Add DCS Interface
This section includes general information on adding the DCS interface and the Task List: Add DCS.
Systems in a Distributed Communications System (DCS) network are interconnected by both tie trunks (for voice communications) and data links (for control and transparent feature information). These data links, also called DCS signaling links, support the feature transparency.
Various subsets (depending on the specific configuration) of DS1 Interface circuit packs (including TN464F, TN767E, and TN760E) provide the voice-communications interface. The TN799x Control LAN (C-LAN) circuit pack provides the data link interface (between the processor and the physical signaling link).
The C-LAN TN799x circuit pack combines the functions of the P-GATE and PI circuit packs into one circuit pack. The P-GATE or PI is used with the C-LAN to create an X.25-to-TCP/IP bridge for adjunct and DCS connectivity.
In some configurations, the TN799x passes the signaling information over a separate ethernet network (usually via a hub) to adjuncts applications such as CMS, Intuity, and DCS Networking. The C-LAN circuit pack has one Ethernet connection and up to 16 DS0 physical interfaces for PPP connections. In addition to the ethernet functionality, C-LAN extends the ISDN capabilities by providing packet bus access. For use with an ethernet network, connect the appropriate pins of the I/O field to the hub. For pinouts and diagrams, refer to Connector and Cable Diagrams (Pinout Charts).
In other configurations, the TN799x circuit pack carries signaling over point-to-point protocol (PPP) for subsequent inclusion (via the switching fabric) in the same DS1 bitstream as the DSC voice transmissions.
A remote socket control link (RSCL) links the C-LAN and the SPE to pass call control and other management information. Because one link serves all the ports on the circuit pack, RSCL maintenance is part of the C-LAN circuit pack maintenance.
As an option to the TN768 Tone-Clock, a TN780 Tone-Clock circuit pack (installed in the PPN) can interface external Stratum 3 synchronization for DS1 connections.
For further information about DCS, refer to the DEFINITY ECS Administration for Network Connectivity .
