These facilities can be either CCS7 IMT trunk groups with the DDI field
marked in table TRKGRP as either MIXED or DATA, or another ETSI PRI
trunk group. If an appropriate digital trunk cannot be found, the call is
blocked. The call is routed to GNCT treatment if DDI field is datafilled as
voice.
For data calls, supplementary/account code collection (through both
in-switch and NCS/DAP means) can be overridden. This is controlled by
tables LTCALLS and MLTATTR.
In-switch account code collection
When datafilled as PRISM calls, the account length of 1 is not supported in
table AUTHCODM.
User-to-user information services
User-to-user information (UUI) service allows the transport of user-specific
information between ISDN users across the network. The DMS-250 does
not interpret the UUI; it only transports it. This service operates by means of
the UUI information element.
NCID
The DMS-250 switch creates a new network call identifier (NCID) on ETSI
PRI originations.
Dialable Wideband Service
ETSI PRI does not support Dialable Wideband Service.
EIR on ETSI PRI
ETSI PRI supports Enhanced International Routing (EIR). There is no
additional datafill.
