Introduction
PRODUCT OVERVIEW
The ADTRAN TSU IQ Rackmount provides the visibility and control needed for both the physical and logical con­nections made in frame relay networks. The TSU IQ Rack­mount provides logical layer m onitoring and management for frame relay. Each permanent virtual cir­cuit (PVC) accessed through a TSU IQ Rackmount is man­aged end-to-end as if it were a leased-line connection. Real-timestatistics on throughput,bandwidth utilization, availability, bursting, congestion, and network delay are collected and stored in the Frame IQ MIB (management informationbase). 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 theunit.SNMPaccessisavailablethroughtheDTEor network port or through an integral SLIP (serial line inter­net protocol) or PPP (point-to-point protocol)async port.
10BaseT ethernet access is also provided for SNMP.

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. Virt ual circuits are addressed using header information at the beginning of each frame. These frames are formatted by the Enterprise Networking users (END) such as the ADTRAN TSU IQ Rackmount.
ANSI (American National Standards Institute) standards describe how each frame must be constructed to provide interoperability between END 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.
Chapter 1. Introduction
Frame relay virtual circuits may be definedas permanent (PVC) or switched (SVC). PVCs have the same DLCI for a givenpatheachtimeauserprotocolsessionisestab­lished. 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 END 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.

Chapter 1. Introduction
T1/FT1 OVERVIEW
The telephone companies (telcos) have used T1 digital communications links for voice transmission since the early sixties. The D4 channel bank is an example of a T1 digital carrier system that was introduced in the mid-sev­enties and is still widely used by the telcos. Communica­tion demands of businesses continued to grow to the point that the telcos began offering T1 service directly to the public. D4 channel banks began to be used for T1 in corporate network topographies for voice. The technolog­ical advances in computer development also created a de­mandforT1datacommunication,whichnowisalarge part of the T1 traffic.
T1 Service Offerings
T1 is a digital service that the service providers deliver to the user over two pairs of wires. The signal operates at
1.544Mbps and is usually extended by repeaters installed
about every mile after the first 6000 feet. The T1 signal is divided into 24 time slots or digital signal level zeros (DS0s) which operate at 64 kbps. Each time slot is occu­pied by digitized voice or by data.
The T1 signal originally used a type of framingknown as D4 superframe, which identifies how the T1 is multi­plexed. Extended superframe (ESF) is an enhancement of that framing format. ESF provides a non-disruptive means of full-time monitoring on the facility datalink (FDL). The service providers originally used ESF to mon­itor the performance of their service offering. Since the in­troduction of ESF, equipment that is installed in private networks can also provide the same performance infor­mation to the user.
1-4 TSU IQ Rackmount User Manual 61200277L1-1
Fractional T1
FractionalT1 (FT1) letsthe buyer purchaseless than a full T1 circuit between two points. Most carriers offer frac­tional T1 in increments of 56 or 64 kbps. Connection is made to the same network elements. The network allows multiple users to share the same interoffice T1 band­width.
FT1 remains almost exclusively an inter-exchange carrier (IXC) service. Local exchange carriers (LECs) typically do not offer FT1, so the user's proximity to the IXC's point-of­presence (POP) is key in the savings that fractional T1 of­fers.
SNMP MANAGEMENT
SNMP management capability is provided in-band with support for RFC 1315 (frame relay DTE MIB), RFC 1213 (MIB II), RFC 1406 (DS1/E1 MIB), 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. Fornon-SNMPenvironments,VT-100 andfrontpanel op­eration are supported.
Chapter 1. Introduction
The TSU IQ Rackmount's embedded SNMP feature al­lows the unit to be accessed and controlled by a network manager in-band at the DTE or network interface, out-of­band at the control port via SLIP or async PPP, or using a LAN connection.
The term SNMP 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 databases. The three basic components of SNMP follow:
Network Manager
Control program that collects, controls, and presents data pertinent to the operation of the network devices. It resides on a network management station.
61200277L1-1 TSU IQ Rackmount User Manual 1-5
Chapter 1. Introduction
TELNET
Agent
Control program that resides in each connected network device. This programresponds 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 provides a password-protected, remote login facil­ity to the TSU IQ Rackmount. TELNET allowsa useron a network manager to control the TSU IQ Rackmount through the terminal menus.
DIAL BACKUP OPERATION
The TSU IQ Rackmount dial backup (DBU) option cards providesingleormultiplesitebackupdependingonthe DBU card option selected. The TSU IQ Rackmount 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 TSU IQ Rackmount establishes a call to the configured phone number and the connection is used to carry traffic for the PVC(s) configured for DBU operation.

