Port Number—Enter the port number on the DNCS that the CableCARD
server will monitor for incoming CableCARD module requests. The port
number is 13830.
Note: If you do not want to use autobinding for CableCARD modules, enter
Note: If you do not want to use autobinding for CableCARD modules, enter
0 in this field.
Authorization Time-out Period—Enter the length of time (in hours) the
Host-CableCARD pair is kept in the file on the BFS. We recommend that you
enter 2 in this field.
Notes:

Notes:
–
Negative values are not permitted in this field.
–
If you define a value greater than 2, be aware of the following issues:
The podData file on the BFS can contain no more than 1500 entries.
During staging, a pod (CableCARD)/host pair is added to the
podData file for the amount of time defined in this field. When the
Authorization Time-out Period is reached, the pod/host pair is
removed from the file.
If you attempt to exceed 1500 entries during the time-out period that
you have defined, pod/host pairs will not be able to bind.
Deauthorization Time-Out Period—Enter the length of time (in days) the
Authorization message is kept in the file on the BFS. Enter 30 in this field.
Max Key Session Period—Enter the rate that the copy protection key should
change. The rate referenced depends on the communications mode of the
CableCARD module, as determined by the host's capabilities:
–
–
Multistream Mode (MMode): The field represents minutes. Therefore,
entering a 1 in this field causes the copy protection key to change every
minute. Enter 1 in this field.
–
Singlestream Mode (SMode): The field represents decaseconds.
Therefore, entering a 1 in this field causes the copy protection key to
change every 10 seconds. Enter 10 in this field.
Important: Defining a rate less than 1 minute (for MMode) or 10 decaseconds
(for SMode) requires a large number of unnecessary calculations on the
CableCARD. Defining a rate greater than X minutes (for MMode) or 20
decaseconds (for SMode) does not coincide with best security practices.
Maximum Host Change Count Allowed (SR 4.2.1 only)—Enter the
maximum number of times that a CableCARD module is allowed to
autobind with a different host. When a module exceeds this limit, it is no
longer allowed to autobind with a different host.
Note: The default setting of 99 allows an unlimited number of autobindings.
