SCHEDULE 13D/A2

This constitutes Amendment No. 2 (the “Amendment No. 2”) to the statement on Schedule 13D filed on behalf of Julian Singer (“Mr. Singer” or the “Reporting Person”), dated and filed February 16, 2016 (the “Statement”), relating to the common stock, $0.01 par value per share (the “Common Stock”), of Concurrent Computer Corporation (the “Issuer”). The Issuer’s principal executive offices are located at 4375 River Green Parkway, Suite 100, Duluth, Georgia 30096. Unless specifically amended or modified hereby, the disclosure set forth in the Statement shall remain unchanged.

Item 3. Source and Amount of Funds or Other Consideration

Item 3 of the Statement is hereby amended and restated in its entirety as follows:

Mr. Singer is the managing member of JDS1, which was created pursuant to that certain limited liability operating agreement, dated as of October 12, 2012 (“the “Operating Agreement”). All of the Shares reported above were purchased by funds generated and held by JDS1. The aggregate amount of funds used for the purchase of the securities reported herein was approximately $4,403,379.00.

Item 4. Purpose of the Transaction

Item 4 of the Statement is hereby amended and restated in its entirety as follows:

As previously reported, on the Statement on February 16, 2016, the Reporting Person sent a letter (attached as Exhibit 99.1 to the Statement, the “February 16 Letter”) to the Board of Directors (the “Board”) of the Issuer. In the February 16 Letter, among other things, the Reporting Person (i) expressed his disappointment with the Issuer’s performance and his belief that the Issuer’s poor operational and financial results, and inability to generate profits, are the consequence of mismanagement, (ii) noted that it appears that the value of the Issuer’s assets significantly exceeds the current stock price of the Issuer’s common stock, (iii) recommended that the Issuer retain advisors to pursue sales of the Issuer’s assets in an effort to maximize stockholder value, and (iv) indicated that, if the Issuer fails to take actions necessary to maximize such value, the Reporting Person may seek representation on the Board.

As previously reported, on Amendment No. 1 to the Statement, dated February 29, 2016, the Reporting Person is engaging in further discussions with the Issuer and is considering seeking to replace the entire Board if the Board fails to take actions necessary to maximize the value of the Issuer.

The purpose of this Amendment No. 2, is to report that, since the filing of Amendment No. 1 to the Statement, the Reporting Person sent a letter (attached as Exhibit 99.2 hereto, the “March 11 Letter”) to the Board of the Issuer. On March 1, 2016, the Issuer adopted a Tax Asset Preservation Plan (the “Plan”). In the March 11 Letter, the Reporting Person requested that the Board confirm that the Reporting Person will not be considered an “Acquiring Person” under the Plan if and to the extent that the Reporting Person acquires additional shares of Common Stock such that the Reporting Person’s aggregate beneficial ownership does not exceed 19.9% of the outstanding shares of Common Stock. In addition to the foregoing, the Reporting Person has requested that the Issuer appoint the Reporting Person and Matthew Stecker to the Board.

Except in connection with the matters described in this Item 4 and as contemplated herein, Mr. Singer does not currently have any specific plans or proposals that relate to or would result in any of the actions or events specified in clauses (a) through (j) of Item 4 of Schedule 13D. Mr. Singer reserves the right to change plans and take any and all actions that Mr. Singer may deem appropriate to maximize the value of his investment, including, among other things, purchasing or otherwise acquiring additional securities of the Issuer, selling or otherwise disposing of any securities of the Issuer beneficially owned by him, in each case in the open market or in privately negotiated transactions or formulating other plans or proposals regarding the Issuer or its securities to the extent deemed advisable by Mr. Singer in light of his general investment policies, market conditions, subsequent developments affecting the Issuer and the general business and future prospects of the Issuer. Mr. Singer may take any other action with respect to the Issuer or any of the Issuer’s debt or equity securities in any manner permitted by applicable law.

Item 5. Interest in Securities of the Issuer

Item 5 of the Statement is hereby amended and restated in its entirety as follows:

(a) Mr. Singer, as managing member of JDS1, may be deemed to beneficially own 894,536 Shares, comprising approximately 9.7% of the outstanding Shares, based on 9,206,843 Shares outstanding as reported in the Issuer’s Form 10-Q filed on February 9, 2016.

(b) Mr. Singer has sole dispositive and voting power over all of the Shares reported on this Schedule 13D.

(c) JDS1 has effected the following transactions since the filing of the Amendment No. 1 to the Statement:

Date of Transaction	Number of Shares Purchased	Price Per Share
February 29, 2016	5,000	$5.40

In addition, on March 2, 2016, JDS1 closed Options (as defined below) with an exercise price of $5.00 and an expiration date of March 18, 2016 with respect to 148,500 underlying Shares.

(d) No Person other than Mr. Singer has the right to receive or the power to direct the receipt of distributions or dividends from, or the proceeds from the transfer of, the reported securities.

(e) Not Applicable.

Item 6.  Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer.

JDS1 is a party to the following put options (the “Options”) with respect to the Shares. With respect to each of the Options, the counterparty to the Option has, until the relevant expiration date, the exclusive right to cause JDS1 to purchase the underlying Shares at the relevant exercise price.

Number of Underlying Shares	Exercise Price	Expiration Date
30,000	$5.00	June 17, 2016
32,500	$5.00	September 16, 2016

Item 7. Material to be Filed as Exhibits.

99.1 Letter, dated February 16, 2016, from the Reporting Person to the Board of Directors of the Issuer (Filed as Exhibit 99.1 to the Statement filed by the Reporting Person with the Securities and Exchange Commission on February 16, 2016).

99.2 Letter, dated March 11, 2016, from the Reporting Person to the Board of Directors of the Issuer.

Attn: Mr. Steve G. Nussrallah

Chairman of the Board

Members of the Board of Directors (the “Board”):

As you are aware, I am, through JDS1, LLC (“JDS1”), the beneficial owner for securities law purposes of 894,536 shares of common stock (the “Common Stock”) of Concurrent Computer Corporation (the “Company”). Based on the amount of stock reported as outstanding in the Form 10-Q filed by the Company on February 9, 2016, such amount represents approximately 9.7% of the outstanding shares of Common Stock. JDS1 is also a party to certain “put options” (the “Options”) relating to the Common Stock, pursuant to which the counterparty to the relevant Option has, until the relevant expiration date, the exclusive right to cause JDS1 to purchase the underlying shares of Common Stock at the relevant exercise price. Neither I nor JDS1 is a part of a “group” within the meaning of Section 13(d)(3) of the Securities Exchange Act of 1934 with respect to the Company or the Common Stock.

On March 1, 2016, the Company adopted a Tax Asset Preservation Plan (the “Plan”).¹ I am writing to request that the Board (i) confirm, pursuant to Section 1(a)(v) of the Plan, that neither I nor JDS1 will be considered an Acquiring Person under the Plan and (ii) waive the application of the terms of the Plan, if and to the extent that I and/or JDS1 acquire shares of Common Stock such that my aggregate beneficial ownership of Common Stock does not exceed 19.9% of the outstanding shares of Common Stock (whether by purchase of shares of Common Stock, exercise of Options, or otherwise).

I would appreciate a response to the foregoing request at your earliest convenience. If you have any questions or if you would like to discuss, let me know. I look forward to hearing from you.

Sincerely,

/s/ Julian Singer

Julian Singer
