3.10.1 Modes of Operation
In the 1.x.0 system, the only mode available is XCON.
3.10.1.1 XCON Mode (XCON)
The XCON mode allows the user to cross-connect DS0s to user voice or data ports or to
cross-connect any DS0 on any WAN port to any DS0 on any other WAN port in the system.
The “Mode” setting on a WAN in a XCON system will only indicate the XCON option.
3.11 Assigning Time Slots
You must use a time slot map to specify the connections between all incoming and outgoing
lines connected to the system. The time slot map lets you split up your T1 bandwidth into
portions required for normal voice and data communications. It contains the connections for
all ports in your system.
3.11.1 Assigning a Time Slot to a User port Port
You can define a time slot map from any user port (data or voice) for connections involving
that port, or from a WAN port for cross-connections involving only WAN ports. For example,
Figure 3-15 shows the E&M port Main Screen for the time slot assignments. Assign time slots
to a voice port as follows:
1. From the System Main Screen, select the desired voice port and press <Enter>. That
port’s Main Screen appears.
2. Select the WAN port from which you want to assign time slots to the E&M port. In
Figure 3-15, this is W1-1 (for WAN 1, port 1).
3. Select a time slot (TS) for the first port. A number appears at the bottom of the screen
for the corresponding time slot on the WAN port.
4. Set the time slot number by using the up and down arrow keys to highlight it, then press
the <Enter> key.
5. Change the STATE of the port from stdby to actv.
6. Repeat steps 2 through 5 for the remaining port ports, to assign time slots to them.
7. Press “s” to save your settings, using the Save command in the port Main Screen.
