Description (
settings in boldface type are default settings)
Interface Type
Select the interface standard for Nx64k serial data port. The
options are: V.35,
V.36
, X.21, and RS-530.
Data Rate/# of TSs
Specify the Nx64k transmit data rate as the number of kbps or the
number of Nx64k time slots.
64 to
1536
(kbps)
Enter the data rate from 64 to 1536 kbps (for example, 64, 256,
768). Factory default setting is 1536 kbps (24 time slots).
0 to
24
(time
slots) Enter the number of Nx64k time slots up to 24 (for example, 1,12,
24). Factory default setting is 24 (1536 kbps).
Beginning TS
Enter the number of the beginning time slot for the transmitted
serial data. Options are time slots 1 to 24 in STRUCT application
mode and time slot 1 in UNSTRUCT mode. The factory default
setting is time slot
1
.
Transmit Clock
Specify the transmit data (SD) clock as External (EXT)
,
Internal
Rising Edge (
INT_RISING
), or Internal Falling Edge
(INT_FALLING).
CTS/DSR/RLSD
Specify one of three methods the LTU and NTU uses to generate
the CTS, DSR, and RLSD control signals for the Nx64k serial data
port. The Nx64k port is hardware configured as DCE. Set each of
these parameters to match the requirements of the application. The
choices are:
STD
(standard)
The output control signal follows the ITU standards.
ON (force ON)
Control signal is always ON.
OFF (force OFF)
Control signal is always OFF.
LL/RL
Select whether the LTU and NTU responds to or ignores the Local
Loopback (LL) and Remote Loopback (RL) control signals.
DIS
The LTU and NTU ignores LL and RL control signals.
ENA
The LTU and NTU responds to LL and RL control signals. Status of
local and remote loopbacks appears on the Test display.
