This chapter describes the basic operation of the Stinger MRT unit as a stand-alone
DSL access multiplexer. Multiple Stinger MRT and MRT-2 units can also connected
together as a hosted system. Hosted operation is described in Appendix B, "Hosted
Operation of Cascaded Stinger MRT units."
Stinger MRT operation as a DSL access multiplexer
Some models of the Stinger MRT contain integrated splitters. These splitters provide
ADSL and analog POTS service over the same pair of wires to the subscriber. Models
of the Stinger MRT that do not contain splitters only provide ADSL or SHDSL data
service.
The separation of the ADSL data and analog voice signal is an electronic function of
the splitters. It does not require configuration. Although parameter settings may vary,
the parameters, commands, and procedures used to configure DSL lines and ATM
connections are the same on all Stinger MRT models.
Operation with integrated splitters
A Stinger MRT with integrated splitters operates as an ATM switch-through digital
subscriber line access multiplexer (DSLAM) that also provides analog voice service
over the same pair of subscriber wires. It switches data from multiple ADSL
subscribers onto a high-speed ATM backbone and splits the voice signal for
connection to a POTS switch. Figure 5-1 shows this type of operation.
