OVERVIEW

The EMU-830 provides management for HDSL and G.SHDSL circuits using either of the following methods:

• One or more shelves of HDSL or G.SHDSL circuits can be managed by connecting a management terminal (or PC with terminal emulation software) to the EMU-830 of one shelf. The management terminal (or PC) can be connected to the EMU-830 either directly (or through modems over a dial-up network). When two or more shelves are present, the Ethernet ports of each shelf can be interconnected to form a Local Area Network (LAN). This method of management is referred to as Multishelf Terminal Access Option (Multishelf TAO).

• One or more shelves of HDSL or G.SHDSL circuits can be managed over a LAN using the Simple Network Management Protocol (SNMP). SNMP can access a shelf through its 10BASE-T Ethernet port or through its Serial Line Interface Port (SLIP) over dial-up modem connections. These methods of management are referred to as SNMP through LAN and SNMP through SLIP. The StarGazer application can be used to manage WorldDSL shelves with the EMU-830 using SNMP through LAN.

• Management of a single shelf or multshelf TAO using Telnet.

The EMU-830 List 4A and List 6A are CE marked.

NEW FEATURES

MAJOR COMPONENTS

Major components of the EMU-830 management unit include:

• 68302 processor

• 2 MB Flash RAM program memory

• Ethernet 10BASE-T port

• Asynchronous Serial Line Internet Protocol (SLIP) port (RS-232/RS-485)

• Front panel V.24 (RS-232) console port

• Audible and visual relays for critical, major, and minor alarms

• Backup timing circuit for external shelf clock (EMU-830 List 6A only)

The EMU-830 Flash RAM program memory permits firmware upgrades through TFTP or Xmodem downloads (see “BOOTP and TFTP Protocols” on page 1-9 and “Xmodem Protocol” on page 1-9).

Note: A total or partial failure of the EMU-830 affects only the centralized management capabilities of the

system, it does not affect the DSL circuits deploye d in the shelf. In case of EMU-830 failure, the HDSL cards can be managed directly from their front panel V.24 Craft port. To use the local management RS-232 interface of an HDSL card it is necessary to remove the EMU-830 from the shelf. To manage a G.SHDSL card using an RS-232 interface, it is not required to remove the EMU-830 from the shelf.

MULTISHELF TAO

Multishelf TAO is supported through the EMU-830 front panel V.24 console port and provides an asynchronous, maintenance terminal, auto-baud interface where you can:

• Monitor all shelf and DSL circuit alarms through a single common screen

• Communicate to a selected shelf and DSL card using the standard line unit console menus

• Set up network configuration parameters and SNMP parameters

• Configure the common equipment and shelf-wide alarms

Figure 1-2 on page 1-4 illustrates local management of a single shelf using TAO. The shelf communicates with the

local terminal (or PC) through the EMU-830 V.24 console port. Figure 1-3 on page 1-4 illustrates remote management of multiple shelves at two sites using Multishelf TAO. Up to 32 shelves at each site are connected over a LAN. The IP address and subnet mask are configured to place all shelves at one site on the same subnet. Each multishelf network communicates with the common network management station over the dial-up Public Switched Telephone Network (PSTN).

Multishelf TAO is also supported using Telnet to 10BaseT port of an EMU-830.

Figure 1-3. Remote Management of Multiple Shelves at Two Sites Using Multishelf TAO

The Multishelf TAO firmware allows the DSL circuits in a single shelf or a network of shelves to be managed from a single point-of-access (the EMU-830 console port of one shelf or using a Telnet session to one EMU-830). The alarm status for each shelf in a multishelf network can be viewed on a single Network screen (Figure 1-4 on page 1-

5), and the alarm status of each DSL circuit in a selected shelf can be viewed on a single Main Menu screen (Figure 1-5 on page 1-5). Each EMU-830 constantly monitors the DSL cards in its shelf for alarm conditions and

automatically updates the alarm status. From the T AO Network screen (Figure 1-4 on p age 1-5) , you can access any shelf in the network and then, from the

Main Menu screen (Figure 1-5 on page 1-5), log into any DSL card installed in the shelf. Logging into an DSL card provides access to that card’s maintenance menus and is equivalent to connecting a terminal directly to the Craft port on the HDSL card.

Note: HDSL cards cannot be directly managed from their front-panel craft port when the EMU-830 is

installed in the shelf. G .SHDSL (UTU-91x an d WD92xGx) cards can be managed from their front-p anel craft port when the EMU-830 is installed in the shelf. Telnet can also be used to manage multiple EMU-830s using multishelf TAO in the same lo gical IP networ k.

