Depending on bandwidth requirements, a specially designed trunk module that
supports OC3/STM1, DS3, T1, or E1 service can be installed in the Stinger MRT
chassis. Each Stinger MRT chassis is equipped with a pair of STS-3 connectors that
can forward (cascade) traffic through multiple Stinger MRT units in a common
location to a single unit with a trunk module.
Stinger® MRT Getting Started Guide 1-1
Introduction to the Stinger MRT
Virtual slot conventions for the Stinger MRT
Some Stinger MRT models also incorporate integrated line splitters to provide
asymmetric digital subscriber line (ASDL) and analog telephone (POTS) service over
a single pair of wires. For chassis details, including model number designations, and
line capabilities, see
Table 1-2.
Virtual slot conventions for the Stinger MRT
The highly integrated Stinger MRT 19 and Stinger MRT 23 use the same TAOS
software as larger Stinger units. In the larger Stinger units TAOS uses the physical slot
number in which modules are installed to access the parameters of those modules
and configure them. In the Stinger MRT, functions are grouped into virtual slots, so
that they can be accessed and configured by the TAOS software in a manner similar
to other Stinger models.
Table 1-1 compares the physical slot locations of modules installed in a Stinger FS
with the virtual slot locations for the same functions integrated into the Stinger MRT.
These virtual slot positions are used in examples throughout this document.

Stinger MRT models and optional products
Two models of the Stinger MRT 23 are available to support different ADSL line
lengths. The original Stinger MRT 23 was designed for field installations with short
ADSL subscriber loops. This model supports speeds up to 8.128Kbps over 24
American wire gauge (AWG, 0.25 mm²) copper facilities up to 2000 feet, and lower
speeds beyond that distance.
A newer standard-reach version of the MRT 23 supports the standard ADSL
subscriber loop length, identical to the full-sized central office version of the Stinger.
This standard-reach version supports speeds up to 8.128Kbps over 24 AWG (0.25
mm²) copper facilities up to 8000 feet in length, and lower speeds beyond that
distance.
Two models of the MRT 19 are also available. One model of the MRT 19 supports up
to 48 ADSL connections without POTS capability, and another supports up to 36
SHDSL connections.
The two versions of the Stinger MRT 23 can be ordered with different trunk modules
or software options installed for different bandwidth requirements. Trunk modules
for the Stinger MRT 19 models are ordered separately, the base chassis are supplied
with a blank faceplate covering the trunk module slot. Optional software is available

Before you choose a setup location for a Stinger MRT unit, read and follow the site
and electrical requirements defined in the Edge Access and Broadband Access Safety and Compliance Guide.
Select the setup location carefully. Keep in mind that the unit requires proper
ventilation and space for current and future cabling requirements.
Caution At least 1 inch (2.5cm) of clear space must remain on both sides of the MRT
!
chassis to ensure sufficient air flow. The Stinger MRT 23 and Stinger MRT 19 pull air
in from the right side of the chassis and exhaust air from the left side of the chassis.
A Stinger MRT can be mounted in a number of ways, depending on the space that is
available. You can rack-mount the Stinger MRT 23 chassis horizontally in an
equipment rack or outdoor cabinet with mounting rails that are 23 inches (58.42cm)
apart. You can rack-mount the Stinger MRT 19 chassis in an equipment rack or
outdoor cabinet with mounting rails that are 17.72 inches (45.0cm) apart. Optional

Preparing for the Installation
Required tools and equipment
Caution Before handling Stinger MRT components, ensure that your work area is
!
free from common plastics and that you are properly grounded with an antistatic
wrist strap, to prevent component damage from electrostatic discharge. For more
information, see
“Preventing static discharge damage” on page 2-2.
Required tools and equipment
To install and configure the Stinger MRT hardware, you need the following tools and
equipment:
■Console terminal connection to the serial (CONSOLE) port to configure the unit
■ASCII or VT100 console terminal (Internal Lucent number: ITE-6938) or
equivalent with the following setup:
–9600bps
–Direct connection
–8 data bits
–No parity
–1 stop bit
–No flow control
■RS-232 straight-through modem cable for connecting the console terminal or

■Number 2 Phillips screwdriver
■1/8-inch and 3/16-inch standard screwdrivers
■(Optional) Ethernet LAN connection for connecting the unit to the Ethernet
(Internal Lucent number for a 7-foot cable: ITE-7131, and for a 12-foot cable:
ITE-7180)
■A CLETOP fiber cleaning tool, if an OC3 trunk module is being installed
Preventing static discharge damage
Modules and semiconductor devices in general can be easily and permanently
damaged due to electrostatic discharge during installation or removal. A person
walking across a floor can generate electrostatic voltages in excess of 5000V.
Although you might not notice a discharge of less than 3500V, discharges below 100V
can damage semiconductor components.
You can destroy a component without noticing any electrostatic discharge. Because
these discharges have very little current, they are harmless to people.
To prevent damage to components from electrostatic discharge, always follow the
proper guidelines for equipment handling and storage.
Use a wrist strap
To reduce the static potential on your body by proper grounding, wear an approved
antistatic wrist strap (
while handling any Lucent device containing semiconductor components.
2-2 Stinger® MRT Getting Started Guide
Figure 2-1) when installing, removing, or handling modules, or

