Interface Connection

Physical Interface

• One to Seven E1 Links (75 or 120 Ohms)

Interface Management

Simultaneous management of groups of E1 interfaces:

• PH-physical interface
• C-channels on Links 1 to 7 (2 per Link: TS16+15)
• Bearer channels on Link 1 to 7 (source: all Loops +1 handset).

Analysis Functions

Protocol Event Generation

• Physical level: E1 alarms.
• C channels: HDLC frames.

Statistics Event Generation

• BOP type event counters on C Channels.
• Data-flow counters on BOP link at different protocol layers.

Protocol Specification for Display

• Physical Link: E1 ITU recommendations  G703, G704.
• C channels:
  • BOP envelope , 
  • V5 protocol stack: V5 EF, V5 Data Link, V5 Network
  • ISDN Q921, Q931

Simulation Functions

V5 Automatic Simulation

• Interface specification
  • 1 to 7 E1 Links
  • 1 ISDN port (BRI or PRI) and 100 PSTN ports simulation
  • Protection, Control, Link Control, BCC, PSTN, ISDN
• Automatic simulation over 100 PSTN ports and 1 ISDN port
• Manual commands: send primitives applying to each ISDN/PSTN port, E1 Link (blocking, unblocking)

PSTN Automatic Simulation:

Behavior of each of the 100 ports: generator and/or responder.

• Outgoing and incoming communications defined by a common specification:
  • IE buffer for SIGNAL, ESTABLISH, DISCONNECT messages.
  • Conditions on incoming events
  • Delays
• Independent outgoing communications defined by:
  • Delays and digits for SIGNAL messages.
  • Number of repetitions and inter-communications delay.
  • Automatic digits sending
  • Manual commands: CALL, CLEAR, CLEAR ALL

Q931 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 response messages
  • Delay before CONNECT.
  • Establish and active source of the B channel:
• Manual commands: CALL, CLEAR, INFO, RESTART, 

Emulation Functions

Physical Layer

• Emulation mode: AN or LE
• Protocol mode: V5.1 and V5.2,

V5 Link Layer

• Setting of Parameters (time-limits, numbering)

V5 Network Layer: 

• Selection of  ETSI specification (Ed1/ Ed2)
• Start-up procedure configuration and V5.1 channels allocation
• Setting of Parameters (time-limits, numbering...)

PSTN Network Layer

• PSTN port provisioning, addressing

ISDN Link Layer: Q921

• SAPI 0,16 and 63 initialization
• Setting of Parameters (time-limits, numbering)

ISDN Network Layer: Q931

• Selection of national variants (ETSI, NI2,ATT...)
• Setting of Parameters (time-limits, numbering...)

Programmable Simulation

API

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

Conformance Testing Simulation

ETS

• The V5.1&V5.2 pr(I)ETS define V5-serie signaling protocol for:
  • LE equipment applying to Link Layer or Network Layer.
  • AN equipment applying to Link Layer or Network Layer.
• These ETS products include the Executable Test Suites corresponding to a set of ETSI standards covering the V5-serie protocol specification.  ETS packages result from compilation with Clarinet TTCN compiler.
  • V5.1 protocol specifications ETS 300 324-1 (Edition 1 and 2)
  • V5.2 protocol specifications ETS 300 347-1 (Edition 1 and 2)
  • 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.
