Page 35
11.1 The Parties will work cooperatively to install and maintain a reliable network. TC
SYTEMS and BellSouth will exchange appropriate information (e.g., maintenance
contact numbers, escalation procedures, network information, information required
to comply with law enforcement and other security agencies of the Government) to
achieve this desired reliability. In addition, the Parties will work cooperatively to
apply sound network management principles to alleviate or to prevent congestion.
11.2 Each Party recognizes a responsibility to follow the standards that may be agreed to
between the Parties and to employ characteristics and methods of operation that will
not interfere with or impair the service or any facilities of the other or any third
parties connected with or involved directly in the network of the other.
12 Outage Notification and Repair Standard
12.1 Planned Outages. BellSouth will use best efforts to notify TC SYTEMS of any
significant planned BellSouth network outage in substantially the same time and
manner as it provides notice to itself or to its End User Customers, its Affiliates, or
any other party. Upon such notice, TC SYTEMS may submit a reasonable request
for additional information relevant to the scheduled BellSouth network outage and
BellSouth may provide such information to the extent the scheduled maintenance
activity may impact TC SYTEMS and such information is reasonably necessary for
TC SYTEMS to identify and analyze potential risks associated with such an outage.
BellSouth may expedite or delay scheduled BellSouth network outages as a result of
unscheduled maintenance or other unforeseen events. In those instances where
BellSouth will not perform a scheduled network outage at the announced times,
BellSouth will make best efforts to provide TC SYTEMS with as much notice as is
reasonably possible concerning the changed schedule.
12.2 Unplanned Outage. For purposes of this section, a significant unplanned BellSouth
network outage is defined as set forth below, which is consistent with 47 CFR
63.100, which includes but is not limited to:
12.2.1.1 An outage which potentially affects a 911 special facility is defined as a significant
service degradation, switch or transport, where rerouting to the same or an
alternative answering location was not implemented, and involves one or more of the
following situations:
12.2.1.2 Isolation of one or more Public Service Answering Points (PSAPs) for 24 hours or
more, if the isolated PSAPs collectively serve less than 30,000 or more access lines,
based on the carrier's database of lines served by each PSAP; or
12.2.1.3 Loss of call processing capabilities in the E911 tandem(s), for 30 minutes or more,
regardless of the number of customers affected; or
