Nortel BCM50 Configuration Manual page 187

Using telephones for special features
• send up to 30 messages to other system telephones.
• answer external calls on up to 112 lines on a KIM (120 lines on a legacy CAP), and extend
calls to other BCM50 telephones
• provide extra memory buttons for the 7316E digital phones
Telephones with KIMs that are not configured in system programming allow only memory button
programming on the modules. In this case, the KIM is known as an OKIM (ordinary KIM). There
is no specific limit for the number of CAPs using OKIMs for the system, except from a call
processing point of view.
