Switch connectivity, LAN connectivity

18Chapter 2 600r server description

In the previous diagram, the telephony LAN (TLAN) subnet provides IP connectivity between the CS 1000 system and the IP Phones. 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 CS 1000 system and IP Phone bandwidth and network requirements, see the planning and installation documentation for the CS 1000 (NN430xx).

Switch connectivity

For more details about how the connection between the 600r server and the switch is established, refer to the switch and server setup document for your switch.

•Meridian 1 and CallPilot Server Conﬁguration (NN44200-302)

LAN connectivity

The 600r server contains two Ethernet controllers on the motherboard that provide the following:

•10/100Base-T Ethernet network connectivity to the ELAN subnet

ELAN subnet is a network connection from the switch to the CallPilot server. The ELAN subnet is an Ethernet LAN that enables signaling and administration access to applications related to the Meridian 1 switch or CS 1000 system. The ELAN subnet is an isolated 10BaseT subnet required for management trafﬁc and intra-system signaling trafﬁc between the system call server and any devices requiring call server processing. A number of conﬁgurations are available, depending on whether the switch has an address on the Nortel server subnet.

For information about the ELAN subnet’s purpose and requirements, see the Planning and Engineering Guide (NN44200-200).

•10/100/1000Base-T Ethernet connectivity to the Nortel server subnet

Nortel server subnet is a network set up by a customer for its data network. The Nortel server subnet is an optional connection that provides data connectivity among desktop and Web messaging clients, administrative PCs, and the CallPilot server. Typically, a Nortel server subnet already exists before CallPilot is installed at a customer site. Nortel recommends that the customer separate the Nortel server subnet from the rest of the enterprise IP network by a Layer 3 switch. The Nortel server subnet connects to the CLAN port on the 600r CallPilot server.
