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 Ethernet devices, including switches, hubs, 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. An
extreme temperature version (-20°C to +70°C), Model TC1910-T, is available for harsh environments.
The TC1910 provides Toll Quality sound within voice bandwidths from 300Hz to 3.4 Khz. 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 ex-
change office) on the PBX side.
The TC1910 also supports one channel of two or four wire analog signal. The analog interface is for FSK
(frequency shift key) applications. The analog interface has a 600 ohm isolation audio transformer. The
analog voltage can be 0 to 3 Vpp.
Eighteen LEDs for network status, phone status, power and volume are provided to enhance status monitor-
ing and diagnostics. Dry contacts for external alarm and ringer are standard. The TC1910 is available in
standalone (TC1910S) or rackmount (TC1910R) versions. Power is standard 12VDC with optional 24VDC
or 115/230VAC with an external power cube. Power redundancy is standard. 10Base-T connectors are RJ-
45 Female and Phone connectors are RJ-11 Female
