58 -- Transisition Switch Module

The Marine Corps Systems Command (MARCORSYSCOM) is in the planning stage of a procurement for the replacement for its current Unit Level Circuit Switch (ULCS) equipment. The Transition Switch Module (TSM) will provide commercially available circuit switching technology to replace the aging TRI-TAC family of equipment (AN/TTC-42 and SB-3865). It will provide all of the services currently available in USMC switching equipment in a smaller, lighter package. Additionally, the TSM will provide enhanced multiplexing capabilities and an Integrated Services Digital Networks (ISDN) capability. The TSM will provide a flexible Unit Level Switch capability that bridges legacy TRI-TAC switches with current commercial technology to provide Marine maneuver elements with more robust voice/data switching, data transport, and bandwidth management capabilities. The TSM is anticipated to be a three transit case solution that will be fielded to all units that currently have a circuit switching capability (Marine Expeditionary Force (MEF) and Major Subordinate Command (MSC) through Regiment). To facilitate planning efforts, a DRAFT copy of the Statement of Work and Performance Soecification has been posted to MARCORSYSCOM's web site at http://.marcorsyscom.usmc.mil/sites/ctq/tsm.asp for comment. Interested parties should submit written comments to the following address: COMMANDER, MARCORSYSCOM, 2033 Barnett Ave., CODE CTQIDP, ATTN: Ira D. Patterson, Quantico, VA 22134-5010
