UNIX platforms
Communication Manager running on DEFINITY servers which use an
Oryx/Pecos operating system (proprietary UNIX-based OS) receives a command
from Avaya site administration to adjust the time. Avaya site administration is
synchronized to the LAN PC’s clock.
Trunk group circuits
Trunks provide the communications links between Communication Manager and
other switches, including central office switches and other premises switches.
Trunks that perform the same function are grouped together and administered as
trunk groups. Trunks interface with Communication Manager through port circuit
packs.
