4-10 Data Port Configuration
Table 4-3. FR Interface Parameters (Cont.)
Parameter Remarks
Physical
Data Rate (Kbps) The operation rate of the port in kbps.
64, 128, 256...1792 Kbps (in intervals of 64 kbps)
CRC Specifies the CRC polynomial to be used for error detection by the data port.
CRC 16, CRC 32
Clock Polarity Specifies the relative clock polarity, for compatibility with user-equipment interface
characteristics
• Normal: Clock falling edge occurs in the middle of the bit interval
• Inverted: Clock rising edge occurs in the middle of the bit interval
Signaling
Protocol
Specifies the Frame Relay link control protocol to be used on the data port.
Note: The protocol must match the protocol used by the equipment connected to the
data port
If the CLLM status is active:
• No protocol is to be used
• CCITTQ933A: ITU-T Rec. Q.933, Annex A
• ANSIT1617D: ANSI T1.617, Annex D
• LMI specification
Signaling
Procedure
The Local In-Channel Signaling Procedure that is used.
• Not Applicable: if the protocol is None
• User to Net (Network side)
• User to Net (User side)
• Bidirectional
CLLM Status Indicates if the configuration supports CLLM (Consolidated Link Layer Management).
• Active
• Not Active: if the protocol is IMI
VC Signaling Information
This dialog is relevant only to DATA-FR port application when the Signaling Protocol
is other than none.
