IDSL Commands
An IDSL (ISDN Digital Subscriber Line) delivers a maximum symmetric 144 Kbps of bandwidth. The IDSL
bandwidth is composed of two 64 Kbps B channels, plus one 16 Kbps D channel. Your speed setting indicates the
channels that you are using.
When using Frame Relay:
¥ Your IDSL switch setting indicates your committed bandwidth (FR64, FR128, or FR144).
¥ The IDSL router can support several DLCI virtual circuits over a Frame-Relay IDSL link. However, a typical
connection to the Internet requires only one DLCI. The DLCI number must match the DLCI of the remote
end.
This section describes the following commands used to manage your IDSL router:
idsl list Lists the current Frame Relay switch type (FR64, FR128, or FR144).
idsl save Saves the IDSL changes.
idsl set switch Changes the Frame Relay switch type.
idsl set speed Changes the IDSL speed (64, 128, or 144).
remote setdlci Specifies the DLCI for the remote router entry.
remote setprotocol Selects the link protocol for the remote router entry (PPP, Frame Relay, or MER).
