The timeout period is a fixed, non-configurable parameter of 5 minutes. If the remote 3088 (far-end) has received no command within 5 minutes, it automatically terminates the RCS. Once the RCS is terminated, the PC (far-end) can establish a local console session if desired. However if the PC (near-end) wishes to re-establish a RCS, it is able to do so whether or not the PC (far-end) is in an active local session, because the RCS has priority over a local console session. If the PC (near-end) establishes an RCS while the PC (far-end) is on a local session, the PC (far-end) is kicked off.

Differences in Local and Remote Control Session Behavior

Since the remote console session communication occurs over the G.SHDSL link’s EOC channel, some commands via the RCS have unusual effects.

•system upgrade: Do not issue this command via an RCS. A system upgrade must be done via the local console connection. If you should accidentally issue this command over an RCS, the remote 3088 (far- end) waits indefinitely for input (which is the system upgrade image) from the local console port of the 3088 (far-end). You must power- cycle the remote 3088 (far-end) to return it to the normal operational state. If this command is entered, 3088 (Far End) will have to be power-cycled.

•dsl set loopback lal: When this command is issued over the RCS, clearly the PC (near-end) can no longer communicate with the remote 3088 (far-end). See the diagram. Consequently the remote 3088 (far- end) can no longer receive any commands over the DSL channel from the PC (near-end). To recover from this situation, the DSL link will have to be dropped prior to establishing the RCS again. A short expla- nation is in order. Since the remote 3088 (far-end) no longer receives any commands from the PC (near-end), the RCS will time out in 5 min- utes and attempts to send a disconnect message back to the local
