optional ethernet interface)

• Dial backup (DBU) available with DBU card s; option s in clude
4-wire Switched 56 (SW56), V.34, and ISDN

• Control port provides SLIP and async PPP access to SNMP or
VT-100 terminal configuration

• End-to-end network round trip delay measurements for
network optimization

• 10BaseT ethernet port available with ethernet card

• Frame IQ MIB is standard ANSI format compatible with
popular enterprise reporting systems

• Optional IQ View™ software system provides a cost-effective,
easy-to-use GUI (graphical user interface) for performance
management

• Standard DTE (data terminal equipment) interfaces

The 4-wire SW56 DBU card is compatible with AT&T Accunet and
Sprint SW56 type services. The V.34 DBU card allows switched
backup over the public switched telephone network (PSTN). The
ISDN 1B+D card supports a U-interface to the Basic Rate ISDN and
is compatible with National ISDN and AT&T DMS.

The DSU IQ provides both V.35 and EIA-232 electrical and physical
DTE interfaces to accommodate a variety of applications.

To ensure a reliable connection, the unit features an extended
receiver capability which perm its operation over long loops (3.4
miles or 5.5 km of 26 AWG at 56 kbps).

UNDERSTANDING FRAME RELAY

Frame relay is a wide area network (WAN) service designed to
minimize physical connec tions . Th is is a cco mplished 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 the user's customer premise equipment
(CPE) such as the ADTRAN DSU IQ.

ANSI (American National Standards Institute) standards describe
how each frame must be constructed to provide inter-operability
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 iden tifier ). The he ade r information
also contains bit s use d for network co nges tion 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 protoc ol session is est ablished. T he network service
provider assigns these DLCIs at subscription time. SVCs, on the
other hand, have DLCIs dynamic ally a ssigned 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 v al id until the c a ll is disc onn e cte d and may be
assigned a different value each time a call is requested.

Chapter 1. Introduction

DDS OPERATION

DDS (dig ital data service) is a nationw ide service that a llo w s
interconnection and transp ort of data at speeds up to 64 kbps. The
local exchange carriers provide the local loop service to DDS
customers and may provide data for routing Inter-LATA to an
inter-exchange carrier. The DSU IQ supports 56 or 64 kbps DDS
service rates yielding DTE rates of 56 kbps and 64 kbps.

SNMP management capability is provided in-band with support
for RFC 1315 (frame rel ay DTE MIB), RFC 1213 (MIB II), and
ADTRAN Ente rprise MIB. MIB files are available from ADT R AN
in the support section of the ADTRAN web page at
www.adtran.com. Telnet capability is also supported. For non­SNMP environments, VT-100 and front panel operation is
supported.

The DSU IQ's embedded SNMP feature allows the unit to be
accessed and controlled by a network manager through the DTE or
network por t, thr o ugh a devi ce ru nn ing SLI P or asyn c PPP pro toc ol
(connected to the CONTROL port of the DSU), or through a LAN.
LAN connection requires the optional ethernet card
(P/N 1204005L1). This card provides a 10BaseT ethernet interface
to the LAN.

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. SNMP has three basic components:

Network Manager

Control program t hat collect s, controls, and presents data pertinent
to the operation 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 retu rns requested inf o rmation or invokes
configuration changes initiated by the manage r.

MIB

Index to the organized data wi thin a network dev ice. It defines the
operation parameters that can be controlled or monitored.

1-4 DSU IQ User Manual 61200212L1-1

TELNET

Telnet provides a pas swo rd-protecte d, remo te login facility to t he
DSU IQ. Telnet allows a user on a network manager to control the
DSU IQ through the terminal menus.

DIAL BACKUP OPERATION

The DSU IQ dial backup (DBU) option cards allow frame relay
circuit outage recovery for one user-to-network interface (UNI) at a
time. The DSU IQ can be configured to originate a call based on
physical layer conditions and/or PVC signaling outages. Once the
criteria is met, the DSU IQ establi shes a call to the configured
phone number and the connection is used to carry traffic for the
PVC(s) configured for DBU operation.

In the case of P VC ou tages (not physical l ayer por t fail ur e), the DSU
IQ’s two-port design allows t he DSU I Q receiving the ca ll to
continue to use the T1 frame relay circuit for VCs that are not
affected by the outage, while using the DBU interface for PVCs that
are inactive due to the outage. A DSU IQ with multiple PVCs to
multiple site s can also originat e a c all to on e si t e durin g an outage
and restor e connectio n for PVCs to that destinat ion.

Chapter 1. Introduction

The DSU IQ'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 compa tible with other ADTRAN
products supporting DBU. The backup options are described in the
following section, Interface Card Options on page 1-6. Contact the
local telco pro vider to determine w hich services are available in
your area. See Applications on page 4-1 for more information,
including an ex am p le of a dial backup application.

Chapter 4 Applications

This chapter provides examples of some common DSU IQ
management application 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 applications 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 DSU IQ is management
flexibility. The DSU IQ front panel interface provides complete
configuration capabilities and viewing o f key frame relay statistics
information. Other management options described in this chapter
provide configura tio n and dia gnost ic s capabilit ie s as well as a ll­inclusive s tatistics information.

