Connect Across Unified Communications Networks

The Cisco VG30D Voice Gateway facilitates simple and cost-effective networking among digital telephony interfaces, including:

  • ISDN Primary Rate Interface (PRI)
  • QSIG
  • Digital Private Network Signalling System (DPNSS)

Easy Integration

The Cisco VG30D Voice Gateway transparently integrates with other Cisco Voice Gateways and IP telephony networks.

The Cisco VG30D Voice Gateway converts the DPNSS protocol to and from the Q.931 or QSIG protocol on E1 digital interfaces. It supports basic call interworking, including simple services such as calling and connected identity, between DPNSS and Q.931 or QSIG.

The Cisco VG30D Voice Gateway also supports the mapping of advanced DPNSS supplementary services to and from QSIG.

Works with Cisco Call-Processing Systems

The Cisco VG30D Voice Gateway operates with other Cisco Voice Gateways to connect Cisco Unified Communications Manager and Cisco Unified Communications Manager Business Edition to DPNSS networks.
