Introduction to the Stinger
Compact Remote
Stinger Compact Remote overview
The Stinger Compact Remote (CR) is a temperature-hardened optical network unit
(ONU). This ONU can be installed outdoors, close to subscriber locations, to extend
the reach of host Stinger units in a central office. Subscriber DSL lines are physically
terminated on the Compact Remote unit which is connected to a host Stinger unit in
the central office by an optical link. These DSL lines appear as ATM connection
endpoints within the TAOS management interface of the host Stinger in the central
office. The link between the host Stinger unit and a hosted Stinger CR unit is
transparent to these ATM connections.
The Stinger Compact Remote consists of a card-cage chassis that accommodates
circuit packs, a cooling unit, and a power supply. This chassis and its components are
installed in an integrated outdoor enclosure that is pre-wired with protection blocks
for the copper facilities. This integrated enclosure provides an operating environment
that can range between -40°F (-40°C) and 114.8°F (+46°C). For more environmental
information, see “Operating environment”on page F-3.
The front of the Stinger CR chassis has seven vertical slots for designated plug-in
components and two larger bays for the cooling module and power supply. The
vertical slots accept up to three sets of subscriber line circuit packs and one control
and optics pack (COP). Each subscriber line circuit pack consists of a remote line
interface module (RLIM), and a line protection module (LPM). A cooling unit is
installed in a bay at the top of the chassis, and a power supply is installed in a bay at
the bottom of the chassis. (See Figure 1-1 on page 1-3.)
The plug-in components for the Stinger Compact Remote support the following
functions:
■The COP—The COP is a specialized plug-in unit that controls the Stinger
Compact Remote. It contains the controller hardware found in control modules
on larger Stinger units and an internal daughter card that supports an OC-3
STM-1 interface. The OC-3 STM-1 interface links the Stinger Compact Remote

1-2 Stinger®Compact Remote Installation and Configuration Guide
Introduction to the Stinger Compact Remote
The Stinger CR chassis
unit to a specialized optical line interface module (OLIM) installed in a host
Stinger unit. Network traffic and a control link for the Compact Remote unit are
carried over this connection.
■RLIMs—Line interface modules (LIMs) installed in a Stinger CR unit are referred
to as remote line interface modules (RLIMs), because they are accessed remotely
through the management interface of the host unit to configure and maintain the
DSL subscriber lines that they support.
■Line protection modules (LPMs)—The LPMs provide protection for the unit from
transient conditions on the subscriber line. LPMs designed for the Stinger CR also
contain integrated splitters that connect to analog voice facilities. These splitters
allow analog voice service from the central office, and DSL service from the
Stinger, to be delivered to the subscriber on the same pair of wires.
■Cooling unit—The cooling unit contains a fan and electronics to monitor its
operation. This fan maintains airflow to distribute heat produced by the Stinger
CR, so that it can be efficiently dissipated. The cooling unit also provides a power
connection for a ventilation fan, mounted in the side of the enclosure.
■Power supply—The power supply converts +190Vdc and -190Vdc provided from
the central office into -48Vdc needed to operate the Stinger CR.
The Stinger CR chassis
Like larger Stinger units, the Stinger CR uses replaceable components that are
installed in slots in the front of the chassis. Unlike larger Stinger units, the Stinger CR
has slots for fewer circuit packs and is temperature hardened for outdoor installation
in its integrated enclosure. It has a smaller single-fan cooling unit installed in the top
of the chassis and a removable power supply installed in the bottom of the chassis.
The significant physical features of the Stinger CR chassis are illustrated in Figure 1-1.
