Connecting An Asyn Interface

6.1.1.1 Connecting An Asyn Interface Module to A
Modem
As a DCE equipment, the modem has two kinds of serial interfaces: DB9F and DB25F.
Connecting the asyn interface to Modem
The asyn cable with 1-to-8 crystal connector converts the 68-pin connector of the asyn
interface into eight RJ45 connectors, and then connects to the DB25F interface of the
modem through the RJ45(crystal jack)-DB25 male converter.
When the asyn cable with 1-to-8 crystal jack is used, use a straight netwok cable to connect
the converter cable of the asyn interface module to the converter adapter.
This mode applies to such modules as NM-8A/16A and SIC-8A.
