1.3.6.2 Digital Path
The Digital services from the corporate LAN (received via Ethernet Switch) are converted to optic signals by the CEU
(Centralized Ethernet Unit) and routed over optic fibers towards the GEM units. The optical traffic is then converted to 1GbE by
the GEM (Gigabit Ethernet Modules) modules and distributed to two third party equipment such as Access Points, Ethernet
switch, etc.
Note: GEMs can be connected to the CEU either directly, or via an ICU (described in section 1.3.6.1 ). In that case, the ICU can
also provide DC to the GEMs.
