Problems solved by technology

The downside of this total replacement of the rack and cabling is the higher cost of updating the system
Another disadvantage is that connected users need to experience longer downtime, because the replacement of the entire system requires longer installation time than just replacing the printed board and subrack

Embodiment Construction

[0019] The present invention relates to equipment for use in telecommunication systems and is described with reference to the accompanying drawings 1-3. The apparatus comprises a rack 100 for housing electronic printed boards 210 . The printed board 210 is installed in the rack 100 through a plurality of subracks 110 , 200 , 320 , wherein the plurality of subracks 110 , 200 , 320 are adapted to be installed in the rack 100 .

[0020] The present invention relates to a subrack 110, 200, 320 adapted to be mounted in a rack 100 as shown in FIG. The internal dimensions of the frame 100 are such that it is suitable for mounting a first type of printing plate 140 having a first set of dimensions. The subrack 110, 200, 320 of the present invention is adapted to mount at least one printed board 130 of a second type, wherein at least one dimension of the or each printed board of the second type is greater than at least one dimension of the first set of dimensions.

Abstract

The present invention relates to a subrack for housing printed boards in a telecommunication system wherein the subrack is adapted to be mounted in a rack, and the inner dimensions of the rack is such that it is adapted to mount printed boards of a first type via a plurality of conventional subracks. The subrack is adapted to mount at least one printed board of a second type essentially perpendicular, when mounted in the rack, compared to the printed boards of the first type mounted in the plurality of conventional subracks when mounted in the rack, wherein the size of at least one dimension of the or each printed board of the second type is greater than the size of at least one of the dimensions of the printed boards of the first type. Moreover, the invention relates to a cable adapter for connecting a connector of the rack comprising the subrack according to the invention to a printed board of the second type mounted in the subrack.

Description

technical field [0001] The present invention relates to equipment for use in telecommunications systems, and more particularly to subracks and cable adapters. Background technique [0002] A rack, also known as a cabinet, is an enclosure used to house electronic equipment for a telecommunications system. Inside a rack, a number of subracks are usually installed, each of which is a metal frame or box equipped with electronic printed boards implementing the functionality of the telecommunication system. A backplane can also be included in the subrack for power distribution. Racks are used to protect electronic equipment from, for example, electromagnetic compatibility (EMC), dust, and unauthorized handling. The printed board comprises an insulating board material with a pre-etched copper layer in which the electronic components are secured by soldering. The cabling required for the rack is the line connections for the subscribers, the power cabling for each subrack, and the...