September 25, 2006 Chapter 1: Overview

Figure 1-4. Multishelf TAO Network Screen

Figure 1-5. Multishelf TAO Main Menu Screen

A multishelf network is created by connecting the local area network (LAN) to the 10BASE-T Ethernet connector available on a shelf. Each shelf must have an EMU-830 management unit installed. A VT100 terminal (or PC) is connected either locally or remotely (through modems), or through Telnet access to the console port of one EMU in the network. The shelf containing this EMU is called the local shelf. The local shelf coordinates communication with all other shelves in the network, which are called the remote shelves.

It is not necessary for you to explicitly identify each shelf in the netwo rk, as the local she lf automatically discovers them. You must, however, pre-configure the EMU in each shelf with a unique IP address and subnet mask to place all the shelves on the same subnet.

Note: Shelf networks cannot be connected through a router because the local shelf uses UDP-broadcast

messages as a mechanism to automatically discover other shelves in the network, and routers generally filter these broadcasts. For connecting multiple devices, use an Ethernet hub or switch instead.

LTPE-UM-3159-02 1-5

Chapter 1: Overview September 25, 2006

In a remotely managed configuration, an external modem must be connected to the EMU-830 front panel V.24 (RS-232) console port. If enabled, alarm conditions cause ASCII messages to be transmitte d autonomously over the dial-up network. These messages can be displayed on a monitor or sent directly to a printer. This provides the network operator immediate notification of problems. The operator can then initiate a remote TAO session with the local shelf to further diagnose and correct the problem.

The EMU-830 and the DSL card firmware can be easily upgraded using the Upload utility from the T AO Main menu. This utility uses TFTP and Xmodem protocols.

A proprietary software download protocol per mits firmware to be downloaded to any unit (EMU or DSL line card) in a multishelf T AO network. This protocol is supported by a special ADC a pplication program tha t can run on a PC. The PC connects to the front panel RS-232 V.24 console port of one of the EMUs in the network.

Note: The Multishelf T AO firmware and SNMP age nt are factory loaded on all EMU-830 management units.

SNMP

SNMP (Simple Network Management Protocol) is an application layer protocol of the Internet suite of proto cols, commonly referred to as TCP/IP (after the two core protocols⎯Transmission Control Protocol and Internet Protocol), and is designed to be an "open" (non-proprietary) network management technolog y capa ble of managing internetworking equipment from multiple vendors. SNMP is formally specified in a series of related RFC (Request For Comment) documents from the Internet Engineering Task Force (IETF). The WorldDSL EMU-830 implements SNMP version 1. Communications standards supported in Version 1 of the SNMP standard include IP, User Datagram Protocol (UDP), Internet Control Message Protocol (ICMP), and Address Resolution Proto col (ARP). T wo other protocols, Boot Protocol (BOOTP) and Trivial File Transfer Protocol (TFTP), are also included to support IP address management and download of EMU-830 code over the network.

In an SNMP managed network, each WorldDSL shelf is considered a managed node and contains an SNMP software agent that resides in the EMU-830. The software agent pro vides the operating kernel, SNMP protocols, transport protocols, and management information. Multiple shelves, each of which deploy up to 16 DSL links, can be centrally managed from a single SNMP-based Network Management Station. Each DSL link consists of an LTU/ STU-C unit installed in the shelf, a remote NTU/STU-R unit, and possibly one or two mid-span doublers. Doublers are currently supported only with HDSL (e.g., LTU-804, UTU-804) line cards. A link is managed as one DSL system by SNMP.

SNMP access is provided over two types of interfaces:

• SNMP through LAN. An interface using an Ethernet port (10BASE-T) on the WorldDSL shelf that supports UDP over IP.

• SNMP through SLIP. An out-of-band (or dial-up) serial interface using the RS-232/RS-485 configurable SLIP port on the WorldDSL shelf, which supports IP over a SLIP at a maximum 19.2k baud rate.

The network of WorldDSL shelves can be managed by one or more SNMP management stations at the same time over either of the SNMP interfaces. Management can be performed through the 10BASE-T Ethernet port and the RS-232/RS-485 SLIP port simultaneously. StarGazer manages WorldDSL shelves using SNMP through LAN.

Figure 1-6 on page 1-7 shows a network of WorldDSL shelves managed by SNMP through LAN and SNMP

through SLIP.

STU-C and STU-R terminology is used with the G.SHDSL WD92xGx line cards.

