Description

The PSC VODEC VXS-8 is a compact 1 unit 19 inch rack mount unit designed to allow subscribers to address PA/GA broadcast loudspeaker networks and to support up to eight discrete party line communication channels. Each VXS-8 shelf provides connection for up to sixteen handsets with cascade switching capability to maximum of 512 stations. The unit is connected to the host panel by locking quick release flat ribbon cable connectors which enable rapid installation/service.

VXS-8 consists of a robust enclosure which houses a single surface mount (SMD) P.C. style motherboard, fascia mounted LED status display array and rear panel plug/socket connectors. The page/party system handsets are connected to the VXS-8 switch by a noncritical standard 2 twisted pair 18 AWG minimum size shielded/ screened field cable. No special multi core cables are required with this system. Field cables are landed onto VXS-8 port which is equipped with screw terminations ribbon cable conversion to allow direct connection to the VXS-8 switch. VXS-8 incorporates VSOC (PSC VODEC system on a chip) technology that obviates conventional software based solutions. This eliminates possible latent software bugs, software license requirements, reboot/boot ups following supply brown outs and vastly improves EMC tolerance. The VXS-8 switch extends paging capability to all handsets, enabling single button address of PA/GA system loudspeakers on a “push to page“ release to party basis. Possible risk of acoustic feedback due to proximity of a PA/GA loudspeaker to a live sub-scriber handset is obviated, by either real time muting (RTM), or digital delay feed forward (DDF). VXS-8 obviates antiquated technology, mechanical rotary switches and instead, employs modern vandal resistant push button key pads, which have become commonplace on conventional telephone apparatus. The VXS-8 switch also allows subscribers to establish point to point selective telephone PBX style communications, in addition to the embedded eight party line connectivity. This maybe be implemented by incorporation of an automatic telephone switch either within the PA/GA system or as an interface to a PABX external to the PSC VODEC package.
