Chapter 21: TDM Services and Interfaces (CLI)
TDM Overview (CLI)
PTP 820G and PTP 820F provides integrated support for transportation of TDM (E1/DS1) services with an
integrated E1/DS1 interface.
Two types of TDM services are supported using the same hardware:
•
Native TDM trails
•
TDM Pseudowire services (enabling interoperability with third party packet/PW equipment)
PTP 820G and PTP 820F also offers hybrid Ethernet and TDM services. Hybrid services can utilize either Native TDM
or pseudowire.
Hybrid Ethernet and TDM services can also be transported via cascading interfaces. This enables the creation of
links among multiple units in a node for multi-carrier and multi-directional applications
