Introduction to the Stinger MRT
Virtual slot conventions for the Stinger MRT
Some Stinger MRT models also incorporate integrated line splitters to provide
asymmetric digital subscriber line (ASDL) and analog telephone (POTS) service over
a single pair of wires. For chassis details, including model number designations, and
line capabilities, see Table 1-2.
Virtual slot conventions for the Stinger MRT
The highly integrated Stinger MRT 19 and Stinger MRT 23 use the same TAOS
software as larger Stinger units. In the larger Stinger units TAOS uses the physical slot
number in which modules are installed to access the parameters of those modules
and configure them. In the Stinger MRT, functions are grouped into virtual slots, so
that they can be accessed and configured by the TAOS software in a manner similar
to other Stinger models.
Table 1-1 compares the physical slot locations of modules installed in a Stinger FS
with the virtual slot locations for the same functions integrated into the Stinger MRT.
These virtual slot positions are used in examples throughout this document.

Stinger MRT models and optional products
Two models of the Stinger MRT 23 are available to support different ADSL line
lengths. The original Stinger MRT 23 was designed for field installations with short
ADSL subscriber loops. This model supports speeds up to 8.128Kbps over 24
American wire gauge (AWG, 0.25 mm²) copper facilities up to 2000 feet, and lower
speeds beyond that distance.
A newer standard-reach version of the MRT 23 supports the standard ADSL
subscriber loop length, identical to the full-sized central office version of the Stinger.
This standard-reach version supports speeds up to 8.128Kbps over 24 AWG (0.25
mm²) copper facilities up to 8000 feet in length, and lower speeds beyond that
distance.
Two models of the MRT 19 are also available. One model of the MRT 19 supports up
to 48 ADSL connections without POTS capability, and another supports up to 36
SHDSL connections.
The two versions of the Stinger MRT 23 can be ordered with different trunk modules
or software options installed for different bandwidth requirements. Trunk modules
for the Stinger MRT 19 models are ordered separately, the base chassis are supplied
with a blank faceplate covering the trunk module slot. Optional software is available
