Common Features in Release 8.0
This section provides information on new features that are common to all products in 
Release 8.0.
Configurable Transmit Timing Source
It is now possible to configure the transmit clock source, as either Building Integrated 
Timing Supply (BITS) or line-timing, for application services using SDH or SONET over 
the Optical line card or the Channelized line card. 
BITS-timing provides the transmit timing source, using Stratum 3 compliant BITS modules 
resident on either the SPIO with a BITS BNC interface or the SPIO with a BITS 3-pin 
interface. Line-timing recovers the receive timing from an external clock source via a port 
on an Optical or Channelized line card. It is possible to configure both clock sources, so that 
one timing source backs up the other.
To configure and manage this feature, a new CLI configuration sub-mode has been added to 
the Global configuration mode - the BITS Port Configuration Mode, details in the 
Command Line Interface Reference, includes the following new commands:
- default
- end
- exit
- mode
- preferred slot
- recover
- shutdown
- snmp trap link-status
Configuration of this clock source is explained in Configuring Transmit Timing Source in 
the System Administration Guide.
CDR PUSH Transfer Mode
The CDR files can be pushed from the chassis to the configured external storage server 
periodically using the SFTP protocol. This functionality is supported both on the ST16 and 
ST40 platforms.
With the PUSH transfer mode, the external storage server URL to which the CDR files need 
to be transferred should be specified. The configuration allows a primary and a secondary 
server to be configured. Configuring the secondary server is optional. Whenever a file 
transfer to the primary server fails for four consecutive times, the files will be transferred to 
the secondary server. The transfer will switch back to the original primary server when:
Four consecutive transfer failures to the secondary server occur
After switching from the primary server, 30 minutes elapses
With the push transfer mode, the following can be configured:
