Description                                        

The TC1910 Ethernet Telephone Extender enables telephone service over a LAN via 10Base-T Ethernet connections.  It has a built-in Codec that digitizes voice and converts to packets for transmission between local and remote TC1910s with designated IP addresses. It is compatible with PBX and Key Systems (POTS).

LAN connections can be made by most types of Full Duplex Ethernet devices, including switches, routers, bridges, transceivers, etc. A Web-based Configuration user interface (most browsers including Microsoft Windows Explorer, etc.) is provided to view network settings or change IP addresses from the factory default.

Phone connection is automatic upon power-up or when network interruption is restored.  Depending on network traffic, multiple pairs of TC1910s can be used to set up individual point-to-point telephone links. A hardened temperature version (-20° to 70°C), Model TC1910T, is available for harsh environments.

The TC1910 provides Toll Quality sound within voice bandwidths from 300Hz to 3.4KHz. Two types of voice applications are supported: one, connecting to a PBX for outside telephone service; two, setting up a "hot link" point-to-point connection, e.g. between two work stations, within a LAN.  Two-wire FXS (foreign exchange subscriber) is provided on the telephone side with ring down capability and FXO (foreign exchange office) on the PBX side.

Eighteen LEDs for network status, phone status, power and volume are provided to enhance status monitoring and diagnostics. Dry contacts for external alarm and ringer are standard.

The TC1910 is available in standalone (TC1910S) or rack-mount (TC1910R) versions. The rack-mount versions fit into TCRM191 or TCRM195 19" Rackmount Card Cages. Power is 12VDC or 115/230VAC with an external power cube. 24VDC power is optional. Power redundancy is standard. Phone connectors are RJ-11 Female and 10Base-T connectors are RJ-45 Female.
