Parameter Function Values
Jitter Buffer Specifies the value of the jitter buffer
to be used on this pseudowire.
You should use the shortest feasible
buffer, to minimize connection
latency.
This parameter is not displayed for
HDLCoPSN pseudowires
The allowed range depends on the framing
mode:
FRAMED: 2500 to 200000 μsec, in 1-μsec
steps.
UNFRAMED: 500 to 200000 μsec, in 1-μsec
steps.
Default: 2500
Far End Type Specifies the type of framing used by
the equipment at the destination
endpoint. The selected value also
determines the encoding law used on
PCM voice channels.
Make sure to select the same value at
both end points. The selected value
must also match the Line Type
configured for the physical port of
the pseudowire local endpoint (see
the
Configuring Internal DS1 Port
Timeslot Utilization
section)
This parameter is not displayed for
HDLCoPSN pseudowires
E1 – E1 stream with G.704 framing. The PCM
signals are processed assuming that they are
encoded in accordance with the A-law. You can
use this selection when the port Line Type is a
framed version.
T1 ESF – T1 stream with ESF framing. The PCM
signals are processed assuming that they are
encoded in accordance with the μ-law. You can
use this selection when the port Line Type is a
framed version.
T1 SF – T1 stream with SF (D4) framing. The
PCM signals are processed assuming that they
are encoded in accordance with the μ-law. You
can use this selection when the port Line Type
is a framed version.
UNFRAMED – unframed data stream,
transparently transferred. You can use this
selection when the port Line Type is UNFRAMED.
This is the only selection for SAToPSN
pseudowires, but it is not allowed for CESoPSN
pseudowires.
Default: E1
Sensitivity Used to select the optimum
parameters for the clock recovery
mechanism of the selected
pseudowire.
This parameter is not displayed for
HDLCoPSN pseudowires
DATA – Performance is optimized for accurate
clock recovery. This selection is optimal for data
transmission applications.
DELAY – Performance is optimized for constant
delay. This selection is optimal for voice
transmission applications.
Default: DATA
Voice OOS Selects the code transmitted during
out-of-service periods on the
timeslots defined as voice timeslots
(see the
Configuring Internal DS1
Port Timeslot Utilization
section).
This parameter is not displayed for
HDLCoPSN pseudowires, also when
the port uses the UNFRAMED mode
The available selections are 00 to FF (hexa).
Default: 00
