In the illustration on page 26, the telephony LAN (TLAN) provides IP 
connectivity between the Succession 1000 system and the i2004 Internet 
phonesets. The connection between the Call Server and Media Gateway can 
be point-to-point, or it can be through the LAN, if the system is installed in a 
distributed data network. 
For information about the Succession 1000 system and i2004 Internet 
phoneset bandwidth and network requirements, refer to the Succession 1000 
Planning and Installation Guide
 (NTP 553-3023-210).
For a description of each Succession 1000 system component, see 
“Succession 1000 description” on page 96.
CallPilot CLAN and ELAN network
 setup
The 201i server supports the following network protocols:
„
CLAN: 10/100Base-T Ethernet
A built-in Ethernet controller on the 201i server motherboard provides 
Ethernet CLAN capability. The CLAN provides data connectivity 
between desktop and web messaging clients, administrative PCs, and the 
CallPilot server.
„
ELAN: 10Base-T Ethernet
A built-in Ethernet controller on the 201i server motherboard provides 
Ethernet ELAN capability. The ELAN carries call processing traffic 
between the CallPilot server and the Meridian 1 switch or 
Succession 1000 system. 
Note: For more information about the ELAN, see “About the ELAN” in 
the CallPilot Installation and Configuration Task List.
You use the 201i server multi I/O cable to establish the CLAN and ELAN 
connections. For more information, see page 28.
