                      Monospace text Represents text that appears on your computer’s screen, or that could
                                     appear on your computer’s screen.
                      Boldface               Represents characters that you enter exactly as shown (unless the
                      mono-space             characters are also in italics—see Italics, below). If you could
                      text                   enter the characters but are not specifically instructed to, they do not
                                             appear in boldface.
                      Italics                Represent variable information. Do not enter the words themselves in
                                             the command. Enter the information they represent. In ordinary text,
                                             italics are used for titles of publications, for some terms that would
                                             otherwise be in quotation marks, and to show emphasis.
                      []                     Square brackets indicate an optional argument you might add to a
                                             command. To include such an argument, type only the information
                                             inside the brackets. Do not type the brackets unless they appear in bold
                                             type.
                      |                      Separates command choices that are mutually exclusive.
                      >                      Points to the next level in the path to a parameter or menu item. The
                                             item that follows the angle bracket is one of the options that appears
                                             when you select the item that precedes the angle bracket.

Hardware components
                   The Stinger chasis consists of the following major hardware components:
                   •   2 control modules (CM), one active and one standby, which control the DSLAM’s
                       functions and contain the ATM switch fabric that interconnects all the Stinger modules.
                   •   Trunk modules (TM), DS3 or OC3, which connect to an ATM device such as a
                       DSL Terminator or a BSTDX.
                   •   14 DSL line interface modules (LIMs), ADSL or SDSL, which connect to subscriber
                       lines.
                   •   14 line protection modules, which provide the access to the local loop as well as circuit
                       protection for LIMs.
                   •   Dual power filters.
                   •   Cooling fans.
                   •   Air filter.

                   Modules in the DSLAM connect to each other via the midplane. The control modules control
                   the DSLAM and interact with the trunk modules and the line interface modules. The TMs
                   provide the interface to the ATM network. The LIMs can accommodate numerous interface
                   specifications, speeds, and protocols as they process subscriber traffic. Each LIM connects to
                   the local loop via an LPM. The LPMs contain the connections for network cables and provide
                   a hardware bridge between the physical network and the LIMs. Figure 1-1 illustrates the traffic
                   flow in the Stinger.

Control modules
                     The Control Module (CM) is based on a standard RISC microprocessor and provides basic
                     DSLAM management and signaling. The CM has direct access to a redundant ATM switching
                     fabric via a SAR. The ATM switch is implemented in ASIC and provides a 64 x 64
                     non-blocking, scheduled crossbar interconnecting all the module slots and CM slots.

                     The CM also contains two management interfaces: an RS232 serial port (for access to
                     out-of-band management) and a 10/100BaseT auto-sensing Ethernet port. Additionally a
                     PCMCIA slot is provided for general maintenance, such as updating code or backup
                     configuration storage.

Introduction to the Stinger
Stinger redundancy

                   Installations with high-reliability networking requirements may require a second CM to make
                   the DSLAM redundant. In the event of a primary CM failure, the redundant CM automatically
                   becomes active and takes over control of the system. This avoids serious service disruption on
                   the network.

                   The CMs communicate with and control the LIMs and the TMs over a control bus.

Line interface modules
                   The Stinger contains 14 slots for LIMs with an ATM switching capacity of approximately
                   1.6 Gbps. You can install any mixture of DSL LIMs. Each LIM contains 48 SDSL ports or 12
                   ADSL ports and is connected directly to the midplane. LIMs perform physical data link, ATM
                   switching, and multiplexing operations on user links.

                   The LIMs connect to the network via a midplane connection to the LPMs in the rear of the
                   unit.

Line protection modules
                   Line protection modules are located at the rear of the Stinger. Each LPM connects the LIMs to
                   the subscriber loop via 50 pin telco connectors. The LPMs contain the necessary line
                   protection logic and a set of relays for redundancy switching. The active CM controls the
                   redundancy switchover. The protected circuits are fed to the LIM card directly in front of the
                   LPM (under normal conditions) or to the spare LIM (when a redundant switchover has
                   occurred). All protection circuitry is connected to chassis ground.

Trunk modules
                   Trunk modules aggregate traffic received from DSL subscribers and sends it to a terminating
                   device such as DSL Terminator or a CBX 500. Interfaces include DS3, STS-3c and STM1.

