TTI allows data modules without hardware translation to merge with an appropriate data module connected to a non-administered port. The non-administered port is given TTI default translation sufficient to allow a terminal connected to the data module (connected to the port) to request a TTI merge with the extension of a data module administered without hardware translation.
Note:
TTI is not useful for Announcement and X.25 hardware.
Administration Without Hardware supports PDM, TDM, Data-Line, Announcement, and X.25 data modules.
Note:
The 513 BCT has an EIA interface rather than a DCP interface (no built in data module, attachable telephone, or telephone features). The 513 BCT is not administered; only the data module to which the 513 BCT is connected is administered.
