ES, SES, and UAS
The quality of service on a given DS-1 trunk is reflected in the ES, SES, and
UAS data parameters.
States
DS-1 trunk states are as follows:
INSV—in-service
MANB—manual busy
SYSB-T—system busy
UNEQ—unequipped (trunks are offline)
Maintenance and error thresholds are datafilled in table CARRMTC (refer to
the DMS-250 Data Schema Reference Manual).
TRAVER enhancements
Translation verification (TRAVER) is a tool that simulates a call from a
user-specified origination to a user-specified destination. TRAVER displays
the contents of all translation and routing tables used; it can also display
each element of the route list with digits outpulsed, if any. This helps in
verifying and correcting datafill.
TRAVER reflects the additional translation tables accessed by PRA250 and
ISA. The additional translation tables needed for PRA250 do not affect
translations for PRA250 trunks.
Originations on PRA250 trunks
The TRAVER command line accepts data needed to make originations on
PRI trunks. The TRAVER command line format is
>TRAVER <ORIG> |<NPI>| <DIGITS> |<OPT>| <TRACE>
The fields NPI and OPT are used for calls originating on a PRI trunk. These
fields do not affect any other type of trunk agency. The OPT field contains
the following information:
network-specific facilities (mandatory)
bearer capability (optional)
With this information (usually contained in the Q.931 SETUP message),
TRAVER is able to follow the path that the translations would follow for
PRI on the DMS-250 switch.
For more information on the TRAVER command, refer to DMS-250
Commands Reference Manual.
