Configuring Serial Ports with DCEs 75
3 Set the baud rate (56 or 64 kbps) for the DS0 channel using:
SETDefault !<path> -PATH T1DSoChnlBaud = <FT156K|FT164K>
4 Set the path clock using:
SETDefault !<path> clock = [Internal | External]
5 Re-enable the path using:
SETDefault !<path> -PATH CONTrol = Enabled
The following optional settings are also available:
■ T1FrameMode
■ Superfame (SF)
■ Extended Superframe (ESF)
■ T1LineCoding
■ Binary with 8 zero substitution (B8ZS)
■ Alternate Mark Inversion (AMI)
■ Alternate Mark Inversion with bit 7 zero code substitution

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
