Introduction
There are two versions of the 8510 and 8528 display terminals with ADM. One
version of these two terminals provides the standard 25-pin asynchronous EIA-
232 interface. The other version of both of these terminals provides the standard
25-pin asynchronous EIA-232 interface, along with an additional interface called
the Telephone Multimedia Interface (TMI). The 8510 and 8528 display terminals
currently support TMI; the 8520 display terminal, on the other hand, does NOT
support TMI. The TMI is a round 8-pin connector used with special purpose
equipment. If present, it is located to the left side of the
EIA-232 connector (Figure 1-1).

The TMI is typically used for connecting video equipment for video telephone
applications. Although equipment can be connected to both the EIA-232
interface connector and to the TMI connector, simultaneous operation of both
interfaces is precluded. Actively operating TMI equipment has priority over EIA-
232 equipment. That is, when the TMI equipment is active, none of the data
operations described in this manual will work.
