Host trunk configuration

Introduction
Host trunk configuration for the Meridian HomeOffice II system requires telling
your service provider the type of ISDN connection (PRI or BRI) you need and
what parameters to configure. In some situations, under strict limitations, a
T1/E1 trunk may be used.
Recommended trunking option
ISDN PRI is the recommended trunking method for a Meridian HomeOffice II
system.
ISDN PRI configuration
ISDN PRI trunks at the host site are used to transport calls between the host site
and the public switched telephone network (PSTN). To ensure full functionality
for all remote sites served by each HLC, verify with your service provider that
the following elements are configured on each trunk:
two-way voice and two-way data capability
Caller ID (allows the security level for the HLC to be Level 2 - Caller ID)
end-to-end digital circuitry, no analog segments (check with both long-
distance and local service providers)
non-blocking configuration (ensure that configuration will not block
HomeOffice II traffic)
T1/E1 DTI configuration
When the digital trunks used by the Meridian HomeOffice II system are T1 or
E1, certain characteristics must be included for proper functionality of the
system. Those features are included in the following list:
The connection must be digital end-to-end with no analog segments.
