SYNTAX Unsigned32 (0 | 5..65535)
UNITS "MHz"
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"This attribute specifies the starting (lowest) frequency for
which the downstream band is currently configured in the FDD
cable modem. This corresponds to the Advanced Diplexer
Downstream Lower Band Edge Configuration sent by the CM in
the Registration Request as TLV type 5.79. The two-byte
unsigned integer represents the frequency in MHz. The value
zero indicates the CM is currently not configured with a
channel in the extended spectrum."
