Here are all the parameters associated with all interfaces except with the F8011-96.
Baud Rate
:
•
Interface V35 and V11/X21 from 64 kbits/s to 2048 kbps by step of 64k and 4096, 6144, 8192 kbps.
•
Interface V28 synchronous:1.2KBPS; 2.4K; 4.8K; 9.6K; 19.2K; 38.4K; 48K; 56K; 64K; 128KBPS.
•
Interface V28 Asynchronous (transparent up to 115,2 kbps ).
Fractionnal E1
:
•
Disable: chose the speed only
•
Enable: with a remote framed fibre optic modem like an E1 modem, this parameter allows to choose the Time slot of the remote unit.
•
C37.94: with this mode, and only at 64 kbps, the transport in the fibre optic used is the IEEE C37.94 protocol.
Clock source
:
•
Internal clock: the transmission to the network is synchronized by the internal clock (based on a crystal oscillator in interface X21,
V35, V28 synchronous.
•
External clock: clock is provided by the DTE and is sent to the remote unit. Apply on X21, V35, synchronous V28.
•
Network clock: the transmission to the network is synchronized by the clock recovered from the network receive path. (Default value).
In interface X21, V35, V28.
Inverted clock
:
•
Data are generated on the falling edge of the clock for the X21, V35 and V28 interfaces (default behaviour). However it’s possible to
select the rising edge of the clock.
RDL
:
•
Remote Digital Loop. This command enables or disables answer to RDL requested by the remote FO serial. Disable by default.
DSR Control:
•
This parameter controls the activation of the DSR - 107 signal of the V35 or V28 interface. (forced: always active, follows the 108 /
DTR signal of the interface, active when the FO Serial is synchronized on the fibre optic ).
CTS control
:
•
This parameter controls the activation of the CTS - 106 signal of the V35 or V28 interface. (forced: always active, follows the 105 /
RTS signal of the interface, active when the FO Serial is synchronized on the fibre optic ).
CD control
:
•
This parameter controls the activation of the CD - 109 signal of the V35 or V28 interface. (forced: always active, active when the
FO8000 is synchronized on the fibre optic ).
I control
:
•
This parameter controls the activation of the I - 106 signal of the X21 interface. (forced: always active, follows the C signal of the
interface, active when the FO8000 is synchronized on the fibre optic ).
5.3.3. Menu 2 : Status and statistics
The FO Serial displays its operating parameters and connection statistics for evaluation of the transmission quality. See chapter 6 for more
information.
