Standard 1.0 System Administration Guide January 1998
• The first choice is the WATS route.
• The NCOS/FRL assigned to the first choice (2) is
compared to the NCOS/FRL (2) of the station.
• The station’s NCOS/FRL (2) is equal to, or greater than,
the WATS NCOS/FRL (2), so the call is allowed for this
choice.
• If all WATS trunks are busy, then the second choice (CO
trunks) is checked.
• The NCOS/FRL of the CO trunks (3) is compared to the
NCOS/FRL of the station (2).
• The station’s NCOS/FRL (2) is lower than the CO trunks’
NCOS/FRL (3), so the call cannot be completed over CO
trunks.
