Please click here to subscribe to Secure IP VTC service.
If you are interested in ISDN VTC service, please read the information below, and contact the DISN Global Support Center (DGSC) for instructions on how to proceed.
Due to the limited number of Integrated Services Digital Network (ISDN) resources currently available to existing DVS-G users, DISA NS24 (the DVS Program Management Office [PMO]) has determined that new ISDN subscribers will be determined on a strict case-by-case basis and, in most cases, will only be authorized using a "one-in, one-out" policy whereby the DVS business office will have to identify an existing site to be removed for every new subscriber proposed. For example, a prospective EUCOM site requesting ISDN service might be approved if another EUCOM site is discontinuing its service.
