ISDN Digital Subscriber Line (IDSL)
General information about IDSL
DLCI (Data Link Connection Identifier)
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 have the LINE, CH1, CH2, and NT1 LEDs all lit green.
The following IDSL commands are used to manage the IDSL link for an IDSL router.
