The Stinger® Compact Remote ATM DSLAM Getting Started Guide
Introduction to the Stinger Compact Remote ATM DSLAM
Stinger Compact Remote ATM DSLAM hardware
Each of the replaceable modular components support different capabilities.
■
The standard control module—The standard control module provides a TAOS
management interface for configuration and management of the unit. It controls
the operation of the Stinger Compact Remote ATM DSLAM, and manages traffic
through the unit. It also maintains information about the configuration of the
components and lines associated with the unit. The control module does not
provide an interface with sufficient bandwidth to provide an upstream
connection for end-user traffic. Support is provided for three models of the
standard control module; the STGR-CM-A and STGR-CM-A2 control modules
which are each equipped with a 10/100 Ethernet port for connection to a
management network, and the STGR-CM-B control module with an integrated
modem.
■
The IP2000 control module—The IP2000 module provides a TAOS management
interface for configuration and management of the unit. It controls the operation
of the Stinger Compact Remote ATM DSLAM, manages traffic through the unit,
and maintains information about the configuration of the unit. It also provides a
gigabit Ethernet interface that supports an upstream connection for end-user
traffic.
■
The COP—The COP is a specialized module that controls the Stinger Compact
Remote ATM DSLAM. It contains controller hardware found in control modules
on larger Stinger units but does not provide a local management interface for
system configuration. An internal daughter card supports a155Mbps optical
interface that links the Stinger Compact Remote ATM DSLAM unit to a
specialized optical line interface module (OLIM) installed in a host Stinger unit.
End-user traffic and a control link for management of the Compact Remote ATM
DSLAM unit are both carried over this connection.
■
ADSL/ADSL2+ LIMs and RLIMs—ADSL Line interface modules (LIMs) provide
the internal interfaces that are configured to provide service for individual DSL
subscriber lines. LIMs installed in a Stinger CR ATM DSLAM unit that is
configured for hosted operation 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.
!
Caution
Because of the heat dissipation characteristics, green enclosures
equipped with an IP2000 module must not contain more than two sets of
LIM/LPM modules in locations where ambient temperatures exceed 104°F
(+40°C).
■
SHDSL LIMs—SHDSL Line interface modules (LIMs) provide the internal
interfaces that are configured to provide service for individual DSL subscriber
lines.
