Description Commands in this context configure the external BITS timing reference output from the node.
The user has the option to enable or disable the BITS interface output independently of each
other.

Platforms 7210 SAS-T (network and access-uplink), 7210 SAS-Mxp, 7210 SAS-R6 and
7210 SAS-R12
Description This command configures the BITS port to support one of the available interface types,
through T1/DS1 or E1 synchronization interface and the desired framing with that interface
type.
Note: On the 7210 SAS-T and 7210 SAS-Mxp, BITS2 inherits the values configured for
BITS1.
The no form of this command reverts to the default configuration.
Default ds1 esf
Parameters ds1 esf — Specifies Extended Super Frame (ESF). This is a framing type used on DS1

• The 7210 SAS-R6 and 7210 SAS-R12 only support the configuration of the BITS1
interface for use as an input or output reference.
• The 7210 SAS-T and 7210 SAS-Mxp support the configuration of both BITS1 and
BITS2 interface as an input and output reference.
• On the 7210 SAS-T and 7210 SAS-Mxp, the BITS1 configuration parameters such as
bits-interface-type, line-length, source-reference, and so on, are inherited for the
BITS2 interface. CLI commands are available to administratively control the BITS2
interface, allowing the user to shutdown or enable the BITS2 input and output
independently of the BITS1 interface.
circuits that consists of 24 192-bit frames, The 193rd bit provides timing and other
functions.
