Getting Started

The 652 and 654 are 68302 microprocessor-based devices capable of transmitting 
data and voice. Both are shipped with 1MB of DRAM and 1.25MB of Flash 
memory, and have:

• an ISDN (RJ-45) connection; the 651 is a U interface and the 653 is S/T.

• two serial data ports; one async/sync V.24 interface with a DB25 connector, 

one async V.24 with an RJ45 connector.

• two POTS ports

This RJ45 serial data port is also used to connect to the integral 202/212
(V.23/21) modem. Power is supplied via an external DC power supply.
