Figure 2. DSXpert 2005 Modular Chassis with Modules Inserted (modules may vary), Rear View
1.2 Description
The DSXpert 2005 DS3/E3 Remote Test Access System chassis and modules, hereafter
referred collectively as DSXpert, provide a common point for remote test access to DS3
(44.736 Mbps) and E3 (34.368 Mbps) digital bit rate circuits. The chassis backplane serves as
an interconnection point for DS3/E3 circuits connected between facility and equipment sides
of a network. Modules provide chassis power, test access functionality and support for
DS3/E3 circuits, test equipment and remote connections.
Modules for the modular chassis include several DS3/E3 line access card sets, a test card set,
control card and power supplies. The control card is a microprocessor-based card that contains
the system firmware and provides control for the entire chassis. It coordinates all unit
functions and communicates with other units, control consoles and other management devices.
The Test Card set coordinates functions for test devices connected to the chassis. The Test
Card set consists of one front card and one corresponding rear card, and provides BNC ports to
support two test devices. The Line Access Card sets coordinate functions for the DS3/E3 lines.
Each Line Access Card set consists of one front card and two corresponding rear cards, and
provides BNC ports to support two DS3/E3 circuits. The Power Supplies provide power at -48
V DC to the chassis and modules. Only one Power Supply is required for operation. A second
Power supply provides power supply redundancy.
The DSXpert equipment is normally shipped with the modules installed in the chassis. If the
modules are not contained in the chassis location slots when the equipment is received,
perform the necessary module installation procedures.
