9 MARKING OF CABLES
Each cable that is connected to a PBX type ASB 150
should be marked on the cable’s designation holder
with the label set SVH 277 003/4, supplied for this
purpose. The cable TSR 902 0444/1 is supplied with a
designation holder, 860 1839, at the EURO-connector.
This label set contains three label types:
Label 1: This label indicates the abbreviated name
for the PBA to which the cable is to be
connected.
Example of parameter:
Label 2: There is one 2-digit parameter.
This parameter indicates the position of
the PBA-slot in the PBA where the cable
is to be connected.
Example of parameter:
Label 3 There are two 1-digit parameters.
The first parameter indicates the position
of the pin-contact unit on the PBA.
The second parameter indicates the 1/4
of the pin contact.
Example of parameters:
These three labels indicate where the upper part of the
cable is to be connected and are placed on the front
side of the designation holder.
When the label 1 for PBA has a "_" included in the
name, please enter the correct letter with a marker
pen.
10 INTERNAL MDF
(Main Distribution Frame)
The BDV BS 101 01 is factory equipped with a Krone
snap-in holder accommodating a maximum of 8 Krone
connectors, which can be snapped-in if desired. Use
pre-fabricated MDF cables (TSR BS 902 0001/800) to
connect the boards in the swivel shelf with the MDF.
The bottom row is intended for interconnections, e.g.
earth connection of the BTU-A_ to the incoming PTT
earth wires or connections to the CPU I/Os. The Krone
connector above is reserved for the trunk lines that
can be equipped with surge protection.
Be sure to fasten the cable clip at the bottom of the
swivel shelf after installation before mounting the cover
of the swivel shelf.
An additional MDF holder is available and orderable
that can be mounted within the exchange in the space
provided for the battery case.
Place the cables according to the figure below. Secure
the cables to the MDF cabinet with adhesive anchors
and bounding cord.
NOTE: There must be a ground connection for
the MDF cabinet when surge protectors
are used.
