This section discusses the station equipment used with the Coral IPx Office including
both wired, wireless, and VoIP stations.
Wired Stations
Each station peripheral card provides an I/O Champ TM connector.
Connections to Coral IPx Office system station equipment are established by
cross-connecting the station circuit from the appropriate Coral IPx Office I/O cable
punch block to the corresponding station wiring punch block.
Table 5-2 lists the various station interface cards available for the Coral IPx Office
system, the type of station equipment that the card supports, and the number of wire
pairs required by the station interface.
Station wiring between the Coral IPx Office system MDF and the station equipment
should contain at least two, and preferably three wire pairs to ensure adequate wiring
capacity. At the station location, the station wiring should be terminated with a
modular, six position, telephone jack, containing at least four conductors (pins 2, 3, 4,
and 5).
Figure 5-3 illustrates typical jack configurations with wire designations for four
station types:
„
2-wire single-line telephones SLT and digital station sets (FlexSet, APDL,
CPA) need only connect Tip [T] and Ring [R] or <UpA> and <UpB> as
shown.
„
FlexSet 280 series or FlexSet APDL units with PEX or PEX+APA need an
extra two wires when power is supplied through the line connector. The
polarity of this connection is irrelevant. When using the TPS (single unit
Telephone Power Supply), no additional wires are required.
For peripheral device installation, refer to the Coral Terminal Equipment Installation
Manual .
