End-to-End Control Sets
There are four types of End-to-End Control Sets. They are set up using
Dialed, Switch Emulation
,
Channel Bank
, and
DS0 to DS0
Control Set Types. With this operation the TSP passes traffic
through from one channel to another.
Dialed Control Set Type
-The
Dialed
Control Set Type allows for calling from one channel to
another by dialing a telephone number. A telephone number is assigned to each of the channels
being tested on the
Slot
tabs at the
Units
Screen. The
Phone Number
field in the
Channel
Configuration
portion of the screen is used to assign the number to a channel.
A channel is called when the
Phone Number
is dialed from another channel assigned to the same
Dialed Control Set. The
Control Set
screen gives the option to use up to two different Templates.
An Analog POTS channel and a T1/E1 channel can be in the same control set. Or, you can also
use two different T1/E1 channel types.
Note:
When creating a template for a Dialed Control Set, ensure
Dialed
is chosen as the
Default Timing
Set
on the
Template
screen. See Figure 22. This will ensure proper operation when making a
call.
Switch Emulation Control Set Type
- The
Switch Emulation
Control Set Type will allow the a
connection between any Channel Protocol and any other except for T1/E1 Clear Channel. In this
mode, the TSP simulates a switch connection and will pass voice traffic. It simulates the
connection of a call by automatically connecting the channels assigned once an off-hook is
initiated by either end.
Note:
Calls are static and are not routed by telephone number, but by channel assignment in the
Control Set. See Channel Assignments section for more details. Also, call progress including dial
tone and ringback is done by a scripted timing rather than action done by dialing a number.
Channel Bank Control Set Type
- For
Channel Bank
operation, an
Analog Loop Start
channel can
be connected to a
T1/E1 FXO Loop Start
channel or a
T1/E1 Clear Channel
.
Channel Bank Simulation
- For T1/E1 FXO Loop Start to the Analog Loop Start, the POTS
channel connects with the T1/E1 FXO Loop Start channel and will pass voice traffic. This
simulates a channel bank.
The T1/E1 Clear Channel to Analog Loop Start setup will allow a channel bank setup between a
POTS port and a T1/E1 clear channel. This allows the TSP to connect to a T1 port on an SS7
system to provide voice traffic. An external control is required to provide for SS7 signaling on the
equipment under test when establishing a call.
In this configuration, when the POTS phone goes off-hook, the audio path will be connected to
the T1 channel. When the POTS phone goes on-hook the T1 channel will receive silence. Since
the T1 channel is clear channel there will be no signaling between the two channels.
Note:
Ringing to the POTS port is not available due to the absence of signaling in T1 Clear Channel
operation.
DS0 to DS0 Control Set Type
- The
DS0 to DS0
Control Set will only allow the use of a template
created for
T1/E1 Clear Channel
protocol. This can be done on a Single T1/E1 by connecting a
channel to another channel on the same T1/E1 or on the Dual T1/E1 module, connecting a
channel from the Port 1 T1/E1 to a channel on the Port 2.
Note:
Fractional T1 and T1 data is not supported. Data is only supported at the DS0 64K channel level
to another 64K channel.
Template Field
Clicking on the down arrow of the
Template
field gives the choices of the Templates that have
been created which can be used for the Control Set Type chosen. The program determines this
by the Channel Protocol assigned to the Template. A new template can also be created from this
Telecom Simulation Platform
