Interface Connection

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 or T1 selection.
  • Signaling link: definition of the signaling channel (T1 or E1) for QSIG channel.
  • Data link: automatic B channel of BOP, BERT or BYTE-TS type.

Analysis Functions

Protocol Event Generation

• Physical level:  E1 and  T1 alarms.
• Signaling link:  QSIG channel HDLC frames.
• Data link: HDLC frames, BERT-G821 results or BYTE-TS blocks.
• DTMF 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, T1, I430,
• Signaling Link:
  • Data structure: BOP envelope.
  • Decoding according to a protocol stack with 7 decoding levels
  • QSIG layer with full ASN1 decoding
• Data Link:
  • Data structure: BOP envelope, BERT, BYTE-TS.
  • Decoding according to a protocol stack with 7 decoding levels

Simulation Functions

QSIG Automatic Simulation:

Behavior: Generator (1 to 32 outgoing SETUP’s) and/or responder (acceptance, 30 incoming SETUP’s).

• Independent outgoing communications defined by:
  • Delays and IE buffer for SETUP, INFOS, RELEASE.
  • Number of repetitions and inter-communications delay.
  • B channel establish and active source.
• Identical incoming communications defined by:
  • ACCEPT/REJECT behavior.
  • Transmission option and IE buffer for SETUPACK, CALL-PROC, RELEASE.
  • Delay before CONNECT.
  • Establish and active source of the B channel: default or indication by USER INFO.
• Manual commands: CALL, CLEAR, INFO, RESTART, etc..., DTMF values.
• Outgoing communications triggered by:
  • Starting delay.
  • Manual commands.
  • Incoming communications (for 15 outgoing communications).
• Call simulator data sources:
  • BOP Mode DL: X25 call simulator, user program.
  • DL Mode BERT: Pattern: 29 - 1 (V52), 211 - 1 (O152), 215 - 1 (O151), results according to CCITT G821.
  • DL Mode BYTE-TS.
  • LOOP.
  • External TRANSIT or TRANSDATA links.
  • COFIDEC 1 and 2 internal links on analog sources: DTMF 1 and 2,  HANDSET...

Emulation Functions

Physical Layer

• Emulation mode:  PNX-User or PNX-Network .

Link Layer: Q921

• SAPI 0 initialization
• Setting of Parameters (time-limits, numbering)

Network Layer: QSIG

• Selection of variants (ISO/ETSI) and side (A/B) ,
• Setting of Parameters (time-limits, numbering...)

Data Simulation

X25 Automatic Simulation:

• X25 automatic simulator can be run in:
  • D channel
  • B channel

Frame Relay Automatic Simulation:

• Frame Relay automatic simulator can be run in B channel

Programmable Simulation

API

• Use of CLARINET-Development C language
• Microsoft format library.
• Level N simulation using emulation on signalling channel.

Conformance Testing Simulation

ETS

• Use of ETS packages resulting from TTCN compilation:
  • QSIG Basic call
  • QSIG GFP
• 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.
