Configuring Serial
Ports with DCEs
This section describes how to configure the serial ports with modems,
CSU/DSUs, or ISDN TAs attached.
Before beginning this procedure, complete the following tasks:
■ Cable the serial port and connect it to the telephone network.
■ Log on to the system with Network Manager privilege.
The serial port automatically detects the following settings:
■ Line type — dial-up or leased
■ Clock — external
■ Connector type — RS-232, V.35, X.21, RS-449, or RS-530
ISDN TAs If you are attaching an ISDN TA, you must configure the TA with the
SPIDs, switch type, local telephone numbers, and Multilink PPP options
