Operations philosophy

Overview

Alcatel-Lucent 1850 TSS-5 has incorporated an operations philosophy that is optimized for operations in the access transport environment. This allows operation and maintenance of remote NEs from a single centralized operations center. It also allows technicians working at remote sites to gain access to NEs at other locations.

Alcatel-Lucent 1850 TSS-5 equipped with the VLNC2 SYSCTL and VLNC50/52/55 SONET/SDH Transport circuit packs uses the SONET or SDH data communications channel (DCC) to provide remote CIT access, remote CO alarms, remote alarm reports, and remote OS access. The terms remote operations, single-ended operations (SEO), and Operations Interworking (OI) are synonymous. Alcatel-Lucent 1850 TSS-5 equipped with circuit packs that are not controlled by the SYSCTL uses a TCP/IP network for remote access to those packs.

SEO capability

The following figure shows the SEO capability that provides remote access via DCC to all Alcatel-Lucent 1850 TSS-5 systems in a subnetwork from a single Alcatel-Lucent 1850 TSS-5 location. This minimizes the need for technician travel because most maintenance, provisioning, and administration can be performed on all NEs with DCC connectivity by accessing any one NE. The SEO capability can be disabled between NEs to create maintenance boundaries (for example, interoffice applications) or for security reasons.
