Adding DEFINITY ProLogix Solutions to Existing DCS
Networks
If your company has an existing DCS network of multiple systems, DEFINITY ProLogix Solutions can be
added to this network using either TCP/IP or ISDN-PRI D-channel signaling. If all the nodes in the DCS
network use the same type of connectivity — either all TCP/IP or all ISDN-PRI — then the new sites can be
added directly. If you wish to mix ISDN-PRI and TCP/IP connections in the network, then the new
DEFINITY ProLogix Solutions must connect to the network via a gateway system, which provides
conversion between TCP/IP and ISDN-PRI signaling. If there are nodes in the network using BX.25
signaling, the gateway system must be a DEFINITY ECS si or r model. If only ISDN-PRI and TCP/IP
signaling is used in the network, a DEFINITY ProLogix Solutions could be used as the gateway. Figure 6
shows a DCS network with a systems using all three types of signaling connected via gateways.
