Installing a BITS wire
Install a BITS wire from the site timing source to the BITS termination panel.
Prerequisites
• Test the signal strength at the end of the connection from the site source
before connecting. The signal strength must be within the range indicated
in ITU-T G703 or ANSI TI.102.
• If the signal is not within the range, fix the problem between the point of
test and the site source. Depending on the length of cable from the site
source, you may need a thicker gauge cable to ensure the signal strength.
Procedure steps
1 If they are not already connected, connect the BITS wires to the external
timing source.
2 At theBITS termination panel plug the connector (D-sub or coax) of the
timing wire (which you may have labeled as reference 0) into the
connector beside the label BITS 0 Rx. This wire will correspond on
Passport to the BITS 0 source and will be associated with the EE1/0 or
the EDS1/0 component.
3 For a redundant timing setup, plug the connector (D-sub or coax) of the
timing wire (which you may have labeled as reference 1) into the
connector beside the label BITS 1 Rx. This wire will correspond on
Passport to the BITS 1 source and will be associated with the EE1/1 or
the EDS1/1 component.
