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 bandwidth of a DS3, E3, or OC3 trunk
module is not needed.
For specific information about LIM configuration, see the module guide for the
desired LIM.
Trunk module configuration
The Stinger MS+ unit supports a single trunk module or TRAM modules. Trunk
modules with OC3-ATM, DS3-ATM, or E3-ATM interfaces are supported. OC3 TRAM
modules with DS3, E3, or only OC3 interfaces are also supported. 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.
The 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 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 unit.
For detailed configuration information, see “Configuring system clocking” on
page 5-14.
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
.
For an introduction to the command-line interface and its shortcuts, see the
The TAOS
Command-Line Interface 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
system and IP configuration for the unit, although you can choose to perform
subsequent configuration tasks remotely through a Telnet session or SNMP, or by
downloading configuration files using TFTP.
