 | | Special protocols (transparent software) are required in both the mobile and land earth stations to facilitate to the use of STU via Inmarsat. | | | In the case where the STU is being used on a cell phone or satellite phone your best option is to keep the phone in analog mode (a STU, not a STE) and locate the STU a good 6-12 feet away from the antenna. | | | If the STU is being used in a SCIF or secure facility a cell phone is supposed to be an excluded item, but it is simply amazing how many government people (who know better) forget to turn off their phone before entering controlled areas and thus cause classified materials to be compromised. |

| | Communication servers use secure data devices (STU IIIs) as the dial-up interface which are connected to Defense Information System Administration (DISA) routers allowing STU III users to access the SIPRNET. | | | The key for using a STU III telephone must be kept in a secured (locked) storage area unless being used. | | | STU IIIs restrict access to authorized users only by use of a Control Access List (CAL) that is loaded into the STU III at the note site. |

| | ATandT's trade-in prices on the new DOD contract for STU-IIIs with five-year extended warranties are $1,575 for the Surity 1100, for classified applications; $2,575 for the Merlin-compatible 1100; and $2,040 for the Surity 2100, for sensitive, non-classified applications. | | | "There are still a lot of first-generation STUs in the field, even though they lack the advanced features of our newer STUs," Agee said. | | | STU users can upgrade to higher data speeds and advanced technology by exchanging their old terminals for new ATandT Surity* Voice/Data Terminals with a five-year extended warranty at NSA pricing. |

| | PORTSCOM - Reserve Experience Provides Active Dividends |
| | PORTSCOM users typically use MTF, Perseus or Enable to create data, start up the Blast program using a predefined script, initiate a call through the STU-III, go secure and switch over to the data mode on the STU to start the file transfer. | | | This constantly evolving PORTSCOM system will continue growing to keep up with technology. | | | On the software front, the possibilities include a move to MS Windows, replacements for Enable or Blast, and applications to add new capabilities such as geography/almanac or ship identification programs. |

| | EETimes.com - Startup looks to commercialize powerful crypto technology |
| | Many STU vendors, using homegrown DSPs and other hardware, stood poised to unleash high-level encryption technologies on the commercial market earlier in the decade. | | | To date, none of the companies supplying STUs and related secure communications technologies to government customers has announced pending consumer-market versions. | | | But they were compelled to put those projects on hold when the government demanded a "back door" key that would allow it to decrypt any traffic for law-enforcement and national-security purposes. |
