                                          ISDN TESTER AND ANALYZER D2000

PRO

/D2000Lite/D2000 

 

Listed below, the type of interfaces supported by the devices: 

Basic Access 2B+D over Uko/So/To according to ETS 
300 012 – ITU-T I.430 – ETR 080 standards. 

Primary Access 30B+D over S2/T2 with CRC4 control 
according to ETS 300 011, G.704 standards. (Only for 
D2000

PRO

 and D2000Lite). 

Primary Access 30B+D over S2/T2 according to ETS 
300 011, G.704 standards, without CRC4 control. (Only 
for D2000

PRO

 and D2000Lite). 

2Mbit access with line code G.703 in UNFRAMED mode. 
(Only for D2000

PRO

 and D2000Lite).  

Access over synchronous interface according to V.35 - 
V.36 - V.11 (X.21) - V.24 - CODIRECTIONAL standards. 
(Only for D2000

PRO

).  

Access over analog telephone line with 2 wires physical 
interface. (Only for D2000

PRO

 and D2000).  

Accesses BRI, PRI (CRC4) and PRI support signalling protocols over D channel at 
common channel (CCS) as reported in specification, moreover, the same interfaces 
support LEASED connections (e.g. PCM30, PCM30CRC, PCM31, PCM31CRC). 

 

With the VX2000 option, the D2000

PRO

 is able to perform tests over WAN/datacom 

lines with a bit rate up to 2.048 Mbit/s. 

Thanks to the possibility to emulate both DTE (Data Terminal Equipment) and DCE 
(Data Communications Equipment), the D2000

PRO

 allows to carry out quality tests, 

bit error rate (BER), in end-to-end mode over datacom line, or checks toward the 
User’s DTE (CSU, router, or other WAN equipment).  

The criteria monitoring and the possibility to manage local loops (LL), allow to 
extend controls over datacom line.
