While the Alpha-Mate is properly a DTE, it is pinned out as a DCE. The Alpha-Mate has a built-in
modem that normal would be used for telephone connection to a modem in the paging terminal. The
Alpha-Mate's serial port pin-out allows it to plug into a paging terminal in place of an external
modem.

The Equatorial interface box has signal pins like a DTE but has a female DB-25 connector like a
modem.

TNPP Satellite Option, Part No. 950-9347.
In Table 16, the connector codes map to the pinouts shown in Figure 28. In the column
headers of Table 16, the signal name in quotes is the label as it appears on the Zetron
schematics. The colors are those of the wires in the RJ-12 jack.
