MSN Multiple Subscriber Number. This is a telephone number
associated with an ETS 300 BRI line. Providers of ETS 300 often
give you three MSNs with a BRI, although additional MSNs can
be purchased. An ISDN terminal will "ring" (provide an alerting
signal) only when calls are made to the MSN (or MSNs) entered
in that terminal. If a terminal has no MSNs entered it will "ring"
wheneverthere is a call to any of the MSN’s on that BRI. See ETS
300 and Directory Number.
