HSSI Data Port Physical Interface
FrameSaver Model 9520 has two HSSI data ports, and Model 9820-45M has one.
Monitor RTS
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
the RTS off 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.
Port (DTE) Initiated Loopbacks (9520)
Possible Settings: Local, Disable
Default Setting: Disable
Allows a local external DTE Loopback to be started or stopped via the port’s attached data
terminal equipment using the port’s interchange lead LL (ITU 141) for V.35, or LA (ITU
143) for HSSI.
Local – The DTE attached to the port controls the local external DTE Loopback.
Disable – The DTE attached to the port cannot control the local external DTE Loopback.

Port Status
Possible Settings: Enable, Disable
Default Setting: Enable
Determines whether the data port is being used and can be configured.
Enable – The port is active, and can be used to transmit and receive data.
Disable – The port is not active. When the port is disabled, the following will occur:
No alarms or traps configured for the port will be generated.
LED for the port will be held in an Off state.
No – The operation is canceled. (Pressing either the Esc or Ctrl-a key also acts as a
No.)
Yes – Port status is disabled.
