14.4.2 E1 Base Station Access Service (in SAToP Mode)

ONUs transmit E1 signals of base stations to OLTs in SAToP mode and OLTs are interconnected
with transmission equipment through E1 ports. In this manner, traditional circuit switching
services can be carried over GPON networks.

14.4.2.1 Service Requirement and Application Scenario

Service Requirement
As a mainstream full-service access technology in the future, the passive optical network (PON)
supports fast deployment and service provisioning. It also helps simplify the access network and
reduce the costs on construction and subsequent maintenance of the access network. Currently,
carriers in China and outside China are using the PON to carry 2G/3G base station services over
their existing FTTx networks that are established for accessing individual/enterprise users. In
this manner, carriers can implement the access of all the services at the access layer in an unified
mode.

Application Scenario
As shown in
through the unified hardware port, and then transmits the service data to the OLT in the SAToP
mode. The OLT restores E1/T1 signals, and then transmits the signals to the SDH network
through the E1/T1 port. In this manner, service access of the 2G or 3G base station is
implemented between the ONU and the OLT in the SAToP mode.
Applicable ONUs: MA5612, MA5628, MA5616

ONUs are connected to 2G or 3G base stations through E1/T1 ports.
GPON is used for carrying the mobile access network in a unified manner to meet mobile
carriers' requirements for a high bandwidth and high-density coverage of base stations.
Existing SDH resources are utilized efficiently to implement high-quality transmission of
TDM services.
