TSP Restoration Information for Vendors
The purpose of restoration priority assignments
is to guide a service vendor on the sequence for restoring NS/EP services
in the event of an outage or failure of multiple services. Vendors must restore all TSP services,
regardless of their restoration priority levels, before
any non-TSP services. This section delineates service vendors' restoration
responsibilities; highlights the method by which service vendors will
receive restoration priority assignments; and presents guidelines for
service vendors to follow to provide priority restoration of TSP services.
Service Vendors' TSP Service Restoration Responsibilities
After receiving a TSP Authorization Code for its service, the service user or its contracting activity will
transmit the code to the prime service vendor on a service
order. The TSP Program Office does not give the TSP Authorization Code directly to the
prime service vendor. This transfer is part of the normal contractual
process that takes place between the service user or its contracting activity
and the prime service vendor. Prime service vendors may not accept
initial TSP assignments, or subsequent orders involving TSP services,
without the TSP Authorization Code.
Service vendors must restore TSP services with restoration priority assignments
before telecommunications services without restoration priority assignments.
However, control services and orderwires that a service wholly owns and operates
and are crucial to the operation of that service vendor's
network are exempt from this requirement.
A service vendor who
accepts TSP service orders must provide 24-hour points of contact (POC) to receive
reports of TSP service outages from service users. This need not be a
single dedicated POC for TSP service outages and may, in fact, be the
contact who would receive reports of normal service outages. When service
vendors recognize that a TSP service is out of service, unusable, or they
receive a trouble report, they will allocate available resources to restore
the service as quickly as practicable. Service vendors will dispatch personnel
outside normal business hours if necessary to restore TSP services assigned
a restoration priority of 1, 2, or 3. Service vendors must
dispatch personnel outside normal business hours to restore TSP services
assigned 4 or 5 only when the next business day is more than 24 hours
Between Service Vendors
Prime service vendors who subcontract
portions of TSP services must convey the TSP assignment to
subcontractors and interconnecting carriers. Subcontractors will accept
and honor the TSP assignment supplied by the prime service vendor. (Service
vendors should refer to internal procedures and industry guidelines regarding
transfer of TSP service information between prime service vendors and
their subcontractors and interconnecting carriers.) Service vendors will
cooperate with other service vendors involved in restoring a TSP service
by honoring requests for restoration assistance. Additionally, all service
vendors, specifically including resale carriers, will ensure that they give service
vendors supplying the underlying facilities the information
necessary to implement priority treatment of facilities that support TSP
If there is a discrepancy
between the records of the prime service vendor and the subcontractor,
the subcontractor will accept the restoration priority supplied by the
prime service vendor while restoring the service. The prime service vendor
is responsible for verifying the restoration priority assigned by the
TSP Program Office and ensuring that both the
prime service vendor and its subcontractor(s) correctly record the information.
Vendors will restore TSP services in order
of restoration priority level: that is, TSP services assigned a restoration
priority of 1 will be restored first; then TSP services assigned a restoration
priority of 2 will be restored, etc.
Service vendors will
restore TSP services assigned the same restoration priority based on the
service vendor's determination of which service can be restored first.
In lieu of a clear distinction, the service vendor will use its best judgment
to determine the restoration order. The service vendor should not normally
interrupt TSP service restoration work in progress to restore another
TSP service assigned the same priority level. The service vendor may allocate its resources in a manner that, in its best
judgment, will most efficiently facilitate restoration of TSP services
as soon as possible.
If the service vendor and service user
or their contracting activity cannot resolve to their mutual satisfaction
conflict regarding the restoration priority of TSP services should
refer the case to the TSP Program Office. However, the service vendor
and service user or their contracting activity should first attempt
to resolve conflicts among themselves. The service vendor should
also refer to its internal escalation procedures and industry guidelines.
In addition, service
vendors may provide priority restoration to multiple service
facilities (e.g., DS1 or DS3 facilities) that contain TSP services, even
though services assigned no priority or lower priority may be restored
along with or sometimes ahead of some higher priority-level services.
Alternatively, the service vendor may reroute individual TSP services
from a failed facility onto another facility to hasten restoration.
Service vendors will
consider the priority levels of the TSP services supported by a multiple
service facility when determining the order of restoration. For example, a vendor should restore a multiple service facility supporting TSP services assigned restoration
priorities 1 and 2 before a multiple service facility
supporting TSP services assigned restoration priorities 3, 4, and 5. Service
vendors will use their best judgment to determine the restoration order
of multiple service facilities that support a number of TSP services with
a variety of restoration priority assignments.
As a matter of general
practice, service vendors should restore existing TSP services before
provisioning new TSP services. In resolving conflicts, the TSP Program requires
that restoration or provisioning of TSP services follow this sequence:
- Restore TSP services assigned restoration priority
- Provision Emergency TSP Services assigned provisioning
- Restore TSP Services assigned restoration priority
2, 3, 4, or 5
- Provision TSP Services assigned provisioning priority
1, 2, 3, 4, or 5
Preemption to Restore TSP Services
The TSP Program's rules authorize service vendors to preempt existing services to restore TSP
services when, in their best judgment, preemption is necessary. It is not necessary to secure prior consent of the service user who will lose service. However, the service
vendor will make its best effort to notify the user
of the preempted service and state the reason for,
and estimated duration of, the preemption
When the service vendor
determines that preemption is necessary (e.g., no
spare services are available), they may preempt non-TSP services. After ensuring a sufficient number of
public switched services are available for public
use, based on the service vendor's best judgment,
the vendor may use such services to satisfy a requirement
for restoring TSP services. If no suitable spare
or non-TSP services are available, the service vendor
may preempt an existing TSP service to restore a
TSP service with a higher priority-level assignment.
When this action is necessary, the service vendor
will select TSP services for preemption in the inverse
order of priority assignment.
