Stinger Intended Use
The Stinger unit can be used as a DSL ATM switch that provides DSL connections for
individual users. Users connect to the unit over DSL lines supported by line interface
modules (LIMs) that are installed in the Stinger unit. The Stinger FS+ unit can be
equipped with an IP control module to provide IP termination and routing for user
connections. The Stinger FS+ can also be equipped with specialized optical LIMs that
allow it to act as a host unit for ATM-based and IP-based Stinger Compact Remote
units.
Every Stinger unit contains a special control module that controls the operation of
the unit. Two control modules can be installed in a redundant arrangement, with one
active and primary, and the other a spare. The physical interfaces on the unit provide
DSL, ATM, or IP network connections to digital lines. A serial or Ethernet LAN
connection can be used for configuration and administration. Units equipped with
revision 2, or later, control modules also provide interfaces for monitoring the alarm
status of other devices, and an optional internal modem.

DSL lines supporting several DSL protocols. LIMs are available to support the
