Cisco IOS Dial Technologies Configuration Guide
The dial-shelf split slot 0 3 4 5 command must be defined for the dial-shelf split backplane-ds0 option
command to be active. You may also select the user defined option to define your own split.
Even if your system is already using a split dial shelf configuration, configuring one router shelf to
handle two T3 trunks and the other router to handle the third trunk requires you to take the entire access
server out of service. Busyout all connections before attempting to reconfigure. The configuration must
be changed to setup one pool of TDM resources that can be used by either DMM cards or UPCs, and a
second pool of two streams that contains TDM resources that can only be used by UPCs.
You may have more trunk capacity than 2048 calls. It is your decision how to provision the trunks so the
backplane capacity is not exceeded. If more calls come in than backplane DS0 capacity for that half of
the split, the call will be rejected and an error message printed for each call. This cannot be detected
while a new configuration is being built because the router cannot tell which T1 trunks are provisioned
and which are not. The user may want some trunks in hot standby.
The DMM, HMM, and VoIP cards can only use 1792 DS0 of the available 2048 backplane DS0. The
UPC and trunk cards can use the full 2048 backplane DS0. The show tdm splitbackplane command will
show the resources in two groups, the first 1792 accessible to all cards, and the remaining 256 accessible
only to UPC and trunk cards.
For more information about split dial shelf configuration, refer to the Cisco AS5800 Universal Access
Server Split Dial Shelf Installation and Configuration Guide and the hardware installation guides that
accompanied your Cisco AS5800 Universal Access Server.
Configuring SPEs to Use an Upgraded Firmware File
To configure the SPEs to use the upgraded firmware file, use the following commands beginning in
privileged EXEC mode to display the firmware version number:
Command Purpose
Step 1
Router# show spe version
Displays SPE firmware versions to obtain the On-Flash
firmware filename.
Step 2
Router# configure terminal
Enters global configuration mode.
Step 3
AS5400:
Router(config)# spe slot/spe
or
Router(config)# spe slot/spe slot/spe
AS5800:
Router(config)# spe shelf/slot/spe
or
Router(config)# spe shelf/slot/spe
shelf/slot/spe
Enters the SPE configuration mode. You can choose to
configure a range of SPEs by specifying the first and last
SPE in the range.
Step 4
Router(config-spe)# firmware upgrade {busyout |
download-maintenance | reboot}
Specifies the upgrade method.
Three methods of upgrade are available. The busyout
keyword waits until all calls are terminated on an SPE
before upgrading the SPE to the designated firmware. The
download-maintenance keyword upgrades the firmware
during the download maintenance time. The reboot
keyword requests the access server to upgrade firmware at
the next reboot.
