12 Installing and Connecting the MDF and Telephones

Chapter 2: Installing the main distribution frame

If the equipment room does not have one, you must build a main distribution frame (MDF) that connects the media gateways to the building phone network and to the public switched telephone network (PSTN). The tasks include the following:

● Physical requirements and layout on page 13

● Main distribution frame hardware installation on page 17

If the installation will use a patch panel rather than a main distribution frame, use the procedures in Chapter 3: Installing the patch panel

Physical requirements and layout

Before installing the MDF and other equipment in the equipment room, ensure that there is adequate space and there is a plan for placing the equipment.

on page 29.

Installation space requirements

Make sure there is adequate space for the following pieces of equipment:

● Sneak fuse panels and emergency transfer units on page 13

● 110-type hardware on page 13

● Cable Slack Manager on page 14

Sneak fuse panels and emergency transfer units

You need about 8 inches (20 centimeters) of horizontal wall space for each column of sneak fuse panels. Horizontal wall space must also be provided for emergency transfer units.

110-type hardware

The trunk/auxiliary field and the distribution field are mounted on the same wall. Each 110P-type terminal block is 8.5 inches (21.6 centimeters) wide. Vertical patch cord troughs are 5.31 inches (13.4 centimeters) wide and horizontal patch cord troughs are 23 inches (58.4 centimeters) wide.

Each 110A-type terminal block is 10.8 inches (27.4 centimeters) wide; however, no horizontal patch cord troughs are used and the blocks are shorter than 110P-type terminal blocks. This allows the 110A-type terminal blocks to be stacked. Therefore, the 110A-type hardware requires less space than the 110P-type hardware on a per-station basis.

Installing the main distribution frame

Cable Slack Manager

A Cable Slack Manager is 32 inches (81.3 centimeters) wide. Slack managers are commonly used in installations consisting of media gateway stacks, such as the SCC1 Media Gateways. Determine the quantity of slack managers by dividing the total length of the MDF in inches (centimeters) by 32 (81.3). A partial number of 0.4 or less should be rounded down, and a partial number of 0.5 or more should be rounded up (for example: 2.4 = two Cable Slack Managers and 2.5 = three Cable Slack Managers).

Note:

Note: Cable clamps are required in installations with Cable Slack Managers. At the rear

of the media gateways, on each rear ground plate, install two cable clamps using the screws provided. These clamps hold the 25-pair input/output or MDF cables in place.

Installation layout

Make sure you review the following information:

● Information outlet locations on page 14

Information outlet locations

The customer or marketing representative must provide floor plans showing the information outlet locations and types (flush- or surface-mounted) required. The floor plans must also show a complete overview of all conduit and cabling facilities in the building.

Site, satellite, and adapter locations

Use the following information when determining site, satellite, or adapter locations.

● Keep the number of locations to a minimum.

● To minimize the station wiring distances, centrally locate the sites/satellites, or adapters

among the information outlets.

● Site/satellite locations must be easily accessible and contain AC-powered receptacles.

One 258A/BR2580A adapter is required for each 25-pair station cable containing 4-pair station circuits. One 356A adapter is required for each 25-pair station cable containing 3-pair station circuits. Hardware requirements are the same as for the equipment room.

14 Installing and Connecting the MDF and Telephones

Physical requirements and layout

Sizing 4-pair station cables

Use the scale of the floor plan to determine the approximate length of the station cables required per the standard SYSTIMAX wiring concepts.

Sizing 25-pair and multiple 25-pair station cables

Use the scale of the floor plan to determine the approximate length of each 25-pair station cable. The cables must be selected and properly sized to make maximum use of the hardware at the equipment room or satellite location.

Use 25-pair B25A cables to connect adapters directly to the MDF or satellite location. Staggered-finger cables, equipped with factory-installed 25-pair connectors at both ends, should be used when multiple 25-pair cables are used between the equipment room or satellite location and the adapters. B25A cables are required at the equipment room or satellite location to connect the staggered-finger cables to the 110-type terminal blocks.

Use the following information to determine the cable size (cable pairs) required for either 3-pair or 4-pair circuits. Note the length and size on the floor plan to aid in the ordering and installation of the station cables.

3-pair station cable circuits

To determine the size of station cables containing 3-pair circuits, multiply the number of 3-pair circuits required at the satellite location by 3.5. Then, using the minimum size cable requirement, round up the cable size requirement to the next highest available cable bundle size. This will provide additional pairs for growth and compensate for every twenty-fifth pair in a cable that is not used.

4-pair station cable circuits

To determine the size of station cables containing 4-pair circuits, find out how many information outlets are served by the equipment room MDF or satellite location MDF. Multiply the number of information outlets by 4. Then, using the minimum size cable requirement, round up the cable size requirement to the next highest available cable bundle size.

