CO Line Interface Unit—An optional PCB (an older version of RCOU) that provides the system with four loop start CO lines. Supports Caller ID when used with RCIU/RCIS circuits.

Integrated Data Interface Unit—Replaces the normal digital telephone base so that the telephone can be used for the transmission and reception of data between a terminal/personal computer connected to the telephone and devices connected to other PDIU-DIs or to modems, printers, and computers which are in turn connected to PDIU-DSs. The PDIU-DI is also used to provide personal computer auto dialing of voice calls without a modem; and, access to outside dial-up data services and/or bulletin boards via modem pooling.
