| Emergency-response communications network International Communications announced new emergency-response Deployable Communications Network, DCN, designed to provide a rapidly deployable command post with four Iridium voice or data satellite channels tied into an integrated private branch exchange, PBX. The DCN will have optional hookups for connecting into GSM phones and Inmarsat high-speed data satcom channels. The system provides multiple-link management and can support multiple workstations inside the communication center. When used with the GSM phone option, the system provides a local-area virtual cell site. The handheld GSM phones can be used within a several-mile radius of the DCN center, connecting through the PBX into the Iridium back-haul lines for communication with the outside world. The HSD option uses Inmarsat Swift 64 service, offering a 64 kbps data channel, plus an additional voice circuit, cross-distributed and shared among all of the operator positions. The DCN is also compatible with Inmarsat's BGAN broadband service. The DCN is designed to provide a lightweight scalable commercial-off-the-shelf solution for first responders in regions where landlines and conventional cellular services are disrupted by natural disasters or terrorist attacks. It gives relief agencies and other first responders immediate voice and data links with the outside world until higher-bandwidth semi-permanent systems can be deployed into the theater of operations. The system can also support secure wireline terminals for NSA Type 1 secure voice and data up to 10 kbps per channel. write your comments about the article :: © 2006 Construction News :: home page |
