Data Link Connection Identifier (DLCI)
The IDSL router can support several DLCI virtual circuits over a Frame-Relay IDSL link. However, a
typical connection to the Internet will require only one DLCI. The DLCI number must match the DLCI
of the remote end. An activated router should show all green lights for LINE, CH1, CH2, and NT1 LEDs.
The following IDSL commands are used to manage the IDSL link for an IDSL router.