WorldDSL Shelf

Simple Network Manage Protocol (SNMP) specifies how to send information between a network management station and managed devices on a network. Managed devices run a program called an agent. The agent interprets SNMP requests and responds to them. The management station communicates with the agents in the managed devices to:

• set configurations

• read configurations

• read status parameters

Management Information Bases (MIBs) define these configurations and status parameters. The Internet Engineering Task Force (IETF) specifies standard MIBs for certain types of devices, ensuring any generic SNMP application can manage them. Other vendor-specific MIBs such as those used by ADC, define the configuration, status, trap, and performance parameters unique to the WorldDSL product line.

The EMU-830 performs as a proxy agent when managing line units. Each managed device has configuration, status, and statistical information that defines its functionality and operation capabilities.

There are a total of six MIB files that define the SNMP management interface of the ADC W orldDSL pr oduct. These files should be copied into the Network Manager Client MIB Subdirectory. Once copied onto the desired drive they can be easily accessed by the Network Manager’s MIB compiler. The six MIB files are named as follows:

LTPE-UM-3159-02 1-7

Chapter 1: Overview September 25, 2006

IMPORTANT

• RFC 1213 MIB II. The Internet-standard MIB for network management of TCP/IP-based internets. It defines objects common to all devices that support SNMP. This includes objects related to generic configuration such as the device's name (sysName), objects related to the transport protocols (IP, TCP, ICMP, etc.), and a description of the chassis' interface ports (data p orts as well as HDSL ports).

• pgmibhd.mib (Common MIB). An enterprise MIB (that is, unique to ADC products) that defines the top-level branch structure for all ADC products including the W or ldDSL pro duct lin e.

• pgetsi.mib (ETSI Interface MIB). Enterprise MIB containing management objects for the shelf common equipment (chassis and EMU-830) and DSL circuit elements (LTUs/STU-Cs, NTUs/STU-Rs, doublers), excluding DSL performance related objects which are contain ed in the DSL MIB. Examples include the EMU-830 LED status (emuLedSt atus), an LTU/STU-C V.35 port data rate (ltuDataPrtTimeSlots), and PTM managed items.

• pghdsl.mib (DSL MIB). Enterprise MIB containing objects related to the performance of the DSL links, such as 15-minute and 24-hour performance history.

• pgagtmib.mib (SNMP Agent MIB). MIB containing management objects to control and configure the operation of the IP and SNMP parameters. Examples include the EMU IP address, boot and image mode, and trap receiver setup.

• pgetsitr.mib (ETSI SNMP Trap MIB). MIB containing a subset of the RFC 1215 common traps as well as ADC enterprise traps (see “Traps” below for details).

These MIB files must be used with the management unit software release.

TRAPS

Traps are autonom ous, inter rup t-d rive n messages sent from a managed node (shelf) to a management station to indicate the occurrence of an extraordinary event (such as alarms or a link going down) or a configuration change (such as changes in alarm severity settings, circuit IDs, or loopback modes). When an eve nt occurs, the shelf sends a trap to the management station, which polls the shelf to determine the nature of the event. Circuit Name is also included in the trap.

A managed node (shelf) can be configured to send trap s to up to three trap receiver s (that is, management stations). The WorldDSL traps are listed in Table 1-2.

T a ble 1-2 . W orldDSL Traps

Traps Definition

Cold Start MIB II standard trap indicating that the EMU-830 has come on-line. Authentication failure MIB II standard trap indicating that the agent received an SNMP message with

an improper community string. For example, an SNMP-managed device assigned to the community “ETSI” receives a message for a device in the “HGIS” community.

Link up/link down MIB II standard trap indicating a loss of signal condition at one of the

transmission interfaces (E1 or DSL).

DSL circuit alarm ADC enterprise trap sent at the occurrence of an alarm condition on an DSL

circuit if that alarm is of a greater severity than any existing alarms on the same circuit. Separate trap messages are sent for each DSL circuit in the shelf.

Traps Definition

Power supply failure Enterprise trap that indicates the failure of a -48 V shelf power supply input. Multiple DSL loops down Enterprise trap used to indicate when the programmable threshold of the

number of downed DSL loops in the shelf has been exceeded.

System configuration change

Line unit configuration change

Enterprise trap that signals when a change has occurred in the physical configuration of the system, such as the insertion or removal of LTUs/STU-Cs.

Enterprise trap that signals when a change has occurred in the configur ation of a line unit (includes alarm severity settings, circuit IDs, and loopback modes).

