Paradyne CSU, DSU, 9126 Data Port Physical Interface Options 3, Monitor RTS Control, Monitor DTR

4. Configuration Options

Table 4-7. Data Port Physical Interface Options (3 of 5)

Monitor RTS (Control)

Possible Settings: Enable, Disable

Default Setting: Enable

Specifies whether the state of the Request To Send (RTS) circuits on the user data port will be used to determine when valid data communication is possible with the DTE. When this condition is detected, CTS is deasserted, LMI is declared down, and no further transfer of frame relay data can occur on this interface.

Enable – Interchange circuit CA (ITU 105) – RTS is monitored to determine when valid data communication is possible with the DTE.

Disable – RTS is not monitored. RTS is assumed to be asserted and data is being transmitted, regardless of the state of the lead.

Monitor DTR

Possible Settings: Enable, Disable

Default Setting: Enable

Specifies whether the state of the DTE Ready (DTR) circuit on the user data port will be used to determine when valid data communication is possible with the DTE. When this condition is detected, an alarm is generated, LMI is declared down, and no further transfer of frame relay data can occur on this interface.

Enable – Interchange circuit CD (ITU 108/1/2) – DTR is monitored to determine whether data should be transmitted to the DTE.

Disable – DTR is not monitored. DTR is assumed to be asserted and data is being transmitted, regardless of the state of the lead.
