AK500 System Installation and User's Guide
Positron Access Solutions 99 Document 180-0037-003 R01
Note: If line powering is enabled, voltage on MSPAN pairs is either -135Vdc or
-185Vdc.
The effective capacitance of the units between the connection points for the
conductors of the tip and ring is 46.2uF. The effective capacitance of the units
between the connection point for one conductor of tip or ring and earth is 0.25uF.
At the time of installation, a system assessment shall be carried out to ensure
that the effective capacitance of the total system, including the capacitance of the
equipment does not exceed the values specified in Figure 2 of UL60950-21.
At the time of installation, it shall be checked that the voltage rating of the wiring
of the telecommunication network is adequate for the normal Positron unit’s
circuit voltage, together with superimposed transients.
At the time of installation it shall be checked that all multi-pair span circuits to be
connected together are all RFT-V circuits. In practical terms as all equipment
supplied by Positron only uses RFT-V circuits, then it should be checked that the
multi-pair span of Positron equipment is not connected to any other vendor’s
equipment.
WARNING: The intra-building ports of the equipment are suitable for connection
to intra-building or unexposed wiring or cabling only. The intra-building ports of
the equipment MUST NOT be metallically connected to interfaces which connect
to the OSP or its wiring. These interfaces are designed for use as intra-building
interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE, Issue 4)
and require isolation from the exposed OSP cabling. The addition of Primary
Protectors is not sufficient protection in order to connect these interfaces
metallically to OSP wiring.
SUITABLE FOR MOUNTING ON CONCRETE OR OTHER NON-
COMBUSTIBLE SURFACE ONLY.
