Mar 02, 2005 - Intended for SCADA & Process Control fiber optic redundant ring networks, a new 4-Channel Self-Healing Ring Multi-Drop Multiplexer from TC Communications features "Virtual Channel Mapping (VCM)."
Aug 26, 2004 - Integrated T1/E1/LAN connectivity over fiber is cost efficient with a new Ethernet & T1/E1 Fiber Multiplexer from TC Communications. The TC8510 multiplexes one-to-four T1/E1 channels and a 10/100M Ethernet over single mode or multimode fiber. Serial data channels are optional.
May 10, 2004 - Ideal for mission critical fiber optic networks, the new Redundant Ring Gigabit Ethernet Switch from TC Communications provides maximum reliability. If a fiber cable or device failure occurs, the data path automatically switches over within 250 msec. to the secondary path to maintain Ring network integrity. (Commercial Ethernet switches can require several minutes to recover after a network failure)
Jan 28, 2000 - The TC1900 "Quick-Talk" RS-232 or Fiber Telephone Extender can turn a fiber optic network or RS-232 circuit into a voice network simply by plugging a telephone set into an RJ-11 (or DB25) connector. It is compatible with most PBXs or Key Systems.
Sep 28, 1999 - The new TC2400 is a two-channel Multi-Drop Fiber Optic Modem specifically designed for self-healing ring fiber optic communications networks requiring high data rates.
Jan 22, 1998 - Featuring extensive diagnostics, optical/power redundancy and user benefits, the TC1680 T3 Fiber Optic Modem provides a point-to-point high speed data link between two DS3 devices. It is ideal for a variety of applications including extending the point of presence from Telco demarcation points, ATM nodes or linking T3 multiplexers.
Jan 22, 1998 - Featuring flexible interfaces and extensive diagnostics, the TC2200 is a Multi-Drop Fiber Optic Modem for interconnecting Remote Terminal Units (RTUs) or Programmable Logic Controllers (PLCs) in a Bus Topology. It is ideal for most Process Control Network applications including SCADA, Traffic Control and Security.
Sep 10, 1997 - The TC1540 is a highly versatile 2-Wire RS-485 fiber optic modem that can mix or match RS-232, RS-422 or RS-485 (2-wire & 4-wire) interfaces, as required. For example, a user could have a 2-Wire RS-485 interface on one end and RS-232, RS-422 or 4-Wire RS-485 on the other end. Two-wire RS-485 versions can be changed to 4-wire RS-485 by simply changing a DIP switch.
Aug 08, 1997 - A Windows-based management software module, 8 extra RS-232 data channels and sleek "1U" packaging head up a long list of features for the new TC8300 One-to-Four Channel Fiber Optic T1/E1 Multiplexer.
Jun 25, 1997 - An innovative "Multiple-Master" Self-Healing Ring configuration that can recover link failures in several places in the ring is now available with the TC Communications 8/12 Channel Fiber Optic Multi-Drop Multiplexer (Model TC2800).
