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.
Stinger Hardware Installation Guide 1-3Introduction 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.
Table 1-1. Stinger trunk modules port speeds and capacity
LIM Port Speed Port Capacity
DS3 (ATM) 44.738 Mbps 2 active DS3 ports, 2 backup DS3 ports.
Up to 4 active ports per system.
OC-3c/STM-1 155.52 Mbps 2 OC-3c/STM-1 ports. Up to 4 ports per
(optical) system.
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.
1-4 Stinger Hardware Installation GuideIntroduction 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.

Stinger Hardware Installation Guide 1-5Introduction 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.
