large extension node

Definition/Scope: (FM 11-55) The large extension node (LEN) provides wired communications for personnel at large command posts (CPs). A LEN enables up to 164 wired subscribers to communicate freely through the large extension node switch (LENS) using automatic flood search routing. Subscribers have access to the NCs and to the rest of MSE via LOS radios that connect to the LENS by cable or super high frequency (SHF) radio systems. The LENS also provides automatic subscriber finding features that allow permanent subscriber address assignment and removes the requirement of knowing where the subscriber is physically located.
