Start Channel
Selects the starting channel in the 31-channel DS1 bit stream. Starting with
the specified channel, the unit automatically assigns the channels that follow.
# of Channels
Specifies the number of channels to be assigned to the DTE.
Channel Rate
The unit can operate at any data rate that is a multiple of 56 or 64 kbps. If
“
Ν
x64K” is selected, the ones density requirements of the E1 network line
must be ensured. If “
Ν
x56K” 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.”
Invert Clock
(Applies to Serial 2
Screen Only)
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. Consequently, this configuration option should
remain disabled when configuring services for the Serial 1 port.
Values: Disable, Enable
Default: Disable
Tx Clock
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.
LL
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
