Type 2a and Type 2b TeleLite “Campus” Configuration

In  a  “Campus”  Deployment  of  Ethernet,  the  TeleLite  Ethernet  cards  are  used  to  transport  and
distribute  on-site  Ethernet  services  to  other  buildings  or  facilities  were  it  is  desired  to  use  fiber
instead of copper to carry the Ethernet traffic, either because of the distance limitation on copper or
electrical  potential  differences.  A  single multi-port  modem or  several individual modems  can  feed
the TeleLite Ethernet card. The actual location may be fed from a network by copper or fiber. See
Figure 16.
