E C-LAN Installation

This chapter provides instructions for installing and making the physical connections to the circuit packs that are new for R7 — the C-LAN (TN799) and the NetPkt (TN794) circuit packs. The C-LAN circuit pack is optional for R7 but required for TCP/IP connectivity in all switch models. The NetPkt circuit pack is required for R7 in the si model only.

These instructions are also included in the upgrades and installation documents for each switch model. They are duplicated here for convenience and completeness.

Overview

Systems in a DCS network are interconnected by both tie trunks (for voice communications) and data links (for control and transparent feature information). Various DS1 interface circuit packs (including TN464C, TN767C, TN722, and TN760) provide the voice-communications interface. For TCP/IP connectivity, the data-link interface is provided by a TN799 C-LAN circuit pack.

The C-LAN handles the data-link signaling information in one of two configurations; either 10BaseT ethernet or point-to-point (ppp).

In the ethernet configuration, the C-LAN passes the signaling information over a separate 10BaseT TCP/IP network, usually via a hub. For this configuration, install the C-LAN circuit pack and connect the appropriate pins of the C-LAN I/O field to the hub as described below.

In the ppp configuration, the C-LAN passes the data-link signaling to the DS1 for inclusion in the same DS1 bit stream as the DCS voice transmissions. For this configuration, install the C-LAN circuit pack; no other connections are needed.

In both configurations, the appropriate DS1 circuit packs must be installed if they are not already present.
