Confirming Headend Support
Network control of DSAN operation, like that of cable modems, is performed
remotely and automatically from the headend. For this process to work, the headend
equipment and software must be configured as described below.
remotely and automatically from the headend. For this process to work, the headend
equipment and software must be configured as described below.
DNCS
DNCS with SR4.3 must be installed at the headend.
CMTS Bridges must be set up for ADSG operation, as follows:
– CMTS Bridge (Advanced DSG) for SFM normal data flow
– CMTS Bridge (Advanced DSG with BT Headers) for SFM SI SCTE-65 data
– CMTS Bridge (Advanced DSG) for SFM normal data flow
– CMTS Bridge (Advanced DSG with BT Headers) for SFM SI SCTE-65 data
flow
– CMTS Bridge (Advanced DSG with BT Headers) for SFM EAS SCTE-18
data flow
Device types must be inserted into customer EMM files in DNCS and the
certificate loaded on DNCS.
certificate loaded on DNCS.
CMTS
CMTS with software that supports ADSG must be installed at the headend.
The CMTS must be set up for out of band (OOB) Bridge (Tunnel) operation,
as follows:
– For Traditional Data Tunnel, the client list must include the CA system ID
as follows:
– For Traditional Data Tunnel, the client list must include the CA system ID
(0xE00).
– For SCTE-65 (SI) Data Tunnel, no special configuration is required.
– For SCTE-18 (EAS) Data Tunnel, no special configuration is required.
– For SCTE-18 (EAS) Data Tunnel, no special configuration is required.
DHCP Server
The DHCP server must issue DHCP Offer and Ack to the embedded cable modem
(eCM) for each DSAN. The DHCP Offer and Ack contains the name and TFTP
location of the eCM configuration file.

location of the eCM configuration file.
The DHCP server must also issue DHCP Offer and Ack to the embedded host
(eHost) for each DSAN. The DHCP server must issue DHCP Offer and Ack with
mandatory options 1, 3, 6, 15, 51, 54, 66, and 67 enabled. The DSAN verifies the
existence of these fields within the DHCP Offer and Ack. If any of these DHCP fields
are absent, the DSAN must reject the offered lease and restart its DHCP IP
acquisition process.
