Table 2-4. External Port Parameters
Parameter Description
Connect Determines whether the port will be connected to the main link
YES Port is connected. This selection is effective only when the module itself is
connected to the main link
NO Port is disconnected. You can still program the desired parameters, so the channel
will be ready to operate when needed
Rate (kbps) Specifies the port user's data rate, 2.4, 4.8, 9.6 and 19.2 kbps.
For bandwidth limitations, refer to Section 1.2.
Clock Mode Specifies the clock mode you want to use for this port:
DCE DCE timing mode
External DCE External DCE mode, suitable for tail-end circuits.
DTE DTE timing
CTS Specifies the delay between the activation of the RTS line of a local port and the
activation of the corresponding local CTS line:
ON The CTS line is constantly ON.
RTS min Minimum delay (maximum 20 msec)
RTS max Delay of 50 msec (nominal value)
To maximize throughput, whenever possible use the ON selection.
DCD Specifies the function of the DCD line:
ON The DCD line is constantly ON.
CARD SYNC The DCD line is ON only when the module is synchronized
Start Envelope When the MANUAL envelope assignment mode is used, is used to select the starting
envelope for this channel. For guidelines, refer to Section 1.2.
When the AUTOMATIC envelope assignment mode is used, displays N/A
Time Slot
Assignment
After completing the configuration of the module, and when applicable, the
configuration of the other modules included in the same group, it is necessary to
assign a main link time slot to the module group.
The time slot assignment is made by entering the number of the slot in which
the module is designated as member number 1 in a group of LS-2 modules.
Perform manual time slot assignment, as explained in Chapter 3 of the
MEGAPLEX-2100 Installation and Operation Manual.
