OVERVIEW: SYSTEM 85 AND DEFINITY GENERIC 2 WITH TRADITIONAL MODULES AT&T System 85 and DEFINITY® Generic 2 Communications System (hereafter abbreviated to DEFINITY Generic 2 or Generic 2) with traditional modules are communications systems with multimodule architecture that provide integrated voice and data switching via a state-of-the-art communications processor (called the common control or CC), a time-multiplexed switch (TMS), and the communications modules.
  • Page 18 OVERVIEW: SYSTEM 85 AND DEFINlTY GENERIC 2 WITH TRADITIONAL MODULES The MC, or communications switching module, is the basic building block of the multimodular architecture. Each MC is capable of supporting up to 1536 analog ports and 256 simultaneous full- duplex conversations.

(See figure 2-1, Maximum Column 1500 Pairs (Five 300-Pair Terminal BIocks).) Higher columns are hard to reach and make connecting and disconnecting jumper wires difficult.

    MDF/lDF DESIGN: SYSTEM 85 AND DEFINITY GENERIC 2 WITH TRADITIONAL MODULES Connecting Jumper Wires To facilitate cross-connections, connect jumper wires as follows: Use the layout and instructions shown in figure 2-2, Jumper Placement, for the 110A terminal blocks. (Figure 2-2 illustrates a layout for frame mounting, but the layout applies to wall mounting as well.) Use only the number of jumpers required for a connection.

Frames ordered for 110A hardware come with 110AB1-300 terminal blocks, clear designation strips, and wireways installed. However, you must specify the 110C-4 connecting block, which is recommended for a System 85 or DEFINITY Generic 2 traditional system installation.

  • Page 32: Designing The Mdf For A Raised Floor

    MDF/lDF DESIGN: SYSTEM 85 AND DEFINITY GENERIC 2 WITH TRADITIONAL MODULES DESIGNING THE MDF Designing the MDF is a two-step process: first, determine the size of the MDF, second, construct the MDF. As you proceed with the design, keep in mind that function is more important than cost in reaching a final decision since it is possible for the final installation to be inexpensive but nonfunctional.

  • Page 34 MDF/lDF DESIGN: SYSTEM 85 AND DEFINITY GENERIC 2 WITH TRADITIONAL MODULES Two factors govern the size of the MDF: the number of cable pairs to be terminated and the type of cross-connect hardware used. Since the recommended cross-connect hardware for System 85 and DEFINITY Generic 2 traditional system is the 110A, you only need to calculate the number of cable pairs that must terminate on the MDF and calculate the number of 110A cross-connect blocks needed to terminate those pairs to arrive at the size of the MDF.
  • Page 35 2-12 MDF/lDF DESIGN: SYSTEM 85 AND DEFINITY GENERIC 2 WITH TRADITIONAL MODULES beyond these minimums as actual needs dictate. Equipment (Switch) Port Field The equipment port field, which uses purple labels, is where the cables from the equipment ports terminate. Two factors govern its size. The first is the type, usage, and number of port carriers; the second is module needs, since all ports from an equipment module must be colocated.
  • Page 36 MDF/lDF DESIGN: SYSTEM 85 AND DEFINITY GENERIC 2 WITH TRADITIONAL MODULES NOTE: When a blue field is used, the blue field cross-connects directly to the purple field and not to the white field. Terminate only six 4-pair DIW cables to each index strip of a 110AB1-300 wiring block (the 25th pair is unused), which means that you can terminate a maximum of 72 four-pair DIW cables on each 300- pair wiring block.

  • Page 45 2-22 MDF/lDF DESIGN: SYSTEM 85 AND DEFINITY GENERIC 2 WITH TRADITIONAL MODULES In addition to the preceding guidelines, observe these rules when designing zones: Mount the hardware on frames. For one-zone installations, wall-mounted frames may be used. For two-zone installations, double-sided, self-supporting frames must be used. Divide the distribution cables (in 100-pair increments) as equally between zones as possible.
  • Page 46 MDF/lDF DESIGN: SYSTEM 85 AND DEFINITY GENERIC 2 WITH TRADITIONAL MODULES NOTE: If station #2700 is located in module 04, the cross-connection in the closet goes to a pair in zone 1. Similarly, if #3001 is in module 07, the cross-connection in the closet goes to a pair in zone 2. Using this rule, it is possible to keep the jumpers short at the equipment room cross-connect field.

    ELECTRICAL PROTECTION: SYSTEM 85 AND DEFINITY GENERlC 2 WITH TRADITIONAL MODULES For more details on electrical protection, see Telecommunication Electrical Protection (350-060). Riser Cable Although riser cable (the distribution cable that stays within a building) rarely receives direct lightning strikes, instances of risers subjected to residual voltages as high as 5000V from lightning strikes on the buildings housing them have been observed.

    ELECTRICAL PROTECTION: SYSTEM 85 AND DEFINITY GENERIC 2 WITH TRADITIONAL MODULES primary protector operates at a lower threshold. A secondary protector protects against currents and, in some cases, residual voltages that get past the primary protector. When analog circuit packs, analog voice terminals, and the distribution cables and cross-connect fields serving them are exposed to lightning, power crosses, and/or ground-potential rise, they require only overvoltage protection because they already have built-in, sneak-current protection in the circuit packs and terminals.

  • Page 61: Primary Protection

    ELECTRICAL PROTECTION: SYSTEM 85 AND DEFINITY GENERIC 2 WITH TRADITIONAL MODULES PRIMARY PROTECTION Primary protection is provided by a fusible link and an overvoltage device. The following are descriptions of these elements of primary protectors. Overvoltage Devices There are three types of overvoltage devices: carbon blocks, gas tubes, and solid-state devices. Carbon Blocks A carbon block is a device holding two or more small carbon electrodes gapped at a distance that allows a voltage power surge to arc across the gap to ground.

    ELECTRICAL PROTECTION: SYSTEM 85 AND DEFINITY GENERIC 2 WITH TRADITIONAL MODULES Sneak-Current Device: Fuse A sneak-current fuse is a fuse that melts when currents of .35A (for 4 hours) to 5.25A (for more than 10 seconds) reach it. Sneak-current fuses may be installed before or after the network interface (NI) in series with the primary protector.

    Remote Modules The UMC carrier can hold up to seven remote module interface (RMI) circuit packs (TN456). Remote modules are supported by System 85 and universal and traditional modules in the DEFINITY Generic 2 system. Call control uses fiber-optic links with a central-to-remote range of up to 25,000 ft. Remote modules with optically-remoted peripheral interfaces (ORPI) for attendant consoles have a maximum range of 13,000 ft.

    OVERVIEW: DEFINITY GENERIC 2 WITH UNIVERSAL MODULES CROSS-CONNECT FIELDS The DEFINITY Generic 2 with universal modules uses System 75 port board technology and has 500 pairs per carrier and 3 carriers per module. This creates significant differences in wall-field design from that used in System 85 and DEFINITY Generic 2 with traditional modules.
