Detailed Description of the Embodiments
There is a need for wall boxes which allow migration of technologies in the same box. One area where wall boxes may be used is in a setting where the telecommunications medium changes over time, requiring changes in the
telecommunications equipment.

Figure 71 shows the same mounting hole pattern between the prior art wall box and the wall box 806 of Figures 68 and 69. For customers wanting to migrate from the wall box of Figure 70 to the wall box of Figures 68 and 69, the coaxial splitter 20 is removed and mounted to the base 8 as shown to the Figure 69. The same hole pattern for the new wall box is provided to mount the box to the same vertical surface.
Referring now to Figures 72-80, the wall box 806 of Figures 68-69 allows for an initial migration step for adding an RFOG device to the arrangement as in Figure 65. There is a fiber overlength basket 110 which is hinged to the base 8 at hinge 108, and a mounting plate 112 which is hinged to the overlength basket 110 at hinge 114. Both hinges 108, 114 are lower hinges, positioned horizontally when wall box 806 is mounted to the wall. Both hinges 108, 114 are also positioned adjacent to one another. Such arrangement of the hinges allows for convenient technician access to the different levels inside wall box 806. Also, the cables are not pulled when moving between levels, as can be seen in Figures 79 and 80.
An RFOG device 22 is added as shown in Figure 72. The tray 30 in the form of a basket 110 and a mounting plate 112 can be added at Day 2. Basket 110 includes a fiber input area for input from the cabinet in an upper corner, and also an input area in an opposite upper corner from the premises which is to be connected through wall box 806.
Referring now to Figures 75 and 76, the overlength of cable from the cabinet can be mounted in the overlength basket 110. A moveable slider 116 is utilized to help with fiber retention. A cable entry location in the upper corner 118 allows for entry of the 5mm tubing 120. Fiber cable 50 exits the overlength basket and is connected to a front side 112a of the mounting plate 112. A rear side 112b of the mounting plate 112 can house one or more splice locations 122 if splicing is desired. In one example, the cable is a blown fiber which does not require splicing, and is connectorized or preteraiinated on both ends. Splicing can be used to repair the cable if necessary.
When adding the RFOG device 22, the cable basket 110 can be used to avoid recoiling of overlength in that the coiled cable can be mounted directly to the basket without a recoiling operation, if desired. A lower clip 128 can be provided to assist with retention of the coiled fiber. Mounting plate 112 includes an integrated splice tray which has entry points on opposite sides of mounting plate 112, and a Figure-8 dual location for cable reversal.
Referring now to Figures 77 and 78, the RFOG device 22 can be mounted to the mounting plate 112 in a variety of manners, such as with a strap 124, or fasteners 126.
