PCM Encoding
The TSP configuration software defaults to mu-law PCM Encoding which is the North American
standard for T1. PCM encoding refers to the process used to digitize the analog signal. It is
necessary to ensure this matches the equipment under test. E1 normally uses a-law PCM
encoding.
Important
On Dual T1/E1, both channels are configured for the same clock, framing (for T1), signaling (for
E1), and line coding. Ensure the T1/E1 parameters are consistent with the configuration of the
equipment under test. This information can be found in the equipment manual or by contacting
the vendor.
PRI Tab
The
Global PRI Parameters
are configured on this tab. This includes programming the PRI switch
platform and the end the TSP will simulate.

Switch Type
The
Switch Type
is chosen by clicking the arrow and choosing the appropriate parameter. The
options available are
AT&T 4ESS
,
AT&T 5ESS
,
NT DMS-100/250
, and
US National ISDN
. These
options cover the majority of the North American switch types.
Simulation
The
Simulation
establishes the end the TSP will be communicating with.
Network
is chosen when
the TSP simulates the central office.
CPE
is chosen when the TSP simulates the Customer
Premise Equipment.
