leased connection. R6 will not, however, allow customers to administer both end-

The NT side of the QSIG Peer Protocol has been added.

The full set of ETSI public-network and private-network ISDN features is officially 
supported. This includes Lookahead Interflow, Lookahead Routing, and Usage

mentary services supported through Release 6:

—

 Tells call processing and maintenance software whether to 

expect the network to drop Layer 1 when the BRI port is idle. When acting as the 
TE side, R6 supports the case where the network deactivates Layer 1 when both 
B-channels of a BRI port are idle. When acting as the NT side, R6 deactivates 
Layer 1 only when the BRI port is busied out.
