Installing CP cables for BITS
Install control processor BITS cables between a CP-with-BITS and the BITS
termination panel.
Prerequisites
• Use the appropriate cable for your configuration. Refer to the
241-7401-200 Passport 7400 Hardware Description for a list of cable
product codes and specifications.
• Ensure you have routed and labeled the CP cable.
• The BITS termination panel provides the necessary terminations
(DS1/E1 balanced or E1 unbalanced) for the CP-with-BITS.
Procedure steps
1 Set the dip switch on the BITS termination panel to “single cp” or “dual cp”
depending on whether you are connecting the termination panel to one
control processor or to two redundant control processors.
2 Connect the BITS cables to the output ports on the BITS termination
panel and tighten the screws. See the figure “Connections for CP-with-
BITS” (page 266)
3 Connect the other end of the cables to the DS1/E1 BITS ports on the
faceplates of the main and spare CPs. See the figure “Control processor
with BITS faceplate” (page 267)
CAUTION
Risk of equipment damage
To avoid damaging equipment, always connect the cable
to the termination panel before you connect it to the
control processor.
