Sec. 52.103  Lag times.

    (a) Definitions. As used in this section, the following definitions 
apply:
    (1) Assigned Status. A toll free number record that has specific 
subscriber routing information entered by the Responsible Organization 
in the Service Management System database and is pending activation in 
the Service Control Points.
    (2) Disconnect Status. The toll free number has been discontinued 
and an exchange carrier intercept recording is being provided.
    (3) Lag Time. The interval between a toll free number's reservation 
in the Service Management System database and its conversion to working 
status, as well as the period of time between disconnection or 
cancellation of a toll free number and the point at which that toll free 
number may be reassigned to another toll free subscriber.
    (4) Reserved Status. The toll free number has been reserved from the 
Service Management System database by a Responsible Organization for a 
toll free subscriber.
    (5) Seasonal Numbers. Toll free numbers held by toll free 
subscribers who

do not have a year-round need for a toll free number.
    (6) Spare Status. The toll free number is available for assignment 
by a Responsible Organization.
    (7) Suspend Status. The toll free service has been temporarily 
disconnected and is scheduled to be reactivated.
    (8) Unavailable Status. The toll free number is not available for 
assignment due to an unusual condition.
    (9) Working Status. The toll free number is loaded in the Service 
Control Points and is being utilized to complete toll free service 
calls.
    (b) Reserved Status. Toll free numbers may remain in reserved status 
for up to 45 days. There shall be no extension of the reservation period 
after expiration of the initial 45-day interval.
    (c) Assigned Status. Toll free numbers may remain in assigned status 
until changed to working status or for a maximum of 6 months, whichever 
occurs first. Toll free numbers that, because of special circumstances, 
require that they be designated for a particular subscriber far in 
advance of their actual usage shall not be placed in assigned status, 
but instead shall be placed in unavailable status.
    (d) Disconnect Status. Toll free numbers may remain in disconnect 
status for up to 4 months. No requests for extension of the 4-month 
disconnect interval shall be granted. All toll free numbers in 
disconnect status must go directly into the spare category upon 
expiration of the 4-month disconnect interval. Responsible Organizations 
shall not retrieve a toll free number from disconnect status and return 
that number directly to working status at the expiration of the 4-month 
disconnect interval.
    (e) Suspend Status. Toll free numbers may remain in suspend status 
until changed to working status or for a maximum of 8 months, whichever 
occurs first. Only numbers involved in billing disputes shall be 
eligible for suspend status.
    (f) Unavailable Status. (1) Written requests to make a specific toll 
free number unavailable must be submitted to DSMI by the Responsible 
Organization managing the records of the toll free number. The request 
shall include the appropriate documentation of the reason for the 
request. DSMI is the only entity that can assign this status to or 
remove this status from a number. Responsible Organizations that have a 
toll free subscriber with special circumstances requiring that a toll 
free number be designated for that particular subscriber far in advance 
of its actual usage may request that DSMI place such a number in 
unavailable status.
    (2) Seasonal numbers shall be placed in unavailable status. The 
Responsible Organization for a toll free subscriber who does not have a 
year round need for a toll free number shall follow the procedures 
outlined in Sec. 52.103(f)(1) of these rules if it wants DSMI to place a 
particular toll free number in unavailable status.
