Preparing for Shelf Installation in a Central Office (CO),
Multi-Tenant Unit (MTU), or Remote Terminal (RT)
NOTE
References to common, but differing, parameters between the Total Access
3000 and the Total Access 3010, such as number of slots, will be conveyed
by the convention a/b. The “a” represents the Total Access 3000 parameter
and the “b” represents the Total Access 3010 parameter. For example, the
differing number of access slots in the two platforms, 28 for the Total Access
3000 and 22 for the Total Access 3010, would be displayed “28/22.”
1.1.1
Introduction
This document provides details of how a CO, MTU, or RT should be prepared to
accept the installation of one or more Total Access 3000/3010 shelves. Shelves that
will be installed in the same bay or in adjacent bays should be engineered together so
that they can share common feeds for power, timing and management interfaces as
appropriate for the application.
1.1.2
Prerequisite Procedures
Before beginning the site preparations described below, the Site Engineer should
review the Engineering Guidelines and Application Guides to determine which system
applications each shelf will be wired to perform. Based upon application, the Site
Engineer should specify how the bay holding the shelves should fit into the NEBS
lineup for CO applications. The same type of considerations should be made for RT
and MTU applications. These considerations include which power, transmission, and
clock connections will be required for each shelf.

Space Considerations
1.2.1
Fitting the Shelf into NEBS Lineups
The Total Access 3000/3010 shelf is designed to flush-mount or mid-mount in any
standard 23-inch/19-inch network bay or unequal flange relay rack. Since the shelf
meets the 12-inch NEBS depth profile, it may be mounted in any 12-inch, 18-inch or
24-inch network lineup. Full cable routing support is provided for power and
transmission cables in both flush-mount and mid-mount configurations.
1.2.1.1 Vertical Space Requirements
Each shelf occupies 6 inches of vertical space in the rack. The heat baffle/
fiber routing tray occupies an additional 4 inches of vertical rack space. In a
typical application, several shelves may be stacked with a heat baffle
separating them. This arrangement results in each shelf and associated baffle
occupying 10 inches of vertical space. An additional heat baffle is
recommended to act as the cool-air intake on the bottom shelf in a stack.
