A System Solution

RZX-3 is designed as a total system solution – not just components Focused on simplifying the solution, the system approach provides ease of expansion, streamlines cross-connect jumper installation and reduces premature jumper exhaustion And with one part-number ordering, your engineering, purchasing and installation labor is greatly reduced

Standard system features include what’s most important to your success RZX-3 is the ultimate in density The 4” chassis contains up to 32 circuit frames in a 19” width offering greater density than any other mid- size jack interface in the industry RZX-3 continues ADC’s tradition as the industry leader in cable management Designing the RZX-3 system with a rear adjustable cable tray, you’re prepared to accommodate maximum cable density Permanent equipment connections have been recessed to allow the quick identifiable access to semi-permanent cross-connect BNCs And, with its “plug and play” architecture, the RZX-3 system

is fully modular throughout chassis, circuit frames and jacks Individual BNC circuit frames remove easily from the chassis providing the most simplified and cost-effective restoral capabilities available

Built for Reliability

Our robust DSX jack design is constructed with mechanical support to ensure lifetime service, not by a der type connection on a printed circuit board ADC’s highly durable BNC is standard in the RZX-3 system Its solid cylinder design has a closed entry contact to prevent spring contact overstress We don’t use Teflon insulators, ensuring true 75 ohm impedance RZX-3’s sealed jack has firewall protection preventing environmental contaminants from disturbing switch contacts Add to all this ADC’s proven “make-before- break” switching design Make-before-break contacts ensure that high speed signals never go open or un- terminated during in-service patching DS3 signals are always terminated to a 75 ohm load preventing signal oscillation that can lead to bit errors during patching

Maximum cable limits (based on 735 type coaxial cable) and cable connection diagram are illustrated above The RZX-3 system is designed for miniature 735 type coaxial cable The use of larger diameter coaxial cable will add to cable congestion and may limit the growth of the DSX system.

To keep pace with technology and customer demands that seem to change daily, your network must be

100 percent reliable and completely flexible A vital part of today’s network migration strategy, the DSX enables patching, terminating and rearranging of circuits as traffic patterns change and demands on the network grow.

The RZX-3 Rear Cross-Connect System is designed for configurations capable of 24 or 32 modules in a single 4" high x 19" wide chassis These incremental chassis counts match up perfectly to North American SONET group counts of 3 and 12, digital cross-connect (DCS) group counts of 12 and 16, and international SDH group counts of 16 RZX-3 supports all Coaxial Interface Digital Signal Rates; including DS3, DS-4NA, DS4, STS-1, STS-3, E1, E3, STM-1

RXZ-3 is suitable for all locations where high density space savings are required, such as:

• Central office hub nodes

• Intermediate distribution nodes

• Point of presence (POP) carrier handoff nodes

• Customer premise nodes

• Huts, CEVs, Cabinets

This high density Digital System Cross-Connect (DSX) provides cable termination, jack access and nect functions in a coaxial based broadband network to form a centralized cross-connect (distribution frame) for digital signals Designed to be transparent in the digital hierarchy, DSX equipment permits temporary jack access, cross-connection, reconfiguration and restoration of various digital circuits Internal jack circuits provide input/output connections to each digital signal level source

cross-con-Each Network Element (NE) is permanently cabled to a separate DSX-3 module Any NE may be connected

to any other NE in a non-dedicated manner by means of a semi-permanent cross-connect jumper placed between two DSX-3 modules The cross-connect jumper allows flexibility for network reconfiguration in the future LEDs at each DSX module identify both NEs that are cross-connected together Digital signals are accessed through the IN, OUT and MONITOR jacks at each DSX module for testing and patching operations.