BOOTP AND TFTP PROTOCOLS

BOOTP is a UDP/IP-based protocol that allows the EMU-830 to configure itself dynamically without supervision. BOOTP provides a means for the EMU-830 to learn its protocol configuration, including:

• Local IP address and subnet mask

• Boot Server IP address

• Name of image file to be loaded into memory and executed

• Default router addresses

The BOOTP and TFTP protocols included with the EMU agent software facilitate these methods of software loading and network configuration.

The EMU can be configured to learn its protocol configuration at reset from the network (by sending a BOOTP broadcast message that is recognized by the BOOTP server) or from the NVRAM on the EMU. BOOTP provides a simple means of unit configuration. It also allows the network administrator to dynamically allocate the IP address for the EMU.

The EMU can also be configured to know where it should get its operational code (image file): either from the BOOTP server using TFTP or from the flash RAM on the EMU. This allows the EMU to always download the most recent image file at power-on or reset, and it lets the netw ork administrator keep the image file in a sing le location for use by all the WorldDSL shelves.

XMODEM PROTOCOL

The Xmodem protocol permits software to be downloaded to any EMU or line unit (local or remote) from a PC connected to the EMU front panel V.24 (RS-232) console port.

Associated Upload menus and screens allow selection of any shelf in the network and the EMU o r any line unit in the shelf as the upload target.

The EMU and each line unit is reset and runs the new code following the software download.

Do not abort the download procedure when an XModem transfer is in progress.

ALARMS

The EMU-830 constantly monitors each of the DSL cards for alarm conditions. When so configured, the EMU-830 provides autonomous dial-out reporting of alarms to remote management stations and printers (see “Autonomous

Dial-out Alarm Reporting” on page 1-10). The EMU-830 List 6A monitors the external 2 MHz clock supplied to the

shelf (see “External Shelf Clock Backup Circuit” on page 1-11). The alarm status is reported in several ways: alar m LEDs, alarm relays, terminal scree ns, SNMP trap s, and dial-out

reporting. DSL card alarms can be specified as major, minor, or disabled. Shelf alarms can be specified as major, minor, critical, or disabled. A major alarm is asserted when an alarm condition occurs in a card or shelf tha t is specified as major. A minor alarm is asserted when an alarm condition occurs in an DSL card or shelf that is specified as minor. Only shelf alarms can be classified as critical. A critical alarm is asserted when any shelf alarm occurs that is specified as critical. Use the TAO Main menu to login to an DSL circuit to configure the DSL card alarms (see “Config Menu” on page 3-8).

Six alarm relays are provided for use with external alarm indicators such as lights or buzzers. Each relay is a form C type which provides three contacts: Common, Normally Open, and Normally Closed. An alarm relay diagram is shown in Figure 1-7.

Normally Closed

Normally Open

Common

Figure 1-7. EMU-830 Alarm Relay Diagram

The six alarm relays are:

1. Critical Visual

2. Critical Audible

3. Major Visual

4. Major Audible

5. Minor Visual

6. Minor Audible

Additionally, a System ID relay is activated when any minor, major, or critical alarm is active in the shelf. The Critical Visual and Critical Audible alarm relays and the System ID relay operate in the fail-safe mode. That is,

when power is lost to the EMU-830, the Common contact connects to the Normally Open contact. The ACO (Alarm Cut-Off) function is used to retire active alarms by resetting the minor, major, and critical alarm

relays (both visual and audible). The Shelf Alarms menu (pageC-16) can be used to program which alarm relays will and will not be retired when ACO is engaged. ACO can be activated by pressing the front panel ACO switch or by connecting the external ACO input (pin 25 of the Alarm connector on a shel f) to ground. ACO is deactivated when there are no alarms or when a new alarm occurs.

AUTONOMOUS DIAL-OUT ALARM REPORTING

When connected through a modem to a dedicated telephone line, the EMU-830 can dial-out to a remote management station or printer to autonomously re port DSL card a nd shelf alar ms. For the EMU-830 to p erform this function, you must first configure the EMU Modem Parameters, set the severity of the Shelf Alarms, and enable the Remote Alarm Reporting option (see page C-14 through page C-17).

September 25, 2006 Chapter 1: Overview

EXTERNAL SHELF CLOCK BACKUP CIRCUIT

The EMU-830 List 6A includes a backup circuit for the 2.048 MHz external shelf clock. This circuit will continue to provide a 2.048 MHz clock to the DSL cards in the event the 2.048 MHz external shelf clock is lost. The software reports the status of this circuit and allows the user to set th e seve rity of the alar m ge nerated when the clock is lost. A block diagram of the clock backup circuit is shown in Figure 1-8 on page 1-11.

