OPTIONS DEFINITIONS
Unlocked Enables or disables card for service,
respectively.
Locked
0 to 100
Threshold for CLP=1 cells to be
discarded on the ingress/egress path.
Auto Card will automatically select traffic from
the ring direction with the best signal.
Ring 16 Card will receive traffic from Ring 16
direction.
Ring 17 Card will receive traffic from Ring 17
direction.
Received The Tx clock (and data rate) is the same
frequency as the RX clock and data rate,
(receive clock is looped to the
transmitter).
Local The on-board crystal oscillator in used for
the clock source and will not equal the
receive clock frequency.
M23 Asynchronous, M23 multiplex format,
PM parameters based on P-Bit Parity
Errors (PE).
ANSI T1.107a-1989 Synchronous T3, M13 multiplex format,
Cbit Parity separate PM parameters based on P-Bit
Parity Errors (PE) CRC violations.
None No loopback activated on this card.
Terminal Sends cells back to the cellbus and back
out to the ring. No changes are made to
the path layer data.
Facility Loops the incoming signal back to the
CPE and generates AIS to the cellbus.
Payload
Loops the signal back to the CPE AFTER
framing is performed and before being
converted to ATM cells.
None No loopback has been requested for far
end.
Requests a Payload loopback for far end.
Payload
Resets a loopback at the far end.
Reset
Requests a loopback for the line at the far
Line end.
Any alphanumeric User defined. Usually describes the traffic
characters, up to 20. or customer, slot, and port.
<none> This field is not configurable, display
only.
Off / On Sets the signal level to compensate for the
distance between the system and the
interfacing equipment.
