Emergency Telephone Installation
You can use the emergency telephone to make calls when there is no power to the Business
Communications Manager system.
To install an emergency telephone on the Business Communications Manager system, connect a
single line analog telephone to the auxiliary port on the CTM. When you make a call from the
emergency telephone, the auxiliary port uses the telephone line connected to the Line 1 port of the
CTM.
Use the following steps to install the emergency telephone.
1 Connect a single line analog telephone to the auxiliary port on the CTM.
2 Connect an analog PSTN line cable to the Line 1 port of the CTM.