Under normal operation the external shelf clock and the backup circuit synchronize their respective clocks through the EMUs phase-locked loop (PLL) device. In the event the external shelf clock is lost, the oscillator in the backup circuit will continue to supply the 2.048 MHz clock. A Loss of External Clock alarm is reported to the management station.

INSTALLATION

This section describes the procedures for installing the EMU-830.

Note: Each shelf in a Multishelf TAO network must have an EMU-83 0 management unit inst alled.

Inserting and removing the EMU-830 from a shelf will not affect the operation of the DSL cards installed in the shelf. An EMU-830 failure will not affect the operation of the DSL cards installed in the shelf.

EMU JUMPER SETTINGS

EMU-830s are jumper configurable for an RS-232 or RS- 485 SLIP port interface. EMUs have an RS-232 factory setting.

If you use the SLIP port to manage a shelf or shelves, you must configure the SLIP port interface before installing the EMU-830. Do one of the following:

• For an RS-232 SLIP port interface, install the jumper on two-pin header connector P6 (Figure 2-1). This is the factory default setting. Set the SLIP port baud rate as instructed in “Configure SNMP Operation Over SLIP” on

page 3-10.

• For an RS-485 SLIP port interface, remove the jumper from two-pin header connector P6 (Figure 2-1). Set the SLIP port baud rate as instructed in “Configure SNMP Operation Over SLIP” on page 3-10.

MULTISHELF CABLE CONNECTIONS

Note: Multishelf networks cannot be connected through a router because the local shelf uses UDP-

broadcast messages as a mechanism to automatically discover other shelves in the network, and routers generally filter these broadcasts. A multishelf network is limited to 32 shelves.

To connect the shelves using the 10BASE-T Ethernet connectors (Figure 2-4):

Step Action

1 Plug an RJ-45 cable into the 10BASE-T connector at the rear of each shelf. 2 Plug the other end of the RJ-45 cables into the hub/switch connecting the shelves.

Note: The length of each RJ-45 cable cannot exceed 100 meters (328 feet).

REMOTE TERMINAL AND LOCAL SHELF MODEM CONNECTIONS

Remote management of one or more Multishelf TAO sites over a telephone network requires the connection of a modem to the remote management station and to the EMU residing in the local shelf of each site. Once connected, the remote management station can access the console menus of one or more multishelf networks to configure, monitor , and test their EMU and DSL circuits. The local shelf can autonomously report alarms to the management station through the modem attached to its EMU.

Management Station Internal Modem

An internal modem card provides an RJ-11 jack at the back panel of the management station. If the management station has an internal modem, plug your phone-line connector into the RJ-11 jack and turn on the management station. Set up the internal modem for 19,200 baud. If you experience problems, refer to your modem or management station user manual.

Management Station External Modem

An external modem requires a serial cable, an external power source, and an unused serial port on the back of the management station.

To connect an external modem to your management station serial port:

Step Action

1 Plug a serial cable into an available serial port on the back of the management station, using a 9-to-25 pin

converter or gender changer if necessary. 2 Plug the other end of the cable into the serial port on the back of the modem. 3 At the back of the modem, plug the telephone line into the RJ-11 port labeled "LINE" or "TELCO". 4 Plug the modem into an external power source and turn it on, then turn on the management station. 5 Verify that the modem is responding to commands from the management station . Use a communications

program to send an AT command to the modem. The modem resp onds with the string "OK" if operation is

successful. 6 Configure the shelf modem for remote alarm reporting as instructed in “Remote Alarm Reporting” on

page 3-17.

7 If you experience problems refer to the modem or management station user manual.

Local Shelf Modem for Multishelf TAO

The local shelf in a remotely managed Multishelf TAO network uses an external modem connected to its EMU console port. The modem, however, must be programmed with a PC before it can be connected to the EMU (the EMU residing in the shelf cannot control a modem as a PC can).

Note: The shelf modem can be attached to the EMU in any sh elf. The shelf with the modem att ached is the

“local” shelf. If managing a shelf through its SLIP port, see “Shelf Modem for SLIP Operation” on p age 2-9.

