Clarinet Trunk application
Presentation
The Clarinet-system is a powerful Protocol Test
platform supporting E1/T1 interfaces and protocols. It offers a wide
variety of functions:
- Monitoring
- Automatic simulation
- Conformance testing for data protocols (X25, Frame
Relay)

Clarinet-system: basic configuration
Physical interface
- E1 75 or 120 Ohms
- T1 75 or 100 Ohms
Interface management
- Simultaneous management on each interface
of three types of PH, SL, DL links:
- PH-Physical Interface: E1 T1 selection.
- Signaling Link: definition of a 64kb/s BOP channel.
- Data link: Definition of a Nx64 kbits/s (from 1
to 31 aggregated TS) allowing transfer rate up to
1984 kbits/s with BOP, BERT data structure.
Protocol event generation
- Physical Level: G703 and T1 alarms, CAS (abcdbits) .
- Signaling Link: HDLC
frames, SS7-MTP2 messages.
- Data Link: HDLC frames, BERT-G821 results
or BYTE-TS blocks.
- DTMF tone code.
Statistics event generation
- BOP type event counters on SL or DL.
- Data-flow counters on BOP link at
different protocol layers.
Protocol specification for display
- Physical Link: E1 TS0, CAS abcd bits.
- Signaling Link:
- Data structure: BOP envelope, SS7.
- Decoding according to a protocol stack with 7 decoding
levels
- Data Link (protocol stack with 7 decoding
levels):
- Envelope BOP, .
- Data structure: BOP envelope, SS7, BERT,
BYTE-TS.
- Decoding according to a protocol stack with 7 decoding
levels
Simulation
function
- On Data Link:
- BOP mode:
- X25 automatic simulator,
- Frame Relay automatic simulator
- BERT Mode :
- Pattern: 29 - 1
(V52), 211 - 1 (O152), 215 - 1
(O151),
- Results according to
CCITT G821.
- BYTE-TS mode:
- On any TS:
- LOOP.
- TRANSIT or TRANSDATA
links.
- COFIDEC 1 and 2 internal links on
analog sources: DTMF 1 and 2, HANDSET...
Physical Layer
- Emulation mode: Network or User.
X25 Automatic Simulation:
- X25 automatic simulator can be run
in:
Frame Relay Automatic Simulation:
- Frame Relay automatic simulator
can be run in B channel
API
- Use of CLARINET-Development C language
- Microsoft format library.
- Level N simulation using emulation on signaling channel.
ETS
- Use of ETS packages resulting from TTCN compilation:
- X25 ISO ETS
- FR SVC and PVC
- Template of profiles, PICS/PIXIT
- Execution under Clarinet Run-time
ATS
- The Clarinet TTCN compiler and the stack of emulators allow the users to develop
or customize new ETS.
