Setting up aurora
Duet
- Section 1
Level 3
PBXX
Set call collision parameter to PBXX. PBXX always wins
during call collision.
PBXY Set call collision parameter to PBXY. PBXY always yields
during call collision.
Changing the Emulation - Examples
The following tables show the emulation settings you
would choose for testing ISDN protocol links and fixed
links.

Note
To test a cable or network without establishing a call,
refer to
Fixed links: Testing a Cable or Network without
Establishing a Call in Chapter 4 Section 2.
Emulation mode: ISDN Protocol Links
TE
,
Slave
Emulate a TE at Layers 1-3. Used for testing into the
network, including the NT.
NT ,
Master
On Primary Rate or the Basic Rate S interface, aurora
Duet
emulates an NT at Layers 1-3. Used for testing TEs and the
line itself.
LT ,
Master
(BRI)
Emulate a TE at Layers 1-3. Used on the U interface to test
the NT and the protocol between the LT and the TE via the
NT.
TE
,
Master
Emulate a TE at Layer 1 and an NT at Layers 2 & 3. That is,
aurora
Duet
acts as clock receiver at Layer 1 and the protocol
master at Layers 2 & 3.
NT ,
Slav e
On Primary Rate or the Basic Rate S interface, aurora
Duet
emulates an NT at Layer1 and a TE at Layers 2 & 3. That is,
it acts the network clock generator at Layer 1 and the
protocol slave at Layers 2 & 3.
LT ,
Slave
(BRI)
At the U interface, aurora
Duet
emulates an LT at Layer1 and a
TE at Layers 2 & 3. That is, it acts the clock generator at
Layer 1 and the protocol slave at Layers 2 & 3. May be used
for testing interworking between two PBXs.
