Chapter 1 Introducing the VOP

The VOP uses Session Initialization Protocol (SIP) for network signaling to
establish or tear down a voice call. Dual-Tone Multi-Frequency (DTMF) signals are
also translated into SIP signals (or transmitted in the voice band).
Advanced call features such as call transferring and call waiting are integrated to
ease next-generation network migration and access network deployment. To
further simplify migration towards an all-IP network, the VOP's FXS line interface
can co-exist with ADSL service on the same copper wire. Metallic Line Testing
(MLT) is also available for copper loop diagnostics.
1.2 Applications
These are the main applications for the VOP:
Phone services for Multiple Tenant Units (MTU).
Phone services for fiber-to-the-building (FTTB) and fiber-to-the-curb (FTTC)
applications.
