Technical Specifications
BRI interface in accordance with ITU-T I.430
Automatic detection of the protocol and the configuration of the access:
- Point-to-point (P-P)or point-to-multipoint (P-MP) - DSS1, 1TR6, BILINGUAL,
Cornet-T or NO protocol
Protocols: DSS1, 1TR6, Cornet-T / N, QSIG(B.C.), X.25(D)
Display of Layers 1-2-3 and the B-channel status (free/busy) Telephone
functions with the Call hot-button - call number memory for 10 numbers
or keypad protocol commands, X.31 test number, own number - displays
for incoming calls: calling and called number, B-channel, ISDN service,
type of number and numbering plan, display info elements, SUB address
and UUS-1 data - displays during call: AOC-D in currency or charging
units, display info elements, DTMF data - at end of call: AOC-E in currency/
charging units - clearing cause by number/text incl. location Selectable
B-channel, en-bloc or overlap signaling Measurement of Call Set Up time
Selectable call parameters for outgoing calls - type of number and numbering
plan - screening and presentation indicator
Terminal simulation for different ISDN services - bearer speech, audio
3.1, audio 7 kHz, data 64 k - teleservices tel. 3.1, tel. 7 kHz, fax
G3/4, BTX, Teletex, video... Automatic Service Test: determines which
ISDN services are available on the send and receive sides of the access
Automatic test of the supplementary services - for 1TR6: interrogation
of supplementary services - for DSS1: automatic tests of CLIP, CLIR,
COLP, COLR, HOLD, TP, CFU, CFB, CFNR, AOC-D/E, CCBS, CCNR, ECT, 3Pty,
DDI, SUB, UUS, support of keypad protocol. |
Technical Specifications (cont.)
Bus status test with interrogation, display and clearing
of the active call diversions CFU, CFB, CFNR for all services
Automatic X.31(D) test: "Packet data in D-channel" available
? - automatic detection of the TEIs activated in the frame handler -
simulation of X.31(D) terminal to X.25 network
BERT bit error test with evaluation in accordance to G.821/G.826 - extended
self-call or end-to-end BERT - two concurrent BERT on B1 and B2 - loop-box
for B1/B2 simultaneously - displays the bit error count and remaining
measuring time - manual injection of bit errors, measurering time: 1
min.- infinite - QRS test pattern acc. O.150: 2E11-1, 2E15-1, user defined
- selectable service for BERT connection - G.821 analysis: ES, EFS,
SES, US, DM and OK evaluation - G.826 analysis: EB, ES, SES, BBE, SDP
and OK evaluation - adjustable OK/Not-OK bit error rate threshold and
evaluation - audible alarms for bit errors and loss of QRS sync., LOS
counter Tests of ISDN leased lines: Telephone function and BERT - selectable
B-channel (B1 or B2) and two BERT simultaniously - BERT in D-channel
- loopbox function for both B-channels - measurement of round trip delay
and interchannel delay
Layer 1 tests: measurement and evaluation of the phantom feed (OK, NORMAL
or Restricted Power) and the L1 signal level Display of Layer 1 Info
S0- Info S4
Bus installation tests: Checks the correct bus terminating resistors,
finds short circuits, crossed and broken lines, results in clear text. |
