Administrative configuration
Each Stinger MRT has an RS-232 serial port (labeled CONSOLE) and a 10BaseT
Ethernet port that can be used to connect to the Stinger MRT to perform
administrative functions. Some Stinger units (model MRT-AD-36S-56K) also have an
internal analog modem that can be used for dial-in administrative connections.
The serial port is for system management from a local workstation. It is also the
standard port for error output, stack traces, and messages in the event of a system
crash. Until you have configured IP addresses on the system's Ethernet interface, you
can use a local terminal or workstation connected to the serial port of the Stinger
MRT to configure the unit.
The system's 10BaseT Ethernet port is intended for light administrative and
management traffic. Once you have assigned an IP address, you can telnet into the
unit from a local host and download configuration files from a TFTP server to the
Stinger system. A Stinger unit has a range of options for configuring IP and for
protecting the unit from unauthorized administrative access.
The internal modem is intended for administrative connections over an analog POTS
line. For modem connection and configuration details, see "Connecting to and
configuring an internal modem" on page 6-12.
Line configuration
Stinger MRT units support ADSL, ASDL over POTS, and SHDSL service, depending
on the model purchased (see Chapter 1, "Introduction to the Stinger MRT"). Each
port on a Stinger MRT has a variety of configuration options, including line rates and
bandwidth. The way you configure each line depends on the model you have
purchased, and your connectivity needs.
For specific information about line configuration, see Chapter 7, "Configuring the
ADSL Line Interfaces," or Chapter 8, "Configuring the SHDSL line interfaces."
Trunk module configuration
A Stinger MRT can be equipped with a trunk module that supports E1, T1,
OC3/STM1, or DS3 service. The trunk module can connect the Stinger to another
ATM switch. The line configuration includes settings that must match between the
local and far-end switch interfaces.
When a trunk module is installed in a Stinger MRT unit, use of the show command
gives the appearance of two trunk modules, as shown in the following example:
