9-4 High Speed Data Ports
Model No.
Running Head
WA N
The WAN setting identifies the WAN port to which the output of this port is directed. I (the
options are w1-1 to w1-4).
MODE
The Mode parameter allows you to identify how the HSU port appears to the device on the
other end of the interface cable. The dce option causes the port to be recognized as a DCE
(data circuit-terminating equipment) device. The dce option is always chosen in the first
offering of the IMACS-200.This allows the end user to connect a dte device to the port.
TS
The TS (time slot) setting identifies the time slots on the WAN link when wan is the
WAN/SRV setting. The HSU ports can use many time slots on a single WAN port to create a
super-rate circuit for an individual HSU port. One or all DS0 time slots on a single T1 link can
be assembled for use by an HSU port in order to satisfy the speed requirements of the DTE.
The time slot numbers range from 1 to 24. Figure 9-2 shows the display when table is selected.
Using the space bar to select and deselect the time slot, this example shows time slots 10 to 12
on WAN 1-1 assigned to this port. The time slot assignments do not have to be contiguous on
any card port.
