tion is correct:

program or the Configuration Screen in the VT 100 menu system. The

correct and the unit is properly connected. If the link status is good
and calls still cannot be placed, review the section

Auto-Detect SPIDs/Switch

tect the SPIDs and the Switch Type.

• IRQ conflicts
• Wrong DTE speed
