Generally, trunk circuits are connected to the Coral IPx 500 system simply by
cross-connecting the trunk interface circuit of a Coral IPx 500 trunk card to the point of
demarcation where the trunk circuits from the Telephone utility Company (TELCO)
appear. For more specific data regarding all trunk types supported by the Coral IPx 500
systems, refer to
page 10-7, Peripheral Card Description
. Refer also to the
Coral Service
and Peripheral Cards Installation Manual.
Protective devices are regularly provided by the TELCO on circuits originating outside
the building. Determine if the TELCO protective devices meet the specifications
provided in
page 5-9, Protection Devices
, and if necessary, install secondary protector
devices which meet these specifications. To be effective, the protective devices, whether
TELCO or customer provided, must be grounded to the same ground point as the
Coral IPx 500 system.
