Introduction
The PRI Gateway with Media Gateway Controller (MGC) communicates
with the Call Server using the built-in 100BaseT network interface on the
MGC.
Three network interface ports on the MGC can be used for connecting to
the ELAN subnet: two for use by the dual-homing feature and one for a
direct connection to the E1/T1 card.
The E1/T1 card serves four to eight spans and is a motherboard to
the NTBK51AA/NTBK51CA downloadable D-channel handler and the
NTAK93AB D-channel handler. The E1/T1 card requires the lower slot on
the 19-inch 2u chassis. The upper slot is reserved for the MGC.
The MGC can be connected to a Layer 2 switch to handle signaling
between the Call Server and the PRI Gateway. If two of the ELAN network
interfaces of the MGC are connected to separate Layer 2 switches, the
PRI Gateway can remain operational in the event of a failure of one of the
Layer 2 switches.
The PRI Gateway must have data network connectivity to the ELAN
network interface of the Call Server. For more information about the
engineering of the data network, see Converging the Data Network with
VoIP Fundamentals.
By default, the PRI Gateway with the MGC supports autonegotiate mode
on the embedded network interfaces; the networking equipment to which
they are connected must be configured as autonegotiate. If the MGC
