Nortel Remote Gateway 9110 Release Note page 18

Standard 1.0
The ISDN link between the RLC and Remote Gateway 9100 Series
units is always up because of lamp audit (Q01058550)
When the RLC was connected through the PSTN to the Remote Gateway 9100
Series units and the lamp audit would run with no active calls, the data port of
the RLC would dial the ISDN line of the Remote Gateway 9100 Series units. A
new X11 message was added for M39xx series digital telephone sets that would
send an Icon Status message to the M39xx series digital telephone set during
Lamp Audit. This was a new message that the Remote Gateway 9100 Series
product did not recognize and was therefore passing it to the Remote Gateway
9100 Series units each time it was received. In an on-demand connection
environment, this was causing the signaling link to be established each
successive time. The Remote Gateway 9100 Series firmware is now aware of
this new message type and prevents redundant transmission of this message
during a lamp audit.
During a transfer on a Remote Gateway 9150 unit, a local call is
inbound (Q01080804)
When a second inbound local ISDN call was received, while the telephone user
was in the middle of transferring an already received local ISDN call, the second
inbound call was dismissed from the digital telephone set once the telephone
user completed the transfer of the initial inbound call. The Remote Gateway
9150 units firmware now includes logic to handle the second inbound call
correctly when a transfer is progressing on the first inbound call.
In CS 2100 PBX environments, the Remote Gateway 9150 unit
produces a one-way voice path (Q01098111)
In CS 2100 PBX environments, the Remote Gateway 9150 unit was producing a
one-way voice path after picking up a call that was on hold. The Remote
Gateway 9150 firmware is now aware of Key Map Download (KMDs)
messages on their way to the digital telephone set and establishes the switch type
accordingly to the CS 2100 PBX. The Remote Gateway 9150 unit no longer
produces a one-way voice path.
