ATM Network Interface Option Module
(M2/EOM2/ATMS155_…)
3.7.1 Overview
The ATM
6
Network Interface Module allows the Encoder to transmit and receive MPEG-2
transport streams over broadband telecommunications networks (B-ISDN) using ATM.
There are different variants of the ATM Network Interface Module. The module comprises an
ATM Network Interface (common to all models) and a Physical Layer Module suitable for the
application required. Refer to
for details of the variants. Menus associated with the
ATM Modules are described in
Chapter 4, Operating the Equipment Locally
.
3.7.2 Assembly
To provide the interface to the B-ISDN Telecommunications network, the Physical Layer
Module must be installed according to the type of network required. These are described in
Section 3.7.4, Technical Specification
