The DS3-ATM trunk module provides a coaxial copper interface between the Stinger
unit and the carrier ATM core network. The DS3-ATM trunk module supports two
44.736Mbps interfaces and connects each interface to an ATM switch.
Two versions of the OC3-ATM trunk module are produced. One version is for use in
the Stinger MRT 23, a second version is for use in the Stinger MRT 19 chassis. These
versions are not interchangeable. For product code information about these modules,
see "Stinger MRT models and optional products" on page 1-2.
After installing a DS3-ATM trunk module and connecting it to an ATM switch, you
verify connections by checking the status lights. You then configure the physical link.
Use a status profile to display the state of the DS3 line and any error conditions.
Note
The TAOS software addresses the single trunk module slot of the Stinger MRT
as slot 18. This is consistent with number of the second trunk module slot in larger
Stinger models.
Installing a DS3-ATM trunk module
A DS3-ATM trunk module is installed in the same manner as any trunk module. (For
details, see "Installing a trunk module" on page 3-12.) After installation, the module
must be connected and configured according to the instructions in this guide.
