TE Green shows the unit is operating in PBX emulation
mode (DASS2) or PBXB mode (DPNSS).
NT Green shows the unit is operating in ET emulation
mode (DASS2) or PBXA mode (DPNSS).
The Layer 2 LED is not used for DASS or DPNSS.
Notes for CorNet-T Protocol Users
Layer 1 activation may take up to 35 seconds when
connecting to a CorNet-T switch. This is a feature of the
ISPBX which may vary according to load.
The result of attempting a data call from an aurora
Duet
which has been identified as a speech device (SET751 or
SET500) is indeterminate. The result of attempting a
speech call from an aurora
Duet
which has been identified as
a data device (DCI521 or DCI731) is also indeterminate.
Notes for QSIG Protocol Users
On all interfaces except 4B3T 'U', aurora
Duet
can act as
either Master (generator) or Slave (receiver) of the clock.
On a 4B3T 'U' interface, it can only act as the clock
Slave.
Because QSIG is an inter-network protocol, you do not
use aurora
Duet
to emulate a specific type of ISDN device
(TE, NT or LT). However, for consistency with other
protocols, these terms are used in the setup menus.
Therefore, to choose whether aurora
Duet
acts as clock
Master or Slave, you choose TE , NT or LT as if you were
selecting the device to be emulated. Thus:
Ø To configure aurora
Duet
as the clock Slave, choose TE
as the emulation mode.
Ø To configure aurora
Duet
as the clock Master, choose
NT or LT (2B1Q only) as the emulation mode.
