Data Port Configuration 4-5
4.5 Data Port Configuration
The data port is a synchronous serial port with a DCE interface. The interface type
is user-configurable: RS-530, V.35, V.36 or X.21. (The physical adaptation is made
by adapter cables.) The data port can be configured to operate at rates of
n × 64 kbps in the range of 64 to 2048 kbps.
The service type is user-configurable:
• Transparent transmission of serial data stream
• Frame Relay service for connection to Frame Relay equipment. Up to
8 DLCIs are supported. The user can select between service interworking per
FRF.8 and network interworking per FRF.5.
Basic tasks include viewing and configuring:
• Data port application
• Data FR application mode
• AAL1 Stream application mode.
Data Port Application
The Data port application determines the operation mode of the port (either
Frame Relay or AAL1 Stream).
