WAN

The WAN setting identifies the WAN or OWAN directed. I (the options are wan-1to wan-4,and

port to which the output of this port is owan-1to owan-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 or owan is the WAN/SRV setting. The HSU ports can use many time slots on a single WAN or OWAN port to create a super-rate circuit for an individual HSU port. One or all DS0 time slots on a single T1 or E1 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 for T1, and 1 to 31 for E1. Figure 9-2shows 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.
