I, Ronald O. Brendengen, Chief Financial Officer of Commercial Power Finance,
Inc., the General Partner of Telecommunications Income Fund X, L.P., certify
that:

     1. I have reviewed this annual report on Form 10-K of Telecommunications
     Income Fund X, L.P.;

     2. Based on my knowledge, this report does not contain any untrue statement
     of a material fact or omit to state a material fact necessary to make the
     statements made, in light of the circumstances under which such statements
     were made, not misleading with respect to the period covered by this
     report;

     3. Based on my knowledge, the financial statements, and other financial
     information included in this annual report, fairly present in all material
     respects the financial condition, results of operations and cash flows of
     the registrant as of, and for, the periods presented in this annual report;

     4. The registrant's other certifying officers and I are responsible for
     establishing and maintaining disclosure controls and procedures (as defined
     in Exchange Act Rules 13a-15(e) and 15d-15(e)) for the registrant and we
     have:

               a) designed such disclosure controls and procedures, or caused
               such disclosure controls and procedures to be designed under our
               supervision, to ensure that material information relating to the
               registrant is made known to us by others, particularly during the
               period in which this annual report is being prepared;

               b) evaluated the effectiveness of the registrant's disclosure
               controls and procedures and presented in this report our
               conclusions about the effectiveness of the disclosure controls
               and procedures, as of the end of the period covered by this
               report based on such evaluation; and

               c) disclosed in this report any change in the registrant's
               internal control over financial reporting that occurred during
               the registrant's most recent fiscal quarter that has materially
               affected, or is reasonably likely to materially affect, the
               registrant's internal control over financial reporting;

     5. The registrant's other certifying officers and I have disclosed, based
     on our most recent evaluation of internal control over financial reporting,
     to the registrant's auditors and the audit committee of registrant's board
     of directors (or persons performing the equivalent function):

               a) all significant deficiencies and material weaknesses in the
               design or operation of internal control over financial reporting
               which are reasonably likely to adversely affect the registrant's
               ability to record, process, summarize and report financial
               information; and

               b) any fraud, whether or not material, that involves management
               or other employees who have a significant role in the
               registrant's internal controls.
