The unit can operate at any data rate that is a multiple of 56 or 64 kbps. If
"Νx64K" is selected, the ones density requirements of the E1 network line
must be ensured. If "Νx56K" is selected, ones density for the selected DS0
channel is maintained.
Values: Nx56K, Nx64K
Default: Nx64K
NOTICE:
Start Channel, Number of Channels, and Channel Rate cannot be
changed if Bundling is not also changed from "Arbitrary."
In DTE Packet mode, this parameter changes the clock edge of the
transmitted data. The Invert Clock parameter is only available for use in DTE
mode on the Serial 2 port.
Values: Disable, Enable
Default: Disable
Selects the number of bits required to make up one asynchronous character.
Values: Five, Six, Seven, Eight
Default: Eight
Selects the clock the unit uses to sample the data transmitted from the DTE.
When set to "Internal," the data is sampled directly with the transmit data
clock that is also supplied to the DTE as Transmit Clock. The "External"
option uses the external clock from the DTE.
Values: Internal, External
Default: Internal
NOTICE:
The "External" option is valid only in Packet mode.
Selects the port's operating mode.
Values: Sync, Async
Default: Sync
Sets the parity bit if the port is asynchronous.
Values: None, Odd, Even
Default: None
Selects the number of bits required to end the character.
Values: 1, 2
Default: 1
The Local Loopback (LL) parameter can be set to "Enable" or "Disable."
Selecting "Enable" allows the unit to go into Local Loop when the LL pin on
the Serial port goes high. The unit exits the loop when the LL pin goes low. If
you select "Disable," the unit ignores the LL pin on the Serial port.
Values: Disable, Enable
Default: Disable
