The timeout period is a Þxed, non-conÞgurable parameter of 5 minutes. If
the remote 3088RC (far-end) has received no command within 5 min-
utes, it automatically terminates the RCS. Once the RCS is terminated,
the PC (far-end) can establish a local console session if desired. How-
ever 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 3088RC
(far-end) waits indeÞnitely for input (which is the system upgrade
image) from the local console port of the 3088RC (far-end). If this
command is entered, 3088RC (Far End) will have to be power-cycled.
