3.0 OPERATION
Data is transferred from the system to the tail using the system receive
clock, which is provided to the external clock input (terminal timing) of the tail
device. Data from the tail circuit is loaded into the 3004-MTE buffer using the
receive clock of the tail device. Data is transferred from the 3004-MTE buffer to
the system using the system transmit clock.
4.0 INSTALLATION
Connect the port of the 3004-MTE labeled "SYSTEM" to the main modem
or multiplexer sub-channel, i.e. the "system DCE".
Connect the port of the 3004-MTE labeled "TAIL" to the local tail-end DCE
or modem, i.e. the "tail-end DCE". The local tail-end modem must be set to
EXTERNAL CLOCK. (Local modem must accept TD data on the Terminal
Timing signal from the 3004-MTE.)
Note: The remote modem on the tail circuit must be configured for Receive
Recovered Clock (clock loopback).
