Dial-up connection problems.

A variety of causes may result in dial-up connection problems.

Status Buffer messages returned from the ISDN network and the
Express 3000 SP can help diagnose many dial-up connection
problems.

Access these messages by clicking

Status Buffer

(Local or

Remote) on the

diagnostics

option on the ADTRAN

Express Configuration window.

b. Alternatively, you can access the

Status Buffer

by using the

key sequence

Ctrl+V

in the VT-100 menu system. (To invoke

the VT-100 menu system, issue the AT command

AT!V

from

a terminal emulation package such as HyperTerminal.)

Ensure the following to verify the correct protocol is selected:

•

PPP or V.120 generally for Internet applications

•

V.120 or Multilink PPP for work-at-home
