New in this Release

The following firmware versions incorporate a number of additional features
and enhancements.

1.6.11/2.6.11 Release

Dynamic Entry Channel Mode

Dynamic ECM (ECMv2) utilizes a modified slotted Aloha method for Remotes
to establish registration in the network and obtain the means for switching into
SCPC mode. Rather than sharing an STDMA burst map, as is the method with
STDMA ECM, the Remotes rely on communicating with the Hub channel
controller through the use of a multicast Transmission Announcement Protocol
(TAP) message. This eliminates the restriction in the number of Remotes in an
Entry Channel group that is inherent with the burst map method.
