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

Other ISDN BRI equipment: NT1
The NT1 (network termination type 1) connects an S interface 
(four-wire) to a U interface (two-wire). In most cases, it 
connects loops from a BRI-ST card to the network connection, 
which uses the U interface. It can also connect S interface 
terminal equipment (TE) to the U loop from a BRI-U2 or 
BRI-U4 Card.
An NT1 is not required to connect from the network to BRI-U 
Cards or to connect U interface TE to an...