LTPE-UM-3159-02 2-7

Chapter 2: Installation September 25, 2006

Step Action

1 Connect the shelf modem to the PC and verify that it is in working condition as described in the preceding

section, “Management Station External Modem.” 2 Use a communications program to send the following initialization string to the modem:

AT&F

This string resets the modem to its original factory configuration and clears any previous programming

that can conflict with the communication between the modem and the EMU. 3 Send the following configuration string to the modem:

ATE0Q1S0=1&K0Y0&W0

This string configures the modem to operate properly with the EMU. The commands in this configuration

string are as follows:

AT The command prefix indicating an AT command E0 Do not echo input characters Q1 Do not return result codes S0=1 Answer the phone after the first ring &K0 Disable flow control Y0 Use profile 0 as the power-up configuration &W0 Store current configuration as profile 0

Note: The shelf modem does not respond with an "OK" when you enter the above string. This

string disables all response codes and echo capability in the modem. The response codes are not used by the EMU. When the modem is properly configured, the Auto Answer (AA) lamp on the modem panel lights, indicating that the modem is waiting for the phone to ring to answer an incoming call from the management station PC.

SHELF MODEM FOR SLIP OPERATION

One or more shelves can be remotely managed by connecting an external modem to the RS-232/RS-48 5 SLIP port. However, whe n managed through the SLIP port, each shel f must be assigned a unique IP address (only o ne shelf is accessed with each dial-up connection). Figure 1-6 on page 1-7 show WorldDSL shelves managed by SNMP through SLIP.

Note: See “EMU Jumper Settings” on page 2-1 for RS-232/RS-485 SLIP port configuration.

This procedure requires the use of a 25-wire straight-through cable, with a ma le DB-25 connector on each

end of the cable (see Figure 2-8 on page 2-10).

To connect an external modem to the RS-232/RS-485 SLIP port:

Step Action

1 Connect one end of the 25-wire cable to the RS-232/RS-485 (SLIP) connector on the EMS shelf. 2 Connect the other end of the cable to a standard modem. 3 If the modem has configuration switches or jumpers, set the switches or jumpers for factory default

operation. Refer to the modem user manual for more information. 4 At the back of the modem, plug a dedicated telephone line into the RJ-11 port labeled LINE or TELCO. 5 Plug the modem into an external power source and turn it on.

Shelf Alarms

The state of shelf and DSL alarms is continuously updated in the Main Menu screen. There are two possible shelf alarms, both of which can be classified as Minor, Major, Critical, or Disabled:

• Power Supply Failure (POWER A or POWER B). This is a loss of -48 Vdc power at input A or B on the rear of the shelf.

• DSL alarm (HDSL LINKS). This alarm indicates when a programmable number of DSL loops in the shelf are down. A loop is considered to be one copper pair. A shelf containing 16 DSL cards has either 16 loops (singlepair) or 32 loops (two-pair). If the signal at the application interface of a one- or two-pair HDSL card is lost, both HDSL loops in that circuit are considered down.

HDSL/G.SHDSL Line Unit Status

The HDSL Line Unit Status field displays the status for each of 16 circuits that can be managed by the EMU-830. For each circuit, the most severe active alarm is displayed. For each slot, the basic status o f the circuit is displayed. The status conditions for each slot are described in Table 3-3 on page 3-6. Table 3-4 on page 3-6 lists the DSL circuit alarms in order of severity .

Logging in to an HDSL/G.SHDSL Circuit

Logging into the console menu of an DSL card from this screen is equivalent to connecting a VT100 terminal or PC directly to the card’s craft port. It permit s you to change configur ations, monitor performance, and test circuits of DSL cards from the management station. See “Logging into DSL Circuits” on page 3-7.

COMPATIBILITY

The EMU-830 is compatible with HDSL, G.SHDLS cards, desktop units, doublers (regenerators), and exchange office management shelves in the WorldDSL product line. Universal Termination Units (UTUs) can be configured as LTUs or NTUs. WD92xGx can be configured as STU-Cs or STU-Rs. Typically the LTU/STU-C DSL cards are installed in the management shelf and the NTU/STU-R DSL cards are deployed at the remote site. You can, however, use either an LTU/STU-C or NTU/STU-R DSL card in a shelf as the EMU-830 allows terminal access to both types of DSL cards when installed in a shelf. Alarm management, however, is only performed on LTU/STU-C cards and their attached circuit elements.

The following is an abbreviated list of EMU-compatible WorldDSL products.

• Shelves: All EMS-83x List 2

• HDSL Cards: All LTU-80x List x, UTU-80x Lx

• Universal Termination Units: All UTU-9xx

• Integrated Desktop Units: All ETU-8xx and ETU-9xx

• Doublers (regenerators): All EDU-840 List x

• G.SHDSL Cards: WD92xGx line cards
