System Configuration and Operation Using the Broadcast Option
3.15.6 Release
Pressing the “R” command allows you to release the circuit from the data test equipment. The
system will verify the action desired with a yes/no question.
With the Release Circuit, the Data Test Center removes the connection between the circuit
being tested and restores the circuit to its preaccessed state.
Figure 3-55 shows the TADS screen with the release verification.

3.15.7 Terminate and Leave Access
The Terminate and Leave Access (TLA) circuit gives the data test center the capability to
termiante one or both directions of transmission on a circuit by inserting an unassigned
channel code (01111111) in the outgoing transmission path(s). The TLA feature is useful in
circuit provisioning to turn circuits up and down remotely, and in testing multipoint circuits to
isolate and remove noisy bridge legs from service.
Figure 3-56 shows the TLA screen with the choice of Monitor (
mon
) or Unassigned Channel
Code (uca) to be applied to the highlighted circuit. (If TLA had been applied to a Split circuit,
the choices would have been
spl
or
uca
.)
