Lineside Cards; Mg 1000B Data Networking - Avaya 1000 Installation And Commissioning Manual

Overview

Lineside cards

MG 1000B supports the following lineside cards:
• NTD514 line side T1
• NTD534 line side E1
For further information about Lineside T1/E1 cards, refer to Avaya Circuit Card Reference,
NN43001-311.

MG 1000B Data Networking

MG 1000B with a Gateway Controller communicates with the Main Office Call Server using the built-
in Ethernet ports on the Gateway Controller. The Ethernet ports on the Gateway Controller are
• CE: Connection to Server ELAN port ( card only)
• CT: Connection to Server TLAN port ( card only)
• 1E: ELAN connection to the data network (layer 2)
• 2T: TLAN connection to the data network (layer 2)
• E: ELAN connection for dual-homed
• T: TLAN connection for dual-homed
Note:
The CP MG card functions as a Server and Gateway Controller. The CP MG card CE and CT
Ethernet connections are embedded internal on the card. You do not require external cables to
network the Server to the Gateway Controller on a CP MG card.
You must connect the Gateway Controller to a Layer 2 switch to handle signaling between the Main
Office Call Server and the MG 1000B. If the 1E/2T and the E/T Ethernet ports are connected to a
separate Layer 2 switch, the MG 1000B can remain operational if one of the Layer 2 switches fails.
The MG 1000B must have a data network connectivity to the ELAN port of the Main Office Call
Server. The design of the data networking configuration is outside the scope of this document. The
engineering of the data network is documented in the Avaya Converging the Data Network with
VoIP Fundamentals, NN43001-260.
The MG 1000B with Gateway Controller by default supports Auto Negotiate mode on the embedded
Ethernet interfaces; you must configure the networking equipment to which they connect as Auto
Negotiate. If the Gateway Controller Ethernet ports do not auto-negotiate to 100 Mb Full Duplex, an
alarm occurs. A CLI command is also available on the Gateway Controller to turn off auto-
negotiation for the embedded Ethernet interfaces, which configures the interfaces to 100 MB Full
Duplex. No other speed or duplex options are available on the Gateway Controller.
MG 1000B Data Network Topology illustrates an example of a robust network topology.
