High Speed Data Ports 9-7
CTS DELAY
The Clear To Send (CTS) Delay setting delays changes in the CTS signal in the local mode.
Enter the value you need in milliseconds. The available options are 0, 30, 60, and 100 ms. If
you do not know what value you need, start with 0 (zero) ms and increase the value gradually
until you no longer experience problems. The CTS option above must be set to locl before the
CTS DELAY setting has any effect.
LOCAL LB
The Local Loopback (LOCAL LB) option activates a loopback on the selected card port.
Choose the dte setting to loop the outgoing data from the external DTE device back to the
DTE receiver. This loopback (see Figure 9-3 on page 9-7) allows you to check the local
cabling and most of the circuitry in the HSU port. It also disconnects the incoming data from
the far end.
Figure 9-3.Local DTE Loopback
Choose the net (network) setting to loop the incoming data from the network back toward the
far end. This loopback is shown in Figure 9-4. It tests some of the local HSU Card circuitry,
the local system common cards, the WAN link card, the far-end HSU port and CPE device,
and the WAN link between the two sites. The net setting also drops the Data Set Ready (DSR)
control signal output on the HSU port.
