Cisco VG30D Voice Gateway User Guide
This guide describes the hardware configuration and management of the Cisco VG30D Voice Gateway product, its installation, maintenance, and general operation. It is intended for trained personnel familiar with SCN protocols and their network topology. The Cisco VG30D Voice Gateway is a dual-port ISDN unit that is designed to perform signalling and service reconciliation between two unlike ISDN signalling systems. It typically gets deployed to attach the following: A QSIG (or DPNSS) PBX to a DPNSS (or QSIG) network, or several DPNSS PBXs to a QSIG or Q.931 backbone network (VoIP or ATM, for example), or a DPNSS PBX to a Q.931-based Public ISDN service (such as ISDN 30e). Suggest ways Cisco technical documentation can be improved and better serve your needs.

When you attach a QSIG (or DPNSS) PBX to a DPNSS (or QSIG) network, the Cisco VG30D Voice Gateway provides seamless service interworking between the attached PBX and other PBXs in the network, including interoperation of most of the commonly used services.
