Contingency Communications Parent Switch (CCPS). The CCPS consists of one FES shelter towing a 10-kilowatt diesel generator, and one LOS(V)X that can dismount one LOS(V)1. The connections between the FES and the LOS are by cable initially, since no SHF is supplied. The FES can be operator-controlled external to the shelter by a dismountable remote terminal, which can be configured as a workstation or a dismountable NMF (DNMF). The FES has packet switch capability, but without the gateway function; hence, no direct connections to adjacent corps or EAC. The packet switch provides ports for two LANs and six X.25 local hosts, plus one dial-in port. The FES provides full flood search capability via a downsize routing subsystem (RSS-D) and an SHF interface capability and a digital subscriber voice terminal (DSVT) in the truck. The line termination unit (LTU) provides modem/multiplex functions for the main local subscriber interface and is equipped with a rear terminal board to permit direct connections instead of the J-1077.

The LOS(V)X is similar to an LOS(V)3, except that the LOS(V)X's ultra high frequency (UHF) radios operate on three separate link connections to the FES (no multiplex) and all links operate on either band.

The CCPS provides service for a total of 117 wire line subscribers including eight defense switching network (DSN) and eight commercial analog trunks.

Additionally, the FES provides a fully functional, downsized RAU capability for up to 25 mobile subscribers as well as dismounted combat net radio interface (DCNRI) access for single-channel radio users.

The CCPS supports the brigade headquarters with parent node capabilities and provides local switching for the mobile subscriber and local wire subscribers with appropriate interfaces with CNR, commercial access, TACSAT, DSN, and packet switch. Figure 3-15 shows a typical CCPS deployment. The power subsystem is similar to the NC switch.

Contingency Communications Extension Switch (CCES). The CCES consists of one FES shelter towing a 10 kilowatt generator, one dismounted LOS(V)1 with one radio with Band 1 and Band 3 capabilities, and one cargo high mobility multipurpose wheeled vehicle (HMMWV) with cargo trailer. Figure 3-16 shows a typical CCES.

The CCES provides the same wire, mobile and DCNRI capabilities as the CCPS; however, the quantity of LTU's limits wire access to 47 subscribers including eight DSN and eight commercial analog trunks.

Dismounted Extension Switch (DES). The DES provides access for 16-local wire subscribers with access to over 10 digital encrypted trunks to the MSE network via LOS or TACSAT. The DES consists of one of the two SB-4303s that populate a SEN switch.
