Vocality V100 Digital Voice Card (10, 24 or 30 Channels)
The Digital Voice Card presents the ultimate in integrated voice connectivity. Primary rate ISDN circuits can be terminated by a V100 via an E1/T1 interface, and protocol stacks switch and route calls throughout the Vocality network. The card can optionally compress up to 30 voice calls over the satellite link.
The card supports a wide range of industry standard ISDN signalling standards such as CCS (QSIG) depending on the type of interface selected, and as well as compressed voice circuits, the card also supports uncompressed ISDN data and a feature key enabled secure voice capability.
The basic Digital Voice Card has the ability to compress up to 10 voice circuits from an E1/T1 line, and up to 24/30 when fitted with the expansion daughterboard.
