Threshold
00 to 100
Threshold for CLP=1 cells to be
discarded on the ingress/egress path.
Ring Selection Auto
Auto
Ring 16
Ring 17
Card will automatically select traffic from
the ring direction with the best signal.
Card will receive traffic from Ring 16
direction.
Card will receive traffic from Ring 17
direction.
Transmit Timing
Source
Local Received
Local
The Tx clock (and data rate) is the same
frequency as the RX clock and data rate,
(receive clock is looped to the
transmitter).
The on-board crystal oscillator in used for
the clock source and will not equal the
receive clock frequency.
Line Type
(CRS ONLY)
M23
Cbit Parity.
M23
ANSI T1.107a-1989
Cbit Parity
Asynchronous, M23 multiplex format,
PM parameters based on P-Bit Parity
Errors (PE).
Synchronous T3, M13 multiplex format,
separate PM parameters based on P-Bit
Parity Errors (PE) CRC violations.
Loopback Config. None None
Terminal
Facility
Payload
No loopback activated on this card.
Sends cells back to the cellbus and back
out to the ring. No changes are made to
the path layer data.
Loops the incoming signal back to the
CPE and generates AIS to the cellbus.
Loops the signal back to the CPE AFTER
framing is performed and before being
converted to ATM cells.
Far End Loopback None None
Payload
Reset
Line
No loopback has been requested for far
end.

Resets a loopback at the far end.
Requests a loopback for the line at the far
end.
Circuit Identifier <blank>

characters, up to 20.
User defined. Usually describes the traffic
or customer, slot, and port.
Line Coding B3ZS <none>
This field is not configurable, display
only.
Line Build Out Off Off / On Sets the signal level to compensate for the
distance between the system and the
interfacing equipment.