Figure 2-2. Wrist strap plugged into a grounding jack
If a grounding jack is not available, use an alligator clip to connect the strap to
electrical ground.
Stinger® MRT Getting Started Guide 2-3
Preparing for the Installation
Unpacking the Stinger MRT
Use the following two simple tests to verify that the wrist strap is functioning
properly:
■Measure the resistance between the wrist strap and its grounding plug. Overall
resistance between these two points must be approximately 1Megohm. If it is
not, replace the strap.
■Physically examine the strap for visible damage. If you see any damage, replace
the strap.
Remove plastics from your work area
Work areas must be kept clear of common plastics, such as the following items:
■Polystyrene packing containers
■Clear plastic bags
■Plastic drinking cups
■Food wrappers
■Clear cellophane tape
These types of common plastic materials can carry a static charge that is not easily
discharged to ground and must not make direct contact with modules or any other
solid state components.
Store components properly
Protect modules immediately after removal from a chassis by placing them in their
original factory packing materials. Storage in approved antistatic packaging is
acceptable when factory packaging is unavailable.
Caution Never place unprotected modules directly on ungrounded metal shelving
!
or on ungrounded carts without insulating surfaces.
Unpacking the Stinger MRT
The Stinger unit is delivered in a protective shipping carton, with the ordered trunk
module installed.
Before you remove the Stinger unit from the shipping carton, check for damage. If
you see any damage, follow the instructions described in your product warranty.
To unpack the unit:
1Open the carton and remove all enclosed packing materials. Save the packing
materials in case you need to repack the unit later.
2Carefully remove the unit from the shipping carton.
3Verify that the contents of the carton match the items listed on the packing slip.
Verifying the hardware configuration
Stinger MRT units have an integrated design that includes a -48Vdc power supply
and all the capabilities associated with control modules, line interface modules
(LIMs), and line protection modules (LPMs) of other Stinger models. Trunk modules
designed for use in a Stinger MRT can be installed to support different types of trunk
2-4 Stinger® MRT Getting Started Guide
connections. The trunk module ordered with the unit is installed prior to shipment.
Check the unit to verify that it is configured as ordered and to identify the connection
points for power and data. The cable connectors and power supply inlets are located
at the front of the chassis.
Note The system software configuration is stored in onboard nonvolatile RAM
(NVRAM).

Verifying the hardware configuration
STS-3 cascading connectors
Each Stinger MRT and MRT-2 unit is equipped with a pair of STS-3 connectors. These
connectors can connect multiple units that are installed in a single location. The
STS-3 connectors allow creation of ATM links to carry traffic from a Stinger MRT or
MRT-2 unit that is not equipped with a trunk module to a unit that is equipped with
a trunk module. Several units can be linked together so that traffic can be combined
in a cascading fashion, until it reaches a single unit with a line to the distant ATM
switch. This can be managed in two ways.
■Configured ATM connections—ATM connections can be configured to so that
traffic from all the units is combined in a cascading fashion, until it reaches the
unit with the link to the remote ATM switch.
■Hosted (master/slave) connections—It is also possible for the unit with the link to
the remote ATM switch to act as the host (master) unit for the other MRT or
MRT-2 units. These other units become hosted (slave) units. All connections
between units are configured automatically by the TAOS software, and all
administration for the group is performed on the TAOS interface of the master
unit. For details about this type of configuration, see
Operation of Cascaded Stinger MRT units.”
Note Lucent Technologies recommends connecting no more than three Stinger MRT
or MRT-2 units in cascading fashion or five units in a hosted system configuration.
Although the units can support longer distances, Lucent recommends that cascading
or hosted units be no more than 10 feet (3.05m) from each other.
Appendix B, “Hosted
Shelf ID switch
The shelf ID switch is used to designate the shelf number that will be associated with
the chassis in a hosted system configuration. See,
on page B-4 for details.
Trunk module location
A Stinger MRT can contain a trunk module that supports OC3/STM1, DS3, T1, or E1
service. Each trunk module supports connection to either optical or copper media,
depending on the type of module supplied. There is a single physical slot on the front
of the Stinger MRT for installation of the trunk module. This slot is referred to by the
operating system as virtual slot
Caution Do not remove or replace the trunk module while the Stinger MRT unit is
!
operating. Be sure to remove power from the unit before removing or replacing a
trunk module.
Note Individual trunk modules are not interchangeable between the Stinger MRT
23 and Stinger MRT 19. For detailed information about a specific trunk module, see
the chapter in this guide related to that module.
Figure 2-5 and Figure 2-6 show the location of the trunk module in the front of a
Stinger MRT 23 and Stinger MRT 19 chassis. An OC3-ATM trunk module is shown
