Installation and Operation Manual
VoIP Gateway
5
IMPORTANT:
When a mains lead is used (European versions) only connect the VoIP
Gateway to the wall socket using an IEC320/EN60320 – C5 type
connector.

Pin Assignments for the ISDN Interfaces (PRI)
The PRI interfaces are default in TE mode but can be switched to NT mode from the
VoIP Gateway GUI. The pin assignments will change if NT Mode is chosen instead of TE
mode. It will also change depending on the selection of Clock Mode. (Derived from NT,
Slave, Master). See the table below.
TX/RX Leads
Note that the TX/RX leads always follow the clock source. If we are receiving clock, then
the TX leads are pins 4&5. If we are providing clock, the TX leads are 1&2.
2.6
Management port
The Ethernet 1 port can be used for management of the VoIP Gateway. Use standard
CAT5 Ethernet cable.
