4 APPLICATIONS
4.1 Testing and Fault Isolation
Terminating all digital operational and test equipment at the DSX-3 (DSX-4H-24) Rear Cross-
Connect greatly reduces the amount of time and skilled personnel required for testing and isolation
of troubles. Identification of existing or developing problems is readily accomplished by:
• Testing at circuit module jacks connected directly to digital equipment inputs and outputs.
• Patching in spare equipment for suspected faulty units.
4.2 Interoffice Service Restoration
The loss of a major facility may isolate or greatly reduce communication capability between
the two locations. To temporarily restore partial communications, circuits can be rerouted
through a third location. The reroute is established with simple patch arrangements at the
cross-connect systems at three sites. After the facility is repaired, the reroute patches are
easily removed and normal service is restored.
4.3 Traffic Pattern Changes
Major changes in traffic patterns may be required on a regular basis (daily, weekly, etc.), or on
a long term basis because of a large corporation relocating within the boundary of the serving
office. Any of these requirements can be met by patching or reconfiguring cross-connect
cables at the cross-connect system.
4.4 System Expansion
The DSX-4H-24 facilitates planning for future growth. The system can be grown from, a
minimal installation of one chassis with up to 24 circuit modules, to any number of full bays.
4.5 Office Layout
The DSX-4H-24 makes it possible to add equipment to an office without major changes in the
office layout. Equipment is simply installed where space is available and then cabled to the
centralized cross-connect system. Cross-connect cables on the cross-connect system connect
the equipment into the desired office electrical configuration.
4.6 Cutover To New Digital Switch
The DSX-4H-24 simplifies the cutover to a new digital switch. When a digital switch is
installed, it is terminated on the cross-connect system. The cross-connections serving the
existing switch are then replaced by temporary patch cords, and new cross-connect jumpers
are installed for the new digital switch. Cutover to the new switch is then completed by
removing the temporary patch cords.
