China Mobile selects Symmetricom to deploy synchronous Ethernet for PTN deployment

By Telecom Lead Team: Symmetricom, a provider of
precision time and frequency technologies, announced that China Mobile has
selected Symmetricom’s TimeProvider 5000 Grandmaster Clock to deploy
IEEE 1588 (PTP) and Synchronous Ethernet (SyncE) for its Packet Transport
Network (PTN) deployment. 


SyncE provides frequency synchronization for Ethernet
networks and PTP is the standard for providing frequency and phase
synchronization over packet networks to support 4G/LTE deployments.


The growing demand for video and data services have
prompted service providers such as China Mobile to transition from time
division multiplexing (TDM) based network to a Packet Transport Network
(PTN). China Mobile has chosen to deploy SyncE in the network core and PTP
over the top to the base stations.


“As China Mobile continues its PTN network rollout
and evolves towards a smaller cell architecture, we see an increasing role for
PTP as the primary synchronization solution, which will support data traffic
growth while ensuring service continuity for our customers,” said Li Han,
China Mobile
Research Institute.  


Symmetricom solutions provide the synchronization
required by mobile operators for Ethernet backhaul. The TimeProvider 5000
Grandmaster Clock is a packet-based timing and frequency solution that
combines the functionality of a highly-accurate, IEEE 1588 grandmaster clock
with enhancements to support SyncE, Network Time Protocol (NTP), E1/T1 and Time
of Day (ToD).  The TimeProvider 5000 Grandmaster Clock’s flexible
architecture supports both LTE FDD and TDD applications.


“Most operators are managing heterogeneous networks
that require multi-sync capabilities.  Selection of our multi-sync
platform by China Mobile, the world’s largest mobile operator, validates the
solutions’ superior performance and resilience,” said Manish Gupta,
vice president of marketing at Symmetricom.


Symmetricom’s grandmaster clock solutions address a wide
variety of applications designed to support LTE and Carrier Ethernet. These
solutions enable Symmetricom customers to directly benefit from lower-cost,
higher-capacity packet network infrastructures without sacrificing precise
timing and synchronization requirements.