                   Table 1-1 lists the trunk modules supported on the Stinger and identifies the port speed and
                   port capacity for each module type.

                    OC-3c/STM-1            155.52 Mbps                2 OC-3c/STM-1 ports. Up to 4 ports per

Stinger redundancy
                   Stinger redundancy and recovery consists of both hardware and software mechanisms that
                   enable the DSLAM to continue operation after certain types of failure.

Introduction to the Stinger
                                                                                           Stinger redundancy

CM redundancy
                     The Stinger CMs provide redundant CMs for high reliability networking requirements.
                     Although the unit can operate with a single CM, redundant operation is recommended. The
                     primary CM controls the unit, performs ATM switching and the associated operations, such as
                     traffic policing and shaping, and handles traffic to and from the LIMs and TMs. Status LEDs
                     on the CM front panel indicate which of the modules is the primary CM.

                     The secondary or standby CM monitors the primary CM using a heartbeat protocol, updates its
                     own repositories of code and configuration settings whenever the primary CM is updated, and
                     immediately takes over operations if the primary CM fails.

Power redundancy
                     The Stinger has two -48V DC inputs. The Stinger routes the voltage to a DC-DC converter on
                     each card which provides the necessary DC voltages and power for the card. A power
                     component failure is isolated to a single card.

LIM redundancy
                     If CM detects failure of a LIM, it can switch the traffic from the associated LPM to a single
                     redundant path on the mid-plane. This is accomplished using an Interface Redundancy Module
                     (IRM). The IRM is installed in place of a standard LPM in the back of the unit and provides a
                     direct path from the mid-plane to the spare LIM, when directed to do so by the CM. Figure 1-2
                     illustrates the traffic flow in the Stinger when LIM redundancy is activated.

Introduction to the Stinger
Stinger redundancy

Trunk redundancy
                   TMs support port-level redundancy. For TMs with copper interfaces, such as the DS3 module,
                   administrators can configure redundant connections via the backup connectors on the TM. If
                   the primary or port fails, either due to a failure to boot up or because it is in a fault state, the
                   secondary port takes over.

                   For TMs with optical interfaces, such as the OC3 module, administrators can configure
                   redundant connections using an external fiber switch. When the switch detects a failure in the
                   fiber interface, it switches over to the standby port.

                          of the product and to protect it from overheating, these slots and openings must not be
                          blocked or covered. Installation without sufficient airflow can be unsafe.
                     7    Mounting of the equipment in the rack should be such that a hazardous condition is not
                          achieved due to uneven mechanical loading. The rack should safely support the combined
                          weight of all equipment. This product weighs 160 lbs (72.57 kg).
                     8    The power source has to be adequately rated to assure safe operation of the equipment.
                          The building installation and or power source shall provide overload protection.
                     9    Protective earth (PE) connection is essential before connecting to supply and
                          telecommunication network to ensure safe operation. Use wire sizes for grounding in
                          accordance with national standards and specifications as described in IEC 60950.
                          For models with dc power inputs, the protective earth connection shall be established
                          using the dedicated earthing terminal marked with the PE symbol or if provided, the
                          earthing pin of the input terminal block.
                     10 Models with dc power inputs shall be connected to a -48V dc supply source that is
                        electrically isolated from the ac source in accordance with UL1950, C22.2 No. 950 and

                     damaged” on page D-2.

                     Due to the large size and weight of a fully configured unit, Lucent recommends moving the
                     unit to the installation site before unpacking it from the shipping carton.

    !                Warning: A fully configured Stinger unit weighs up to 160 pounds. To avoid potential injury,
                     use a hand lift for moving or rack-mounting the unit.

                     To unpack the unit:
                     1    Open the carton and remove all enclosed packing materials. Save the packing materials in
                          case you need to repack the unit later.
                     2    Check the contents of the carton against the items listed on the packing slip.
                     3    Using a #2 Phillips screwdriver, remove the screws from the L-brackets on the delivery
                          pallet.
                     4    Carefully remove the unit from the pallet.

                     The middle two slots in the front of the Stinger (slots 8 and 9) are reserved for the control
                     modules; they cannot be used for LIMs. Slots that are not occupied by LIM modules are masked
                     with blank covers to ensure proper air flow through the unit.

Checking the TMs and LPMs
                     Figure 3-2 shows the back of the Stinger chassis.
