Abstract
A heterogeneous functions-integrated communication device which is improved in the efficiency of optical connector connection/disconnection work and which enables non-redundant arrangement without the need to increase the size of the device. Those DS3 interface connectors of a customer interface section which are required only in the non-redundant arrangement are mounted on an expansion shelf, whereby the size of a shelf body is reduced and, in the case of redundant arrangement, the expansion shelf may be detached. Optical fibers can be introduced at a front side of the device from obliquely below to plug-in units, so that the optical fibers can be connected/disconnected without the need to pull out the plug-in units. Also, fiber trays are arranged at center and bottom levels, respectively, with respect to the height of the shelf body, and an upper part of each fiber tray is made smaller in width than a lower part thereof to thereby define a longitudinal opening, so that the optical fibers extending from the plug-in units can be introduced into the respective fiber trays through the openings.
