Configuring the Main Link Parameters
For a list of the main link parameters, refer to the
Configuration Parameters
appendix. Remember that even if downloading is enabled, you must locally
configure the main link SPEED and TIMING on both the local and remote
MX-2100 units.
•
SPEED
- Select the main link data rate specified for your MX-2100: 9.6, 14.4,
19.2, 28.8, 32, 48, 56, 64, 128, 192, 256, 384, 512, 768, 1024, or
1536 kbps.
If you are reducing the main link data rate, the following error conditions may occur
while the main link rate is reconfigured:
The total data rate of the currently-active channels may exceed the new rate. This
will result in CONFIG ERROR 07 (bandwidth overflow).
With a main link data rate of 256 kbps, it is not possible to select a KHS.1 channel
rate of 192 kbps. This will result in CONFIG ERROR 9.
With a main link data rate of 768 kbps, it is not possible to configure a KVC.1
module (this module is not supported at this main link rate). This will result in
CONFIG ERROR 9.
To correct the problem, change the channel parameters as required.
•
TIMING
- Select the timing mode specified for your MX-2100:
−
When the installed module is KML.1, KML.2, KML.3 or KML.4, the
available selections are DTE, DCE or E-DCE. With DCE and E-DCE, a
reference timing source must be selected as explained for the system
parameters.
−
When the installed module is KML.5 or KML.6, the available selections are
INT and LBT.
−
When the installed module is KML.7, KML.8 or KML.F, the available
selections are DCE, INT and LBT.
•
When the timing reference is the internal oscillator (irrespective of the installed
main link module), it is not recommended to select clock mode DTE2 for data
channels.
•
BUFFER_SIZE
- If the selected interface type is DTE or E-DCE, select the
appropriate buffer size, in accordance with the communication link media:
±
256 bits for satellite links and
±
8 bits for any other medium.
•
DSR&CTS
- If the installed interface module is KML.1, KML.2, or KML.3, select
the desired method of handling the DSR and CTS lines: INT if you want these
lines to be ignored, or EXT if you want the transmit data to be held at MARK
when either of these lines is OFF.
Configuring the Channel Parameters

their channels and for specific configuration instructions, refer to the
