SYNTAX Unsigned32 (0 | 5..65535)
UNITS "MHz"
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"This attribute specifies the ending (highest) frequency for which
the downstream band is currently configured in the FDD cable modem.
This corresponds to the Advanced Diplexer Downstream Upper Band
Edge Configuration sent by the CM in the Registration Request as
TLV type 5.80. 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."
