STS-1 connection provisioning will also besupported on OC-12/OC-48 NEs subtending from the OC-192 4F-BLSR.Note: Open Contract Interfaces support is not available for subtendingNEs.The two areas of connection management functionality are the followings:• Connection Provisioning: Provides the user with the ability to provisionbidirectional STS-1 connections on OC-192 4F-BLSR systems. An STS-1bidirectional connection on a BLSR is defined by:- the two service access points at which traffic terminates,- the STS-1 channel on which the connection is carried, andthe direction of the connection around the ring.• Service Assurance: Involves the management of the STS-1 connectionsprovisioned in the network. It enables the user to obtain a summary ofpreviously provisioned bidirectional connections:- throughout a 4F-BLSR system- on a SONET line between two adjacent ring nodes- terminating at or passing though a specific nodeThe connection provisioning and service assurance capabilities are listedbelow for the ring configuration:- adding/deleting/editing STS-1 level subnetwork connections.- point & click provisioning support for bidirectional STS-1 timeslotassignment (TSA).- capability to view the tributary usage on a specified NE.- capability to view STS-1 channel usage between any two ring NEs.- provisioning OC-12/OC-48 NEs subtending from an OC-192 4F-BLSR.Figure 29 on page 85 shows an example of a configuration and connection.A single-shelf OC-12 TBM mux subtending off an OC-12 tributary of anOC-192 4F-BLSR will be shown as an OC-12 linear point-to-point systemwith one OC-12 NE and one OC-192 NE. A dual-shelf OC-12 TBM muxsubtending off an OC-12 tributary of an OC-192 4F-BLSR will be shown asan OC-12 linear ADM chain with two OC-12 NEs and an OC-192 NE at oneend (Figure 29 on page 85).An end-to-end connection with one end terminating on an OC-12 shelfsubtending off an OC-192 NE and the other end terminating on a differentOC-192 NE will be provisioned as two separate connections - one betweenNEs on the OC-192 configuration and the other from the OC-12 shelf to theOC-192 NE.
