1. Customer-supplied equipment.
2. RSTU2 or above is required for standard telephone message
waiting lamp.
3. U, S, T, R are ISDN reference model termination points.
4. PDKU and RDSU should only be used for 2000-series digital
telephones. They do not support all of the 3000-series digital telephone
features, including LCD. The PDKU also does not support BPCI, BATI
and the CTX Attendant Console.
