Specialist Task Force 314:
TETRA Release 2 Peripheral
Equipment Interface (PEI)
Who we are:
Team Leader: Indika Samarakoon
Team Members: Bahram Honary
Abdi Moinian
Jenny Bailey
Dave Healer
What we do :
At present the Work Item (WI)
for producing the TETRA Release 2 PEI standard has been produced and is waiting
for TC TETRA approval.
The STF will produce the
following deliverables for TB approval:
Scope: Enhancement of the existing PEI interface to add a high-speed data,
concurrent multimedia applications and QoS capability (see also sections 1.1.1
and 3.10).
- TS 300 392-2 (revised clause 30)*
Revised MEX layer
Scope: A
revision of the optional MEX layer in the TETRA Release 2 standard (clause 30)
to operate through the new PEI. This work is peripheral to the main task
in developing Release 2 PEI.
* The revisions in this clause will be added to the standard via a
Change Request (CR) nearer the time, for which a separate WI will be created.

Why we do it:
Since the year 2000 TC TETRA has dedicated its resources
primarily to the development of the TETRA Release 2 standard. This standard,
i.e. TS 300 392-2 V3.1.1 is due for publication in about a months time. The
all-important high-speed data technology part of this standard, being the TETRA
Enhanced Data Service (TEDS), has been developed to provide a wide-band
capability to handle IP based concurrent multimedia applications. The scope of
the TEDS enabled mobile station (on its own) to fully exploit this capability is
limited. Hence the use of a standard Peripheral Equipment Interface (PEI) to
facilitate access to this capability from a range of data terminals is even more
important than in the case of TETRA Release 1.
This is a time critical development since the TEDS standard (as integral part of
TETRA Release 2) is now available, and a number of manufacturers have embarked
on product development activities. The users of this technology will no doubt
require a PEI interface at the outset. Hence, the sooner this interface is
available the shorter is the time to market for TEDS products.
This interface needs to interact with an optional protocol layer (Multimedia
Exchange, or MEX, layer) already included in the TETRA Release 2 standard. This
layer provides switching and a precedence order for multiple applications
competing for TEDS resources. The MEX layer needs to be updated for a seamless
operation with a TEDS PEI interface. This work provides an ideal platform to
carry out both tasks to avoid any future interfacing problems.
Time plan for the work:
- Start of the work 15 September 2006