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 flowi ng through the frame relay device. The
DSU IQ can be managed though an established Telnet session or an
SNMP-based network manager like HP OpenView
or SunNet Manager

The ADTRAN DSU IQ MIB is available in the support section of the
ADTRAN web page at www.adtran.com.

SNMP and T el net management is provided by one of the following
interfaces:

• A device (i.e., a router) ru nning SLIP prot ocol. Connection is
made through the DSU IQ's Cont rol port.

• A device (i.e., a router) running async PPP protocol.
Connection is m ade through the DSU IQ's Control port.

• A LAN. Connection is made through the optional 10BaseT
ethernet interface provided on the ethernet card (P/N
1204005L1).

In-Band Management

The ADTRAN DSU IQ supports three modes of in-band
management using the frame relay structure of PVCs. These modes
are local (see Figure 4-3 on pa ge 4-6), shared (see Figure 4-4 o n page
4-8), and dedicated PVC management ( see Figu re 4-5 on page 4-10) .
All three types support complete SNMP management as well as
Telnet capabi lities .

Local PVC Management

Local PVC management refers to a PVC created between the DSU
IQ and the frame relay router on the DTE interface of the DSU IQ.
This type of ma na gem ent is id e al w hen local ma na gem e nt is
needed but an ethernet connection is not available. To support this
type of management it is required that all traffic on the selected
PVC be RFC 1490 encapsulated, noncompressed IP traffic.

The local PVC is sent ou t o f th e WAN serial port of the router as
normal WAN traf fic and is terminated in the DSU IQ. Since t he
DSU IQ 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 DSU IQ. Accomplish th is by setting a
value (between 16 and 1007) fo r the DTE management DLCI on the
DSU IQ to a value not used by the frame relay network.

612002 12L1-1 DSU IQ User Manua l 4-5

Chapter 4. Applications

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 DSU is
lost.

Shared PVC Management

Shared PVC management refers to a PVC that is used for normal
data traffic between loc a tions. The DSU IQ monitors this PVC for
packets that contain its IP address. When the DSU IQ detects a
packet containing a destination IP address that matches the DSU IQ
IP address, the unit intercepts the packet and processes its TCP/IP
information. T o support this type of management it is required that
all traffic on the selected PVC be RFC 1490 encapsulated,

Shared PVC management is used to manage remote DSU IQs
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 DSU IQ 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 getting to 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 DSU IQ. This is
an ideal configuratio n for third-party management . It isolates the
customer’s data traffic from network manage m ent traffic and it
also acts as a fire-wall that restricts management data to the DSU.
Dedicated PVC management is also ideal when the user wants to
guarantee access to a remote DSU regardless of the state of the
remote LAN.

DIAL BACKUP APPLICATION

The DSU IQ dial backup (DBU) options allow frame relay circuit
outage recovery for one user to network interface (UNI) at a time.
The DSU IQ can be configured to originate a call based on physical
layer conditions (i.e., port failures) PVC signaling loss, and/or PVC
outages. Once the criteria is met, the DSU IQ establishes a call to the
configured phone number (see Table 4-1 on page 4-13) and the
connection is used to carry traffic for the PVC(s) configured for
DBU operation.

The DSU IQ's two-port design allows the DSU IQ receiving the call
to continue to use the DDS 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 int erv enti on) by modi fying th e st at us of PVCs that ar e
in DBU state to active when the PVC status is given to the DTE. A
DSU IQ with multip le PVCs t o m ult ip le sit e s can also origin a te a
call to one site d uri ng an outage an d res tore connect ion for P VCs to
that destination. Since the DSU IQ can only make one call at a time,
the other PVCs to other sites in this scenario will be inactive.

Chapter 4. Applications

Information entered into the PVC C

ONFIGURATION

Table (see Table
4-1 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 DSU IQ 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 P

FRAME RELAY OPTIONS (FR OPTS)

The frame relay protocol is a synchronous protocol used to
concentrate two differ ent devices in to a common fra me relay link to
the network. The DSU IQ accepts frame relay frames from a router
or a FRAD (frame relay access device) and routes to/from the
network port based on the DLCI address.

T392

Set the timeout (in seconds) between polling intervals. This
parameter needs to be a few secon ds longer than th e T391 se ttin g of
the attached frame relay device.

N392 and N393

Thes e pa ra m e te r s de f ine the error thresh o ld fo r the UNI (user to
network interface) formed by the DSU IQ DTE port and the
attached frame relay device. If the error threshold is met, the
signaling state status is changed to down, which indi cates a
service-affect ing condition. This cond it ion 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.

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 S

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 DSU IQ to
carry SNMP and TELNET packets to/from the DSU IQ on the DTE
port.

Guidelines for Configuring Management DLCI

If the attached router or FRAD is used to route SNMP/TELNET
frames to the DSU IQ, set the Management DLCI to a unique value
(between 16 and 1007) that identifies the virtual circuit be tween the
router/FRAD and the DSU IQ. The r outer/FRAD must also be
configured to route the DSU IQ IP address to this DLCI. The IP
address and subnet mask for the DTE port must also be set in the

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 t h e u n k n o wn cate g o ry.

History Interval Count (HST INT COUNT)

Sets the number of history intervals to store for statistics. History
intervals are displayed in the View by Interval portions of the
