station port. If the Caller ID device is to be located next to a PARTNER 
telephone, an additional wire pair will be needed to extend the line 
connection to the location where the PARTNER telephone is installed.
To install a Caller ID device for Line 1, do the following:
1. Remove the line 1 cord from the PARTNER line 1 jack on the 
processor module and install a 267A2 bridging adapter into the line 
1 jack.
2. Plug the line 1 cord (that was disconnected in step 1) into one of the 
jacks on the bridging adapter.
3. Plug the line 1 extended cord (the cord corresponding to the 
additional wire pair running to the location by the PARTNER 
telephone) into the other jack on the bridging adapter.
4. At the location where the Caller ID device is being installed, plug the 
other end of the line 1 extended cord into the Caller ID device. If the 
device has 2 jacks, plug the cord into the jack labeled LINE.
5. Plug in the power cord (if one exists) for the Caller ID device.
