perceive it by distortion measurements. RBS signaling support should not be used on channels
carrying information other than voice audio as it corrupts the data in the channel.

CAS

E1 systems use CAS to carry voice call information. Instead of embedding this information in the same
channel as the voice audio, channel 16 of the E1 is reserved for all of the remaining channels to use
for signaling.

2.11 Software Download

During normal operation, the CM-30 module loads the primary image. Should it fail to boot the
primary image, the module then attempts to load the secondary image.
In the case of a failure in loading both the primary and secondary image, you can configure the CM-30
module to load an image from a remote FTP server. This image is not saved to either of the flash
memory devices. You can also configure the module to load the secondary image first, but if that fails,
the module moves directly to loading from the remote FTP server and does not try to load the primary
image.
When shipped from the factory, the CM-30 IP interface module contains the most recent version of the
system software. As new features and improvements become available, the CM-30 module software
should be updated to the most current revision.
The CM-30 software can be upgraded by opening an FTP session with the module and transferring a
new image file to the flash memory device. You can configure both the primary and secondary images
to be loaded from the same file or from two different file images. In addition, you can store multiple
software images on the CM-30 module 1 up to the limit of the flash memory. To obtain the software

2.12 Configuration Files Backup and Restoration

The CM-30 module has the ability to back up and restore configuration files at any time using either
the Web browser interface or SNMP software. CM-30 module configuration is stored in multiple files on
the flash memory (/RFA/cfg). Backup/restoration ability is critical to replacing CM-30 modules. It also
facilitates in the replication of NetXpress LX systems across a network.
Once a CM-30 module is removed from a NetXpress LX shelf, the persistent configuration information
for the system remains with the CM-30 module and is not available to a new module inserted in the
system. This same information can be restored quickly from an FTP server (via Internet) to the flash
memory on the new CM-30 module. The information can also be backed up easily to the server using
the same process, only in reverse order. Restored configuration takes effect when the CM-30 module
is rebooted.
