9.10 ISDN Channel Modules
9.10.1 ISDN S0F
The ISDN S0F modules (with remote power supply) are used for setting up duplex point-to-point
connections between ISDN PBXs via XMP1 or as subscriber extension of a PBX.
Bit rate 192 kbit/s
Interface 4-wire, capable for bus operation
Impedance 100
Number of interfaces on the module 4
9.10.2 ISDN UQF (4) UK0(Q)
The transmission procedure used is the standardized ISDN echo cancellation procedure.
The 2B1Q code with remote power supply is available.
Using the ISDN UK0Q module, it is possible to set up a UK0-UK0 or Uk0-S0 connection between
private branch exchanges (PABX-PABX) via XMP1 systems. Two UK0 interfaces interconnected
via the XMP1 system ensure the information exchange between e.g. 2 NTBAs or 2 PABXs required
for this purpose.
