Further Information
Refer also to any region specific information on EMC ( Sections
and
4.2.2 on page
19 4.2.5 on page 21 ).
For further information on good EMC practice, the installer should consult the
IEC61000-5-x series of Technical Reports on the subject of Electromagnetic
Compatibility (EMC) - Installation and Mitigation Guidelines. In particular the
following sections are recommended; IEC61000-5-1 - General Considerations,
IEC61000-5-2 - Earthing and Cabling, IEC61000-5-6 - Mitigation of External
EM Influences.
4.3.4 Telecommunications
The telecommunication interfaces of this product are described in Sections
and 3.1 on page 13 6.3 on page 31 . They are primary rate
telecommunications (PCM) interfaces, configurable as E1/T1/J1 interfaces,
with selectable line code and frame format. For information on setting the
product configuration consult the SS7 Boards Programmer’s Manual for
SPCI2S and SPCI4 ∗ . The developer/installer must ensure that they are
configured to give an implementation that complies with the services offered
by the local Public Switch Telephone Network (PSTN) operator. Application
developers implementing supplementary services at application level must
ensure that their implementation complies with the services offered by the
local Public Switch Telephone Network (PSTN) operator. In case of doubt,
network specifications must be consulted. In the European Union, the R&TTE
Directive imposes that each PSTN operator makes such specifications
available.
This product has been successfully tested against TBR12 and TBR13 when
configured for E1 operation. Refer also to other region specific information on
network connection (
Sections 4.2.3 and on page 20 4.2.4 on page 21 ).
The telecommunication network interfaces of this product are not intended for
direct connection to “outside plant” signal conductors (metallic). The product
shall be isolated, by channel banks or office repeaters, from any connections
to network or terminal equipment, that lie outside of the same building. The
telecommunication interface connections are considered to be, and meet the
requirements of, SELV circuits (not TNV).
In order to maintain the host-independent approval for the network interface,
it is essential that, when other option boards are introduced which use or
generate a hazardous voltage (as defined in IEC/EN60950-1), the minimum
creepage and clearance distances specified in
Table 1 on page 24 are
maintained.
The board or assembly holding the network interface must be installed such
that, with the exception of the connections to the host, clearance and
creepage distances shown in the table below are maintained between the
board or assembly holding the network interface, and any part of the host,
including other option boards or assemblies. Failure to maintain these
minimum distances will invalidate the approval.
