Access Network : Trends






Increasing demand of voice, data and video transmission requires
higher bandwidth.
STM-1 has become access rate. Transmission of 63 2.048 Mbps
tributaries is the most popular application. Driven by GSM, GPRS and
3rd generation requirements.
Increasing demand for higher bandwidth (STM-4)
End to end error performance analysis
Network management capabilities of SDH : Data communication
channels (D1-D12), Orderwire (64 kbit/s voice channels) , User
channels
ADSL deployment has increased the demand of SDH at the access
network as a physical layer for ATM cells transmission.






Handheld test equipment
focused on field testing. Size
