Installation Procedures
Step
1. Install telephone jacks at the extensions.
2. Connect each extension jack to the desired a/b slot on the Main Distribution Frame.
3. KS-type system telephones are preset at factory default for C/D pairs.
If you need to select a different C/D pair, see Figure 4-32 or Figure 4-34 then
program the new C/D interface assignment.
4. Install the telephone sets.
5. "Performing a Visual Inspection" on page 4-59.
6. Configure the required data (see "Operation" on page 6-1).
KS-type system telephones are powered through the C and D wires. Take the nec-
essary precautions to avoid short circuits at the interconnect block. If a short circuit
occurs between wires C and D, the interface's protection will take the extension out
of service. To reactivate the extension, remove the short, disconnect the system
telephone then reconnect it. The interface should start operating normally now.
