4-Wire Modem Over IP | |
 | |
Flexible Serial Data Extensions over Packet Networks | |
| The IP•Tube SER 202T has integrated Bell 202T modem interfaces that connect to the Bell 202T 4 Wire modem interface of Data Communication Equipment and transports their serial communication over IP Packet networks. This conversion facilitates a cost effective path for Utility and Pipeline industries to migrate their SCADA communication from end of life analog circuits to Ethernet based LAN/WAN/MAN wired and wireless networks. | |
| Asynchronous Serial Over IP Asynchronous characters with 5 to 8 data bits, a baud rate 1.2 kilobits, 1 or 2 stop bits, and with or without parity are efficiently encapsulated into IP packets. The latency is controlled by setting the maximum number of consecutive async characters per IP packet. | |
| SCADA Protocol Transparency The IP•Tube SER 202T transports asynchronous SCADA protocols transparently because of its unique TDM circuit emulation capability. RTU transmit data is encapsulated into IP packets at 64,000 samples per second and de-encapsulated at the far end at the same rate, ensuring proper RTU receive data delivery. Multiple RTUs can be IP multiplexed onto T1 circuits for routing to existing cross-connect and channel bank equipment. | |
| IP•Tube SER 202T Standard Features | |
Dual LAN Interfaces Assured Delivery Protocol In order to assure high quality communications over links with intermittent or noisy performance, such as Wireless, the IP•Tube SER 202T employs Engage’s robust Assured Delivery Protocol with the following benefits: • Packet out of sequence detection and re-sequencing • Duplicate skipping • Lost packet retransmissions with configured delay | |
| IP•Tube SER 202T Optional Features | |
| Protector OPTION -PRO The protector option utilizes the second LAN interface as a redundant path for the interconnection of the IP encapsulated SER 202T data. The extension of the SER 202T has a fault tolerant link that is configured to always on, or with switch over criteria. |
