This attribute specifies whether the direct assignment of TCH
channel is enabled or disabled. The meaning of the setting values is
the following:

FALSE: Direct TCH assignment disabled;

SDCCHMS: Direct TCH assignment enabled but
disabled for “answer to paging-any
channel” cause of CHANNEL
REQUIRED message (since
SDCCHonly MS may be supported by
the network);

NOSDCCHMS Direct TCH assignment enabled also
for “answer to paging-any channel”
cause of CHANNEL REQUIRED
message (since SDCCHonly MS is not
supported by the network)
