3 The CableCARD module reads the pairing information from the file. If the
CableCARD module finds its SSC pairing in the authorized list, it authorizes the
binding between it and the SSC host. If it finds its SSC pairing in the
unauthorized list, or if it does not find its SSC pairing in either list, it does not
authorize the binding.
You do not need to turn combo-binding "on." It is an automatic process available for
SSC DHCTs as long as you load the correct DHCT types, have the correct EMMs,
and have one of the following System Releases:
SR 2.5/3.5/4.0 Service Pack 3 (and later)
SR 2.7/3.7/4.2 Service Pack 0.2 (and later)

Autobinding is a process that allows the CableCARD module to bind to a two-way
host. The procedure is as follows.
1 When the CableCARD module is inserted into a two-way host, the host and the
1 When the CableCARD module is inserted into a two-way host, the host and the
CableCARD module exchange keys to authenticate each other.
2 After the keys are verified and the host goes into two-way mode, the
CableCARD module sends an upstream message to the DNCS that includes the
CableCARD ID and the Host ID.
3 The DNCS looks up the Host ID in the CRL. Based on the information in the
CRL, the DNCS takes one of the following actions:
If the host is in the list, the DNCS does not allow the CableCARD module to
bind to the host.
If the host is not in the list, the DNCS continues with the next step.
4 The DNCS looks up the CableCARD module/Host in its database to determine if
a Host Bound value has been defined for this pair. Based on this information, the
DNCS takes one of the following actions:
If the pair is in the list, and the Host Bound value is Yes, the DNCS allows
binding for this CableCARD/host pair.
If the pair is in the list, and the Host Bound value is No, the DNCS does not
allow binding for this CableCARD module/host pair.
If the CableCARD module is in the list with a different host, the DNCS
continues with step 5.
