Input Connections

The Decoder has the following inputs:
Two ASI copper interfaces for operation up to 160 Mbit/s for 188 byte packets and 160 Mbit/s
for 204 byte packets.
The Telco receiver has a BNC connector for direct reception of TTV G.703 Telco packages
over a PDH network.
NOTE...
For ATM AAL-1 E3 and ATM AAL-1 DS3 systems, two BNCs may be provided for full duplex
operation.
1.4.3

What the Decoder Does

The ASI interfaces are used to present the transport stream in the format required by the
internal Decoder circuitry. At this point, the operation of the unit is the same as the Satellite
Receiver.
