1.5.1. Available accesses
Listed below, the type of interfaces supported by the devices:
ACCESS DESCRIPTION
BRI Basic Access 2B+D over Uko/So/To according to ETS
300 012 – ITU-T I.430 – ETR 080 standards.
PRI (CRC4) Primary Access 30B+D over S2/T2 with CRC4 control
according to ETS 300 011, G.704 standards. (Only for
D2000
PRO
and D2000Lite).
PRI Primary Access 30B+D over S2/T2 according to ETS
300 011, G.704 standards, without CRC4 control. (Only
for D2000
PRO
and D2000Lite).
Unframed
G.703 2Mbit access with line code G.703 in UNFRAMED mode.
(Only for D2000
PRO
and D2000Lite).
V/X
Access over synchronous interface according to V.35 -
V.36 - V.11 (X.21) - V.24 - CODIRECTIONAL standards.
(Only for D2000
PRO
).
POTS 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).
1.5.2. V/X Interface (VX2000 Option)
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.
