2215 Clock Converter
This unit has been designed to provide clock conversion between ANSI and ETSI timing frequencies and vice-versa, and is currently used by a worldwide telecoms provider.
Specifically, the unit converts between the two system rates as follows:
(a) from a 1.544Mbit/s input, generate a synchronous 2.048MHz clock.
and simultaneously
(b) from a 2.048MHz clock input, generate a synchronous 1.544Mb/s output.
NetworkEOW Phone
Nortel NetworkEOW sets a new standard for Engineering Order Wire Telephony. Using the management channel on SDH network nodes communication using H.323 enables different muxes in the hierarchy to be accessed by a common telephone system. Wherever the management channel is routed, the Network EOW can access other similar phones and the advantages of a full feature phone can be exploited. The project was completed by A.R.G to meet a Nortel patent using the carcass of a standard Meridian Telephone.
2010 SDH/PDH Demux
The Demux product is one which integrates both SDH and PDH functionality: Whilst there is a logical split between the two seperate functions, there is overlap in certain areas. This allows the demultiplexing route, synchronous or plesiochronous or a combination of both to be actively selected.
The Demux shall therefore:
- derive 2/34/140Mb/s signals from the 155Mb/s STM-1 SDH physical interface and combinations - up to the total allowable bandwidth.
- derive 2Mb/s signals from the plesiochronous digital line rates: 34M/bs and 140Mb/s. Again up to the total allowable bandwidth.
- derive 2Mb/s signals from routes which traverse through both SDH and PDH functionality: for example a 140Mb/s signal can be derived by the SDH functional section, after which it then feeds into the PDH section whereupon it is demultiplexed down to the primary rate levels; similarly for the 34Mb/s signals.
