Page 29: Chapter 1. Introduction
The DSU IQ provides logical layer monitoring and management for frame relay. Each permanent virtual circuit (PVC) accessed through a DSU IQ 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 in the Frame IQ MIB (management information base).
Page 30: Dsu Iq Features
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 permits operation over long loops (3.4...

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.
Page 32: Snmp Management
SNMP 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 port, through a device running SLIP or async PPP protocol (connected to the CONTROL port of the DSU), or through a LAN.
Page 33: Telnet
Chapter 1. Introduction TELNET Telnet provides a password-protected, remote login facility to the 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.
Page 34: Interface Card Options
Rate ISDN service provides a switched 56/64 kbps circuit. DCE Card This module connects an external DCE device to the DSU IQ for the purpose of using an external DSU/CSU to support access rates up to 512 kbps. The DCE card is inserted into the DBU card slot, but it is not used for dial backup.

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 of key frame relay statistics information.
Page 58: Local Vt-100 Terminal Management
Chapter 4. Applications Local VT-100 Terminal Management Connect a VT-100 terminal to the DSU IQ 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 DSU IQ is fully accessible for configuration, diagnostics, and statistics viewing.

Once these options are configured, the unit may be accessed using SNMP/Telnet. Control Port Mode If necessary, select SLIP or PPP as the DSU IQ Control port mode. If the ethernet card is the interface type, this parameter does not affect setup.
Page 61: Trap Manager Ip Address
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 management is ideal when local management 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.

Page 66: Dedicated Pvc Management
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 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 DSU.
Page 67: Dial Backup Application
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.

Page 79: Frame Relay Options (Fr Opts)
The frame relay protocol is a synchronous protocol used to concentrate two different devices into a common frame 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.
Page 80: Management Dlci (Mgmt Dlci)
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 between the router/FRAD and the DSU IQ.
Page 81: Chapter 7. Network Port Configuration
ONFIGURATION 7-2. The network port terminates the user end of the frame relay UNI interface. The DSU IQ supports three standard PVC signaling formats: LMI, ANSI T1.617-D, and ITU Q.933-A. The selected signaling format is used to poll the network end of the UNI interface and retrieve virtual circuit information.

Page 84: Frame Relay Options (Fr Opt)
ITU-T Q.933-A (Annex A), or A mode forces the DSU IQ to use the same signaling type as the attached frame relay DTE. If is selected and there is no DTE device attached, the DSU IQ uses ANSI T1.617-D signaling type. T391 Set the time (in seconds) between polls to the frame relay network.
Page 85: N392 And N393
N392 and N393 These parameters define the error threshold for the UNI formed by the DSU IQ network 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.
Page 86: Max Pvc Count
Chapter 7. Network Port Configuration Max PVC Count Sets the maximum number of PVCs that the DSU IQ 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.
Page 87: Dbu Dlci
DBU Phone Number The phone number entry stores the phone number that is used when the DSU IQ triggers auto DBU 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.
Page 88: Dbu Call Order
DSU IQs on both ends of the PVC. NABLE When enabled, the DSU IQ tags each frame with a sequence number which is then used by the remote DSU IQ to detect lost packets. Lost packet counts are given in the Statistics menus. Delay Measurement (PVC DELAY) Set to E only if there are DSU IQs on both ends of the PVC.

The DSU IQ gathers and displays the information according to the time selected. The DSU IQ 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 only last two minutes.
