Overview         

The TC1900 "Quick-Talk" Telephone Extender can turn an RS-232 circuit into a voice network simply plugging a telephone set into an RJ-11 connector.

The TC1901 "Quick-Talk" is typically used to extend dial-up phone service to remote sites over a fiber optic network simply plugging a telephone set into an RJ-11 connector.

It is compatible with most 2-wire analog PBXs or Key Systems. Quick-Talk is typically used to extend dial-up phone service to remote sites over a fiber optic and/or RS-232 circuit. It provides 2-wire FXO on the telephone side and FXS on the PBX side. Because it digitizes the analog voice signals (converts them to PCM), voice quality does not degrade over extended distances.

The TC1910 is intended to provide flexible point-to-point telephone service via Ethernet Networks. It is often used by maintenance or service personnel in Campus, Traffic Control, or Utility Substation Networks.

The TC8520 multiplexes various combinations of 2-Wire Analog POTS; RS-232, RS-422, TTL or Dry Contacts; and, one channel of 10/100 Ethernet over single mode (1300/1550nm) or multimode (1300/1550) fiber.  It supports distances to more than 100km and offers a "two-way, one fiber" option to maximize fiber cable usage.  Optional redundant power and optics include automatic switchover in the event of a cable or device failure for maximum reliability.

The TC8800 is a 4-to-28 channel Telephone/Data Fiber Optic Multiplexer. It is often used to extend telephone lines in campus networks over fiber optics. In some instances, it can be used to replace expensive channel banks.