Note:

Note: This formula may not compensate for the unused 25th pair in all cases. If not, it

must be allowed for.

Installing the main distribution frame

Main distribution frame cross-connect fields

Each main distribution frame (MDF) contains a trunk/auxiliary field and a distribution field. The trunk/auxiliary field contains three cross-connect areas:

● The green field terminates the network interface leads from the central office (CO) and

provides the terminals to cross-connect the leads to the purple or yellow fields as required. A single row of the 110-type terminal block can terminate 24 1-pair, 8 3-pair, or 12 2-pair trunks.

● The purple field terminates the trunk circuits from the media gateway with WP-90929, List

1 or 3 concentrator cables. Also, 25-pair cables can be used to terminate trunk circuits from the media gateway with each trunk circuit pack connecting to one 25-pair row of the 110-type terminal block. Each terminal block row can terminate 24 1-pair, 8 3-pair, or 12 2-pair trunks.

● The yellow field provides cross-connect terminals for all miscellaneous leads from the

media gateway, such as alarm monitors, emergency transfer relay power, and attendant console power. This field is used for emergency transfer wiring, paging equipment, music sources, and so forth.

The distribution field contains four cross-connect areas:

● The purple field (port field) terminates 25-pair cables from the media gateway. Each line

circuit pack connects to one 25-pair row of the 110-type terminal block. One 25-pair cable is required for each line circuit pack.

Note:

Note: The TN2183 16-port Analog Line circuit pack requires an adapter cable to

connect from one connector on the media gateway to two 25-pair connectors on a terminal block. The yellow field (auxiliary field) terminates all 25-pair cables from the auxiliary cabinet (if used). The yellow field is located in the lower right-hand corner of the distribution field.

● The white field (station field) terminates the station wiring. The white field indicates 3-pair

station circuits (eight circuits per 25-pair cable) routed through a satellite closet.

● The blue field (station field) also terminates station wiring. The blue field indicates 3- and/

or 4-pair station circuits (eight or six circuits, respectively, per 25-pair cable). The fourth pair, of the 4-pair station circuit provides adjunct power from the cross-connect field on an as-needed basis to telephones and consoles within 250 feet (76 meters) of the MDF.

16 Installing and Connecting the MDF and Telephones

Main distribution frame hardware installation

This section provides information on installing a main distribution frame (MDF) in an equipment room. It must be installed before connecting media gateways to it and before connecting it to the public switched telephone network (PSTN) outside the building and stations within the building.

SYSTIMAX 110-type hardware is used for the MDF. 110-type hardware is available in two basic types: the 110A and 110P. The 110A requires less wall space than the 110P. The 110P includes horizontal and vertical cable troughs for managing cross-connect cables. The media gateways are connected to the MDF with the supplied B25A male to female 25-pair cables. The cables are provided in 10-foot (3 meter) and 15-foot (4.5 meter) lengths.

Figure 1: Example MDF connections (MCC1 Media Gateway)

shows the cross-connections for

common circuit packs. See this figure when cross-connecting wire pairs to the MDF.

Chapter 3: Installing the patch panel

Installing patch panels

This chapter is for installations using a patch panel rather than a main distribution frame for connections to the building phone network and the public switched telephone network (PSTN). Patch panels are arrays of RJ45 jacks and associated B25A cables. The panels accommodate 2-wire, 24-port DCP/analog port boards and 8-port analog trunk boards. The panels are mounted either below or above the media gateway stack. You cannot mount patch panels in between media gateways.

Note:

Note: You do not have to mount the patch panels in the same rack as the media

gateways. You can mount the panels in telephone closets as appropriate.

For more information, see Figure 10: Typical RMC patch panel installation

on page 30 while

you perform this procedure.

To install patch panels:

1. Use the supplied mounting screws to mount the patch panels on the rack below media gateway A or above the topmost media gateway.

2. Attach B25A cables to the patch panels and the circuit pack amphenol connectors.

Note:

Note: Connect 24-port DCP or analog circuit packs to the 24-port patch panels.

Note:

Note: Connect 8-port analog trunk, “combo,” or DID trunk circuit packs to either of the

first two banks on the 8-port patch panel. If an TN2185B ISDN-BRI S/T-TE Interface (4-wire, 8 ports) circuit pack is present, connect that circuit pack to the third bank on the 8-port patch panel.

Cross-connecting the media gateway to the patch panels

Cross-connect the port circuit packs to the G650 Media Gateway patch panels or other standard 110A cross-connect equipment (Figure 11: Sample cross-connect field patch panel

connections on page 31).
