Lucent Technologies 555-230-024 NT Qsig Peer Protocol, Full Etsi Functionality, Automatic TEI

Trunk Group Features

BRI connections through the public network, with a TN2185 on each end of the leased connection. R6 will not, however, allow customers to administer both end- points and trunks on the same TN556C circuit pack.

NT QSIG Peer Protocol

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

Full ETSI Functionality

The full set of ETSI public-network and private-network ISDN features is officially supported. This includes Lookahead Interflow, Lookahead Routing, and Usage Allocation (including the R5 enhancements). It also includes all QSIG supple- mentary services supported through Release 6:

■Name Identification

■Call Diversion (including rerouting)

■Call Transfer

■Path Replacement.

It does not include

■DCS

■Non-Facility Associated Signaling

■D-Channel Backup,

■Wideband Signaling.

Automatic TEI

The user side will support automatic TEI assignment by the network. Both fixed and automatic TEI assignment will be supported on the network side.

TEI: Termination Endpoint Identifier (part of ISDN terminology).

Layer 1 Deactivation

Layer 1 Stable — 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.