Pre-Termination Option

The RZX-3 chassis may be initially configured with circuit frame modules, but no jacks, in order to create a fullymodular pre-termination connection point for equipment cables Similar to the deployment of network elementsthat are not equipped with electronic circuit cards until service is required, the RZX-3 can defer the cost of jacksuntil service is required The chassis and cable infrastructure may be constructed in preparation of future servicedemand, while jack costs are deferred until revenue generating service is turned up Unlike any other pre-termi-nation DSX chassis, this fully modular design allows any single component to be replaced if damaged, withoutinterrupting adjacent in-service circuits

The rear cross-connect modules have jacks for temporary access on the front of the module, permanent equipment cable interface connections on the rear of the module, and semi-permanent cross-connect interface connections on the rear of the module.

The DSX-4R pre-terminated chassis option allows

network elements to be cabled to the DSX without

deploying the DSX jacks This feature allows the

cost of jacks to be deferred until revenue is

gener-ated by service demand.

Each position of the pre-termination chassis is

equipped with a circuit frame including BNC

recep-tacles Network elements are cabled during initial

installation When service turn-up is required, a

jack kit is plugged into the circuit frame to

com-plete the circuit and provide jack access for testing

A typical DSX system consists of DSX modules and chassis placed in bays (racks) Network elements are cabled to the DSX modules and are then connected to each other by means of a semi-permanent cross-connect jumper placed between two DSX modules The management of equipment cables and cross-connect jumpers must be addressed at the DSX framework to ensure a non-blocking network with growth potential DSX-4R is designed for use with miniature type coaxial cable (i.e 735) The use of larger diameter coaxial cable will severely congest and may limit the growth of the DSX-4R system.

The typical cross-connect system lineup shown in Figure 1 illustrates the hardware layout design for current (3 bays) as well as future growth requirements Spacing between bays allows for routing of equipment cables into each bay The spacing also provides room for jumper rings placed on the bay for control of vertical jumper routing within the same system Notice that a spacer is provided at the growth end of the lineup and is ready for the next bay addition The spacer width between bays is determined by the number of DSX terminations per bay and the type of coaxial cable used The use of miniature type coaxial cable significantly reduces the spacing requirement.

In multiple lineups, the top chassis position in each bay should be reserved for a cross aisle panel to extend cross-connects to other lineups.

Typically, every third or fourth bay within a DSX lineup is designated as a maintenance bay Maintenance equipment such as writing shelves, miscellaneous storage, communications panels, interbay patch panels, bridging office repeaters and test sets is placed in this bay, providing quick and convenient access to all terminations These maintenance bays allow office technicians to maintain digital services efficiently Any remaining space within the maintenance bay may be used for DSX-3 chassis.

net-Miscellaneous and maintenance type equipment such as bridging office repeaters, cross aisle panel, interbay patch panel, equipment shelf for portable test set, communications panel, pen- cil and storage drawers, etc., may be substituted for a chassis.

In multiple lineup systems, the top chassis position in each bay should be reserved for a cross aisle panel for extending cross- connects to other lineups.

Traditionally, as DSX frameworks grew, DSX chassis and the jumper rings associated with them were added one by one Existing cross-connect jumpers had to be fed into the new jumper rings as the new chassis were installed Jumper movement in any one direction was often restricted since jumper rings were not present at unequipped chassis positions If jumpers were pulled too tightly across unequipped positions, feeding them into new rings was difficult if not impossible Also, jumpers may have cut across corners as they transitioned from vertical to horizontal wireways.

To solve these problems and greatly ease the process of growing a DSX lineup, ADC offers skeleton bays, preassembled bays with all cable and jumper management, but no chassis or modules Bay spacers, end guards and other miscellaneous hardware are ordered as required Pre-provisioning all cable management ensures that existing jumpers need never be touched when chassis are added to the bay Jumper routing is never restricted since all wireways are pre-provisioned.

Skeleton bay framework may be provisioned to expand an office easily by providing enough empty bays for

a given engineering period or an entire lineup may be installed for fast growing offices Growing the DSX requires adding a DSX chassis as usual and installation time is reduced since working with existing jumpers

is not a concern.
