Function
Specifies the output level for the 4WTO
daughter card.
Note the following information about the
values:
0—Gain is 2:3 (signal is attenuated
33% or 1.8 dB).
25—Unity gain, which means there is
no attenuation or gain.
255—Gain is 4:1 (signal is amplified
400% or 6 dB).
Intermediate values are derived with
linear interpolation. The actual gain
depends on the impedance of the
attached device.
Enables or disables the active squelch
function on the circuit.
If enabled, specifies whether the squelch
is active or inactive.
The squelch function gates local audio
output when DSR-A (channel 1) or
RTS-A (channel 0) inputs are active or
inactive.
Enables or disables interoperability of
the 4WTO daughter card with
Multiservice Interface modules.
When you enable interoperability of the
4WTO daughter card with Multiservice
Interface modules, the port speed for the
bundle is set as follows:
64 when only channel 0 is enabled.
128 when dual channel is enabled.
Specifies the type of clocking for the port.
To prevent voice channels from
generating occasional noise bursts
caused by unsynchronized nodes, we
recommend that you configure one end
of the voice port (not both) for adaptive
clocking or lock both ends to clock
references.
Chapter 2: Configuring CTP Bundles
Your Action
Enter a number from 0 through 255.
Select one:
DISABLED—Disables the active
squelch function on the circuit
ENABLED/ACTIVE—Squelch input is
grounded and analog output is
disabled.
ENABLED/INACTIVE—No signal is
applied to the squelch input. Input is
open and analog output is possible.
Enabled—Interoperability with the
Multiservice Interface module is
enabled.
Disabled—Interoperability with the
Multiservice Interface module is
disabled.
Select one:
4WTO/IRIG - Master End—This end of
the circuit generates a clock signal and
sends it to the remote end.
4WTO/IRIG - Adaptive End—This end
of the circuit receives the clock signal
from the remote end. The clock slave
uses its period to determine when to
sample data and how to transmit data
across the link.
Custom—The custom clocking
configuration is used.
