Lockout (Line, Link, or Receiver)
Summary: Sometimes it may be necessary to temporarily lock out a bad line, link, or receiver for testing
purposes, or until replacement modules or parts can be installed. To do this in TCIV proceed
as follows:
Line Lockout
Step 1. Set the line’s A: attributes 1
thru
7 off. This signals the TCIV CPU to minimize its response
to inputs from these lines. Inputs include call-in, or off-hook service requests. This lockout is
never 100% since the CPU must keep scanning these lines and intrepreting the blank attrib-
utes.
Step 2. Attempt to use the line and verify it is locked-out. Note: This lockout will not work if the line
has a defect that allows it to respond to incorrect physical number addressing.
Link Lockout
Step 1. Refer to the Programming Section and program Location Code 64196 to lockout any one or
more of the 16 links.
Note: If all 16 links are locked out, a computer will be needed to restore service to the
system.
Step 2. Press the Reset button on the CPU. The lockout only takes effect after resetting.
Receiver
Refer to the Programming Section and program Location Code 64012 (DTMF time) to lockout
Lockout
a defective receiver temporarily. The system can function with only one receiver until repairs
are made.
