We have had a few posts about the Network Operations Centre ("NOC") so we thought we would give you a little more information about what the NOC does.  NOCs are a vital part of network infrastructure.  The essential task of the NOC involves surveillance of the health of the network 24/7/365.  The NOC also performs other vital functions.  These include: supporting the operating and engineering teams in maintaining the network; ensuring timely communication of planned maintenance works; coordinating activities associated with issue rectification; and generally processing requests from customers.
