Huawei FTTx Leased Line Solution

Copper Access for Business

EDTB board in Huawei OLT will be adopted, which can support 16 E1 ports and 16 G.SHDSL ports concurrently in one board;

100% inherit the legacy service, don’t need change customer premise equipment;

Application Scenarios:

EDTB is mainly applied for extending E1 coverage by transferring to G.SHDSL;

Both TDM G.SHDSL and E1 interface can support PBX access;


E1 for access and TDM PWE3 for uplink can also be applied;

Native TDM + TDM PWE3

Scenario description:
MA5612/MA5628 access enterprise with TDM E1 interface, and access to Huawei MA5600T with Native TDM mode;

MA5600T access to upper layer PSN network after encapsulating Native TDM to PWE3;

MA5600T or CX600 terminates the PWE3 back to Native TDM to other part of the enterprise.

Clock solution description:
OLT have two ways to get the clock source in this scenario:  Synch Eth  and BITS;

OLT deliver the clock signal to ONU through GPON line clock,  then ONU deliver clock to base station through synch eth or specified clock interface;

Advantage:
PW encapsulation is centralized in OLT, which simplify Huawei ONU function and reduce the total CAPEX;


High accuracy clock from BITS and synch eth can fully meet the base station requirement ;
