A T1 or E1 LIM is also available to provide up to 8 or 24 DS1 or E1 lines for traffic
exiting the network (egress traffic), when the DS3, E3, or OC3 bandwidth of a trunk
module is not needed.
For specific information about LIM configuration, see the module guide for the
desired LIM.
Two types of optical LIMs are designed to provide links to Stinger Compact Remote
units. For information about configuring these LIMs and the links they provide, see
the
Stinger Compact Remote ATM DSLAM Getting Started Guide
, or the
Stinger Compact
Remote IP DSLAM Getting Started Guide
.
Trunk module configuration
A Stinger unit can support up to two trunk modules, which can be OC3-ATM,
OC12-ATM, DS3-ATM, or E3-ATM trunk modules. You can set up the unit to use the
full trunk-side bandwidth actively, or you can designate one or two of the trunk ports
as spares, to be used only if another trunk port fails.
Each trunk module can connect the Stinger unit to another ATM switch. The line
configuration includes settings that must match between the local and far-end switch
interfaces.
For specific information about trunk module configuration, see the module guide for
the desired trunk module.
System clocking modes
The Stinger unit requires a clock source for its timing subsystem. By default, it uses a
built-in 8kHz clock on the primary or single control module as its timing source. You
can configure the system to take its clock source from a trunk port or from an
external building interoffice timing source (BITS) clock connected to the Stinger
alarm relay.
For detailed configuration information, see “Configuring system clocking” on
page 5-19.
Stinger management features
To enable you to configure the system and monitor its activity, Stinger units support
profiles, commands, and status windows in the command-line interface. Stinger units
also support SNMP management, RADIUS profiles, and the ability to upload (back
up) and download software and configuration files over TFTP or serial connections.
A Stinger system provides several permission levels to control the management and
configuration functions that are accessible in the command-line interface. For
information about User profiles and other management features, see the
Stinger
Administration Guide

Using the command-line interface
The Stinger command-line interface provides access to commands, profiles, and
status windows. You must use the command-line interface to provide the initial
