the fibre optic (FO) connection to/from the Phoenix G2 IDU. The ASI EMM module features 4 x
ASI built-in ports (one BNC per ASI channel) and 2 x SFP 1000Base-SX ports.
The compact, simple to configure, and easily scalable design enables cascading with other
EMM extension devices (e.g. ASI EMM and/or E1/T1 EMM). The configuration is performed in
the web GUI of the IDU, in section
Maximum speed for single ASI channel is 216 Mbps. The actual ASI channel speed is auto-
detected by the system and is displayed in
section.
Each ASI channel can be independently configured into Tx or Rx mode. Following port
combinations are possible:
4x ASI Tx (unidirectional)
3x ASI Tx and 1x ASI Rx (bidirectional)
2x ASI Tx and 2x ASI Rx (bidirectional)
1x ASI Tx and 3x ASI Rx (bidirectional)
4x ASI Rx (unidirectional)
Up to 4 EMM modules can be connected into the cascade and thus get the maximum quantity
of external ports (ASI EMM and E1/T1 EMM modules combination is possible). Maximum 4
EMM modules can be cascaded and in case of ASI EMM modules the maximum count of ASI
channels is 16. SFP 1000Base-SX on the left side
SFP 2 UPLINK 2
is dedicated for the modules
interconnection into cascade. The configuration of all EMM modules is performed from the
web GUI of the IDU.
ASI EMM extension module has following interfaces/connectors:

4xDVB ASI ports
Four configurable Input / Output DVB-ASI ports (75 Ohm).
SFP 1 UPLINK 1
Primary SFP port reserved for connection to the IDU or to primary EMM extension module in
EMM extension module chain.
SFP 2 UPLINK 2
Secondary SFP port reserved for connection to secondary / next EMM extension module in
EMM module chain or for connection to relay IDU in add/drop configuration.
DC port
48V power supply connection. Input DC voltage operating range is -20V to -72V (max current
up to 3A). 2-wire DC power connector with screw terminals included. Polarity layout indicated