Applications
Thischapterprovidesexamplesof somecommon TSU IQ Rackmount 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 man agement DLCI must be RFC 1490 encapsulated IP traffic.
MANAGEMENT APPLICATIONS
One of the main advantages of t he TSU IQ Rackmount is management flexibility. The management options de­scribed in this ch apter provide configuration and diag­nostics capabilities as well as all-inclusive statistics information.
Local VT-100 Terminal Management
Connect a VT-100 terminal to the TSU IQ Rackmount CONTROL port. This interface provides full-screen con­figuration and all-inclusive statistics access. VT-100 man­agement also allows for remote configuration. Through

All PVC-based in-band management traffic must be noncompressed IP and use RFC 1490 encapsulation.
61200277L1-1 TSU IQ Rackmount User Manual 4-5
Chapter 4. Applications
Local PVC Management
Local PVC management refers to a PVC created between the TSU IQ Rackmount and the frame relay router on the DTE interface of the TSU IQ Rackmount (see Figure 4-3). 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 TSU IQ Rackmount. Since the TSU IQ Rackmount re­sponds to Inverse ARP, it is notnecessary to set up a static routein the router.The router willdiscover the IP address automatically; however, it will be necessary to set up a lo­cal PVC between the router and the TSU IQ Rackmount. This is done by setting a value (between 16 and 1007) for the DTE management DLCI on the TSU IQ Rackmount 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.
When using local PVC management, if the remote router goes down, access to the remote TSU is lost.

Shared PVC Management
Shared PVC management refers to a PVC that is used for normal data traffic between locations (see Figure 4-4). The TSU IQ Rackmount monitors this PVC for packets that contain its IP address. When the TSU IQ Rackmount de­tects a packet containing a destination IP address that matches the TSU IQ Rackmount IP address, the unit inter­ceptsthe packet and processesits 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 TSU IQ Rackmounts without being dependent on services from the remote router. This usually requires a static route at the host location.
ONFIGURATION>SYSTEM>TRAPMGROPTIONS
.
By setting local PVC management and shared PVC management on the remote TSU IQ Rackmount, 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.

DIAL BACKUP APPLICATION
The TSU IQ Rackmount dial backup (DBU) option cards provide single or multiple site backup, depending on the DBU card option selected. The TSU IQ Rackmount 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 TSU IQ Rackmount establishes a call to the configured phone number (see Table 4-1 on page 4-14) and the connection is used to carry traffic for the PVC(s) configured for DBU operation.
InthecaseofPVCoutages(notphysicallayerport failure), the TSU IQ Rackmount's two-port design allows the TSU IQ Rackmount receiving the call to continue to usetheT1framerelaycircuitforPVCsthatarenot 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.
A TSU IQ Rackmount 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. With all DBU cards except for the PRI card, you can make only one call at a time. The other PVCs to other sites in this scenario will be inactive. If you have a PRI card you can originate or answer up to 23 calls.
Information entered into the PVC Configuration table (see Table 4-2 on page 4-14) 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 TSU IQ Rackmount 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

field set
for a null entry. Enter a space character from the VT-100 terminal to create a null entry for DBU P

field. The DBU phone number information is only required for
the TSU IQ Rackmount originating the call. Examples of dial backup for non-PRI and PRI, are shown
in the following sections.
4-12 TSU IQ Rackmount User Manual 61200277L1-1
DBU Application 1 (non-PRI)
The following application shows the critical configura­tion required for a case where all end points of the frame circuit are equipped with single call DBU units (see Fig­ure 4-6). This setup allows any remote site to place a call to the host site or the host site to place a call to each re­mote site based on PVC failure. This setup also allows the host to design primary and alternate sites to call based on port failure criteria using the call order parameter.

None
No flow control is used and the TSU IQ Rackmount drops frames during severe congestion while in DBU operation.

Hardware
The TSU IQ Rackmount 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
Normal
Clock for DTEs transmit data normal phase.
Inverted
Clock for DTEs transmit data inverted phase. This set­ting 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's DTE port.
Frame Relay Options
The frame relay protocol is a synchronous protocol used to concentrate two different devices into a common frame relay link to the network. TheTSU IQ Rackmount accepts frame relay frames from a router or a FRAD (frame relay accessdevice) and routes to/from the network port based on the DLCI address.
T391
Set the time-out (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 TSU IQ Rack­mount DTE port and the attached frame relay device. If the errorthreshold is met, the signaling state status is
OWN
changed to D
, 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.

Management DLCI
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

.The status will return to active once the threshold is no longer exceeded.
To use local PVC management, enter the management DLCI. The management DLCI is a special DLCI used be­tween the a ttach ed DTE device and the TSU IQ Rack­mount to carry SNMP and TELNET packets to and from the TSU IQ Rackmount on the DTE port.
Guidelines for Configuring Management DLCI

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 begin. 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).

and select the time you want the history interval to be set for (from 5 to 30 minutes, in five minute intervals). The TSU IQ Rackmount gathers and displays the information ac­cording to the time selected.
The TSU IQ Rackmount 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 lastreset 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.
This view provides historical information for the last sev­en days (notincludingthe 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).
