Administration for Network Connectivity

555-233-504 — Issue 1 — April 2000 

CID: 77730

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.

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.
