T reference points
The T reference point connections provide a point-to-point
digital connection between the ISDN network and Norstar.
A T loop provides lines that can be shared by all Norstar
telephones, peripherals and applications, and ISDN TE.
A T loop can be used in combination with an S loop to provide
D-packet service for a point-of-sale terminal adapter (POSTA)
or other D-packet device. D-packet service is a 16 kbps data
transmission service that uses the D-channel of an ISDN line.
To deliver D-packet service, a network connection (T loop) is
programmed to work with a terminal connection (S loop). The
loops must be on the same physical card. For example, if the
network connection is a loop found on the BRI Card in Slot 1,
the terminal connection must be a loop found on the same card
