Split Dial Shelves
Enter the dial-shelf split slots {slot-numbers} command, specifying the slot numbers that are to be
owned by the existing router shelf.
Step 5 Configure the new router shelf to operate in split mode on other feature boards.
Enter the dial-shelf split slots {slot-numbers} command, specifying the slot numbers that are to be
owned by the new router shelf. Do not specify any of the slot numbers that you specified in Step 4. The
range of valid slot numbers is 0 to 11.
Step 6 Install the second DSC, if it has not already been installed.
Step 7 Connect the dial-shelf interconnect cable from the second DSC to the new router shelf.
Step 8 Ensure that split mode is operating properly.
Enter the show dial-shelf command for each router. This command has been extended so that the
response indicates that the router shelf is running in split mode, and which slots the router shelf owns.
The status of any cards in any owned slots is shown, just as they are in the present show dial-shelf
command.
Step 9 Enable all feature boards to accept calls again.
Changing Slot Sets
You can change the sets of slots owned by the two router shelves while they are in split mode. First
remove slots from the set owned by one router, then add them to the slot set owned by the other router.
The changed slot-set information is sent to the respective DSCs, and the DSCs determine which slots
have been removed and which added. Moving a slot in this manner will disconnect all calls that were
going through the card in that slot.
To move a slot from one router shelf’s control to the others, first modify the router releasing the slot by
entering the dial-shelf split slots remove command specifying the slot numbers to be released. The
released slots can then be added to the slot set of the other router by entering the dial-shelf split slots
command including the new slot numbers.
When a slot is removed, the router shelf that is losing the slot frees any resources and clears any state
associated with the card in the slot it is relinquishing. The DSC reconfigures its hub to ignore traffic from
that slot, and if there is a card in the slot it will be reset. This ensures that the card frees up any TDM
resources it might be using, and allows it to restart under control of the router shelf that is subsequently
configured to own the slot.
When a slot is added, if there are no configuration conflicts, and there is a card present in the added slot,
a dial-shelf OIR insertion event is sent to the router shelf. The router shelf processes the event as a
normal event. The card in the added slot is reset by the DSC to ensure a clean state, and the card
downloads its image from the router shelf that now owns it. If the other router shelf (and the other DSC)
claim ownership of the same slot, the command adding the slot should be rejected. However, should a
configuration conflict exist, error messages are sent to both routers. The card is not reset until one of the
other router shelves and its DSC stop claiming ownership of the slot. Normally this will not happen until
you issue a dial-shelf split slots remove command surrendering the ownership claim on the slot by one
of the routers.
