T3 Rate Converters, AC


Please call 877-877-2269 for a replacement product or part.
Extended Double Diamond™ Warranty Available (3 Additional Year)


Take what's fast and make it faster.
If you want to take interface conversion to extreme speeds, this Rate Converter can connect your 10-Mbps Ethernet or 100-Mbps Fast Ethernet equipment to a single-channel 44.746-Mbps T3 service!

A built-in Ethernet bridge with VLAN support enables virtual LAN connections. The Rate Converter performs frame filtering and forwarding at the rate of 150,000 frames per second, and the bridge causes no LAN delays.

The T3 Rate Converter provides full control over multicast and broadcast messages. Autonegotiation enables a plug-and-play Ethernet connection without any additional configuration.

Front- and back-panel LEDs indicate Alarm Indication Signal (AIS) and Loss of Signal (LOS) line conditions and provide information and status of the Ethernet/Fast Ethernet link. Clocking either can be received from the T3 line or done internally by the converter's oscillator.
