C37.94 IP Gateway Card

C37.94-over-IP Gateway (TC3846-2)

Featuring extremely low latency of less than 5 msec., one way, the TC3846-2 C37.94-over-IP Gateway extends two C37.94 circuits over Ethernet/IP networks. It is simple to configure and supports both point-to-point and point-to-multipoint topologies.

Extremely low latency (minimal end-to-end processing delay) is achieved by using high-performance adaptive clock recovery, buffering and forwarding technology. To insure reliable communications, the TC3846-2 supports VLAN and QoS for packet prioritization.

Each C37.94 channel is independent and transparent to protocols and signaling used. Clear channel and octet aligned modes are supported.

Key features include Traffic Monitoring and Statistics, Network Time Server (NTP Server), Remote Firmware Upgrade and Temperature and Power Consumption Monitoring.

Setup, diagnostics, and management are accessed via Web, SNMP, Serial Console and Telnet. Diagnostics include LED indicators and local and remote loopback to assist with troubleshooting and maintenance.

The TC3846-2 interface card can fit into any available JumboSwitch housing option including 2S Standalone chassis and 1U/2U/4U card cages. Power supply options are 12VDC, 24VDC, -48VDC or 115/230VAC. Standard operating temperature is -20°C to +70°C and the extreme temperature version is -40°C to +80°C.
