The connector pin assignment described in Table C-14 shows signal and pin

Service Modem Connections
The ARN back panel contains one modem service interface, labeled Modem; its
DB-9 plug connector provides an RS-232-D serial connection. You use this local
console port to connect the ARN to any Hayes compatible modem for remote
dial-in access.
The Passport ARN shipping package includes the console/modem kit
(Order No.110310) for connecting devices to the Modem port. To connect a
modem, use the cable (Order No.110307 from the kit), a standard, 15-foot molded
AT serial cable with DB-9 receptacle to DB-25 plug connectors.
