The 25B/108 Data Linc Extender is a low-cost data set that extends
teletypewriter or data circuits
to a subscriber location, eliminating requirements for DC pulses over
metallic local loop circuits.
The unit is a two-section module consisting of a transmit and a receive
branch, which together
provide one duplex data communication channel. The 25B/108 converts
asynchronous, low-level
binary signals to a frequency-shift output for transmission over
voice-frequency facilities at rates of
up to 300 bits per second.


similar to a WECO 103-C
