Introduction
The I-Gate 4000 PRO is among the industry's first real carrier-class IP Telephony
platforms with carrier-class performance. It is designed to provide all the following
carrier-class features: openness, reliability, scalability, capacity, availability and
fixed line voice quality.
The I-Gate 4000 PRO Media Gateway is divided into two shelves: the lower shelf
containing the Main cards (i.e. Main Hardware section), and the upper shelf
containing the input/output (I/O) interface cards.
The I-Gate 4000 PRO Media Gateway is encased in a 32-slot chassis that complies
with ETSI 300 119 requirements. I-Gate 4000 PRO features front-loading cards and
I/O connections for convenient access to both I/O connections and the cards. There
are no connections at the rear of the terminal. Each interface card has a protective
panel for physical protection and as a guard against electromagnetic interference
(EMI).
Similarly, the Main Hardware section (i.e. lower shelf) provides a door that acts both
as a physical protection and also against electromagnetic interference (EMI). This
feature makes the insertion of blank cards (to occupy empty, unused shelf slots)
unnecessary.
The Main Hardware shelf includes these basic card modules:
!
TDM network Interface Cards
!
Traffic Handling (Main Cards): Signal processing, switching and packet network
interface cards
!
Power feed and alarm cards
Up to three I-Gate 4000 PRO Media Gateway terminals can be installed in a single
cabinet (see Figure 3-2) or up to six I-Gate 4000 PRO Media Gateway terminals in a
back-to-back setup. Other physical characteristics and system specifications are
described in Chapter 3, "Planning Installation Site".
