All administrative lines at BU require PBNs in order to place
long distance calls. PBNs are 5-digits long, and are restricted
by Network Class of Service (NCOS) categories:
- NCOS 13: Allows calls within Massachusetts
- NCOS 22: Allows calls within Continental US, Hawaii, Puerto Rico, Virgin Islands, West Indies
- NCOS 25: North America
- NCOS 28: International
PBNs are non-transferable and are to be used only by the person
to whom the PBN is assigned to. It is the responsibility of University departments
to inform the Office of Telecommunications when faculty or staff
members leave the University, by requesting deactivation of any
active PBNs or Calling Cards assigned to that person.
To add, change, or delete PBNs, a Department Administrator must
send us a PBN Request Form with an authorized signature to the Office
of Telecommunications. Call 3-2097 for assistance or further
information about long distance services at BU.
