This controlled-access requirement requires a DITCO Basic Agreement to access attachments; access requests must include the requestor’s UEI or CAGE code and will be rejected without it, and if not approved/rejected within 24 hours, the listed DISA contact should be emailed. The combined synopsis/solicitation under FAR Part 12 is the only solicitation and seeks quotes for commercial telecommunications services; it is not set aside for small business. Offerors should quote monthly recurring and/or non-recurring charges, with CLIN descriptions, quantities, and units of measure per the IQO Deskbook. Evaluation will use lowest price technically acceptable, under NAICS 517111 and PSC DG11. Requirement details, place of performance, POC information, and evaluation specifics are in the attachment, and the solicitation is also downloadable via IDEAS.
