2.5 Multiplexer Management
Selecting MULTIPLEXER MANAGEMENT from the main menu allows the
user to configure the multiplexer functions. If another user is currently
accessing the multiplexer management page (e.g. via a Telnet session) this
will be indicated next to the menu item. Only one session is allowed access to
the multiplexer functions at any one time. If NONE is displayed the user is
free to enter multiplexer management. If an IP address is displayed, then this
is the address of the user currently accessing the multiplexer functions. If
CONSOLE is displayed, then the multiplexer functions are being accessed
via the multiplexer supervisor port. You may choose to break their session if
absolutely necessary but this should be used with caution.

options that are available when the Router Option is fitted are detailed below.

2.5.1 Allocating bandwidth to the Router
The amount of bandwidth allocated to the router determines the throughput of
Ethernet data through the router. Bandwidth is allocated using the timeslot
map on the multiplexer Nx64 Channels page. Typing ‘R’ in the timeslot map
will assign that timeslot to the router. Any combination of timeslots may be
allocated to the router (except timeslot 0, which is always reserved) and each
timeslot assigned will contribute 64Kbps of bandwidth. The Rate field for the
router will automatically be updated to show the bandwidth assigned.
