Certification Regarding Eligibility
To Apply for Worker Adjustment Assistance

In accordance with Section 223 of the Trade Act of 1974, as
amended ("Act"), 19 U.S.C. § 2273, the Department of Labor
herein presents the results of an investigation regarding
certification of eligibility to apply for worker adjustment
assistance.
The group eligibility requirements for workers of a firm
under Section 222(a) of the Act, 19 U.S.C. § 2272(a), are
satisfied if the following criteria are met:
(1) a significant number or proportion of the
workers in such workers' firm have become totally or
partially separated, or are threatened to become
totally or partially separated;
(2)(B)(i)(I) there has been a shift by the workers'
firm to a foreign country in the production of
articles or supply of services like or directly
competitive with those produced/supplied by the
workers' firm; OR
(II) there has been an acquisition from a
foreign country by the workers' firm of
articles/services that are like or directly
competitive with those produced/supplied by
the workers' firm; AND
(ii) the shift/acquisition must have contributed
importantly to the workers' separation or
threat of separation.

The investigation was initiated in response to a petition
filed on May 29, 2018 on behalf of workers of Sonus Networks,
Inc., Research and Development Division, a subsidiary of
Ribbon Communications Inc., including workers whose wages were
reported through Genband US LLC, Morrisville, North Carolina
(Ribbon). The workers' firm is engaged in activities related to
the supply of software research and development services.
During the course of the investigation, information was
collected from the workers' firm.
Section 222(a)(1) has been met because a significant
number or proportion of the workers in such workers' firm have
become totally or partially separated, or are threatened to
become totally or partially separated.
Section 222(a)(2)(B) has been met because the workers'
firm has acquired from a foreign country services like or
directly competitive with services supplied by the workers which
contributed importantly to worker group separations at Ribbon.
Conclusion
After careful review of the facts obtained in the
investigation, I determine that workers of Sonus Networks, Inc.,
Research and Development Division, a subsidiary of Ribbon
Communications Inc., including workers whose wages were
reported through Genband US LLC, Morrisville, North Carolina,
who are engaged in activities related to the supply of software
research and development services meet the worker group
certification criteria under Section 222(a) of the Act, 19
U.S.C. § 2272(a). In accordance with Section 223 of the Act, 19
U.S.C. § 2273, I make the following certification:
"All workers of Sonus Networks, Inc., Research and
Development Division, a subsidiary of Ribbon
Communications Inc., including workers whose wages were
reported through Genband US LLC, Morrisville, North
Carolina, who became totally or partially separated from
employment on or after May 25, 2017 through two years from
the date of certification, and all workers in the group
threatened with total or partial separation from employment
on the date of certification through two years from the
date of certification, are eligible to apply for adjustment
assistance under Chapter 2 of Title II of the Trade Act of
1974, as amended."
Signed in Washington, D.C. this 28th day of June 2018.
